The Generation-2 ADMX project is an upgrade of the existing Axion Dark Matter eXperiment to add a high-performance dilution refrigerator to the cavity axion detector. The refrigerator reduces the operating temperature of the experiment from 3–4 K to of order 0.12 K (120 mK). There is a corresponding 20-fold reduction in the background noise of the experiment. The refrigerator has been installed and commissioned. The reduced background has allowed a search for the very weakly-coupled but highly compelling DFSZ-model axions. This search, at this sensitivity, is a definitive experiment, able to detect axions or to reject the axion dark matter hypothesis with high confidence.
