Response of CdWO4 crystal scintillator for few MeV ions and low energy electrons

The response of a CdWO4 crystal scintillator to protons, α particles, Li, C, O and Ti ions with energies in the range 1-10 MeV was measured. The non-proportionality of CdWO4 for low energy electrons (4-110 keV) was studied with the Compton Coincidence Technique. The energy dependence of the quenching factors for ions and the relative light yield for low energy electrons was calculated using a semi-empirical approach. Pulse-shape discrimination ability between γ quanta, protons, α particles and ions was investigated.
