Abstract:
Capabilities of broadband phase and power control in injection-locked magnetrons were studied with a CW 2.45 GHz, 1 kW microwave oven magnetron. The study was aimed at the investigation of possible application of magnetrons for powering Superconducting RF (SRF) cavities in intensity-frontier accelerators. The study demonstrated that the magnetron RF phase can be controlled by injection of signal at power levels as low as about -12 dB in a frequency band of a few MHz with low phase and amplitude noise. Experiments verified that combining power of two injection-locked magnetrons with 3-dB hybrid yields a broadband phase and amplitude control in SRF cavity fed by the magnetron power station. The paper also discusses a simple theoretical model based on a kinetic approach which considers phase focusing in magnetrons and substantiates the experimental results.
