| Sumario: | Title screen The study demonstrates the possibility of predicting the energy spectrum of a wide-aperture (750•150 mm) electron beam outputted into ambient air through a thin metal foil on an electron accelerator with a grid plasma cathode. This type of accelerators features a weak mutual dependence of the electron beam parameters (electron energy, beam current, pulse duration, repetition frequency), and the beam spectrum can be reconstructed using experimental attenuation curves of the beam current through thin metal foils and the Tikhonov regularization with minimum a priory assumptions. Such spectra reconstructed for different accelerating voltages (110-160 keV)are presented, and research data are reported suggesting that the beam energy spectrum depends only slightly on the operating gas pressure and that it broadens mostly due to scattering of the beam in the output foil and in ambient air. Decreasing the accelerating voltage during a beam current pulse provides predictable broadening of the beam energy spectrum with a shift of its peak toward the lower energy, and this can be valuable for efficient use of such accelerators both in science and technology.
