The TMR network project "Development of gamma-ray tracking detectors"

The next generation of 4 pi arrays for high-precision gamma -ray spectrosco py will involve gamma -ray tracking detectors. They consist of high-fold se gmented Ge detectors and a front-end electronics, based on new digital sign al processing techniques, which allows to extract energy, timing and spatia l information for a gamma -ray by pulse shape analysis of the Ge detector s ignals. Utilizing the information on the positions of the interaction point s and the energies released at each point the tracks of the gamma -rays in a Ge shell can be reconstructed in three dimensions.
