The axion is a hypothetical elementary particle and cold dark matter candidate. In this RF cavity experiment, halo axions entering a resonant cavity immersed in a static magnetic field convert into microwave photons, with the resulting photons detected by a low-noise receiver. The ADMX Collaboration presents new limits on the axion-to-photon coupling and local axion dark matter halo mass density from a RF cavity axion search in the axion mass range 1.9-2.3 {micro}eV, broadening the search range…

SQUID-based microwave cavity search for dark-matter axions.
TLDR
The first result from such an axion search using a superconducting first-stage amplifier (SQUID) replacing a conventional GaAs field-effect transistor amplifier is reported, setting the stage for a definitive axions search utilizing near quantum-limited SQUID amplifiers.
Search for Invisible Axion Dark Matter with the Axion Dark Matter Experiment.
TLDR
This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81  μeV, achieving unprecedented sensitivity by operating a large-volume haloscope at subkelvin temperatures, thereby reducing thermal noise as well as the excess noise from the ultralow-noise superconducting quantum interference device amplifier used for the signal power readout.
First Results from a Microwave Cavity Axion Search at 24  μeV.
TLDR
By incorporating a dilution refrigerator and Josephson parametric amplifier, this work has demonstrated total noise approaching the standard quantum limit for the first time in an axion search and reached cosmologically relevant sensitivity an order of magnitude higher in mass than any existing limits.
Searches for Astrophysical and Cosmological Axions
▪ Abstract The axion, a favored dark matter candidate, is expected to have a very small mass and extraordinarily weak couplings. Although it has eluded discovery or exclusion for three decades, it

Limits on axion–photon coupling or on local axion density: Dependence on models of the Milky Way’s dark halo
Abstract The μ eV-scale axion is a compelling cold dark matter candidate. The Axion Dark Matter eXperiment (ADMX) searches for axions by stimulating the decay of galactic dark matter halo axions into
Searches for Astrophysical and Dark Matter Axions
We describe two on-going experiments to detect axions, light pseudoscalar particles which arise from the Peccei-Quinn solution to the Strong-CP problem. The Axion Dark Matter Experiment (ADMX) has
Direct detection of dark matter axions with directional sensitivity
We study the directional effect of the expected axion dark matter signal in a resonant cavity of an axion haloscope detector, for cavity geometries not satisfying the condition that the axion de
