Near-quantum-limited axion dark matter search with the ORGAN experiment around 26 $\mu$eV

Abstract

The latest result from the ORGAN experiment, an axion haloscope is presented. This iteration of the experiment operated at millikelvin temperatures using a flux-driven Josephson parametric amplifier for reduced noise, along with various other improvements over previous iterations. Covering the $25.45-26.27\mu \text{eV}$ ($6.15-6.35$ GHz) mass (frequency) range, this near-quantum limited phase of ORGAN employs a conducting rod resonator and a 7-T solenoidal magnet to place the most sensitive exclusion limits on axion-photon coupling in the range to date, with $|g_{a\gamma \gamma }|\gtrsim 2.8\times 10^{-13}$ at a 95\% confidence level.
