PROBLEM TO BE SOLVED: To provide a low-temperature charged particle beam treatment accelerator for reducing the weight of the component of an accelerator and reducing costs greatly by accelerating, storing, and taken out low-emittance beams that are strong "cold ion beams". SOLUTION: A beam size is reduced greatly in an electron beam cooling device 6 by a low-emittance EBIS-type ion source or hollow beams. COPYRIGHT: (C)2007,JPO&INPIT
