Neutron/gamma discrimination enhancement: plastic scintillators high dose irradiation and recovery time

Time Correlated Measurements Using Plastic Scintillators with Neutron-Photon Pulse Shape Discrimination

Temperature dependence of plastic scintillators

Plastic scintillator detectors have been studied as dosimeters, since they provide a cost-effective alternative to conventional ionization chambers. On the other hand, several articles have reported undesired response dependencies on beam energy and temperature, which enhances the necessity to determine appropriate correction factors. In this work, we studied the light yield temperature depende...

Monte Carlo calculations of the absorbed dose and energy dependence of plastic scintillators.

Detector systems using plastic scintillators can provide instantaneous measurements with high spatial resolution in many applications including small field and high dose gradient field applications. Energy independence and water equivalence are important dosimetric properties that determine whether a detector will be useful in a clinical setting. Using Monte Carlo simulations, we calculated the...

Ultra-Fast Timing with Plastic Scintillators

As precursor to HISPEC, the upcoming PreSPEC campaign incorporates the commissioning of the first version of the LYCCA (Lund-York-Cologne-CAlorimeter) detector system called LYCCA-0. The LYCCA detector is a Time-of-Flight (ToF), ∆E, E set-up designed to unambigiously identify nuclear reaction products by their mass A, and charge Z . For this to be possible up to masses around A = 100, the total...

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...
