Abstract
An anode structure for a magnetron provides for low eddy currents and efficient water cooling. The anode structure may be made by machining a bimetal blank including an out layer of a first metal and an inner layer of a second metal and formed by explosion bonding. The second metal has a resistivity lower than first metal and a thermal conductivity higher than the first metal. The machining may result in the anode structure with vanes each having a center (tip) portion made of the second metal and the rest made of the first metal. The machined anode structure may be coated with the second metal.
Claims20
An apparatus for operating as an anode in a magnetron having a cathode, the apparatus comprising:
- a cylindrical wall made of a first metal;
- and
- vanes extending inwardly from the cylindrical wall and configured to define a cavity to accommodate the cathode, the vanes each including a base portion made of the first metal and connected to the cylindrical wall and a center portion made of a second metal and connected to the base portion.
An apparatus for operating as an anode in a magnetron having a cathode, the anode to be cooled using a cooling fluid, the apparatus comprising:
- a cylindrical wall;
- and
- vanes extending inwardly from the cylindrical wall and configured to define a cavity to accommodate the cathode,
- wherein the cylindrical wall and the vanes are formed by machining a single bi-metallic blank including an outer tube of a first metal and an inner tube of a second metal, the inner tube placed in and bonded to the outer tube.
