The TMR network project “Development of Gamma-Ray Tracking Detectors” — •R.M. Lieder — Institut für Kernphysik, Forschungszentrum Jülich, D-52425 Jülich

The next generation of 4 π arrays for high-precision γ-ray spectroscopy will involve γ-ray tracking detectors. They consist of high-fold segmented Ge detectors and a front-end electronics, based on new digital signal processing techniques, which allows to extract energy, timing and spatial information for a γ-ray by pulse shape analysis of the Ge detector signals. Utilizing the segmentation and the pulse shape analysis, the track of a γ-ray in a Ge detector can be reconstructed in three dimensions. This development aims at Ge detector arrays of unprecedented qualities to become available. Specific objectives include:
(1) development of segmented Ge detectors
(2) simulations of detectors and detector arrays
(3) development of front-end electronics
(4) development of pulse-shape analysis software
(5) development of data-analysis software
The development is carried out in the framework of a TMR network project by British, Danish, French, German, Italian and Swedish groups. The project started two years ago and a status report of the development will be given. (The work is financially supported by the EU under the TMR network contract no. ERBFMRXCT970123).
