The Study of Mechanisms Radiation-stimulated Defects Formation in the Magnesium-aluminum Spinel Under Electron Irradiation

Year: 2025

Type: conference-paper

Abstract: The paper investigated the effectiveness of the formation of radiation-stimulated defects in magnesiumaluminum spinel upon irradiation with high-energy electrons.Initially, a computer model of the experiment was developed in the Geant 4 software environment.The simulation results showed that defects in the crystal lattice of spinel occur both when atoms are directly knocked out of nodes and when photonuclear reactions occur when irradiated with electrons with energy above the photofission threshold.Single-crystal spinel samples were irradiated with primary electron energies of 10, 15, 20, and 25 MeV in the atmosphere, with a fluence of 2•10 16 cm -2 , on the LUE-30 linear electron accelerator of the NSC KIPT.The obtained experimental results, as well as the modeling, showed that photonuclear reactions play a significant role in the formation of defects in spinel crystals under electron irradiation.
