Paper Abstract

Long-term stability of TlBr detectors with Tl electrodes was evaluated in this study. Tl/TlBr/Tl detectors were fabricated and tested with a charge sensitive preamplifier and a spectroscopy amplifier and a gated integrator. Significant improvement of energy resolutions was realized by applying the gated integrator to the TlBr detectors. The full-energy peak positions, counts and resolutions for 662 keV gamma-rays from 137Cs were monitored during the course of measurements (10 days). By changing the polarity of the applied bias voltages every 24 hours, the Tl/TlBr/Tl detectors exhibited stable spectroscopic performance for totally over 240 hours.
