Abstract :
A new type microwave dummy-load using SiC ceramic, which has an indirect water cooling structure, was successfully operated with up to 50-MW of rf power at a 1-μs pulse width and 50-pps repetition rate in the S-band frequency. The input VSWR obtained was less than 1:1.1 at the maximum rf power. The vacuum pressure in the rf-load raised from the base pressure of 1×10-6 Pa with no rf power to 2×10-6 Pa at the maximum rf-power; and there was found to be no special outgassing from the SiC-ceramics
