Knowledges of pulsed electron beam characteristics is necessary for use it for scientific and practice applications. Current work analyses the pulsed electron beam extracted from the vacuum diode through a titanium foil (60 mkm) of the diode exit window. Electron beam energy depth distribution was measured for a target made of different number of aluminum foils. A pulsed electron beam with a wide range of kinetic energies was generated by the ASTRA-M accelerator (260 kV of accelerating voltage, up to 1 kA of beam current, 150 ns of beam pulse duration at FWHM). A calorimeter of total absorption and Faraday cup were used to measure beam characteristics. Calorimeter included two collectors: first one measures a beam energy after aluminum foils, and the second one measures a total beam energy. All measurements were performed at 10 −5 Torr background pressure after the exit window foil. As a result, the electron kinetic energy spectrum of the beam out of diode has been reconstructed.
