Repetitively Pulsed Backward-Wave Oscillator Investigations

摘要

The Pulsed Power and Plasma Science Laboratory at the University of New Mexico(UNM) has completed its initial phase of research on repetitively pulsed high power backward-wave oscillators (BWOs). The aggressive program that we had established seeked to address three basic goals: (1) Understand the physics of high efficiency vacuum BWOs using the Sinus-6 repetitively pulsed electron beam accelerator, (2) study vacuum and initiate plasma-filled long pulse BWO operations using the modified PI-110A accelerator, and (3) Study the prospects of incorporating ferroelectric ceramic cathodes in high power electron beam-driven microwave sources to improve their operations in the long pulse regime.
