In the latter field, today the problem is not just limited to Single Event Effects (SEE) as used in avionics, but is more and more observed at ground level. Galactic cosmic muons, coming from the interaction of primary cosmic rays in the Earth's atmosphere, represent the most numerous species at ground level. In this work, we used the Monte Carlo code FLUKA to assess the atmospheric and terrestrial neutron and muon differential fluxes at various altitudes and specific examples such as the geographic coordinates corresponding to New York City and Vancouver. In this context, particle energy spectra were compared with references available in literature, calculation results obtained by both the QARM and EXPACS codes, as well as recently performed measurements. In addition, the zenith angular distribution, at ground level, was assessed for both neutrons and muons and compared with available references. Differential particle fluxes assessed for Vancouver were used as a primary source to simulate a muon detector currently taking data at TRIUMF to evaluate the passing and stopping terrestrial muon rate under different conditions. Finally, simulations were compared with the experimental measurements made at TRIUMF. Results show an excellent agreement between the FLUKA simulations and both references and the experimental measurements made at TRIUMF.</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Infantino, Angelo</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Blackmore, Ewart W</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Brugger, Markus</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Al铆a, Rub茅n Garc铆a</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Stukel, Matthew</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Trinczek, Michael</dc:creator> <pubDate>Tue, 13 Jun 2017 04:17:28 GMT</pubDate> <guid>https://cds.cern.ch/record/2268714</guid> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> <item> <title>SEL Cross Section Energy Dependence Impact on the High Energy Accelerator Failure Rate</title> <link>https://cds.cern.ch/record/2056669</link> <description>We use a single event latchup (SEL) model calibrated to heavy ion (HI) and proton data below 230聽MeV to extrapolate the proton cross section to larger energies and evaluate the impact of the potential cross section increase with energy on the SEL rate in different environments. We show that in the case of devices with a large LET onset for HI and a certain amount of tungsten near the sensitive volume (SV), the calculated failure rates for energetic environments based on monoenergetic test data can significantly underestimate the real value. In addition, we show through measurements using a 480 MeV beam and an inspection of the device鈥檚 architecture that the model was successful in estimating the SEL cross section and tungsten volume per cell.</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Garc铆a Al铆a, Rub茅n</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Blackmore, Ewart W</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Brugger, Markus</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Danzeca, Salvatore</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Ferlet-Cavrois, V茅ronique</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Gaillard, R茅mi</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Mekki, Julien</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Poivey, Christian</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">R酶ed, Ketil</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Saign茅, Fr茅d茅ric</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Spiezia, Giovanni</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Trinczek, Michael</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Uznanski, Slawosz</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Wrobel, Fr茅d茅ric</dc:creator> <pubDate>Fri, 02 Oct 2015 04:01:23 GMT</pubDate> <guid>https://cds.cern.ch/record/2056669</guid> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> <item> <title>Operating Experience with Meson Production Targets at TRIUMF</title> <link>https://cds.cern.ch/record/928379</link> <description>High power targets are now required for operation at beam powers in excess of 1 MW for spallation neutron sources and neutrino factories. TRIUMF has been operating beryllium and graphite meson production targets for many years. Although the proton beam power of 100 kW at 500 MeV is lower, the beam densities and fluences are higher than most operating solid targets as other accelerators use rotating targets or larger beam spots. The beam size on the TRIUMF targets is maintained at 0.15 cm2 and this beam density leads to proton fluences of 1&amp;#183;1023</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Blackmore, Ewart W</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Dowling, Alisa</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Ruegg, Roman</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Stenning, Mark C</dc:creator> <pubDate>Thu, 09 Feb 2006 03:21:26 GMT</pubDate> <guid>https://cds.cern.ch/record/928379</guid> <media:content xmlns:media="http://search.yahoo.com/mrss/" url="https://accelconf.web.cern.ch/p05/PAPERS/RPPE026.PDF"/> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> <item> <title>Design Concept for AGS Injection Kicker Upgrade to 2 GeV</title> <link>https://cds.cern.ch/record/927279</link> <description>The present AGS injection kickers at A5 location were designed for 1.5 GeV proton injection. Recent high intensity runs have pushed the transfer kinetic energy to 1.94 GeV, but with an imperfect matching in transverse phase space. Space charge forces result in both fast and slow beam size growth and beam loss as the size exceeds the AGS aperture. A proposed increase in the AGS injection energy to 2 GeV with adequate kick strength would greatly reduce the beam losses making it possible to increase the intensity from 70 TP (70 * 1012</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Dale Wait, Gary</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Ahrens, Leif</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Armenta, Roberto</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Barnes, Michael J</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Blackmore, Ewart W</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Gardner, Chris J</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Hadary, Ori</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Zhang, Wu</dc:creator> <pubDate>Tue, 07 Feb 2006 05:57:57 GMT</pubDate> <guid>https://cds.cern.ch/record/927279</guid> <media:content xmlns:media="http://search.yahoo.com/mrss/" url="https://accelconf.web.cern.ch/p05/PAPERS/MPPT014.PDF"/> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> <item> <title>The PS complex as proton pre-injector for the LHC: design and implementation report</title> <link>https://cds.cern.ch/record/449242</link> <description/> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">CERN.
