無同調高周波加速空洞で用いるCo基アモルファスコアの開発

We have developed a cobalt-based amorphous core as a new magnetic-alloy(MA)core for the loaded RF cavity.Because of its permeability found to be approximately twice as high as that of FINEMET,this MA core is an excellent candidate for constructing a compact broadband RF cavity with less power consumption.In this report,we present our recent studies of the Co-based amorphous core\u27s physical properties,performance,and development
