Abstract: A particle accelerator comprising a waveguide comprising a series of acceleration cells. The series of acceleration cells comprise an input acceleration cell configured to accelerate a beam of electrons along the central axis of the cells. A source of electrons is configured to input a beam of electrons into the input acceleration cell and a magnet arrangement is configured to prevent electrons that have deviated from the beam of electrons from hitting the source of electrons.

Abstract: A particle accelerator comprises a waveguide configured to accelerate a beam of electrons along an acceleration path. A diversion channel is configured to convey a beam of electrons along a diversion path. A first magnet arrangement is configured to, at a first location, direct electrons from the acceleration path to the diversion path. A second magnet arrangement is configured to, at a second location, direct electrons from the diversion path to the acceleration path.
