摘要

利用HAYSTAC实验的压缩态接收机实现了亚量子极限噪声,对质量>10μeV/c2>10 \mu eV/c^{2}的暗物质轴子进行了搜寻。本报告包含先前用于搜寻质量范围16.9617.1216.96-17.1217.1417.28μeV/c217.14-17.28 \mu eV/c^{2}4.1004.1404.100-4.140GHz)及4.1454.1784.145-4.178GHz)内轴子的实验设计与运行细节,以及为在更高质量处扩展搜寻所做的升级。这些升级包括改进数据采集例程,将有效死时间降低了5倍,使得新区域能以约1.6倍速度扫描且灵敏度相当。在18.4418.71μeV/c218.44-18.71\mu eV/c^{2}4.4594.5234.459-4.523GHz)范围内未发现统计显著的轴子信号证据,从而在90%90\%置信水平上给出轴子-光子耦合2.06×gγKSVZ2.06\times g_{\gamma}^{KSVZ}的聚合排除上限。
