Abstract

A magnetron comprises an anode cylinder, an even number of vanes radially extending from the inner wall of said anode cylinder and forming together with the anode cylinder a resonant circuit, and sealing members hermetically sealed to the opposite ends of said anode cylinder via seal flanges and respectively connected to a microwave power output section and to a cathode support stem. The anode cylinder and vanes are made of aluminum or an aluminum alloy, the sealing members are made from iron plates, the seal flanges are aluminum-clad iron plates, the sealing members are welded to the seal flanges, and the seal flanges are soldered by aluminum solder to the opposite ends of the anode cylinder.
