RESEARCH ON MILLIMETER-WAVE TUBES.
Abstract
Research was continued on the development of millimeter-wave tubes. The program to build a 100 W cw tube amplifier at W-band is described. The emphasis was on making the tools, parts, and equipment necessary to assemble the first rf tube. All possible assembly techniques were tried and proven. Construction of the first tube was started. Efforts were continued on a feasibility study of a 5 mm (55Gc) amplifier which eventually will deliver 30 W of cw power at 2 mm (150hc). A 20 kV low gain experimental amplifier using the short-fingered interdigital slowwave structure was built and tested at 5 mm. Although use of an electron gun not intended for the final version of this amplifier complicated the test procedures, essential agreement with predictions was obtained. Extensive studies of the Model 75 electron gun which is designed for the eventual amplifier were carried out in the magnetic demountable beam tester. In the course of these studies, several aspects of various theories were verified for the first time. (Author)
