We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search bosonic dark matter across [10^{-3},1] eV ([0.24, 240] THz) mass range. BREAD proposes a cylindrical metal barrel convert into photons, which novel parabolic reflector focuses onto photosensor. unique geometry enables enclosure in standard cryostats high-field solenoids, overcoming limitations of current dish antennas. A pilot 0.7 m^{2} experiment...
We present first results from a dark photon matter search in the mass range 44 to 52 μeV (10.7-12.5 GHz) using room-temperature dish antenna setup called GigaBREAD. Dark converts ordinary photons on cylindrical metallic emission surface with area 0.5 m^{2} and is focused by novel parabolic reflector onto horn antenna. Signals are read out low-noise receiver system. A data taking run 24 days of does not show evidence for this range, excluding mixing parameters χ≳10^{-12} at 90% confidence...
We report the first result from a dark photon matter search in mass range 78.62 to 83.95 μeV/c^{2} with dielectric haloscope prototype for madmax (Magnetized Disc and Mirror Axion eXperiment). Putative photons would convert detectable within stack consisting of three sapphire disks mirror. The emitted power this system is received by an antenna successively digitized using low-noise receiver. No significant signal attributable has been observed above expected background. Assuming unpolarized...
We present the results from first axion-like particle search conducted using a dish antenna. The experiment was at room temperature and sensitive to particles in $44-52\,\mu\mathrm{eV}$ range ($10.7 - 12.5\,\mathrm{GHz}$). novel antenna geometry proposed by BREAD collaboration previously used conduct dark photon same mass range. To allow for sensitivity, placed $3.9\,\mathrm{T}$ solenoid magnet Argonne National Laboratory. In presence of magnetic field, matter converts photons conductive...
