The paper presents a study of the depth dose distribution for a pulsed electron beam with a wide kinetic energy spectrum for polyethylene target. Electron beam was generated by ASTRA-M accelerator (up to 350 kV of accelerating voltage, up to 0.6 kA of total beam current, 150 ns of beam pulse duration at FWHM). The research was carried out for two accelerator operation modes, providing different spectra of electron kinetic energy (200 kV and 300 kV of accelerating voltage amplitude). Operation modes were adjusted by the software, changing the charging voltage of the accelerator power source only. It was found that the form of depth dose distribution depends on the accelerator operation mode. Possibility of using software settings of the accelerator charging voltage for creation a required depth dose distribution in irradiated material was analyzed based on the study results.
