Axes determination for segmented true-coaxial HPGe detectors
arXiv:1112.5291 · doi:10.1140/epjc/s10052-012-1950-0
Abstract
A fast method to determine the crystallographic axes of segmented true-coaxial high-purity germanium detectors is presented. It is based on the analysis of segment-occupancy patterns obtained by irradiation with radioactive sources. The measured patterns are compared to predictions for different axes orientations. The predictions require a simulation of the trajectories of the charge carriers taking the transverse anisotropy of their drift into account.
