Lyso scintillator rise fall time
WebJan 7, 2024 · However, it plays a dominant role in reproducing the shape and features (rise time, amplitude) of the signal produced by the detection of a gamma ray. In such a way, it mostly determines the threshold for the best time resolution. WebLYSO (Ce) has a light yield three times greater than the BGO, and CsI (Tl) light yield is twice than LYSO (Ce). The analysis of the signal waveform or the trend of the charge vs integration time leads to the measurement of the time characteristics of the scintillator. 137 Cs energy spectra.
