“…Figure 1 (d) shows the diffraction-limited electromagnetic fields at the focal plane. The electric field polarized along the radial direction can be picked up by coaxial horn antennas [86,87]. Receiver designs based on microwave and submillimeter astronomy projects could be considered for signal collection.…”

We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search for bosonic dark matter across the ½10 −3 ; 1 eV ([0.24, 240] THz) mass range. BREAD proposes a cylindrical metal barrel to convert dark matter into photons, which a novel parabolic reflector design focuses onto a photosensor. This unique geometry enables enclosure in standard cryostats and high-field solenoids, overcoming limitations of current dish antennas. A pilot 0.7 m 2 barrel experiment planned at Fermilab is projected to surpass existing dark photon coupling constraints by over a decade with one-day runtime. Axion sensitivity requires < 10 −20 W= ffiffiffiffiffiffi Hz p sensor noise equivalent power with a 10 T solenoid and 10 m 2 barrel. We project BREAD sensitivity for various sensor technologies and discuss future prospects.
