• 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^<11> and the electric field strength up to 60 MV/m are presently attainable, microwaves with energy density up to 16 kJ/m^3 can be stored in a superconducting cavity. The stored energy can be released, in a short time, by changing mechanically the coupling factro between the cavity and a waveguide circuit. The technical possibilities are discussed in some 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 imcrowave pulses which are not available in usual microwave oscillators. We suggest that the RF 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.
