Title:
ＲＦ空洞に加速電場を高速で立ち上げる方法
Document Type and Number:
Japanese Patent JP7079489
Kind Code:
B2
Abstract:
To provide "a method for establishing acceleration electric fields in RF cavities at high speed" for forming predetermined electric fields in two RF cavities having different characteristics at high speed using a single RF source.SOLUTION: A high-frequency accelerator comprising a first RF cavity and a second RF cavity having a tuner and a single RF source for making the RF cavities having different characteristics form acceleration electric fields forms the acceleration electric fields of both RF cavities to predetermined electric fields at high speed by: detecting resonant frequencies of both of the RF cavities at the time of actuating the RF cavities; modulating an RF frequency of RF power so as to agree with either of the resonant frequencies obtained via the detection and outputs the RF power; and making the resonant frequencies of both RF cavities agree with each other by controlling the tuner and reducing reflection power from both RF cavities by making resonant frequencies of the first RF cavity and the second RF cavity agree with the RF frequency of the RF power to make the RF power and RF frequency output from the RF source reach predetermined values in a short period of time.SELECTED DRAWING: Figure 1
