Pasotron Technology.
Abstract
This annual report describes research progress made in the second year of the PASOTRON Technology Program. This program is a two year effort sponsored by the Air Force Office of Scientific Research to develop and investigate a single-stage amplifier and a multi-stage oscillator; each based on Hughes' Plasma-Assisted, Slow-Wave Oscillator (PASOTRON) technology. During the program's second year amplifier performance was briefly re-explored to take advantage of system and diagnostic upgrades implemented by HRL under a parallel IR&D Program; and the first stage of the multi-stage oscillator was demonstrated. Data is reported showing improved amplifier performance. Amplifier gains of 10-to-17 dB were maintained; while instantaneous bandwidth was increased from 0.1% to 1.0%. Amplified power levels of several tens to hundred kilowatts were measured to give a factor-of-ten increase in efficiency to levels of a few present. The first phase measurements were completed, and coherent amplifier operation was achieved with phase stability of up to 0.005 deg/V. Additionally, a multi-stage oscillator system was designed and experimental investigations were conducted on the first stage of the three-stage apparatus. Characterization of the second and third stages will be completed during the program's three-month no-cost extension.
