“…The best performances of currently running axion experiments were achieved with quantum-limited devices, such as superconducting quantum interference devices (SQUIDs) and Josephson parametric amplifiers (JPAs) [17][18][19]26,47], but efforts have been put toward counting single photons from axion interactions [42,46,48,49]. The reason is clear from [50]: working at higher frequencies while having a good scan rate at the same time requires single photon counters, which have better noise performances with respect to linear amplifiers above about 10 GHz.…”

“…The most exploited detection principle of axions and ALPs is the haloscope proposed by Sikivie [14,15], whose description is addressed in a review: [16]. Examples of running experiments, also shown by the vertical lines in Figure 1, are ADMX [17,18], HAYSTAC [19], CAPP-8T [20], CAPP-9T [21], ORGAN [22], and QUAX [23][24][25][26]; other proposed experiments include RADES [27,28], MADMAX [29], BRASS [30], and KLASH [31][32][33].…”

Detection of light dark matter, such as axion-like particles, puts stringent requirements on the efficiency and dark-count rates of microwave-photon detectors. The possibility of operating a current-biased Josephson junction as a single-microwave photon-detector was investigated through numerical simulations, and through an initial characterization of two Al junctions fabricated by shadow mask evaporation, done in a dilution refrigerator by measuring escape currents at different temperatures, from 40 mK up to the Al transition temperature. The escape dynamics of the junctions were reproduced in the simulation, including the dissipative effects. Inhibition of thermal activation was observed, leaving the macroscopic quantum tunneling as the dominant effect well beyond the crossover temperature.

“…Figure 9 shows the result of this analysis in the context of other haloscope searches: CAST-RADES places a competitive limit at an axion mass above the highest ADMX-Sidecar limit [45] and slightly lower than the QUAX results [34,35].…”

“…This technology can thus, in principle, take advantage of the large volume offered by dipole magnets in order to increase the sensitivity to the axion. Other groups are developing complementary techniques [32,33] or performed searches at higher masses using new cavity geometries [34][35][36][37], but at 34.67 µeV the best limit so far was placed by CAST's solar axion searches [30].…”

We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67 μeV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. An exclusion limit with a 95% credibility level on the axion-photon coupling constant of gaγ ≳ 4 × 10−13 GeV−1 over a mass range of 34.6738 μeV < ma< 34.6771 μeV is set. This constitutes a significant improvement over the current strongest limit set by CAST at this mass and is at the same time one of the most sensitive direct searches for an axion dark matter candidate above the mass of 25 μeV. The results also demonstrate the feasibility of exploring a wider mass range around the value probed by CAST-RADES in this work using similar coherent resonant cavities.

Axions are a well‐motivated dark matter candidate, with a host of experiments around the world searching for direct evidence of their existence. The ORGAN Experiment is a type of axion detector known as an axion haloscope, which takes the form of a cryogenic resonant cavity embedded in a strong magnetic field. ORGAN recently completed Phase 1a, a scan for axions ≈65 µeV, and placed the most stringent limits to date on the dark matter axion–photon coupling in this region, . It has been shown that axion haloscopes such as ORGAN are automatically sensitive to other kinds of dark matter candidates, such as dark photons, scalar field/dilaton dark matter, and exotic axion–electromagnetic couplings motivated by quantum electromagnetodynamics. The exclusion limits placed on these various dark matter candidates are computed by ORGAN 1a, and sensitivity for some future ORGAN phases are projected. In particular, the dark photon limits are the most sensitive to date in some regions of the parameter space.
