US 2014/0191657 A1 · COAXIAL MAGNETRON

Abstract

The object of the presently disclosed embodiment is to improve heat dissipation and an overall cooling efficiency to raise a peak oscillation output. To achieve the object, there is provided a coaxial magnetron having the following configuration: Around a cathode, vanes and an anode cylinder form an anode resonant cavity, and a cylindrical side body forms an outer cavity. An input side structure having an input part and an upper structure are joined to both ends of the cylindrical side body. One end of the anode cylinder is joined to the input side structure. A groove (or step) for adjusting the distance between the structures and at the both ends is provided, and the groove is joined to the other end of the anode cylinder.

A coaxial magnetron, comprising:

a cathode;
an anode having an anode cylinder and vanes for forming an anode resonant cavity around the cathode;
a cylindrical side body forming an outer cavity coaxial with the anode resonant cavity around the anode cylinder;
a pair of end sealing structures joined to both ends of the cylindrical side body;
and
an input part connected to the cathode through one of the end sealing structures,
wherein one end of the anode cylinder is joined to one of the end sealing structures, and the other end of the anode cylinder is joined to a groove or a step of the other of the end sealing structures, the groove or the step being formed on the inner surface of the other of the end sealing structures.
