DEEPDISH: A Dark Matter Haloscope Using MKIDs

We describe a pathfinder experiment named DEEPDISH (dark matter extended energy probe: dielectric infrared superconducting haloscope) to search unexplored regions of dark matter (DM) parameter space: first for dark photon DM and later for axion DM with the application of a magnetic field. The DM would convert to photons within an optical stack and subsequently be detected by a microwave kinetic inductance detector (MKID) array.
