CHARGED PARTICLE BEAM EXTRACTION METHOD BY LOW-TEMPERATURE CHARGED PARTICLE BEAM MEDICAL TREATMENT ACCELERATOR (CBS)

摘要

PROBLEM TO BE SOLVED: To extract beam emittance precisely to a moving three-dimensional complex neoplasm target from a synchrotron while keeping the beam intensity and energy in variable state. SOLUTION: This is a method of extracting a low beam emittance having "cold ion beam" with strong intensity by a special electron beam cooler outside of the synchrotron stably with variable beam intensity and energy. This uses either a charge recombination phenomenon of ion using an electron beam cooler or a super high-speed kicker of 10 kHz having small gap. COPYRIGHT: (C)2007,JPO&INPIT
