Abstract
A multi-frequency klystron has an electron gun which generates a beam, a circuit of bunch-align-collect (BAC) tuned cavities that bunch the beam and amplify an RF signal, a collector where the beam is collected and dumped, and a standard output cavity and waveguide coupled to a window to output RF power at a fundamental mode to an external load. In addition, the klystron has additional bunch-align-collect (BAC) cavities tuned to a higher harmonic frequency, and a harmonic output cavity and waveguide coupled via a window to an additional external load.
Claims2
A multi-frequency klystron comprising:
- an electron gun which generates a beam directed along a beam axis,
- a circuit of bunch-align-collect (BAC) tuned cavities that bunch the beam and amplify an RF signal,
- a collector where the beam is collected and dumped,
- a standard output cavity and waveguide coupled to a window to output RF power at a fundamental mode to an external load,
- additional bunch-align-collect (BAC) cavities tuned to a higher harmonic frequency, and
- a harmonic output waveguide coupled to the collect cavity of the additional BAC cavities and coupled to a window to output RF power at a harmonic mode to an additional external load,
- wherein the electron gun, the circuit of BAC tuned cavities, the standard output cavity, the additional BAC cavities, and the collector are all distinct components aligned along the beam axis.
