It was set up to investigate the feasibility of an ultra-brilliant photoinjector and to perform FEL experiments. The new beamline is equipped with three APPLE-X undulators acting as amplifiers to deliver IR/THz radiation with photon pulses in the ps range, with energy of tens of uJ, and with linear, circular, or elliptical polarization. The APPLE-X guarantees to vary the gap amplitude between the magnets arrays and their relative phase. The entire system has been designed from scratch, and a structural analysis has been carried out. Once they were in Frascati, in collaboration with ENEA, a further investigation campaign was launched on the mechanical, using strain measurements based on optical methods. FBG sensors were suitable for these tests due to their immunity to electromagnetic noise. They consist of a phase grating inscribed in the core of a single-mode fiber, whose Bragg-diffracted light propagates back along the fiber. If bonded to the mechanical structure, they can be used as strain sensors. By following the variations in the scattered spectrum, it is possible to perform strain measurements. Using multiple FBGs applied at selected locations on the undulator, several measurements were while opening and closing the gap or changing the phase, but also by studying the quiescent response as a function of the ambient temperature. The results of these tests show that there is a clear deformation of the structure related to the temperature changes and magnetic forces, but the magnitude of this deformation is well within the tolerances required for the functionality of the undulator since they are compatible or lower with respect to the one calculated with the finite elements methods. The tests confirm the reliability of the mechanical structure. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2501.11531v1-abstract-full').style.display = 'none'; document.getElementById('2501.11531v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 20 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2025. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2309.00351">arXiv:2309.00351</a> <span> [<a href="https://arxiv.org/pdf/2309.00351">pdf</a>, <a href="https://arxiv.org/format/2309.00351">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.dark.2023.101370">10.1016/j.dark.2023.101370 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The future search for low-frequency axions and new physics with the FLASH resonant cavity experiment at Frascati National Laboratories </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Alesini%2C+D">David Alesini</a>, <a href="/search/physics?searchtype=author&query=Babusci%2C+D">Danilo Babusci</a>, <a href="/search/physics?searchtype=author&query=Beltrame%2C+P">Paolo Beltrame</a>, <a href="/search/physics?searchtype=author&query=Bossi%2C+F">Fabio Bossi</a>, <a href="/search/physics?searchtype=author&query=Ciambrone%2C+P">Paolo Ciambrone</a>, <a href="/search/physics?searchtype=author&query=D%27Elia%2C+A">Alessandro D'Elia</a>, <a href="/search/physics?searchtype=author&query=Di+Gioacchino%2C+D">Daniele Di Gioacchino</a>, <a href="/search/physics?searchtype=author&query=Di+Pirro%2C+G">Giampiero Di Pirro</a>, <a href="/search/physics?searchtype=author&query=D%C3%B6brich%2C+B">Babette D枚brich</a>, <a href="/search/physics?searchtype=author&query=Falferi%2C+P">Paolo Falferi</a>, <a href="/search/physics?searchtype=author&query=Gatti%2C+C">Claudio Gatti</a>, <a href="/search/physics?searchtype=author&query=Giannotti%2C+M">Maurizio Giannotti</a>, <a href="/search/physics?searchtype=author&query=Gianotti%2C+P">Paola Gianotti</a>, <a href="/search/physics?searchtype=author&query=Lamanna%2C+G">Gianluca Lamanna</a>, <a href="/search/physics?searchtype=author&query=Ligi%2C+C">Carlo Ligi</a>, <a href="/search/physics?searchtype=author&query=Maccarrone%2C+G">Giovanni Maccarrone</a>, <a href="/search/physics?searchtype=author&query=Mazzitelli%2C+G">Giovanni Mazzitelli</a>, <a href="/search/physics?searchtype=author&query=Mirizzi%2C+A">Alessandro Mirizzi</a>, <a href="/search/physics?searchtype=author&query=Mueck%2C+M">Michael Mueck</a>, <a href="/search/physics?searchtype=author&query=Nardi%2C+E">Enrico Nardi</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Federico Nguyen</a>, <a href="/search/physics?searchtype=author&query=Rettaroli%2C+A">Alessio Rettaroli</a>, <a href="/search/physics?searchtype=author&query=Rezvani%2C+J">Javad Rezvani</a>, <a href="/search/physics?searchtype=author&query=Teofilo%2C+F+E">Francesco Enrico Teofilo</a>, <a href="/search/physics?searchtype=author&query=Tocci%2C+S">Simone Tocci</a> , et al.

Concerning the QCD axion, FLASH will search for these particles as the DM in the mass range (0.49-1.49) ueV, thus filling the mass gap between the ranges covered by other planned searches. A dedicated Microstrip SQUID operating at ultra-cryogenic temperatures will amplify the signal. The frequency range accessible overlaps with the Very High Frequency (VHF) range of the radio wave spectrum and allows for a search in GWs in the frequency range (100-300) MHz. The experiment will make use of the cryogenic plant and magnet of the FINUDA experiment at INFN Frascati National Laboratories near Rome (Italy); the operations needed to restore the functionalities of the apparatus are currently underway. We present the setup of the experiment and the sensitivity forecasts for the detection of axions, scalar fields, chameleons, hidden photons, and GWs. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.00351v1-abstract-full').style.display = 'none'; document.getElementById('2309.00351v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 1 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> CA21106; CA21136 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.Dark Univ. 42 (2023) 101370 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2008.12056">arXiv:2008.12056</a> <span> [<a href="https://arxiv.org/pdf/2008.12056">pdf</a>, <a href="https://arxiv.org/format/2008.12056">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Geophysics">physics.geo-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.cageo.2021.104762">10.1016/j.cageo.2021.104762 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Deep generative models in inversion: a review and development of a new approach based on a variational autoencoder </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Lopez-Alvis%2C+J">Jorge Lopez-Alvis</a>, <a href="/search/physics?searchtype=author&query=Laloy%2C+E">Eric Laloy</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Fr茅d茅ric Nguyen</a>, <a href="/search/physics?searchtype=author&query=Hermans%2C+T">Thomas Hermans</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2008.12056v1-abstract-short" style="display: inline;"> When solving inverse problems in geophysical imaging, deep generative models (DGMs) may be used to enforce the solution to display highly structured spatial patterns which are supported by independent information (e.g. the geological setting) of the subsurface.

In such case, inversion may be formulated in a latent space where a low-dimensional parameterization of the patterns is defined and where Markov chain Monte Carlo or gradient-based methods may be applied. However, the generative mapping between the latent and the original (pixel) representations is usually highly nonlinear which may cause some difficulties for inversion, especially for gradient-based methods. In this contribution we review the conceptual framework of inversion with DGMs and study the principal causes of the nonlinearity of the generative mapping. As a result, we identify a conflict between two goals: the accuracy of the generated patterns and the feasibility of gradient-based inversion. In addition, we show how some of the training parameters of a variational autoencoder, which is a particular instance of a DGM, may be chosen so that a tradeoff between these two goals is achieved and acceptable inversion results are obtained with a stochastic gradient-descent scheme. A test case using truth models with channel patterns of different complexity and cross-borehole traveltime tomographic data involving both a linear and a nonlinear forward operator is used to assess the performance of the proposed approach. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2008.12056v1-abstract-full').style.display = 'none'; document.getElementById('2008.12056v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 August, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2020. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2003.03434">arXiv:2003.03434</a> <span> [<a href="https://arxiv.org/pdf/2003.03434">pdf</a>, <a href="https://arxiv.org/format/2003.03434">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="General Relativity and Quantum Cosmology">gr-qc</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1063/5.0018414">10.1063/5.0018414 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Site-selection criteria for the Einstein Telescope </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Amann%2C+F">Florian Amann</a>, <a href="/search/physics?searchtype=author&query=Bonsignorio%2C+F">Fabio Bonsignorio</a>, <a href="/search/physics?searchtype=author&query=Bulik%2C+T">Tomasz Bulik</a>, <a href="/search/physics?searchtype=author&query=Bulten%2C+H+J">Henk Jan Bulten</a>, <a href="/search/physics?searchtype=author&query=Cuccuru%2C+S">Stefano Cuccuru</a>, <a href="/search/physics?searchtype=author&query=Dassargues%2C+A">Alain Dassargues</a>, <a href="/search/physics?searchtype=author&query=DeSalvo%2C+R">Riccardo DeSalvo</a>, <a href="/search/physics?searchtype=author&query=Fenyvesi%2C+E">Edit Fenyvesi</a>, <a href="/search/physics?searchtype=author&query=Fidecaro%2C+F">Francesco Fidecaro</a>, <a href="/search/physics?searchtype=author&query=Fiori%2C+I">Irene Fiori</a>, <a href="/search/physics?searchtype=author&query=Giunchi%2C+C">Carlo Giunchi</a>, <a href="/search/physics?searchtype=author&query=Grado%2C+A">Aniello Grado</a>, <a href="/search/physics?searchtype=author&query=Harms%2C+J">Jan Harms</a>, <a href="/search/physics?searchtype=author&query=Koley%2C+S">Soumen Koley</a>, <a href="/search/physics?searchtype=author&query=Kovacs%2C+L">Laszlo Kovacs</a>, <a href="/search/physics?searchtype=author&query=Losurdo%2C+G">Giovanni Losurdo</a>, <a href="/search/physics?searchtype=author&query=Mandic%2C+V">Vuk Mandic</a>, <a href="/search/physics?searchtype=author&query=Meyers%2C+P">Patrick Meyers</a>, <a href="/search/physics?searchtype=author&query=Naticchioni%2C+L">Luca Naticchioni</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Frederic Nguyen</a>, <a href="/search/physics?searchtype=author&query=Oggiano%2C+G">Giacomo Oggiano</a>, <a href="/search/physics?searchtype=author&query=Olivieri%2C+M">Marco Olivieri</a>, <a href="/search/physics?searchtype=author&query=Paoletti%2C+F">Federico Paoletti</a>, <a href="/search/physics?searchtype=author&query=Paoli%2C+A">Andrea Paoli</a>, <a href="/search/physics?searchtype=author&query=Plastino%2C+W">Wolfango Plastino</a> , et al.

It will provide about an order of magnitude sensitivity increase with respect to currently operating detectors, and furthermore, extend the observation band towards lower frequencies, i.e., down to about 3Hz. One of the first decisions that needs to be made is about the future ET site following an in-depth site characterization. Site evaluation and selection is a complicated process, which takes into account science, financial, political, and socio-economic criteria. In this paper, we provide an overview of the site-selection criteria for ET, provide a formalism to evaluate the direct impact of environmental noise on ET sensitivity, and outline the necessary elements of a site-characterization campaign. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2003.03434v2-abstract-full').style.display = 'none'; document.getElementById('2003.03434v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 June, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 6 March, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">22 pages, 3 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Review of Scientific Instruments 91, 9, 094504 (2020) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1912.00906">arXiv:1912.00906</a> <span> [<a href="https://arxiv.org/pdf/1912.00906">pdf</a>, <a href="https://arxiv.org/format/1912.00906">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1017/S0022377820001324">10.1017/S0022377820001324 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Slice collective dynamics, projected emittance deterioration and Free Electron Laser performances detrimental effects </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Dattoli%2C+G">Giuseppe Dattoli</a>, <a href="/search/physics?searchtype=author&query=Di+Mitri%2C+S">Simone Di Mitri</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Federico Nguyen</a>, <a href="/search/physics?searchtype=author&query=Petralia%2C+A">Alberto Petralia</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="1912.00906v1-abstract-short" style="display: inline;"> The dynamical effects inducing geometrical and phase space misalignment of bunch slice in X-ray operating Free Electron Lasers can be traced back to a plethora of phenomena, both in the linac accelerating section or inside the beam transport optic magnet.

This paper is the Conceptual Design Report of the KLASH (KLoe magnet for Axion SearcH) experiment at the Laboratori Nazionali di Frascati (LNF). The idea of this experiment has been stimulated by the availability of the large volume superconducting magnet, with a moderate magnetic field of 0.6 T, used in the KLOE detector at the DAFNE collider. The main conclusion we draw from this report is the possibility to build and put in operation at LNF in 2-3 years a large haloscope with the sensitivity to KSVZ axions in the low mass range between 0.2 and 1 $渭$eV, complementary to that of other experiments. Timeline and cost are competitive with respect to other proposals in the same mass region thanks to the availability of most of the infrastructure, in particular the superconducting magnet and the cryogenics plant. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1911.02427v1-abstract-full').style.display = 'none'; document.getElementById('1911.02427v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 November, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2019. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> INFN-19-18/LNF </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1903.00769">arXiv:1903.00769</a> <span> [<a href="https://arxiv.org/pdf/1903.00769">pdf</a>, <a href="https://arxiv.org/ps/1903.00769">ps</a>, <a href="https://arxiv.org/format/1903.00769">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Fluid Dynamics">physics.flu-dyn</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Statistical Mechanics">cond-mat.stat-mech</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Chaotic Dynamics">nlin.CD</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.3390/e21030326">10.3390/e21030326 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Universality and Thermodynamics of Turbulence </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Geneste%2C+D">Damien Geneste</a>, <a href="/search/physics?searchtype=author&query=Faller%2C+H">Hugues Faller</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Florian Nguyen</a>, <a href="/search/physics?searchtype=author&query=Shukla%2C+V">Vishwanath Shukla</a>, <a href="/search/physics?searchtype=author&query=Laval%2C+J">Jean-Philippe Laval</a>, <a href="/search/physics?searchtype=author&query=Daviaud%2C+F">Francois Daviaud</a>, <a href="/search/physics?searchtype=author&query=Saw%2C+E">Ewe-Wei Saw</a>, <a href="/search/physics?searchtype=author&query=Dubrulle%2C+B">Berengere Dubrulle</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="1903.00769v1-abstract-short" style="display: inline;"> We investigate universality of the Eulerian velocity structure functions using velocity fields obtained from the stereoscopic particle image velocimetry (SPIV) technique in experiments and the direct numerical simulations (DNS) of the Navier-Stokes equations.

We show that the numerical and experimental velocity structure functions up to order 9 follow a log-universality; we find that they collapse on a universal curve, if we use units that include logarithmic dependence on the Reynolds number. We then investigate the meaning and consequences of such log-universality, and show that it is connected with the properties of a "multifractal free energy", based on an analogy between multifractal and themodynamics. We show that in such a framework, the existence of a fluctuating dissipation scale is associated with a phase transition describing the relaminarisation of rough velocity fields with different Holder exponents. Such a phase transition has been already observed using the Lagrangian velocity structure functions, but was so far believed to be out of reach for the Eulerian data. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1903.00769v1-abstract-full').style.display = 'none'; document.getElementById('1903.00769v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 March, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2019. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1805.00081">arXiv:1805.00081</a> <span> [<a href="https://arxiv.org/pdf/1805.00081">pdf</a>, <a href="https://arxiv.org/format/1805.00081">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Biological Physics">physics.bio-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Fluid Dynamics">physics.flu-dyn</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevE.98.042419">10.1103/PhysRevE.98.042419 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Impacts of multiflagellarity on stability and speed of bacterial locomotion </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Nguyen%2C+F+T+M">Frank T.

The elasticities of both the hook protein (connecting cell body and flagellum) and flagella are varied. Flexibility plays contrasting roles for uni- and multiflagellar swimmers. For a uniflagellar swimmer, hook and/or flagellar buckling occurs above a critical flexibility relative to the torque exerted by the flagellar motor. Addition of a second flagellum greatly expands the parameter regime of stable locomotion, because flexible hooks that would lead to buckling instability in the uniflagellar case provide the flexibility required for flagellar bundling in the biflagellar case. Similar observations hold for tri- and quadriflagellar swimmers. Indeed the stability regimes for uni- and quadriflagellar swimming are virtually inverted -- to a first approximation what is stable in one case is unstable in the other. Swimming speed is also examined: it increases very weakly with number of flagella and a simple theory is developed that explains this observation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1805.00081v3-abstract-full').style.display = 'none'; document.getElementById('1805.00081v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 October, 2018; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 30 April, 2018; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2018. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Physical Review E, to appear</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

In the Resonant Multi-Pulse Ionization injection (ReMPI) a resonant train of pulses drives a large amplitude plasma wave that traps electrons extracted from the plasma by further ionization of a high-Z dopant (Argon in the present paper). While the pulses of the driver train have intensity below the threshold for the dopant's ionization, the properly delayed and frequency doubled (or more) ionization pulse possesses an electric field large enough to extract electrons, though its normalized amplitude is well below unity. In this paper we will report on numerical simulations results aimed at the generation of GeV-scale bunches with normalized emittance and {\it rms} energy below $80\, nm \times rad $ and $0.5\, \%$, respectively. Analytical consideration of the FEL performance for a $1.3\, GeV$ bunch will be also reported. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1802.09838v1-abstract-full').style.display = 'none'; document.getElementById('1802.09838v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 February, 2018; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2018. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">EAAC 2017 Conference, Elba, Italy</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> NIMA_PROCEEDINGS-D-17-00157R1 (2018) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1801.08717">arXiv:1801.08717</a> <span> [<a href="https://arxiv.org/pdf/1801.08717">pdf</a>, <a href="https://arxiv.org/format/1801.08717">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.nima.2018.01.094">10.1016/j.nima.2018.01.094 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> EuPRAXIA@SPARC_LAB Design study towards a compact FEL facility at LNF </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Ferrario%2C+M">M.

Non-axisymmetric stratorotational instability (SRI) is known to set in for anticyclonic rotation ratios beyond that line, i.e. $畏^2<渭<1$ for axially stably-stratified Taylor-Couette flow, but the competition between CI and SRI in the range $渭<畏^2$ has not yet been addressed. In this paper, we establish continuous connections between the two instabilities at finite Reynolds number Re, as previously suggested by M. Le Bars & P. Le Gal, Phys. Rev. Lett. 99, 064502 (2007), making them indistinguishable at onset. Both instabilities are also continuously connected to the radiative instability at finite Re. These results demonstrate the complex impact viscosity has on the linear stability properties of this flow. Several other qualitative differences with inviscid theory were found, among which the instability of a non-axisymmetric mode localized at the outer cylinder without stratification, and the instability of a mode propagating against the inner cylinder rotation with stratification. The combination of viscosity and stratification can also lead to a `collision' between (axisymmetric) Taylor vortex branches, causing the axisymmetric oscillatory state already observed in past experiments. Perhaps more surprising is the instability of a centrifugal-like helical mode beyond the Rayleigh line, caused by the joint effects of stratification and viscosity. The threshold $渭=畏^2$ seems to remain, however, an impassable instability limit for axisymmetric modes, regardless of stratification, viscosity, and even disturbance amplitude. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1607.00272v2-abstract-full').style.display = 'none'; document.getElementById('1607.00272v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 21 September, 2016; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 1 July, 2016; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2016. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

IRIDE will be a high intensity 'particle factory', based on a combination of a high duty cycle radio-frequency superconducting electron linac and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of science and technology. IRIDE will contribute to open new avenues of discoveries and to address most important riddles: What does matter consist of? What is the structure of proteins that have a fundamental role in life processes? What can we learn from protein structure to improve the treatment of diseases and to design more efficient drugs? But also how does an electronic chip behave under the effect of radiations? How can the heat flow in a large heat exchanger be optimized? The scientific potential of IRIDE is far reaching and justifies the construction of such a large facility in Italy in synergy with the national research institutes and companies and in the framework of the European and international research. It will impact also on R&D work for ILC, FEL, and will be complementarity to other large scale accelerator projects. IRIDE is also intended to be realized in subsequent stages of development depending on the assigned priorities. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1307.7967v1-abstract-full').style.display = 'none'; document.getElementById('1307.7967v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 30 July, 2013; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2013. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">270 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1306.5655">arXiv:1306.5655</a> <span> [<a href="https://arxiv.org/pdf/1306.5655">pdf</a>, <a href="https://arxiv.org/format/1306.5655">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> SuperB Technical Design Report </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=SuperB+Collaboration"> SuperB Collaboration</a>, <a href="/search/physics?searchtype=author&query=Baszczyk%2C+M">M.

The SuperB asymmetric collider, which was to be constructed on the Tor Vergata campus near the INFN Frascati National Laboratory, was designed to operate both at the Upsilon(4S) center-of-mass energy with a luminosity of 10^{36} cm^{-2}s^{-1} and at the tau/charm production threshold with a luminosity of 10^{35} cm^{-2}s^{-1}. This high luminosity, producing a data sample about a factor 100 larger than present B Factories, would allow investigation of new physics effects in rare decays, CP Violation and Lepton Flavour Violation. This document details the detector design presented in the Conceptual Design Report (CDR) in 2007. The R&D and engineering studies performed to arrive at the full detector design are described, and an updated cost estimate is presented. A combination of a more realistic cost estimates and the unavailability of funds due of the global economic climate led to a formal cancelation of the project on Nov 27, 2012. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1306.5655v1-abstract-full').style.display = 'none'; document.getElementById('1306.5655v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 24 June, 2013; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2013. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">495 pages</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> INFN-13-01/PI, LAL 13-01, SLAC-R-1003 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1202.1315">arXiv:1202.1315</a> <span> [<a href="https://arxiv.org/pdf/1202.1315">pdf</a>, <a href="https://arxiv.org/format/1202.1315">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevLett.108.147701">10.1103/PhysRevLett.108.147701 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Widely tunable, non-degenerate three-wave mixing microwave device operating near the quantum limit </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Roch%2C+N">Nicolas Roch</a>, <a href="/search/physics?searchtype=author&query=Flurin%2C+E">Emmanuel Flurin</a>, <a href="/search/physics?searchtype=author&query=Nguyen%2C+F">Fran莽ois Nguyen</a>, <a href="/search/physics?searchtype=author&query=Morfin%2C+P">Pascal Morfin</a>, <a href="/search/physics?searchtype=author&query=Campagne-Ibarcq%2C+P">Philippe Campagne-Ibarcq</a>, <a href="/search/physics?searchtype=author&query=Devoret%2C+M+H">Michel H.

It is based on a new superconducting building-block consisting of a ring of four Josephson junctions shunted by a cross of four linear inductances. The phase configuration of the ring remains unique over a wide range of magnetic fluxes threading the loop. It is thus possible to vary the inductance of the ring with flux while retaining a strong, dissipation-free, and noiseless non-linearity. The device has been operated in amplifier mode and its noise performance has been evaluated by using the noise spectrum emitted by a voltage biased tunnel junction at finite frequency as a test signal. The unprecedented accuracy with which the crossover between zero-point-fluctuations and shot noise has been measured provides an upper-bound for the noise and dissipation intrinsic to the device. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1202.1315v1-abstract-full').style.display = 'none'; document.getElementById('1202.1315v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 February, 2012; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2012. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Accepted for Physical Review Letters.
