论文摘要

Axion暗物质实验（ADMX）超低噪声卤体技术已使两项科学运行（1A和1B）成功完成，这些跑步（1A和1B）在$ 2.66 $至$ 3.1 $ $ $ $ $ $ $ $ $ $ EV质量范围内，带有Dine-Fischler-Sredchler-Srednicki-Zhitnisky（DFSZ）敏感性。 [1,2]。因此，它是迄今为止在此质量范围内的最敏感的轴心搜索实验。我们讨论了过去几年来实现这种灵敏度的技术进步，其中包括实施组件，例如最先进的量子限制放大器和稀释冰箱。此外，我们证明了在运行1A中使用频率可调节的微带超导超导量子干扰器（Squid）放大器（MSA）和Josephson参数放大器（JPA），以及在RUN 1B中，以及具有系统噪声温度表征的新分析工具。

Axion Dark Matter eXperiment (ADMX) ultra low noise haloscope technology has enabled the successful completion of two science runs (1A and 1B) that looked for dark matter axions in the $2.66$ to $3.1$ $μ$eV mass range with Dine-Fischler-Srednicki-Zhitnisky (DFSZ) sensitivity Ref. [1,2]. Therefore, it is the most sensitive axion search experiment to date in this mass range. We discuss the technological advances made in the last several years to achieve this sensitivity, which includes the implementation of components, such as state-of-the-art quantum limited amplifiers and a dilution refrigerator. Furthermore, we demonstrate the use of a frequency tunable Microstrip Superconducting Quantum Interference Device (SQUID) Amplifier (MSA), in Run 1A, and a Josephson Parametric Amplifier (JPA), in Run 1B, along with novel analysis tools that characterize the system noise temperature.
