We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program, which plans to search for bosonic dark matter. BREAD proposes a cylindrical metal barrel to convert dark matter into photons and focuses them onto a photosensor using a novel parabolic reflector design. By conducting a pilot 0.7 m(2) barrel experiment, BREAD is expected to surpass existing dark photon coupling constraints and improve sensitivity.
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 [10(-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/root Hz 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.
