Title: First Results from a Microwave Cavity Axion Search at 24 μ eV

Abstract

In this paper, we report on the first results from a new microwave cavity search for dark matter axions with masses above 20 μ eV . We exclude axion models with two-photon coupling g a γ γ 2 × 10 - 14 GeV - 1 over the range 23.55 < m a < 24.0 μ eV . These results represent two important achievements. First, we have reached cosmologically relevant sensitivity an order of magnitude higher in mass than any existing limits. Second and finally, by incorporating a dilution refrigerator and Josephson parametric amplifier, we have demonstrated total noise approaching the standard quantum limit for the first time in an axion search.
