Ce:YAP — A scintillating crystal with high light yield, fast decay and emission wavelength of 360 nm suitable for γ-ray detection Ce YAP Scintillator Crystal Ce:YAP exhibits a good linearity of the scintillation response for 𝛾-quanta with energy down to a few keV and a high energy resolution, which is favorable for precision spectrometry in X-ray range. Due to relatively light ions building the YAP matrix, the dependence of the attenuation factor on energy is linear and enables very good energy resolution in the soft energy range of 𝛾 quanta. An excellent energy resolution of 5.7% for γ-rays from a 137Cs source (one of the best measured with scintillation detectors) and a very good time resolution of 160 ps for 60Co γ-rays with a threshold of 1 MeV. Ce YAP Scintillator Crystal Ce: YAP is a high temperature scintillating crystal with excellent properties. It has attracted more abroad because of its high light yield, fast decay time (about 27 ns) and neutr...
