title: Calculation of the volume of an HPGe crystal.
abstract: An important characteristic of a high-purity germanium detector for gamma spectrometry is the volume of the crystal, which relates to the detection efficiency and to the measured background level. The crystal dimensions provided by the detector manufacturer were used to calculate the crystal volume. The calculation method accounts for the various sub-volumes of the crystal, in particular the contact hole in the back face and the rounding of the 90° right edge in the front face. The calculation was corroborated using the INVENTOR(®) 3D software. The crystal volume was calculated to be 419.7 cm(3) compared with the 413 cm(3) stated by the manufacturer.
