Proposed high-power microwave source using a superconducting cavity as an energy storage
A new principle of a high-power microwave source using a superconducting cavity as an energy storage is proposed. Since the quality factors about 10 to the 11th power and the electric field strength up to 60 MV/m are presently attainable, microwaves with energy density up to 0.016J/cum can be stored in a superconducting cavity. The stored energy can be released, in a short time, by changing mechanically the coupling factor between the cavity and a waveguide circuit. The technical possibilities are discussed in Rome detail. It is emphasized that, although the economical feasibilities are not assured at this stage of technology, this energy storage can be used to produce high-power microwave pulses which are not available in usual microwave oscillators. The resonant frequency energy storage presented here can be applied to the experiments in nuclear fusion research, because it is suited to a long-pulse operation of the order of 1 msec with an output power greater than 10 MW.
