Description

The combination of Bridgman, recrystallization by dissolving in pure water under hydrothermal conditions and travelling molten zone (TMZ) methods were used for TlBr purification. Detectors of 0.5 and 3 mm thickness were produced from a single crystal grown by the TMZ method. The samples had stable spectrometric characteristics from -40 deg. C to room temperature. A resolution of 3.7% at 60 keV (241Am source) was attained for 3-mm sample at 0 deg. C. Electrical and spectroscopic properties of the detectors are reported and discussed
