Compact electron linacs for radiation technology systems

Compact, self-contained electron beam systems are used for sterilization of medical devices and materials, treatment of medical and infectious wastes, non-intrusive inspection of cargo containers, etc. These systems, having massive local radiation shielding, require compact accelerators. 5-MeV and 7-MeV electron linacs are presented in this paper. The accelerators use standing wave biperiodic structures fed by magnetron generators with 2.8 GHz frequency. The accelerators do not use an external magnetic field for the beam focusing. Bunching, acceleration and focusing of the beam are performed by an RF field of the accelerating structure.
