Abstract
Microwave cavities have been deployed to search for bosonic dark matter candidates with masses of a few $\mu$eV. However, the sensitivity of these cavity detectors is limited by their volume, and the traditionally-employed half-wavelength cavities suffer from a significant volume reduction at higher masses. ADMX-Orpheus mitigates this issue by operating a tunable, dielectrically-loaded cavity at a higher-order mode, which allows the detection volume to remain large. The ADMX-Orpheus inaugural run excludes dark photon dark matter with kinetic mixing angle $\chi > 10^{-13}$ between 65.5 $\mu$eV (15.8 GHz) and 69.3 $\mu$eV (16.8GHz), marking the highest-frequency tunable microwave cavity dark matter search to date.
