Light yield non-proportionality of undoped YAP scintillator
2009 (English)Article in journal (Refereed) Published
Scintillation properties of undoped YAP crystal were studied. The emission spectra show a very intense light component at 360 nm. Analysis of the light pulse shape resulted in five components, four of them, with time constants of 38+/-2 ns, 92+/-3 ns, 7.5+/-0.5 mu s and 24+/-3 mu s, representing high light intensity. The light yield was found to be temperature dependent, N-ph=3090+/-130 ph/MeV at liquid nitrogen temperature and N-ph=1440+/-60 ph/MeV at room temperature. Also the light yield non-proportionality shows temperature dependence and is more pronounced at room temperature.
