Mass production of PWO crystals for electromagnetic calorimetry: peculiarities and prospects

摘要

This paper is devoted to mass production of the most popular now scintillation material in high energy physics. Among recently developed scintillation materials the lead tungstate (PbWO{sub}4, PWO) already found application in electromagnetic calorimetry in experiments of CMS and ALICE collaborations at LHC. The status of the crystal production, peculiarities of the crystal machining and properties certification, distributions of scintillation parameters as well as long term stability of crystal scintillation properties will be discussed.
