| CW resonance accelerator with high average power electron beam is developed at RFNC-VNIIEF. Electron energy range is varied from 1.5 to 7.5 MeV and average beam current is up to 40 mA. Electrons obtain the required energy by several passing of coaxial half-wave accelerating cavity. In this paper we present the results of electron beam dynamics simulation during its acceleration and transportation. The operating parameters of RF system, beam optics and bending magnets are determined. These parameters permit to obtain output beam with minimal current losses on each accelerating stage. As a result of carried out tests we obtained 7.5 MeV electron beam after five passes of accelerating cavity. The electron energy spectrum, average beam current, transverse beam dimensions were determined on each accelerating stage. Common beam current loss is under 10 %. | ||

Linear resonance electron accelerator LU-10-20 is under operation in RFNC-VNIIEF since 1994*. LU-10-20 is aimed at carrying out radiation processing of materials and researching radiation processes. The energy of accelerated electrons is up to 10 MeV, the average beam power - up to 12 kW. This accelerator has demonstrated that it is highly useful for performing radiation researches and tests. As of today work is underway on modernization of LU-10-20 including its accelerating structure and RF power supply. Accelerating structure is aimed at electron beam acceleration up to nominal energy and consists of complicated resonance TW RF structure, which uncluded iris-loaded waveguide, input and output matching devices. The paper presents the electrodynamic calculation results of modernized accelerating structure, input and output matching devices, and also beam dynamics calculation results.
