Abstract
A low-voltage, multi-beam radio frequency source that operates at a voltage less than or equal to approximately 20-40 kV and that generates at least 600 kW at a pulse width of approximately 5-30 ms. The RF source includes an electron gun having a cathode configured to generate a plurality of beamlets. An input cavity and output cavity are common to the plurality of beamlets. A plurality of gain cavities are provided between the input and output cavities, each having a plurality of openings corresponding to the plurality of beamlets. The cathode may include 10-20 beamlet cathodes formed in a ring, each being configured to generate a single beamlet and each having beamlet optics independent of each other. A beam collector having a plurality of openings corresponding to each of the beamlets may be provided within the output section, where the openings have no RF coupling to each other.
