A system for monitoring intensity of a particle beam can include one or more radio-frequency (RF) detectors coupled to a signal analyzer that can be placed outside the radiation field of the particle beam. Each RF detector can include a gas-filled RF cavity coupled to one or more gas-filled waveguides. The signal analyzer can self-calibrate before the particle beam is turned on for determining one or more absolute intensities of the particle beam when the particle beam is present.

Gas-filled radio-frequency beam detector

A system uses one or more magnetrons to generate pulsed radio-frequency (RF) power, such as for powering an accelerating cavity. The one or more magnetrons each having a self-excitation threshold voltage and configured to operate with internal modulation using a pulsed RF input signal to produce the pulsed RF power when being powered by a direct-current power supply at a voltage level below the self-excitation threshold voltage.

Pulsed power generation using magnetron RF source with internal modulation

A system and method of operating a magnetron power source can achieve a broad range of output power control by operating a magnetron with its cathode voltage lower than that needed for free running oscillations (e.g., below the Kapitsa critical voltage or equivalently below the Hartree voltage) A sufficiently strong injection-locking signal enables the output power to be coherently generated and to be controlled over a broad power range by small changes in the cathode voltage. In one embodiment, the present system and method is used for a practical, single, frequency-locked 2-magnetron system design.
