Overview of PbWO4 Calorimeter in CMS
No full textThe status is given of the Lead Tungstate electromagnetic crystal calorimeter for the CMS detector at LHC. This includes some basic information about the engineering design of the calorimeter and the readout system, latest results on Lead Tungstate crystals and photodetector development, with particular attention to radiation hardeness issues, and results from test measurements in particle beams
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
The CMS ECAL Project - Overview and Status Report
No full textAn overview is given of the Lead Tungstate ( PbWO4) electromagnetic crystal calorimeter for the CMS detector at the Large Hadron Collider ( LHC) at CERN in Geneva. This includes a description of the engineering design, the development of the calorimeter components, the read-out system and results obtained in particle beams
Measurements of Lead Tungstate Crystals Behaviour Under Irradiation for the CMS Electromagnetic Calorimeter at the LHC
No full textLead Tungstate crystals will be used as calorimetric medium in high energy physics at CERN, in a particularly hostile radiation environment. Methods of testing their behaviour under irradiation are discussed here and are illustrated by some R&D results
