A High-Granularity Timing Detector (HGTD) for the Phase-II upgrade of the ATLAS detector / Mazza, Simone Michele (Santa Cruz Institute for Particle Physics, University of California Santa Cruz)
The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L$ = 7.5\times 10^{34} $cm$^{-1} $s$^{-1}$ will have a severe impact on the ATLAS detector performance. [...]
