Description
The BREAD Collaboration is establishing a program of broadband searches for terahertz axion dark matter. Its hallmark is a cylindrical metal barrel converting axions to photons, focused by a parabolic reflector to low-noise photosensors. Practically, this novel dish antenna geometry enables enclosure inside standard cryostats and high-field solenoidal magnets. BREAD plans to open multiple decades of unexplored coupling sensitivity across the meV to eV mass range that has long eluded resonant-cavity haloscopes. We present the BREAD conceptual design and science program towards large-scale experiment, proposed in Phys. Rev. Lett. 128 (2022) 131801, with recent R&D experimental progress towards dark photon pilots planned at Fermilab.
