2017
In this study we identified patterns of accumulation of space charge in dielectrics irradiated by electrons with energies of 1-10 MeV, studied the physical processes of accumulation of space charge and an electrical field in the volume of the irradiated dielectric. Determined quantitative criteria for the occurrence of electrical breakdown in the bulk of dielectrics, carried out mathematical modeling and laboratory investigation of the phenomenon under study. Studied the principles of operation of computer programs GEANT4 and DICTAT, have acquired practical skills with these programs, which conducted computer modeling of charge accumulation and the emergence of the electric field in the volume model of dielectrics irradiated by streams of electrons. Performed laboratory experiments on the detection of electrical discharge in a glass sample irradiated by electron beam with energy of 10 MeV.
