Abstract The Compact Muon Solenoid collaboration is designing a new high-granularity endcap calorimeter, HGCAL, to be installed later this decade. As part of development work, prototype system was built, with an electromagnetic section consisting 14 double-sided structures, providing 28 sampling layers. Each layer has hexagonal module, where multipad large-area silicon sensor glued between electronics circuit board and metal baseplate. pads approximately 1.1 cm 2 are wire-bonded the readout...
Abstract The upgrade of the CMS experiment for high luminosity operation LHC comprises replacement current endcap calorimeter by a granularity sampling (HGCAL). electromagnetic section HGCAL is based on silicon sensors interspersed between lead and copper (or tungsten) absorbers. hadronic uses layers stainless steel as an absorbing medium active in regions radiation exposure, scintillator tiles directly read out photomultipliers remaining regions. As part development detector its readout...
Abstract This paper describes the experience with calibration, reconstruction and evaluation of timing capabilities CMS HGCAL prototype in beam tests 2018. The calibration procedure includes multiple steps corrections ranging from tens nanoseconds to a few hundred picoseconds. performance is studied using signals positron particles energies between 20 GeV 300 GeV. as function particle energy against an external reference well standalone by comparing two different halves prototype. resolution...
Abstract The CMS experiment at the CERN LHC will be upgraded to accommodate 5-fold increase in instantaneous luminosity expected High-Luminosity (HL-LHC) [1]. Concomitant with this an number of interactions each bunch crossing and a significant total ionising dose fluence. One part upgrade is replacement current endcap calorimeters high granularity sampling calorimeter equipped silicon sensors, designed manage collision rates [2]. As development calorimeter, series beam tests have been...
As part of its HL-LHC upgrade program, the CMS collaboration is replacing existing endcap calorimeters with a high-granularity calorimeter (CE). The new sampling unprecedented transverse and longitudinal readout for both electromagnetic hadronic compartments. Due to compactness, intrinsic time resolution, radiation hardness, silicon has been chosen as active material regions exposed higher levels. sensors are fabricated 20 cm (8") wide hexagonal wafers segmented into several hundred pads...
