Improvement of Several Properties of Lead Tunstate Crystals with Different Doping Ions
A very good radiation resistance of Lead Tungstate crystals is mandatory for their use in the high precision electromagnetic calorimeter of the CMS experiment at LHC. Since the beginning of 1996 we have organised systematic investigations of the parameters influencing the radiation hardness of this crystal. Two classes of parameters have been particularly studied, the first one related to the c...
متن کاملA study on SB doping in lead tungstate crystals
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 ...

متن کاملEvaluation of mass-produced lead tungstate crystals
Because of broad interest in high-energy and nuclear physics community, mass production capacities of lead tungstate (PWO) crystals have been established. The optical and scintillation properties of PWO crystals, 20 each from two major vendors, were evaluated. The transmittance, emission and excitation spectrum, light output, decay kinetics and light response uniformity, as well as their degrad...
