Pulse-shape discrimination with PbWO${}_4$ crystal scintillators

Abstract

The light output, $\alpha /\beta$ ratio, and pulse shape have been investigated at $-25^{\circ }$ C with PbWO${}_4$ crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast $0.01-0.06\mu$s and middle $0.1-0.5\mu$s components of scintillation decay were observed for all the samples. Slow components of scintillation signal with the decay times $1-3\mu$s and $13-28\mu$s with the total intensity up to $\approx 50$ have been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between $\alpha$ particles and $\gamma$ quanta with PbWO${}_4$ (Mo doped) crystal scintillators.
