Abstract

At Budker INP SB RAS, a single module for a new 100 kW industrial accelerator with electron energy of 7.5÷10 MeV has been successfully tested in pulsed operating regime. The accelerator operates at 176 MHz, expected wall plug to electron energy efficiency is 25÷30%. The paper presents the accelerator concept together with simulation results for the accelerating structure, beam injection and dynamics.

The obtained structure electron efficiency of 67% and average electron beam current are close to the expected values. Improvements of beam transportation and energy spectrum due to the injection regime optimization were experimentally proven. The results obtained are discussed.
