Pulse-shape discrimination with PbWO4 crystal scintillators
نویسنده
چکیده
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 been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between α particles and γ quanta with PbWO4 (Mo doped) crystal scintillators.

Energy resolution, light yield, non-proportionality in the scintillation response, α/β ratio, pulse shape for γ rays and α particles were studied with CdWO4 crystal scintillators. Some indication for a difference in the emission spectra for γ rays and α particles was observed. No dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser, α particles and γ ray excitation was o...
