Description

DMRadio, which now includes the ABRACADABRA collaboration, is a multi-detector program to search for axion dark matter (aDM) with mass below 1 𝜇eV using a lumped-element resonator. DMRadio-50L is a toroidal detector that will probe aDM over the range 20 peV$<m_a<$ 20 neV down to photon couplings of $g_{a\gamma \gamma }>5\times {10}^{-15}{\mathrm{GeV}}^{-1}$. It is currently under construction and will also serve as a testbed for acceleration with quantum sensors. DMRadio-m3, which is in the design phase, will have a larger magnet and be sensitive to aDM in the QCD axion band from 20 neV $<m_a<$ 0.8 𝜇eV. We are also pursuing the development of a future search for GUT-scale QCD axions with masses down to 1 neV, called DMRadio-GUT. In this talk I will give an overview of the DMRadio program, design considerations, and schedule. I will also present recent results from ABRACADABRA.
