Non-tunable high-frequency accelerating cavity, accelerator, and method for adjusting impedance of non-tuned high-frequency accelerating cavity

摘要

PROBLEM TO BE SOLVED: To provide: an untuned high-frequency acceleration cavity, simplifying an installation operation of a magnetic body core, and also capable of improving flexibility of selection of a magnetic body core; an accelerator; and an impedance adjustment method of an untuned high-frequency acceleration cavity.SOLUTION: An untuned high-frequency acceleration cavity includes: a first vacuum duct 11 with conductivity through the inside of which charged particles pass; a second vacuum duct 12 with insulation properties at the inside of which an electric field accelerating charged particles is generated; an inner conductor 13 connected vertically to the first vacuum duct 11 at one end thereof; an annular magnetic body core 14 surrounding the inner conductor 13; and a housing 15 with conductivity surrounding the first and second vacuum ducts 11, 12, the inner conductor 13, and the magnetic body core 14.SELECTED DRAWING: Figure 1
