25 July 1989 Strongly Coupled Relativistic Magnetrons For Phase-Locked Arrays
Author Affiliations +
Phase-locking of two relativistic magnetrons has been achieved at power levels of ≈ 3 GW at 2.8 GHz by connecting a short waveguide coupler of length LC ≈ n λ/2 between vanes. Phase-locking is demonstrated by both phase-sensitive diagnostics and power density enhancement due to source coherence in the radiation field. Phase-locking occurs in ≈ 5 ns and is reproducible. Extension to 10-100 GW appears feasible with magnetron arrays. Issues in operating arrays of coupled oscillators are discussed; an experimental approach to resolving these in a 4-magnetron module (expandable to a 7-magnetron module) is described.
