Normandy, Tennessee 37360-9715 Contact: Larry Barnett Phone: (931) 212-7349 Abstract: W-Band cyclotron harmonic gyrotron devices at 95 GHz will be investigated as potential compact and field deployable sources of high power microwaves for Area Denial Technology applications. Oscillators operating on the 2nd to the 8th cyclotron harmonics will be investigated. These gyrotron studies will be aimed at the design and engineering evaluations of harmonic devices in the 30 to 300 kW output power range where overall system efficiencies, reduced system sizes, fast system start-ups, and low to zero standby powers, are of paramount importance. It is anticipated that low harmonic devices with electron beams of the order of 50 kV to 100 kV that will attain >100 kW CW, or average, output power at high efficiency will receive the bulk of the theoretical attention. Devices with both normal and permanent magnets will be investigated and one or more complete designs, including magnets, will be accomplished. Benefits: The commercial applications of W-band cyclotron harmonic gyrotron oscillators utilizing normal or permanent magnets would be in materials processing, brazing and joining, heating, directed energy, plasma heating, and other scientific applications. Techniques learned will directly apply to high power coherent amplifiers for communications and radar. Return
