ABSTRACT:
This invention relates to an anode assembly for a magnetron used to generate microwaves in a microwave oven. An object of the invention is to inexpensively prevent the generation of gas due to impurities within the active space within the anode assembly. Such gas can interfere with the movement of thermally excited electrons within the active space and thereby cause abnormal oscillation of the microwave energy output. In the invention, the surfaces of the magnetron's hollow anode cylinder and plate-shaped anode vanes are made of electrical-grade copper with a coating of oxygen-free copper having an extremely low impurity content.
