Development of High-Power Pulsed Klystrons for Practical Applications

This paper describes the development of three practical, sealed-off, tunable klystrons intended for operation in the region of 1 to 2 megw at the S, L, and X radar frequency bands. These tubes are an outgrowth of the previous development at Stanford of a 30-megw S-band klystron in conjunction with the billion-volt linear electron accelerator program. Similar design principles apply to all of these tubes, but the three smaller klystrons described make use of cavity tuning methods appropriate to the three frequency bands.
