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

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