Abstract
A magnetron comprises an anode with an anode axis and an antenna terminal disposed along an antenna axis. The antenna axis is offset from and parallel to the anode axis. A cooling element surrounds the anode for cooling the anode. The outermost periphery of the cooling element which forms the overall shape of the magnetron has a longitudinal center axis disposed coaxially along the antenna axis to permit the adaptability of the magnetron to substantially all types of oven waveguides.
