The processing method for obtaining the high-quality surfaces of TlBr single crystals, providing removal of a mechanically destroyed surface layer by chemical etching, is developed. The crystals grown from the melt of purified materials by the Bridgman-Stockbarger method were used for the experiment

The combination of distillation, Bridgman-Stockbarger, hydrothermal recrystallisation and travelling molten zone (TMZ) methods were used for TlBr purification. Grown crystals were characterised by XRD rocking curve and FTIR spectroscopy methods, and by electrical measurements made from 200 to 300 K.
TlBr is a promising material for gamma-ray detectors; however, it has crystal quality problems originated from the crystal growth itself and further treatments during detector fabrication. The effect of technological improvements on crystal quality has been studied in this work. Low performance of s
We report on a digital pulse processing algorithm for correction of charge trapping in the planar TlBr detectors. The algorithm is performed on the signals digitized at the preamplifier stage. The algorithm is very simple and is implemented with little computational effort. By using a digitizer with
