  • Vector control of radio frequency signal in narrow band loads driven by injection locked magnetron using carrier amplitude modulation by spectral energy spreading via phase modulation
    Patent number: 10477668
    Abstract: A method, system, and apparatus for vector control of radio frequency signals in narrow band devices such as Super-conducting Radio Frequency (SRF) cavities driven by injection locked magnetrons using carrier amplitude modulation by spectral energy spreading via phase modulation comprises coupling a magnetron to a cavity associated with a particle accelerator and injection locking the magnetron. A modulated amplitude and modulated phase of a drive signal is provided to the magnetron powering the cavity associated with the particle accelerator by removing power from a carrier according to a modulation scheme and providing vector control of the cavity radio frequency vector.
    Type: Grant
