RADIO-FREQUENCY ACCELERATION CAVITY AND CIRCULAR ACCELERATOR

摘要

PROBLEM TO BE SOLVED: To provide a radio-frequency acceleration cavity and circular accelerator which is controllable for forming a magnetic core having optimum Q-value. SOLUTION: In this radio-frequency acceleration cavity, the gap space of a magnetic core 1 is adjusted by driving a drive unit 7 from a control device 9 to provide the optimum Q-value. Accordingly, the beam instability is suppressed.
