These studies are performed using data collected during the first and the second periods of LHC operation and are compared with Monte Carlo simulations. The performance of the TRT\, operating with different gas mixtures (Xenon-based and Argon-based) and for high track m ultiplicities is presented. These studies show that the tracking performan ce of the TRT with these two gas mixtures is similar and that the detector still provides a significant contribution to the particle momentum measur ement of the overall Inner Detector of the ATLAS experiment up to very hig h track densities and detector occupancies.\n\nhttps://indico.particle.mep hi.ru/event/4/contributions/786/ LOCATION:Milan Hotel Vivaldi-Boccerini URL:https://indico.particle.mephi.ru/event/4/contributions/786/ END:VEVENT BEGIN:VEVENT SUMMARY:Some results of test beam studies of Transition Radiation Detector prototype at CERN.

Due to these leaks\, primary Xenon based gas mixture was replaced with Argon based mixture in various parts. Test-beam studies with a dedicated Transition Radiation Detector (TRD) prototype w ere carried out in 2015 in order to understand transition radiation perfor mance with mixtures based on Ar and Kr. We present and discuss the results of these test-beam studies with different active gas compositions.\n\nhtt ps://indico.particle.mephi.ru/event/4/contributions/741/ LOCATION:Milan Hotel Vivaldi-Boccerini URL:https://indico.particle.mephi.ru/event/4/contributions/741/ END:VEVENT BEGIN:VEVENT SUMMARY:Effect of graphen monolayer on the transition radiation yield of the radiators based on polyethylene foils DTSTART;VALUE=DATE-TIME:20161011T124500Z DTEND;VALUE=DATE-TIME:20161011T130000Z DTSTAMP;VALUE=DATE-TIME:20260814T160227Z UID:indico-contribution-102-683@cern.ch DESCRIPTION:Speakers: Alexey Tishchenko (MEPhI)\nMeasurements of the Trans ition Radiation (TR) yield from polyethylene foils covered with one monola yer of graphene will be presented.

The ICARUS Collaboration concluded a very successful\, lo ng duration run with the T600 detector at the LNGS underground laboratory\ , taking data both with the CNGS neutrino beam and with cosmic rays. It pe rformed a sensitive search for anomalous νe appearance as suggested by LS ND signal and experimental neutrino anomalies at reactors and with the cal ibration sources in solar neutrino searches. The analysis of the νμCC ev ents collected with the CNGS beam is progressing\, in view of the comparis on with the expected flux in absence of anomalies. The collected cosmic ra y triggers are being analyzed too aiming at studying the atmospheric neutr ino interactions.\nThe detector is being overhauled at CERN and will be re ady to be installed at Fermilab by the end of this year to investigate wit hin the SBN project the presence of sterile neutrino\, exploring in three years of data taking the νμ to νe appearance signal with 5 sigma sensit ivity in the parameter region indicated by the LSND experiment and measuri ng the νμ disappearance with a sensitivity exceeding an order of magnitu de the present experimental limits.\n\nhttps://indico.particle.mephi.ru/ev ent/4/contributions/544/ LOCATION:Milan Hotel Vivaldi-Boccerini URL:https://indico.particle.mephi.ru/event/4/contributions/544/ END:VEVENT BEGIN:VEVENT SUMMARY:Detector for the ultrahigh energy cosmic rays composition study in Antarctica DTSTART;VALUE=DATE-TIME:20161011T131500Z DTEND;VALUE=DATE-TIME:20161011T133000Z DTSTAMP;VALUE=DATE-TIME:20260814T160227Z UID:indico-contribution-102-514@cern.ch DESCRIPTION:Speakers: Dmitry Chernov (Moscow State University\, Skobeltsyn Institute of Nuclear Physics)\nThe main aim of the Sphere-Antarctic proje ct is connected to the fundamental problems of the cosmic ray (CR) physics and general astrophysics — the determination of the energy and mass com position of cosmic ray particles of ultra high and extremely high energies $10^{18}-10^{20}$eV. In the energy region above $6\\cdot10^{19}$eV modern experiments (Telescope Array and Pierre Auger Observatory) observed aniso tropy and the clustering of arrival directions of cosmic rays in some area s. The scientific importance of this problem stems from the lack of genera lly accepted acceleration mechanism of the CR particles above $3\\cdot10^{ 18}$eV\, the unknown nature of the sources of such particles\, the inconsi stencies of the results of major experiments in the part of the mass of CR composition and the discrepancy of experimental and model data. Scientifi c novelty f this project is in the methodology registration of the extensi ve air showers over a large area $\\sim$600 km$^2$ from altitude 30 km\, t hat allows to measure the two optical components of the shower Vavilov-Che renkov radiation and fluorescence light by the same SiPM sensitive element s of the detector simultaneously.\n\nhttps://indico.particle.mephi.ru/even t/4/contributions/514/ LOCATION:Milan Hotel Vivaldi-Boccerini URL:https://indico.particle.mephi.ru/event/4/contributions/514/ END:VEVENT END:VCALENDAR
