Further study of CdWO4 crystal scintillators as detectors for high sensitivity 2β2β experiments: Scintillation properties and pulse-shape discrimination

Energy resolution, non-proportionality in the scintillation response, α/βα/β ratio, pulse shape for γγ rays and αα particles were studied with CdWO4 crystal scintillators. Some indication for a difference in the emission spectra for γγ rays and αα particles was observed. No dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser, αα particles and γγ ray excitation was observed. Dependence of scintillation pulse shape for γγ quanta and αα particles and pulse-shape discrimination ability on temperature was measured in the range of 0–24 °C.
