论文摘要
我们描述了一个新的台式静电储存环概念，价格为$ 30 $ kev二极化离子在冷冻旋转状态下。该设备最终将能够用sub-MHz带宽的10 $^{-21} $ t分辨率测量磁场。有可能存储不同种类的离子或离子分子，并使用激光器和鱿鱼准备和探测系统的态度，因此可以用于搜索电子和核子的电偶极矩（EDM），以及轴突样粒子粒子暗物质和暗光子暗物质。它的敏感性潜力源于几个小时的存储时间，相当长的自旋连贯性时间，并且可能会捕获高达10 $^9 $的颗粒，其中可能有不同的状态制备以进行差异测量。作为一个暗物质实验，它在10 $^{ - 10} $至10 $^{ - 19} $ eV的质量范围内最敏感，它可以在其中探测低于当前和拟议的实验室实验的数量级。
We describe a new table-top electrostatic storage ring concept for $30$ keV polarized ions at frozen spin condition. The device will ultimately be capable of measuring magnetic fields with a resolution of 10$^{-21}$ T with sub-mHz bandwidth. With the possibility to store different kinds of ions or ionic molecules and access to prepare and probe states of the systems using lasers and SQUIDs, it can be used to search for electric dipole moments (EDMs) of electrons and nucleons, as well as axion-like particle dark matter and dark photon dark matter. Its sensitivity potential stems from several hours of storage time, comparably long spin coherence times, and the possibility to trap up to 10$^9$ particles in bunches with possibly different state preparations for differential measurements. As a dark matter experiment, it is most sensitive in the mass range of 10$^{-10}$ to 10$^{-19}$ eV, where it can potentially probe couplings orders of magnitude below current and proposed laboratory experiments.
