Abstract

A HPGe detector and γ-ray multinuclide standard solution were used to get several data pairs of photon energy E and detector's energy resolution FWHM. A series of graph of FWHM<sup>2</sup> versus E was plotted to determine the detector's Fano factor and pre-amplifier noise, which yielded the mean values of 0.123±0.003 and (7.448±0.011) × 10<sup>-1</sup> keV, respectively. The Fano factor value agrees within 95% confident interval with the mostly quoted value of 0.13 for semiconductor detectors. The obtained preamplifier noise is in agreement with typical manufacturer's specification.
