Abstract :
The authors report the injection locking results of a long-pulse (200-400 ns) high power (20-30 MW) relativistic magnetron at 3.3 GHz. Phase-locking with reproducible locked angle was achieved with an injection power ratio as low as 1:200. The locked states were phase stable to within +or-30 degrees during the pulse. Phase locking physics was studied and important effects due to frequency pushing were identified. The locking bandwidth and the dependence of the final locked phase on injection parameters were measured and found to agree well with theory.<>
