Overview of the Axion Dark Matter eXperiment (ADMX)

The nature of dark matter is one of the greatest mysteries in particle physics and cosmology. The axion, a light neutral boson predicted as a solution to the strong CP problem in QCD, is also a compelling dark matter candidate. The Axion Dark Matter Experiment (ADMX) uses the haloscope technique to search for dark matter axions resonantly converting to detectable microwaves in a microwave cavity threaded by a strong magnetic field. ADMX has been on the forefront of the search for dark matter axions for the last 20+ years and its recent upgrades have given it exquisite sensitivity enabling it to cover the entire range of potential axion couplings for the first time. In this talk I will introduce the axion as a dark matter candidate, discuss the ADMX experimental technique and outline the recent results and future plans for ADMX.
