AI 中文摘要
若自旋透明存储环成为粒子自旋进动测量实验的常用工具，将为基础物理实验带来突破性进展。本文提出一种新型的高度专业化桌级存储环设计，其采用低能极化电子束与莫特极化测量技术。基于自旋透明假设，电子沿存储环周期性轨道运行时，其磁偶极矩引发的自旋进动可在任意束流能量下被抵消；而由感兴趣的基础物理过程诱导的自旋进动，例如电子的永久电偶极矩（EDM）以及轴子等超轻暗物质介导的力，则会不断累积。这类存储环不仅适用于测量与CP破坏、宇宙物质-反物质不对称性相关的EDM和轴子搜索，还可能在量子计算领域展现出极具前景的应用。
英文摘要
A breakthrough in fundamental physics experiments measuring particle spin precession may happen if spin-transparent storage rings become adopted tools for such experiments. We present a new design of highly specialized table-sized storage rings, which use low-energy polarized electron beams and Mott polarimetry. Based on the spin transparency ansatz, the spin precession stemming from the magnetic dipole moment is canceled at any beam energy after an electron's turn along the periodic orbit in the ring. Meanwhile, a spin precession induced by the fundamental physics of interest, e.g., the electron's permanent electric dipole moment (EDM) and/or ultralight-dark-matter-mediated forces such as axions, will accumulate. However, capitalizing on such types of rings is not only desirable for measurements of EDMs and axion searches relevant to $CP$ violation and matter-antimatter asymmetry in the Universe, but may also find very promising applications in quantum computing.
