MPROVEMENT OF CO-BASED AMORPHOUS CORE FOR UNTUNED BROADBAND RF CAVITY

We have developed a cobalt-based amorphous core as a new magnetic-alloy (MA) core for the loaded RF cavity. Owing to its permeability found to be approximately 1.5 times higher than that of FINEMET FT-3M, this MA core is an excellent candidate for constructing a compact broadband RF cavity with less power consumption. In thisreport, we present our recent studies of the Co-based amorphous core concerning, its annealing temperature and insulating materials coated on the amorphous tape
