Parallel coupled cavity structure with constant magnets focusing system

Abstract

Accelerator for intensive electron beam (average current up to 2 A) from energy 50 keV up to energy 3-5 MeV is offered. Accelerating structure consist of a few resonators fed parallel from one waveguide. Focusing system contains constant radial magnets located between accelerating resonators and creating the axial alternating-gradient focusing magnetic field. Geometry and results of beam dynamics calculation such kind accelerator are presented.
