论文摘要

轴突谐振相互作用检测实验（ARIADNE）是使用核磁共振（NMR）搜索QCD轴的协作努力，其中轴轴是一个脱糖隆斯坦源质量和极化氦气样品之间自旋依赖性力的介体。由于实验涉及对小磁化的精确测量，因此它依赖于用超导磁屏蔽限制普通磁噪声。除了屏蔽外，其他来源对噪声水平的适当表征至关重要。我们详细研究了一个这样的噪声源：钨源质量中的杂质和约翰逊噪声引起的磁噪声。

The Axion Resonant InterAction Detection Experiment (ARIADNE) is a collaborative effort to search for the QCD axion using nuclear magnetic resonance (NMR), where the axion acts as a mediator of spin-dependent forces between an unpolarized tungsten source mass and a sample of polarized helium-3 gas. Since the experiment involves precision measurement of a small magnetization, it relies on limiting ordinary magnetic noise with superconducting magnetic shielding. In addition to the shielding, proper characterization of the noise level from other sources is crucial. We investigate one such noise source in detail: the magnetic noise due to impurities and Johnson noise in the tungsten source mass.
