AI 中文摘要
轴子暗物质晕探测器搜寻的主要挑战之一是一种无损耗调谐机制，该机制需能覆盖探测器中心频率附近的显著频率范围。本文报告了一款名为VORTEX（Vertical-cut Optimised Resonant Tunable cavity for dark matter EXploration，即用于暗物质探测的垂直切割优化谐振可调腔）的轴子晕探测器的实现与性能，其中心频率为8.5 GHz，调谐范围约800 MHz。该装置在毫开尔文温度下测量性能并与模拟结果对比，还通过“珠拉法”直接测试该类型腔的腔模结构，观察到与预期的良好吻合。该装置将用于即将开展的RADES（Relic Axion Detection Exploratory Setup，即遗迹轴子探测探索装置）数据采集活动，该活动采用12 T螺线管磁铁。
英文摘要
One of the major challenges in axion dark matter haloscope searches is a loss-less tuning mechanism that is able to cover a significant frequency range around the haloscope's central frequency. In this article, we report on the implementation and performance of an axion haloscope dubbed Vertical-cut Optimised Resonant Tunable cavity for dark matter EXploration (VORTEX) centred at $8.5$ GHz with a tuning range of around $800$ MHz. The performance of this setup is measured at temperatures in the mK range and compared to simulation. In addition, we test the cavity-mode structure of this cavity type directly via the `bead-pull method' and observe satisfactory agreement with expectations. The arrangement is poised to be used in an upcoming RADES (Relic Axion Detection Exploratory Setup) data-taking campaign employing a $12$ T solenoid magnet.
