Abstract

Recent theoretical advancements have made the QCD axion a stronger dark matter candidate, especially in the sub-μeV\mu\text{eV} range. While cavity haloscopes have made significant progress in excluding QCD axions in the 1100 μeV1 - 100\ \mu\text{eV} region, the 1 peV1 μeV1 \text{ peV} - 1\ \mu\text{eV} region remains unexplored. The DMRadio program consists of a series of experiments designed to probe low mass axions. DMRadio-50L uses a 1 T average field toroidal magnet and a high-Q LC-oscillator with target sensitivity to axions of gaγγ<5×1015 GeV1g_{a\gamma\gamma} <5\times10^{-15}\text{ GeV}^{-1} between 5 kHz and 5 MHz. DMRadio-m3^3 consists of a higher frequency LC-oscillator in a 4 T peak field solenoidal magnet with sensitivity to the DFSZ model of QCD axions between 30 MHz and 200 MHz. In this work, we present the status of DMRadio-50L and DMRadio-m3^3.
