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).
