利用Haystac实验的压缩态接收器，对质量为10 ev/c的暗物质轴子进行了搜索，获得了亚量子限幅噪声。这份报告详细介绍了以前用来搜索质量范围为16.96-17.12美元和17.14-17.28美元的轴子的实验的设计和操作细节。这些升级包括对数据采集程序的改进，将有效停滞时间减少了5倍，使扫描新区域的速度提高了1.6倍，并具有相当的灵敏度。在$18.44-18.71 eV/c^{2}$($4.459-4.523$GHz)范围内没有发现显著的轴子信号证据，导致轴子-光子耦合的总上限排除在$90\$水平。
A search for dark matter axions with masses $>10 \mu eV/c^{2}$ has been performed using the HAYSTAC experiment's squeezed state receiver to achieve sub-quantum limited noise. This report includes details of the design and operation of the experiment previously used to search for axions in the mass ranges $16.96-17.12$ and $17.14-17.28 \mu eV/c^{2}$($4.100-4.140$GHz) and $4.145-4.178$GHz) as well as upgrades to facilitate an extended search at higher masses. These upgrades include improvements to the data acquisition routine which have reduced the effective dead time by a factor of 5, allowing for the new region to be scanned $\sim$1.6 times faster with comparable sensitivity. No statistically significant evidence of an axion signal is found in the range $18.44-18.71\mu eV/c^{2}$($4.459-4.523$GHz), leading to an aggregate upper limit exclusion at the $90\%$ level on the axion-photon coupling of $2.06\times g_{\gamma}^{KSVZ}$.
