Overview/Status of the DM Radio 50 L Experiment

Axions are a well-motivated dark matter candidate, which currently have a wide open and accessible parameter space, with few constraints on their mass and coupling strength to photons. The DM Radio-50L experiment seeks to explore a wide portion of this axion parameter space (between 5 kHz - 5 MHz), taking advantage of lumped element high-Q resonators with optimal out-of-band sensitivity. DM Radio-50L will utilize a torrorial magnet with a field strength of at least 100 mT, with a design sensitivity goal of reaching at least $g_{a\gamma\gamma}\sim 5 \times 10^{-15}\,\mathrm{GeV^{-1}}$ across the entire region of interest. At the same time, the lessons learned from the construction of this experiment will inform the design of the future DM Radio-$m^3$ experiment. In this talk, we will present an overview of the current status of the DM Radio-50L experiment as well as current efforts to optimize the design in order to reach the above science goals.
