Abstract
A standing wave linear accelerator with a prebunching section and an accelerating section that are formed into a unitary accelerating structure is described. The prebunching section is configured to group charged particles into bunches by velocity modulation of the charged particle beam. The accelerating section has a plurality of inter-coupled resonant cavities, including an input cavity that is coupled to the prebunching section and an output cavity.
