概述了我们的实验计划，以寻找轴子和类轴子粒子（ALP）的暗物质，使用核磁共振（NMR）技术。一个振荡的轴子场可以直接或通过产生一个振荡的核电偶极矩（EDM）对核自旋施加一个随时间变化的扭矩。磁共振技术可用于检测这种效应。第一代实验探索了几十年的ALP参数空间，超出了目前的天体物理和实验室的界限。预计未来的实验版本将对与具有质量的量子色动力学（QCD）相关的轴子敏感。
An overview of our experimental program to search for axion and axion-like-particle (ALP) dark matter using nuclear magnetic resonance (NMR) techniques is presented. An oscillating axion field can exert a time-varying torque on nuclear spins either directly or via generation of an oscillating nuclear electric dipole moment (EDM). Magnetic resonance techniques can be used to detect such an effect. The first-generation experiments explore many decades of ALP parameter space beyond the current astrophysical and laboratory bounds. It is anticipated that future versions of the experiments will be sensitive to the axions associated with quantum chromodynamics (QCD) having masses.
