Abstract :
This paper describes the mechanical and electrical features of a 23-inch TWT package for ruggedized airborne service. The package consists of a hollow-beam air-cooled tube and a foil solenoid. The package has a nominal power output of 300 watts CW in the range of 500 to 1,000 Mc. The package is 23 inches long and has an outside diameter of 
inches. The maximum weight is 38 lbs. Several novel features are incorporated, such as a thermal interlock switch, isolated helix, and a transverse air-cooling system. The RF structure utilizes a tape helix supported by three ceramic rods. The electron gun is an immersed hollow-beam type. Cathode current densities are in the order of 0.8 amp/sq cm. A barium-tungsten dispenser cathode is utilized.
