Abstract:
To fully characterize the front dead layer (DL) of an HPGe detector at low photon energy range, its intrinsic efficiency curve was measured using a (241)Am radioactive source in 10-60 keV energy range. A comparison between experimental efficiency and MCNPX results showed that the DL value of 0.4 μm initially quoted by the manufacturer has to be changed to 7.5 μm to reproduce measurements.
