Recent results and R&D of the Generation-2 Axion Dark Matter Experiment
POSTER
Abstract
The Axion Dark Matter eXperiment (ADMX) is a search for the dark matter axion. The axion, if discovered, solves both the strong CP problem and the dark matter problem. ADMX seeks to detect axions by the resonant conversion of axions into microwave photons in a high Q cavity in the presence of a strong magnetic field. Because the expected signal is of yocto-watt order, Generation-2 ADMX (G2) employs a dilution refrigerator and quantum noise limited SQUID amplifiers to achieve its necessary sub-kelvin cavity temperature and low noise sensitivity. This poster highlights axion exclusion limits from previous runs, future run plans, and the R&D work to achieve them.
