In this paper we investigate the effect of gravitational waves (GW) on a superconductor. We find that the key properties of a superconductor, namely zero resistance and perfect diamagnetism, give rise to an important new effect, the presence of an induced electric fieldE(r, t) in the interior of the superconductor. TheE field reacts with the ions and superelectrons. We argue, that not only is the finding of the coupled interactions of gravitation, electromagnetism and superconductivity inherently interesting, but that the inducedE field might provide a significantly more sensitive means of detecting gravitational waves. It appears likely that existing resonant-mass superconducting antennas withL ∼- 3m,Q ∼- 108 could be readily modified to detectE fields induced by GWs of dimensionless amplitudeh ∼- 10−24
