Axion Dark Matter eXperiment’s (ADMX) ultra low noise haloscope technology has enabled the40successful completion of two science runs (1A and 1B) that looked for dark matter axions in the2.6641to3.1µeVmass range with Dine-Fischler-Srednicki-Zhitnisky (DFSZ) sensitivity [1, 2]. Therefore, it42is the most sensitive axion search experiment to date in this mass range. We discuss the technological43advances made in the last several years to achieve this sensitivity, which include the implementa-44tion of components, such as state-of-the-art quantum limited amplifiers and a dilution refrigerator.45Furthermore, we demonstrate the use of a frequency tunable Microstrip Superconducting Quantum46Interference Device (SQUID) Amplifier (MSA), in Run 1A, and a Josephson Parametric Amplifier47(JPA), in Run 1B, along with novel analysis tools that characterize the system noise temperature.
