INDUCTION CYCLIC ELECTRON ACCELERATOR Russian patent published in 2014 - IPC H05H11/00 

FIELD: physics.

SUBSTANCE: cyclic electron accelerator includes deflecting dipole magnets, an induction accelerating system, beam input and output systems located in rectangular sections. To accelerate electrons in the energy range of 0.3-10 MeV, the accelerator includes a generator for exciting inductor coils of the accelerating system with a rectangular voltage wave. Duration of the accelerating wave pulses is equal not to S, the duration of the orbiting period of the electrons, which is several nanoseconds, but the duration of the full cycle of acceleration from the injection energy go a given final energy of about 10^-4-10^-6 s. To maintain an equilibrium radius of orbit during acceleration and slow ejection of electrons, the accelerator includes a generator for supplying the deflecting dipole magnets, having a property of exciting trapezoidal magnetic induction wave. The accelerator also includes a hard-focusing system in the deflecting dipole magnets and straight sections.

EFFECT: high average power of the accelerated electron beam, reduced size and weight of the accelerator, simple accelerating system and wider range of controlling energy of accelerated electrons.
