A possibility of reconstructing the electron beam spectrum from the dependence of beam extinction on foil thickness is demonstrated. The electron energy distributions are calculated using Tikhonov’s regularization of the Fredholm integral equation with the least number of a priori assumptions on the beam spectrum shape. The spectra experimentally obtained in a vacuum diode loaded by nanosecond voltage pulses are reconstructed and analyzed.
