We report the results from a haloscope search for axion dark matter in the 3.3-4.2 µeV mass range. This search excludes the axion-photon coupling predicted by one of the benchmark models of "invisible" axion dark matter, the KSVZ model. This sensitivity is achieved using a large-volume cavity, a superconducting magnet, an ultra low noise Josephson parametric amplifier, and sub-Kelvin temperatures. The validity of our detection procedure is ensured by injecting and detecting blind synthetic axion signals.

“…The Axion Dark Matter eXperiment (ADMX) reached the sensitivity of KSVZ axions in the range 1.9 µeV − 3.3 µeV [70,71] assuming virialized axions composing the whole DM density DM = 0.45 GeV/cm 3 . The setup was improved by using SQUID amplifiers [72], and then reached the line of the DFSZ model [73,74]. The HAYSTAC experiment searched for heavier axions by operating a setup similar to the ADMX one but using a Josephson Parametric Amplifier (JPA), and achieving quantum limited sensitivity [75] and beyond [76].…”

Building instructions for a ferromagnetic axion haloscope

A ferromagnetic haloscope is a rf spin-magnetometer used for searching Dark Matter in the form of axions. A magnetic material is monitored searching for anomalous magnetization oscillations which can be induced by dark matter axions. To properly devise such instrument one first needs to understand the features of the searched-for signal, namely the effective rf field of dark matter axions Ba acting on electronic spins. Once the properties of Ba are defined, the design and test of the apparatus may start. The optimal sample is a narrow linewidth and high spin-density material such as Yttrium Iron Garnet (YIG), coupled to a microwave cavity with almost matched linewidth to collect the signal. The power in the resonator is collected with an antenna and amplified with a Josephson Parametric amplifier, a quantum-limited device which, however, adds most of the setup noise. The signal is further amplified with low noise HEMT and down-converted for storage with an heterodyne receiver. This work describes how to build such apparatus, with all the experimental details, the main issues one might face, and some solutions.

“…As for the dark-photon case considered in Ref. [59], our axion signal however does not arise from considering a human-engineered shielding box (as employed, e.g., in other axion searches such as resonant cavity experiments [36,[62][63][64][65][66] and LC circuits [37,61,67]); instead, in our mass range of interest, Nature provides us with a ready-made shield. As explained in Ref.…”
