Description
The axion is one of the most compelling dark matter (DM) candidates and a solution to the strong charge-parity problem. The DMRadio program consists of three experiments that together search for axions in the range 5 kHz - 200 MHz (20 peV - 0.8 $\mu$eV) with sensitivity to the DFSZ axion model: DMRadio-50L, DMRadio-m$^3$, and DMRadio-GUT. DMRadio-50L is a resonant lumped-element detector with a toroidal magnet searching for axions in the range 5 kHz - 5 MHz (20 peV - 20 neV) with a target sensitivity to axion-photon-photon coupling $5 \times 10^{-15}$ GeV$^{-1}$. DMRadio-50L also acts as an innovation platform and technology test bed for quantum sensors that will enable a next-generation search for GUT-scale axions in this mass region (DMRadio-GUT). This talk will provide an overview and status update of the DMRadio-50L experiment.
DMRadio-50L is supported by the Gordon and Betty Moore foundation and the Heising-Simons foundation. Quantum sensing work is supported under the DOE QuantISED program, and further support is provided by DOE and NSF grants to individual institutions.
