Pulse-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...

Pulse Shape Discrimination with The Neutron Walls at NCSL

The National Superconducting Cyclotron Laboratory at Michigan State University has recently completed the Coupled Cyclotron Upgrade. The new facility will concentrate on the study of rare isotopes produced in fragmentation reactions. Neutron-rich unstable isotopes can be investigated via break-up reactions. The resulting neutrons will be detected in two walls of position sensitive detectors. Ea...

Pulse-shape discrimination of La halide scintillators

The bright scintillators LaCl3:Ce and LaBr3:Ce were tested for a–g pulse-shape discrimination (PSD). PSD is demonstrated for LaCl3:Ce but not for LaBr3:Ce: r 2005 Elsevier B.V. All rights reserved.
