Anode assembly for electron discharge devices

A magnetron comprising:

• a plurality of substantially similarly shaped conductive members each having a cylindrical boundary wall section and a plurality of radially extending vane sections integrally formed with said wall section and extending inwardly to an electron interaction region;
• and
• said conductive members being bonded to one another by nonthermal metallurgical techniques along a mating edge;
• said vane member sections having notches along opposite mating edges dimensioned to receive at least one annular strap member when bonded together;
• a strap member contacting alternate vane member section notched walls of each of said conductive members.

The method of forming an anode member for a magnetron comprising the steps of:

• forming a plurality of conductive members having curved walls and radially extending conductive vanes extending from said curved walls to free ends;
• positioning at least one conductive strap in contact with alternate vanes;
• and
• joining said members and said strap by nonthermal techniques into a composite anode.

The method of forming a magnetron comprising the steps of:

• forming an anode with a cylindrical wall having a plurality of vanes extending radially from said wall and defining a plurality of cavity resonators with at least one annular strap contacting alternate vanes, each vane formed from at least two substantially similarly shaped conductive members joined by nonthermal metallurgical techniques;
• supporting said anode and a cathode in an envelope insulated from each other;
• and
• evacuating said envelope.
