Neutron induced nuclear counter effect in Hamamatsu silicon PIN diodes and APDs was measured by irradiating fast neutrons from 252Cf and 241Am-Be sources directly to these devices. It was found that the entire kinetic energy of these fast neutrons may be converted into electron signals in these devices, leading to anomalous signals of up to a few millions electrons in a single isolated readout channel...
In this paper, we report an investigation on the radiation damage effects induced by neutrons in large size crystal scintillator: BGO, CeF3, LYSO:Ce and PWO. The irradiations were carried out by using fast neutrons from one 241Am-Be and two 252Cf sources. The optical and scintillation properties of these samples, including UV excitation and emission spectra, longitudinal transmission, light output,...
