Abstract:

The purpose of the program was to develop a gridded 100 kilowatt L- band traveling-wave tube suitable for application in phased array radar systems. A ring-bar circuit which operates at 23 kv was selected for use in this tube. A perveance 5 gridded solid electron beam gun was developed for this tube. The tube was focused using a solenoid, PPM and single reversal permanent magnet configurations. Power outputs in excess of 100 kilowatts were measured. Beam efficiencies in excess of 30 percent were also measured. The tube was constructed as a grounded cathode tube which required unique techniques for mounting the circuit, the anode, making connections to the circuit, and the development of an rf match to the circuit.
