All astrophysical and cosmological data now point convincingly to a large component of Cold Dark Matter (CDM) in the Universe, but a dark matter particle has yet to be directly detected. A well-motivated possible candidate is a light axion. Should axions constitute the dark matter of our Milky Way halo, they may be detected through their conversion into a narrow microwave signal by an apparatus consisting of a microwave cavity resonator permeated by a magnetic field. Using this concept the Axion Dark Matter eXperiment (ADMX) has performed a search for such axions within the mass range of a few micro-eV. Recently a smaller microwave cavity experiment was constructed called ADMX-HF (High Frequency), specifically to explore higher ranges of axion masses. ADMX-HF also serves as a test-bed for innovations in microwave cavity and amplifier technologies that could be migrated to the larger ADMX platform. ADMX-HF and ADMX operate as "one experiment, two sites", sharing expertise, technology, and data. This award will expand the collaboration to accelerate the construction of ADMX-HF as well as dramatically expand its initial capability.Broader Impacts: ADMX has proven to be a technology driver as components such as the SQUID amplifiers developed for ADMX are already being used for other purposes. Innovations to be developed by ADMX-HF have similarly broad potential. Both PI and Co-PI are committed educators with long experience in involving undergraduate students in their research and engaging the public. The research funded through this award will inform additional education and outreach initiatives with which they are involved.

现在，所有天体物理和宇宙学数据都令人信服地指向了宇宙中冷暗物质（CDM）的大部分，但是尚未直接检测到暗物质粒子。 动机良好的候选者是光轴。 如果轴构成了我们银河系光环的暗物质，则可以通过将其转换为狭窄的微波信号来检测到它们，该设备由磁场渗透的微波炉谐振器组成。 使用此概念，轴突暗物质实验（ADMX）在几个微EV的质量范围内进行了搜索。 最近，构建了一个较小的微波腔实验，称为ADMX-HF（高频），专门探索较高的轴突质量。 ADMX-HF还用作微波炉和放大器技术的创新测试床，可以迁移到较大的ADMX平台。 ADMX-HF和ADMX作为“一个实验，两个站点”，共享专业知识，技术和数据。 该奖项将扩大协作，以加速ADMX-HF的构建，并大大扩展其最初的能力。Boader的影响：ADMX已被证明是技术推动力，因为诸如为ADMX开发的Squid放大器之类的组件已经被用于其他目的。 ADMX-HF要开发的创新具有类似的广泛潜力。 PI和Co-Pi都是忠实的教育者，在参与研究并参与公众的本科生方面拥有悠久的经验。 通过该奖项资助的研究将为他们参与的其他教育和外展计划提供信息。
