论文摘要
QCD轴轴是解释宇宙深色物质的最引人注目的候选者之一。凭借其极小的质量（$ \ ll 1 \，\ mathrm {ev}/c^2 $），Axion暗物质作为经典字段而不是粒子相互作用。它与光子与光子的耦合会导致对麦克斯韦方程的修改，该方程可以通过非常敏感的读数电路进行测量。 dmradio-m $^3 $是使用$> 4 $ t静态磁场，同轴电感拾音器，可调LC谐振器和DC-Squid读数的下一代搜索$ 1 \，μ$ eV以下的轴线暗物质的下一代搜索。它旨在在$ 20 \，\ mathrm {nev} \ sillesim m_ac^2 \ lyseSim 800 \，\ mathrm {nev} $（$ 5 \，\ Mathrm {mhz} <200 \ 200 \，\，\，\，\，\ m m i} $）上搜索QCD Axion暗物质。主要的科学目标旨在实现$ M_AC^2 \以上的DFSZ敏感性，大约120 $ nev（30 MHz），其二级科学目标是将KSVZ轴探测至$ M_AC^2 \ oft40 \，\ Mathrm {nev} $（10 MHz）。
The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass ($\ll 1\,\mathrm{eV}/c^2$), axion dark matter interacts as a classical field rather than a particle. Its coupling to photons leads to a modification of Maxwell's equations that can be measured with extremely sensitive readout circuits. DMRadio-m$^3$ is a next-generation search for axion dark matter below $1\,μ$eV using a $>4$ T static magnetic field, a coaxial inductive pickup, a tunable LC resonator, and a DC-SQUID readout. It is designed to search for QCD axion dark matter over the range $20\,\mathrm{neV}\lesssim m_ac^2\lesssim 800\,\mathrm{neV}$ ($5\,\mathrm{MHz}<ν<200\,\mathrm{MHz}$). The primary science goal aims to achieve DFSZ sensitivity above $m_ac^2\approx 120$ neV (30 MHz), with a secondary science goal of probing KSVZ axions down to $m_ac^2\approx40\,\mathrm{neV}$ (10 MHz).
