The CMS Lead Tungstate Electromagnetic Calorimeter
The CERN LHC will open a new regime in the exploration of fundamental interactions. Of central importance to these studies will be the precise measurement of high energy electrons and photons. The CMS experiment therefore incorporates a high resolution electromagnetic calorimeter comprising 76000 lead tungstate crystals, covering almost 4pi, and capable of operating reliably for ten years in a ...
متن کاملMeasurements of Lead Tungstate crystals behaviour under irradiation for the CMS electromagnetic calorimeter at the LHC
Lead 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. Presented at 5th European Conference on Radiation and its Effects on Components and Systems, (Fontevraud, France, September 1999) For the CMS C...
متن کاملThe CMS electromagnetic calorimeter
From 2007 the new CERN proton proton collider will start collisions that could open new perspectives in the fields of high energy particle physics. The CMS experiment at the LHC is in advanced construction phase. In particular new physics could be discovered thanks to the CMS precise electromagnetic calorimeter (ECAL) made of about 75000 scintillating PbWO 4 crystals. A description of the ECAL ...
متن کاملThe CMS Electromagnetic Calorimeter Readout
CMS is a general-purpose detector designed for use in the large hadron collider (LHC) at CERN. The electromagnetic calorimeter will play an important role in electron and photon energy measurements. The benchmark process to evaluate and optimize its performance is H −→ γγ in the intermediate mass range (90 < mH < 150 GeV). For this purpose, each element of the readout chain has to be optimized....
متن کاملBeam tests of lead tungstate crystal matrices and a silicon strip preshower detector for the CMS electromagnetic calorimeter
Further tests of lead tungstate crystal matrices made in high energy electron beams in 1996, using new crystals, new APDs and an improved test setup confirm that an energy resolution of better than 0.6% at 100 GeV can be obtained when the longitudinal uniformity of the struck crystal is adequate. Light loss measurements under low dose irradiation are reported. It is shown that there is no loss ...
