ABSTRACT:
A high frequency electromagnetic energy absorber disposed near a cathode holder in an evacuated envelope of a magnetron so as to attenuate high frequency noise leaking through the cathode terminal of the magnetron. The absorber is in thermal contact with a member connected to the anode cylinder of the tube to conduct heat generated in the tube, whereby overheating of the tube can be prevented. By combining the absorber with another high frequency attenuating element, the attenuating effect can be increased.
