摘要
DMRadio-m是一项旨在对 10–200 MHz（41 neV – 0.83 eV/）范围内的 KSVZ 和 DFSZ QCD 轴子模型具有灵敏度的实验。该实验利用螺线管直流磁场将轴子暗物质信号转换为同轴铜拾取器中的交流电磁响应。由该轴子信号感生的电流由直流 SQUID 测量。在这项工作中，我们给出了 DMRadio-m 全频段上对轴子信号响应的电磁建模，该频段从低频集总元件极限一直延伸到轴子康普顿波长仅比探测器尺寸大两倍的 regime。基于这些结果，我们确定了实验的活时间与灵敏度。对 30–200 MHz 范围内 DFSZ 轴子的灵敏度这一主要科学目标，可通过 2.9 年的 活扫描时间实现。
