摘要： Disclosed is a magnetron for a microwave oven which has a drain electrode (60) near a cathode (25) and in a position where an electron beam path is not interfered with. The cathode and the drain electrode are formed in spiral shapes. Turns of the cathode are alternately arranged with those of the drain electrode. When the magnetron is operated, the drain electrode is kept at the same potential as the cathode or is kept at a negative potential relative to that of the cathode. Therefore, positive ions in the vicinity of the cathode are collected at the drain electrode, thus decreasing high frequency noise.

摘要： 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.
