PXS - A New Search for ueV-Scale Axions

Learn about PXS, a groundbreaking axion search experiment designed to detect dark matter candidates in the 200–500 MHz frequency band (0.8–2 ueV mass range) in this conference talk by Lyman Page. Discover how this innovative experiment bridges the gap between existing axion detection programs by operating in the transitional mass range between the Axion Dark Matter eXperiment and the Dark Matter Radio program. Explore the three core technological components that make PXS possible: a new 5 Tesla conduction-cooled NbTi magnet developed by Yuhu Zhai's group at Princeton Plasma Physics Laboratory, an ultra-low temperature resonator and readout system operating below 50 mK developed at Princeton University, and quantum-noise limited amplifiers created by Peter Day's team at the Jet Propulsion Laboratory. Understand how axions represent both an exciting dark matter candidate and a potential solution to the strong CP problem in particle physics. Gain insights into the recent technological advances that enable this ambitious small-scale experimental project and learn about the integration strategy for combining these cutting-edge components into a functional detection system capable of probing previously unexplored parameter space in the search for axion dark matter.
