Description
The Axion Dark Matter eXperiment (ADMX) is an axion haloscope detector capable of probing the galactic dark matter halo for axions. ADMX relies on superconducting amplifiers to reach the sensitivity needed to detect QCD axions. The current ADMX and ADMX-Sidecar data taking runs use a flux pumped Josephson parametric amplifier (JPA) and a kinetic inductance traveling wave parametric amplifier (KI-TWPA) to achieve near quantum limited noise performance. I will discuss the deployment, operation, and characterization of these amplifiers in the ADMX detector.
