Abstract:

This 15-month program involved the design, fabrication, and test of a 3.2 millimeter-wave, 10 kW pulsed distributed interaction klystron designated the HOW-2. The electrical feasibility of this exploratory development model tube was established during an investigation under an earlier Electronics Command Contract. A major portion of the program was devoted to both the design of the highly sophisticated electron gun which has a compression ratio of 400, a microperveance of 0.83, and the distributed interaction cavity structure. Two of the three tubes delivered under this contract successfully demonstrated the desired 10 kW of peak output power with a 0.0005 duty cycle and a 40 nsec pulse width. The output power and frequency are determined by a cathode voltage pulse in the range of 20 to 30 kV. A solenoid is used to focus the electron beam and the collector is air cooled. Author
