Abstract
We report the first gyrotron‐backward‐wave‐oscillator experiments to produce high power (tube power of ∼1–8 MW), long‐pulse (0.3–1.2 μs) microwaves at high currents (0.1–2 kA) and high voltages (650–750 kV). Experiments were performed in the TE11 fundamental backward‐wave mode, with efficiencies of ∼1%–2%. Mode competition was observed which is believed to originate from the TE21 absolute instability.This publication has 9 references indexed in Scilit:
