Abstract: The QCD axion is a well-motivated solution to two of the biggest problems in physics: the strong CP problem and dark matter. The Axion Dark Matter eXperiment (ADMX) is a haloscope search aiming to detect axions from the galactic halo. ADMX Run 1c scanned an axion mass range of 3.3 ueV to 4.2 ueV, placing stringent limits on the axion parameter space. In addition to the isothermal halo model, the caustic ring model predicts the existence of narrow substructure within the halo. A follow-up analysis was performed searching for this substructure. An overview of ADMX and the results of the Run 1c analysis will be presented.
