Theoretical and Experimental Investigation of Electron Beam Acceleration and Submillimeter Wave Generation.
Abstract
The objective of our research is to investigate the physics as well as to develop the technology of compact submillimeter-wave devices.(1) A revolutionary new device, the gyro-frequency multiplier, which can potentially generate 50 kW at 1-2 Thz by using a 140 GHz gyrotron as its input source, has been tested in our laboratory. (2) Our second-harmonic gyro-TWT amplifier, which is based on our recent marginal stability design (MSD) procedure, yielded extremely good results, including a record setting output power of 207 kW, with 13% efficiency, 16 dB saturated gain, 2% bandwidth and was completely stable. (3) The MSD procedure was also used to design two other stable, high performance amplifiers: a 1 MW, 140 GHz, third harmonic gyro-TWT and a 100 kW CW, 95 GHz, TE(01) gyro-TWT. (4) We have also begun a major new program to develop high power, ultra-wideband prebunched FELs for radar applications using a photoemitted rf gun (5) We have also continued to construct a high-performance 250 kW CW, 33.2 GHz TE(01)TE(02) gyroklystron amplifier and begun a 70 kW CW, 95 GHz, third harmonic, smooth bore gyroklystron amplifier program.
