- Аннотация: Modern requirements for the devices used in fields of high-energy radiation technologies (nuclear medicine, atomic physics, and space research) determine new the requirements for the sensors and detectors and their working elements. Thus, the devices of nuclear and space technology operate in harsh conditions under intense electromagnetic radiation. The working element of the high-energy radiation detector is scintillation material. One of the promising and studied scintillation materials is garnets due to the wide possibilities of isomorphic substitution of cations and the introduction of alloying additives. It is this feature of garnets doped with rare-earth elements that allows us to control the properties and determine new areas of their application in the future.New cerium-doped scintillation garnets Gd3Al2Ga3O12:Ce (GAGG:Ce) first synthesized in 2011 are currently considered for applications in the various fields: nuclear medicine, high energy physics, space research, security systems, radiological exploration, lighting. However, their fundamental properties are not sufficiently studied; in particular, the process of defect formation in these crystals remains unclear. Getting insight to the defects structure and its formation in multicomponent oxide single-crystal dielectric materials is nontrivial task. The study of the irradiation effects on ion structures is a productive method for investigation of the origin of the defect structure and mechanisms of its formation.
