In this paper, we present results of a study on Sb doping in lead tungstate crystals. The crystal growth by modified Bridgman method is described. The segregation coefficient of Sb ions in lead tungstate crystals was determined. The scintillation emission and longitudinal transmittance spectra, light output, decay kinetics and radiation damage were measured. It is found that Sb doping alone is ...

Lead Tungstate crystals for the CMS detector at LHC have to withstand severe levels of radiation. Presented here are measurement techniques and results on crystal behaviour under gamma irradiation from tests at ETH/PSI in conditions similar to what is expected during operation of the CMS electromagnetic calorimeter. Presented at International Workshop on Lead Tungstate crystals, Rome, Italy, Oc...
