Figure 8
Energy resolution (FWHM) at 59.5 keV versus the bias voltage at room temperature for the CZT detectors. The spectra were measured by using the digital slow PSHA with ST = 9 µs (optimal ST value). The same low-rate results were obtained by using an analog Gaussian shaping amplifier (model 672, Ortec, USA) with a shaping time constant of 1 µs and a commercial multichannel analyser (MCA 8000A, Amptek, USA).
