The Group for the development of neutron and gamma detectors in the Central
Institute of Engineering, Electronics and Analytics (ZEA-2) at
Forschungszentrum Juelich (FZJ) has developed, in collaboration with European
institutes, an Anger Camera prototype for improving the impact point
reconstruction of neutron tracks. The detector is a chamber filled with
3He+CF4 gas for neutron capture and subsequent production of a tritium and
a proton. The energy deposition by the ions gives rise to drifting electrons
with an avalanche amplification as they approach a micro-strip anode structure.
The scintillating light, generated during the electron drift and avalanche
stage, is collected by four vacuum photomultipliers. The position
reconstruction is performed via software algorithms. The JUDIDT readout
electronics was modified at ZEA-2 to cope with the data acquisition
requirements of the prototype. The results of the commissioning of the
electronics are here presented and commented.Comment: Corresponding Author: R. Fabbri; 22 pa
