Critical Analysis of Industrial Electron Linacs

The electron Linacs found wide industrial and medical applications. Industrial Linacs include systems for scanning and output electron beam to air with foil window. The critical analysis of electron Linacs for the treatment of materials (degradation of PTFE, curing of composites and others) and food safety is considered in this report. The kind of radiation technologies on the basis of electron beams determines the type of electron Linac. Main physical demands for industrial electron accelerators consist in the variations of beam parameters such as a kinetic energy, power. Questions for regulation of these beam parameters are considered. Scanning electron beam systems with parallel trajectories for electrons are discussed. The level of absorbed doses in the irradiated product and throughput determines the main parameters of electron accelerator. The variant of ideal electron Linac for industrial applications is discussed.
