Abstract :
We focus on the problem of the spatial localization of energy releasing events (hits) in segmented large-volume HPGe detectors. We present an algorithm for a precise radial coordinate estimation of events occurring at the same time in the same segment. The algorithm was designed bearing in mind that, with up to thousands of parallel channels, it is mandatory to perform the measurements in each channel with the least possible number of input data, while losing no important information and, possibly, operating on line in real time. For the sake of simulation, hits with energy ranging from 60 keV up to 2 MeV are taken into account and electronic noise and signal finite bandwidth effects are considered
