Phase locking of relativistic magnetrons
Abstract
Phase locking of relativistic magnetrons has been achieved at power levels of ~3 GW at 2.8 GHz, exceeding previous phase-locking power levels by 3 orders of magnitude. Two relativistic magnetrons interact directly through a short waveguide of length l~nλ/2 to allow locking. Power-density enhancement due to source coherence is directly measured in the radiation field. Phase locking occurs in ~5 ns and is reproducible. Extension to 10-100 GW appears feasible with arrays of oscillators.
