First results from ADMX Experiment: Phase IIa

The Axion,a light pseudo-scalar particle predicted as a consequence of the Peccei-Quinn solution to the Strong CP problem, is a compelling dark matter candidate with a well predicted coupling to the photon. The Axion Dark Matter Experiment (ADMX) is a microwave cavity experiment that has recently completed a full system upgrade and begun a comprehensive search for dark matter axions. The sensitivity of the newly upgraded experiment will be discussed and early results will be shown.
