Abstract :
CsI(Tl), CsI(Na), and YAP light yield nonproportionality has been characterized using the Compton Coincidence Technique. Measured electron responses were used to analytically calculate photon responses of scintillators studied. Results from electron response measurement and photon response calculation were then compared with previously reported results. While the CsI(Na) electron response was observed to have the largest deviation from proportionality (about 40%), YAP was observed to have a nearly proportional response. CsI(Tl) and CsI(Na) calculated photon responses are generally in agreement to within 1% with measured photon responses for photon energies above 60 keV. Below 60 keV, deviations up to 5% were observed in the calculated responses
