Description
The experiments in the DMRadio program are designed to search for low mass sub-μeV axion dark matter using the coupling of axions to photons. Specifically, DMRadio-m$^3$ is designed to have sensitivity to KSVZ and DFSZ QCD axions in the 40-830 neV (10-200 MHz) range. A dc solenoidal magnetic field sources an axion current inside a coaxial pickup structure whose resonance frequency is tuned using lumped tuning elements. In this talk, we present the sensitivity of DMRadio-m$^3$. The primary science goal of sensitivity to DFSZ axions across 30–200 MHz can be achieved with a 3$\sigma$ live scan time of 3.7 years. This is informed by extensive finite element electromagnetic modeling of the pickup structure of the system, which will also be presented.
