We have developed an electrical circuit model for simulation of parameters of the ASTRA-M pulsed electron accelerator with sub-microsecond pulse duration for optimization its operation. The paper describes a substitution circuit of the accelerator, development of the equivalent circuit in simulation environment and comparison of the simulation results with experiment for a range of simulated parameters. The simulation model of the accelerator consists of two enlarged units: a pulsed generator of accelerating voltage and electron diode. The operation mode of the first unit is determined by the variable parameters of the second unit. Good agreement between experimental simulation results allowed us using this model to analyze the modes of accelerator operation which are not feasible experimentally. Having analyses the simulation result we found optimal parameters of the electron diode which provide the highest efficiency of accelerator operation in two modes: electron beam generation in vacuum and ejection of the beam into the atmosphere. Optimal parameters of the diode found though simulation were used for real application of the ASTRA-M accelerator as a source of ionizing radiation.
