ABRACADABRA, A Search for Low-Mass Axion Dark Matter
ABRACADABRA is a proposed experiment to search for ultralight () axion dark matter. When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the magnetic field lines and oscillates at the axion Compton frequency. In the presence of axion dark matter, a large toroidal magnet will act like an oscillating current ring, whose induced magnetic flux can be measured by an external pickup loop inductively coupled to a SQUID magnetometer. Both broadband and resonant readout circuits are considered. ABRACADABRA is fielding a 10-cm prototype in 2017 with the intention of scaling to a 1 m experiment. The long term goal is to probe QCD axions at the GUT-scale
