Monitoring Light Source for Cms Lead Tungstate Crystal Calorimeter at Lhc
Light monitoring will serve as an intercalibration for compact muon solenoid (CMS) lead tungstate crystals in situ at the large hadronic collider, which is crucial for maintaining crystal calorimeter’s subpercent constant term in the energy resolution. This paper presents the design of the CMS electromagnetic calorimeter monitoring light source and high-level distribution system. The correlatio...
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 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 کاملThe CMS crystal calorimeter for the LHC
The CMS crystal calorimeter, comprising about 80,000 scintillating lead tungstate crystals read out by avalanche photodiodes (in the barrel) and vacuum phototriodes (in the endcap), is designed to give excellent energy resolution in the demanding LHC environment. It is now entering the construction phase. A status report on the project is presented, including recent results from test beam verif...
متن کاملDiode laser--pumped solid-state lasers.
Diode laser-pumped solid-state lasers are efficient, compact, all solid-state sources of coherent optical radiation. Major advances in solid-state laser technology have historically been preceded by advances in pumping technology. The helical flash lamps used to pump early ruby lasers were superseded by the linear flash lamp and arc lamp now used to pump neodymium-doped yttrium-aluminum-garnet ...
