Abstract: SRF properties are inherently a surface phenomenon involving a material thickness of a few microns thus opening up the possibility of using thin film coatings to achieve a desired performance. I will describe our experimental attempts to test the superconducting/insulating/superconducting (SIS) multilayer model proposed by A. Gurevich  to shield the bulk of the cavity from vortex penetration and hence enable larger accelerating fields than presently possible.
