At the High Luminosity LHC, the CMS detector will be exposed to large pile-up conditions and large radiation dose. To cope with the challenges, the whole endcap calorimeter system will be replaced with the High Granularity Calorimeter containing 52 longitudinal sampling layers made of silicon sensors in the high radiation area and scintillators read out by SiPMs in the low radiation area. A...
The existing CMS endcap calorimeters - electromagnetic and hadronic - will be replaced by a sampling calorimeter - the High Granularity Calorimeter (HGCAL) - featuring unprecedented transverse and longitudinal readout and triggering granularity. This will facilitate particle-flow reconstruction in the harsh radiation and pileup environment of HL-LHC collisions. Exploiting the high granularity...
The CMS High Granularity Calorimeter will replace the existing endcap calorimeters for the High-Luminosity phase of LHC. It will be based on hexagonal silicon pad sensors (in the highest radiation regions) and scintillator tiles with on-tile SiPM readout (in the lower radiation regions). Prototypes of both detector types have been made and tested extensively in laboratories and beams, with...
The high luminosity (HL) LHC will pose significant detector challenges for radiation tolerance and event pileup, especially for forward calorimetry, and this will provide a benchmark for future hadron colliders. The CMS experiment has chosen a novel high granularity calorimeter (HGCAL) for the forward region as part of its planned Phase 2 upgrade for the HL-LHC. Based largely on silicon...
