轴子共振相互作用探测实验(ARIADNE)是一个基于核磁共振的实验,将寻找非极化源质量转子和附近自旋极化核之间的新型轴子诱导自旋相关相互作用。为了检测亚阿特斯拉水平上微弱的轴子介导信号,该实验依赖于超低的磁场背景和噪声。我们测量和表征的磁场从一个原型钨转子。我们表明,该领域主要是由几个离散的磁偶极子,可能是由于转子中的杂质。这是通过适合每个偶极子的位置和磁矩的数值优化管道完成的。我们发现,在当前的退磁过程中,杂质的磁矩限制在A。我们进一步表明,屏蔽因子将支持ARIADNE的设计灵敏度与当前水平的钨纯度和退磁过程。
The Axion Resonant Interaction Detection Experiment (ARIADNE) is a nuclear-magnetic-resonance-based experiment that will search for novel axion-induced spin-dependent interactions between an unpolarized source mass rotor and spin-polarizednuclei placed nearby. To detect a feeble axion-mediated signal at the subattotesla level, the experiment relies on ultralow magnetic background and noise. We measure and characterize the magnetic field from a prototype tungsten rotor. We show that the field is dominantly caused by a few discrete magnetic dipoles, likely due to impurities in the rotor. This is done via a numerical optimization pipeline which fits for the locations and magnetic moments of each dipole. We find that under the current demagnetization procedure, the magnetic moment of the impurities is bounded atA. We further show that a shielding factor ofwill support ARIADNE's design sensitivity with the current level of tungsten purity and demagnetization process.
