Each digital optical module contains a set of 31 three inch photomultiplier tubes distributed over the surface of a 0.44 m diameter pressure-resistant glass sphere. The module includes also calibration instruments and electronics for power, readout and data acquisition. The power board was developed to supply power to all the elements of the digital optical module. The design of the power board began in 2013, and several prototypes were produced and tested. After an exhaustive validation process in various laboratories within the KM3NeT Collaboration, a mass production batch began, resulting in the construction of over 1200 power boards so far. These boards were integrated in the digital optical modules that have already been produced and deployed, 828 until October 2023. In 2017, an upgrade of the power board, to increase reliability and efficiency, was initiated. After the validation of a pre-production series, a production batch of 800 upgraded boards is currently underway. This paper describes the design, architecture, upgrade, validation, and production of the power board, including the reliability studies and tests conducted to ensure the safe operation at the bottom of the Mediterranean Sea throughout the observatory's lifespan <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2311.14872v1-abstract-full').style.display = 'none'; document.getElementById('2311.14872v1-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 November, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.11310">arXiv:2111.11310</a> <span> [<a href="https://arxiv.org/pdf/2111.11310">pdf</a>, <a href="https://arxiv.org/format/2111.11310">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</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/10.1038/s41586-021-03382-w">10.1038/s41586-021-03382-w <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The data-driven future of high energy density physics </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Hatfield%2C+P+W">Peter W.

These extreme physical systems are strongly non-linear and very difficult to understand theoretically or optimize experimentally. Here, we argue that machine learning models and data-driven methods are in the process of reshaping our exploration of these extreme systems that have hitherto proven far too non-linear for human researchers. From a fundamental perspective, our understanding can be helped by the way in which machine learning models can rapidly discover complex interactions in large data sets. From a practical point of view, the newest generation of extreme physics facilities can perform experiments multiple times a second (as opposed to ~daily), moving away from human-based control towards automatic control based on real-time interpretation of diagnostic data and updates of the physics model. To make the most of these emerging opportunities, we advance proposals for the community in terms of research design, training, best practices, and support for synthetic diagnostics and data analysis. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.11310v1-abstract-full').style.display = 'none'; document.getElementById('2111.11310v1-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> 22 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </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">14 pages, 4 figures.

The main goals of the telescope are the observation of neutrino sources in the Universe and the measurement of the neutrino oscillation parameters with atmospheric neutrinos. Both extraterrestrial and atmospheric neutrinos are detected through the Cherenkov light induced in seawater by charged particles produced in neutrino interactions in the surrounding medium. A relative time synchronization between photomultipliers of the order of 1 ns is needed to guarantee the required angular resolution of the detector. Due to the large detector volumes to be instrumented by KM3NeT, a cost reduction of the different systems is a priority. To this end, the inexpensive Nanobeacon has been designed and developed by the KM3NeT Collaboration to be used for detector time-calibration studies. At present, more than 600 Nanobeacons have been already produced. The characterization of the optical pulse and the wavelength emission profile of the devices are critical for the time calibration. In this paper, the main features of the Nanobeacon design, production and operation, together with the main properties of the light pulse generated are described. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.00223v1-abstract-full').style.display = 'none'; document.getElementById('2111.00223v1-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 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2004.08254">arXiv:2004.08254</a> <span> [<a href="https://arxiv.org/pdf/2004.08254">pdf</a>, <a href="https://arxiv.org/format/2004.08254">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 Methods for Astrophysics">astro-ph.IM</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="Instrumentation and Detectors">physics.ins-det</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/10.1088/1748-0221/15/10/P10005">10.1088/1748-0221/15/10/P10005 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Event reconstruction for KM3NeT/ORCA using convolutional neural networks </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/physics?searchtype=author&query=Albert%2C+A">Arnauld Albert</a>, <a href="/search/physics?searchtype=author&query=Garre%2C+S+A">Sergio Alves Garre</a>, <a href="/search/physics?searchtype=author&query=Aly%2C+Z">Zineb Aly</a>, <a href="/search/physics?searchtype=author&query=Ameli%2C+F">Fabrizio Ameli</a>, <a href="/search/physics?searchtype=author&query=Andre%2C+M">Michel Andre</a>, <a href="/search/physics?searchtype=author&query=Androulakis%2C+G">Giorgos Androulakis</a>, <a href="/search/physics?searchtype=author&query=Anghinolfi%2C+M">Marco Anghinolfi</a>, <a href="/search/physics?searchtype=author&query=Anguita%2C+M">Mancia Anguita</a>, <a href="/search/physics?searchtype=author&query=Anton%2C+G">Gisela Anton</a>, <a href="/search/physics?searchtype=author&query=Ardid%2C+M">Miquel Ardid</a>, <a href="/search/physics?searchtype=author&query=Aublin%2C+J">Julien Aublin</a>, <a href="/search/physics?searchtype=author&query=Bagatelas%2C+C">Christos Bagatelas</a>, <a href="/search/physics?searchtype=author&query=Barbarino%2C+G">Giancarlo Barbarino</a>, <a href="/search/physics?searchtype=author&query=Baret%2C+B">Bruny Baret</a>, <a href="/search/physics?searchtype=author&query=Pree%2C+S+B+d">Suzan Basegmez du Pree</a>, <a href="/search/physics?searchtype=author&query=Bendahman%2C+M">Meriem Bendahman</a>, <a href="/search/physics?searchtype=author&query=Berbee%2C+E">Edward Berbee</a>, <a href="/search/physics?searchtype=author&query=Bertin%2C+V">Vincent Bertin</a>, <a href="/search/physics?searchtype=author&query=Biagi%2C+S">Simone Biagi</a>, <a href="/search/physics?searchtype=author&query=Biagioni%2C+A">Andrea Biagioni</a>, <a href="/search/physics?searchtype=author&query=Bissinger%2C+M">Matthias Bissinger</a>, <a href="/search/physics?searchtype=author&query=Boettcher%2C+M">Markus Boettcher</a>, <a href="/search/physics?searchtype=author&query=Boumaaza%2C+J">Jihad Boumaaza</a>, <a href="/search/physics?searchtype=author&query=Bouta%2C+M">Mohammed Bouta</a> , et al.

The KM3NeT/ORCA water-Cherenkov neutrino detector off the French coast will instrument several megatons of seawater with photosensors. Its main objective is the determination of the neutrino mass ordering. This work aims at demonstrating the general applicability of deep convolutional neural networks to neutrino telescopes, using simulated datasets for the KM3NeT/ORCA detector as an example. To this end, the networks are employed to achieve reconstruction and classification tasks that constitute an alternative to the analysis pipeline presented for KM3NeT/ORCA in the KM3NeT Letter of Intent. They are used to infer event reconstruction estimates for the energy, the direction, and the interaction point of incident neutrinos. The spatial distribution of Cherenkov light generated by charged particles induced in neutrino interactions is classified as shower- or track-like, and the main background processes associated with the detection of atmospheric neutrinos are recognized. Performance comparisons to machine-learning classification and maximum-likelihood reconstruction algorithms previously developed for KM3NeT/ORCA are provided. It is shown that this application of deep convolutional neural networks to simulated datasets for a large-volume neutrino telescope yields competitive reconstruction results and performance improvements with respect to classical approaches. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2004.08254v1-abstract-full').style.display = 'none'; document.getElementById('2004.08254v1-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> 17 April, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> JINST 15 P10005 (2020) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1906.02704">arXiv:1906.02704</a> <span> [<a href="https://arxiv.org/pdf/1906.02704">pdf</a>, <a href="https://arxiv.org/format/1906.02704">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 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/10.1140/epjc/s10052-020-7629-z">10.1140/epjc/s10052-020-7629-z <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Dependence of atmospheric muon flux on seawater depth measured with the first KM3NeT detection units </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/physics?searchtype=author&query=KM3NeT+Collaboration"> KM3NeT Collaboration</a>, <a href="/search/physics?searchtype=author&query=Ageron%2C+M">M.
