Description
I will report on the first results from a new search for
axion dark matter using a microwave cavity detector at ~5
GHz frequencies. This detector has achieved
near-quantum-limited sensitivity using a dilution
refrigerator and a Josephson parametric amplifier, and
excluded axion-photon-photon couplings a factor of 2.3 above
the benchmark KSVZ model in the mass range 23.55 micro-eV< m
<24.0 micro-eV. These are the first limits within the QCD axion
model band in the mass decade above 10 micro-eV.
