Abstract
A microwave pulse power switching system comprised of a pulse power switcher and a microwave circulator is interposable between a pulse power source and a pulse power receiver such as an accelerator. The pulse power switcher and microwave circulator are configured to allow switching of the pulse power delivered to the pulse power receiver while isolating the pulse power receiver from the pulse power source.

A microwave pulse power switching system interposable between a pulse power source and a pulse power receiver which receives and uses pulse power produced by the pulse power source for a useful purpose, the system comprising:
- a pulse power switcher having a pulse power switcher input port, a pulse power switcher output port and a forward wave pulse power diversion port, the pulse power switcher being configured such that all or a portion of the power of individual pulses within a series of microwave pulses entering the pulse power switcher input port of the pulse power switcher can be switchably diverted through the forward wave pulse power diversion port of the pulse power switcher to any load for controlling the power of the microwave pulses exiting the pulse power switcher output port, and
- a waveguide circulator having a circulator pulse power input port, a circulator pulse power circulator output port and a return microwave diversion port configured to divert microwave power returned by the pulse power receiver to any load,
- the pulse power switcher and waveguide circulator being connected in series such that the pulse power switcher controls the amount of microwave power within each microwave pulse of a series of microwave pulses that is delivered to the pulse power receiver through the series connected pulse power switcher and waveguide circulator, and wherein the waveguide circulator receives and diverts microwave power returned by a pulse power receiver to substantially prevent the returned microwave power from arriving at the pulse power source.
A microwave pulse power switching system interposable between a pulse power source and a pulse power receiver which receives and uses pulse power produced by the pulse power source for a useful purpose, comprising:
- a 3-port pulse power switcher having a pulse power switcher input port, a pulse power switcher output port, and a switcher forward wave pulse power diversion port, the pulse power switcher being configured such that all or a portion of the power of individual pulses within a series of microwave pulses entering the pulse power input port of the 3-port pulse power switcher can be switchably diverted through the forward wave pulse power diversion port of the pulse power switcher to any load for controlling of the microwave pulses exiting the pulse power output port of the pulse power switcher, and
- a 3-port waveguide circulator having a circulator pulse power input port, a circulator pulse power output port and a return microwave diversion port configured to divert microwave power returned by the pulse power receiver to any load,
- the waveguide circulator being connected to the pulse power switcher such that the microwave circulator is positioned between the pulse power switcher and the pulse power receiver such that the pulse power switcher controls the amount of microwave power within each microwave pulse of a series of microwave pulses that is delivered to the pulse power receiver through the connected pulse power switcher and pulse power circulator, and wherein the waveguide circulator receives and diverts microwave power returned by a pulse power receiver before the returned microwave power reaches the pulse power switcher.
A microwave pulse power switching system interposable between a pulse power source and a pulse power receiver which receives and uses pulse power produced by the pulse power source for a useful purpose, comprising:
- a 4-port pulse power switcher having a pulse power switcher input port, a pulse power switcher output port, a switcher forward wave pulse power diversion port for switchably diverting forward wave pulse power to any load, and a switcher return power diversion port for diverting at least a portion of the microwave power returned by the pulse power receiver to any load, the pulse power switcher being configured such that all or a portion of the power of individual pulses within a series of microwave pulses entering the pulse power input port of the four-port pulse power switcher can be switchably diverted through the forward wave pulse power diversion port of the four-port pulse power switcher to any load for controlling the power of the microwave pulses exiting the pulse power output port of the pulse power switcher, and
- a 3-port waveguide circulator having a circulator pulse power input port, a circulator pulse power output port, and a circulator return microwave diversion port configured to divert microwave power returned by the pulse power receiver to any load,
- the waveguide circulator being connected to the pulse power switcher such that the microwave circulator is positioned between the pulse power switcher and the pulse power source such that the pulse power switcher controls the amount of microwave power within each microwave pulse of the series of microwave pulses that is delivered to the pulse power receiver through the connected pulse power switcher and pulse power circulator, and wherein the waveguide circulator receives and diverts microwave power returned by a pulse power receiver that is not diverted by the 4-port switcher through the return microwave diversion port thereof.
A microwave pulse power switching system interposable between a pulse power source and a pulse power receiver which receives and uses pulse power produced by the pulse power source for a useful purpose, comprising:
- a pulse power switcher for switchably controlling the magnitude of the power in the pulses in a series of microwave pulses delivered to a pulse power receiver from the pulse power source, and
- an isolator connector in series with the pulse power switcher to isolate the pulse power source from the pulse power receiver with respect to microwave power returned by the pulse power receiver.
A method for isolating a pulse power source from a reflective load which receives and uses pulse power produced by the pulse power source for a useful purpose, comprised of passing pulse power generated by the pulse power source through a pulse power switcher and a waveguide circulator that are connected in series, the pulse power switcher and waveguide circulator being configured such that the amount of pulse power delivered to the pulse power receiver is controlled by the pulse power switcher and at least a portion of the pulse power reflected by the reflective load is diverted to any load by the waveguide circulator.
