Abstract :
A program for simulating pulse shapes of HPGe detectors has been developed taking into account the closed-ended geometry as well as multiple interactions of γ-rays. Good agreement between simulated and experimentally determined pulse shapes is achieved. From a detailed investigation of risetime distributions a method to determine the radial coordinate of the first point of interaction has been substantiated. For a large Ge detector with 70 mm diameter a radial resolution of 4 to 8 mm has been obtained. This method, combined with segmentation of the detector, reduces the Doppler broadening of γ-lines significantly.
