Research and Development on High-Power Crestatrons for the 100-300 mc Frequency Range

摘要

A series of trajectory plots for a reduced diameter P sub mu = 20 gun is shown. A reasonably well-behaved beam throughout the gun region is obtained. The electrostatically focused tube using one of the improved P sub mu = 4.46 guns is seen to yield only fair transmission to the collector at reduced voltages. Some low-level oscillations appear to limit the transmission. The revised design of the 100-watt Crestatrons has resulted in a tube with sufficient gain and power output. Only very minor modifications in the design have been found to be necessary for the final tubes. (Author)
