Development of traveling-wave tubes for radar operation

The design of a pulsed traveling wave tube for use as a power driver for megawatt klystrons will be described. The tube will provide more than 5 kw of peak power output over a frequency range of 1.5:1 with 30 db gain in the Ultra High Frequency region. The ease in adapting the same construction to other frequency ranges will be described. An analysis of the beam focusing, r. f. coupling and attenuators used in this tube will be described including the procedures followed in order to eliminate spurious oscillations. The constructional details of the tube will be shown and the assembly techniques for small production quantities will be described.
