Calculation and Measurement of the Back-Bombardment Effect in a Standing Wave Technological Linear Electron Accelerator

Abstract

The back-bombardment effect is studied based on the example of the 10 MeV standing wave technological electron linac. The beam dynamics is calculated, the spectra of backstreaming electrons are obtained, and the power released by the backstreaming electrons at the cathode is estimated. The observed effects are in good agreement with the calculations.
