Phase locking of ultra-high power relativistic magnetrons

Phase locking of ultra-high power (≥ GW) microwave oscillations has been achieved. In this article, the authors present experimental and theoretical results of an on-going program to investigate the feasibility of phase-locking of two simultaneously driven relativistic magnetrons. Theoretically, they discuss phenomenological modeling using relativistic pulse shapes. Experimentally, they describe experimental setup and operating characteristics, examine locking criteria, present temporal phase measurements, and compare with analytical results of the phenomenological modeling
