"Status of the Hunt for Dark Matter with the ADMX Experiment"

Gianpaolo Carosi , Lawrence Livermore National Lab
[Host: Craig Group]

The axion is a hypothetical particle that may solve two problems in particle physics & cosmology, the Strong-CP problem and the nature of dark matter. The Axion Dark Matter Experiment (ADMX) is the DOE Flagship search for these particles as part of the “Generation-2” direct dark matter search program in High Energy Physics. The experiment uses a tunable resonant cavity in a large static magnetic field to enhance the conversion of axions to detectable microwaves. Quantum-limited amplifiers based on superconducting Josephson Junction circuits are critical to allow the search to be sensitive enough to rapidly scan the frequencies where the axion may exist.  Here I will describe the status of the search along with an update on the planning and prototyping for the next phase of ADMX.”
