Abstract
A novel anode structure for electron discharge devices, for example, a crossed field oscillator of the magnetron type is fabricated by uniting nonthermally substantially similar cylindrical members each having a boundary wall member and plurality of vane members. The vane member edges are provided with alternate clearance or contacting mating notches to position an annular strap or straps in the complete anode assembly. Less expensive metal castings, such as aluminum, and other suitable vacuum materials, and such techniques as pressure welding and interference fits may be employed without expensive brazing procedures to result in a simplified less expensive anode structure. Different anode vane configurations are simply implemented, such as V-shapes, utilizing castings or similar structures which when joined together form the composite anode assembly.
