Status of and results from the QUALIPHIDE wave-like dark matter experimental program
ORAL
Abstract
A bevy of recent theoretical work suggests that dark matter may consist of O(10) ueV mass "post-inflationary" axions or hidden photons . The Quantum Limited Photons In The Dark Experiment (QUALIPHIDE) is an R&D testbed program aimed at developing superconducting sensor and amplifier technology to aid in the detection of such dark matter candidates, for eventual integration into larger searches. To source the dark matter signal QUALIPHIDE presently exploits the conversion of hidden photon dark matter into conventional photons on conductive and reflective surfaces. Given a suitable geometry, these photons are concentrated on a detector at the focal point of the reflective surface for eventual readout and amplification. We discuss the status of and results from two variants of QUALIPHIDE, spanning either 20-80 ueV (i.e. 5-20 GHz frequency) or the neighborhood of 50 meV (12 THz). These particular experiments exploit novel superconducting based wideband traveling wave parametric amplifiers or kinetic inductance detectors and will demonstrate the effectiveness of using these RF technologies for fundamental physics applications.
