Abstract: (IOP)
Calorimetry at the High-Luminosity LHC (HL-LHC) faces many challenges, particularly in theforward direction, such as radiation tolerance and large in-time event pileup. To meet thesechallenges, the CMS Collaboration is preparing to replace its current endcap calorimeters for theHL-LHC era with a High-Granularity Calorimeter (HGCAL), featuring an unprecedented transverse andlongitudinal segmentation, for both the electromagnetic and hadronic sectors, with 5D information(space-time-energy) read out. The proposed design uses silicon sensors for the electromagneticsection and high-irradiation regions of the hadronic section, while in the low-irradiation regionsof the hadronic section plastic scintillator tiles equipped with on-tile silicon photomultipliers(SiPMs) are used. The full HGCAL will have approximately 6 million silicon sensor channels andabout 240 thousand channels of scintillator tiles. This will facilitate particle-flow-typecalorimetry, where the fine structure of showers can be measured and used to enhance particleidentification, energy resolution and pileup rejection.- Front-end electronics for detector readout
