The CMS Electromagnetic Calorimeter - Overview and Status Report
No full textAn overview status is given of the Lead Tungstate electromagnetic calorimeter which is being developped for the CMS detector at LHC. This includes the development status of PbWO4 crystals, the mechanical design of the calorimeter, the read-out and a brief look into results from test measurements in particle beams
Response evolution of the CMS ECAL and R&D studies for electromagnetic calorimetry at the High-Luminosity LHC
No full textWhile the CMS experiment is currently harvesting LHC collision data at CERN, the performance of its electromagnetic calorimeter (ECAL) is being constantly monitored, and work has started to assess the need for changes to the detector to ensure an adequate performance for High-Luminosity LHC (HL-LHC) running, which is planned for 2022 and beyond. In this paper, results from CMS running, beam tests and laboratory measurements are combined to anticipate the detector performance evolution at the HL-LHC. Further, various R&D studies are illustrated, that will provide a useful choice for electromagnetic calorimetry at the HL-LHC.While the CMS experiment is currently harvesting LHC collision data at CERN, the performance of its electromagnetic calorimeter (ECAL) is being constantly monitored, and work has started to assess the need for changes to the detector to ensure an adequate performance for High-Luminosity LHC (HL-LHC) running, which is planned for 2022 and beyond.

Crystals for high-energy calorimeters in extreme environments
No full textScintillating crystals are used for calorimetry in several high-energy physics experiments. For many of them, performance has to be ensured in very difficult operating conditions, like a high radiation environment and large particle fluxes, which place constraints on response and readout time. An overview is presented of the knowledge reached up to date, and of the newest achievements in the field, with particular attention given to the performance of Lead Tungstate crystals exposed to large particle fluxes
