Multifunctional scintillation materials of the garnet structure for non-homogeneous detecting cells of electromagnetic calorimeters to operate in a harsh irradiation environment

The scintillator gadolinium aluminium gallium garnet (Gd3Al2Ga3O12, GAGG) was found to be an excellent material for application in non-homogeneous detecting cells for future calorimeters, operating in a harsh irradiation environment. GAGG, activated by cerium ions, can be used to detect gamma-quanta and to absorb efficiently neutrons in a wide energy range. The capture of neutrons is accompanied by the emission of relatively soft gamma-quanta which can be ignored at calorimetric measurements above 10 MeV. These findings create prospects to construct compact detectors for different purposes, from particle physics to industry.
