Research program on a compact and high-power microwave tube

Abstract : A research program on a compact and high-power microwave tube has been initiated for applications to microwave weapons. The proposed microwave tube is a phase-controlled amplifier based on the newly developed cusptron microwave tube concept. The objective of this program is to develop a cusptron amplifier of 5-9 GHz, 80-100 MW, 10 microsec pulse length, and 1-10 kHZ repetition rate. The immediate goal is the construction of a medium power tube of 5-9 GHz, 200-250 KW, 10 microsec pulse length, and 1 KHz repetition rate. The program covers a three year period, CY 86-88.
