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: Disclosed is an RF window. The RF window comprises a first and a second cavity and a plate of dielectric material positioned there between. At least one of the first and second cavities comprises a taper, beginning at the plate, such that the at least one of the first and second cavities reduces in diameter in a direction away from the plate.
