  The Axion Dark Matter eXperiment (ADMX) is in the midst of an upgrade to
reduce its system noise temperature. ADMX-HF (High Frequency) is a second
platform specifically designed for higher mass axions and will serve as an
innovation test-bed. Both will be commissioning in 2013 and taking data shortly
thereafter. The principle of the experiment, current experimental limits and
the status of the ADMX/ADMX-HF program will be described. R&D on hybrid
superconducting cavities will be discussed as one example of an innovation to
greatly enhance sensitivity.
