| Abstract: | A stochastic-deterministic model of a discharge induced by space charge in dielectric is developed. The spatiotemporal and current characteristics of the discharge are simulated numerically. The simulation results are compared with the experimental data on discharges in polymethylmethacrylate samples charged by means of an electron beam. The interrelation among the growth of the current-carrying channels, energy transfer, and energy release during the discharge is discussed. |
