论文摘要
轴轴的存在是解决强大CP问题的独特解决方案，轴是暗物质中最有前途的候选者之一。通过铁轴（ISAI）研究太阳轴是作为补充的桌面实验准备的，以确认太阳轴心方案。从与轴突核子耦合相关的核转变中探测X射线发射是一种领先的方法。 ISAI使用最先进的硅探测器（称为XRPIX）在极低的低背景环境下搜索从57FE的第一个激发状态的单色14.4 keV X射线。我们重点介绍了科学目标，实验设计和ISAI的最新状态。
The existence of the axion is a unique solution for the strong CP problem, and the axion is one of the most promising candidates of the dark matter. Investigating Solar Axion by Iron-57 (ISAI) is being prepared as a complemented table-top experiment to confirm the solar axion scenario. Probing an X-ray emission from the nuclear transitions associated with the axion-nucleon coupling is a leading approach. ISAI searches for the monochromatic 14.4 keV X-ray from the first excited state of 57Fe using a state-of-the-art pixelized silicon detector, dubbed XRPIX, under an extremely low-background environment. We highlight scientific objectives, experimental design and the latest status of ISAI.
