Superconducting cavities can operate analogously to Weber bar detectors of gravitational waves, converting mechanical to electromagnetic energy. The significantly reduced electromagnetic noise results in increased sensitivity to high-frequency signals well outside the bandwidth of the lowest mechanical resonance. In this talk, we will briefly discuss such signals of gravitational waves and demonstrate that a setup similar to the existing “MAGO” prototype, operating in a scanning or broadband manner, could have sensitivity to strains approximately 10^-22 - 10^-18 for frequencies of approximately 10 kHz - 1 GHz.
