Determination of fano factor and pre-amplifier noise from the measurement of energy resolution of a HPGe detector
Samat, S. B1, Priharti, W2.
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 FWHM2
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) × 10−1 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.
