Scintillation characteristics of doped PbWO4 crystals

Emission spectra, longitudinal transmission and light output for the Sb-dop ed and Y-doped PbWO4 crystals are presented. Scintillation decay kinetics h as been measured by using gate integration and the single photon counting m ethod with blue and green filters. Radiation hardness has also been measure d by using Co-60 gamma -ray irradiation under different dose rates and diff erent dose rate profiles. The light yield and radiation hardness of the Sb- doped and Y-doped PbWO4 crystals are improved as compared to the undoped cr ystals and are suitable for the requirements of compact muon solenoid.
