Influence of manufacturing conditions of detectors based on crystals of SrI2:Eu on their scintillation characteristics

The factors determining the characteristics of the SrI2:Eu scintillator during processing and packing stages are considered. Using experimental and computer modeling, we selected options for processing the surfaces of scintillators, providing an improvement in their scintillation characteristics. It is shown that the method of processing the surface of crystal Sr-2:Eu size of empty set21x5 mm and empty set21x10 mm grown by method of synthesis of raw materials components, combined with the diffuse reflector Tetratex provides improved energy resolution of 3.65 % and 3.87 % respectively at 662 keV.
