RESEARCH AND DEVELOPMENT ON HIGH-POWER CRESTATRONS FOR THE 100-300 MC FREQUENCY RANGE

摘要

Several trajectory plots obtained in the design of the P = 20 hollow-beam gun are described. It is found that further work is necessary before a well focused beam will be obtained.nA number of 100-watt Crestatrons have been tested. Several methods of increasing the power output of these tubes are described. They are an improvement of the electron gun and the r-f matching sections. In order to improve the efficiency of the tubes, advantage of phase-focusing tech-niques and depressed potential collectors will be taken in future tubes.
