| Abstract | Calorimetry at the High Luminosity LHC (HL-LHC) faces two enormous challenges, particularly in the forward direction radiation tolerance and unprecedented in-time event pileup. To meet these challenges, the CMS experiment has decided to construct a High Granularity Calorimeter (HGCAL), featuring an unprecedented transverse and longitudinal segmentation in a collider detector, both for electromagnetic and hadronic compartments. This will enable the optimal utilization of the Particle Flow Algorithms, with which the fine structure of showers can be measured and used to enhance particle identification, energy resolution and pileup rejection. The majority of the HGCAL will be based on robust and cost-effective hexagonal silicon sensors with 1cm^2 or 0.5cm^2 hexagonal cell size, with the final 5 interaction lengths of the hadronic compartment being based on highly segmented plastic scintillator with SiPM readout. Here, we present an overview of the HGCAL project, including the motivation, engineering design, readout/trigger concept and simulated performance. |
