RADIATION INDUCED COLOR CENTERS IN A LA DOPED PbWO4 CRYSTAL
نویسندگان
چکیده
This report presents result of a study on radiation induced color center densities in a La doped lead tungstate (PbWO4) crystal. The creation and annihilation constants of radiation induced color centers were determined by using transmittance data measured for a PbWO4 sample before and during 60Co -ray irradiation at a dose rate of 15 rad/hr. Following a model of color center kinetics, these constants were used to calculate color center densities under irradiations at 100 rad/hr. The result was found to be in a good agreement with experimental data, indicating that the behavior of PbWO4 crystals under irradiation can be predicted according to this model. Sumbitted to Nucl.

متن کاملPulse-shape discrimination with PbWO4 crystal scintillators
The light output, α/β ratio, and pulse shape have been investigated at −25◦ C with PbWO4 crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast 0.01 − 0.06 μs and middle 0.1 − 0.5 μs components of scintillation decay were observed for all the samples. Slow components of scintillation signal with the decay times 1− 3 μs and 13− 28 μs with the total intensity up to ≈ 50% have b...

A PbWO4 crystal produced for the electromagnetic calorimeter of the CMS experiment at the LHC was cut into three equal-length sections. The central one was irradiated with 290 MeV/c positive pions up to a fluence of (5.67± 0.46)× 10 cm, while the other two were exposed to a 24 GeV/c proton fluence of (1.17 ± 0.11) × 10 cm. The damage recovery in these crystals, stored in the dark at room temper...
