LHC/HL-LHC 3
- Yuji Goto (RIKEN (JP))
Calorimetry at the HL-LHC faces two enormous challenges, particularly in the forward direction: radiation tolerance and unprecedented in-time event pileup. Therefore, the CMS Collaboration is preparing to replace its current endcap calorimeters for the HL-LHC era with a high-granularity calorimeter (HGCAL), featuring a previously unrealized transverse and longitudinal segmentation, with 5D...
The endcap calorimeters of CMS will be upgraded a single High Granularity Calorimeter (HGCAL) for the HL-LHC, including both silicon sensors and scintillator tiles with on-tile SiPMs as active elements. Both. The readout of the active elements is performed by an ASIC (HGCROC in 130nm CMOS technology) that measures the amplitude and arrival time of the signals. The amplitude is measured over a...
In preparation for the High-Luminosity era of the LHC, the CMS experiment will replace the existing calorimeter endcaps with a novel device - the High Granularity Calorimeter (HGCAL), having around six million readout channels. The back-end readout system is based on a common CMS-wide development: ATCA boards called "Serenity", featuring optical inputs and FPGA-based processing. The...
The High Granularity Calorimeter (HGCAL) being prepared by the CMS Collaboration for the Phase 2 of the LHC features previously unrealized transverse and longitudinal fine-grained readout of both the electromagnetic and hadronic compartments. The high granularity of the calorimeter, associated with measurements of energy and time of arrival, provides unique inputs for advanced reconstruction...
