HIGH-POWER HYBRID MULTIPLE-BEAM KLYSTRON FOR PHASE ARRAYS.
Abstract
Efforts concern development of a multiple-beam klystron amplifier for use in phased arrays. The design drawings for the single-beam prototype have been completed, except for small changes still required in the cathode and focusing electrode dimensions to obtain adequate beam transmission. The design of the 15-beam tube has progressed. The gun design program has continued with both computer calculation of beam trajectories and experimental tests in the beam tester. The design of the loaded double-tuned cavities has been completed and the related mechanical problem of fastening the silicon carbide has been solved. Two-stage matching units for the transition between the iterated input guide and standard WR-137 guide have been designed and tested. Measured VSWR of an assembly of two pairs of units and an 8-section iterated guide was 1.2 at the band edges and below 1.1 over most of the band. The thermal design of the collector, requiring dissipation of 12.5 KW over a length of 3-3/4 inches and an outside diameter less than 1.4 inches (the beam-to-beam spacing), was completed. A helical water channel was adopted after a computer program combining the equations for heat transfer and pressure drop had been written. The window program continued with an investigation of matching requirements, and a simple design was determined.
