Starzhynskiy M. Physics and technology bases of elaboration of AIIBVI scintillators, their properties and peculiar features of application

Object of studies. Physico-technological aspects of preparation and complex property studies of chalcogenide scintillators and detectors on their base. Work objectives: development of technological aspects of preparation of new types of chalcogenide scintillators on the basis of zinc selenide and other АIIВVI compounds with specified output parameter, as well as their application in detectors of ionizing radiation. Methods of studies and equipment. Thermodynamic modeling, optical, mass-spectrometric and spectral-kinetic methods. Modern devices, non-standard and industrial equipment for crystal growth of AIIBVI compounds. Theoretical and practical results, novelty. Physico-technological methods have been developed for preparation of new highly efficient chalcogenide scintillators on the basis of zinc selenide and other AIIBVI compounds with unique scintillation properties, as well as radiation detectors on their base. Optimum regimes have been determined for raw material preparation, crystal growth andpost-growth annealing. Degree of implementation. New technologies of chalcogenide scintillator preparation have been used in experimental-industrial production at the Institute for Scintillation Materials. Application fields. Modern radiation instrument production, radiography, multi-energy introscopy.
