Abstract
A linear accelerator with improved efficiency is disclosed. The linear accelerator contains at least one lower beam energy recirculating linear accelerator which is focused along a constant focal length, and at least one higher beam energy recirculating linear accelerator which is focused along a constant focal length, and a full energy recirculating line which received the beam from the higher energy recirculating linear accelerator and reinjects it into the higher energy recirculating linear accelerator, thereby balancing the focusing profile to the beam energy. Better envelope control, focusing, and higher efficiency is observed in linacs according to the present invention.
