ADMX-Sidecar Status

T he Axion Dark Matter eXperiment (ADMX) is an axion haloscope capable of probing QCD axion dark matter. The QCD axion is a well-motivated particle that solves the strong CP problem in nuclear physics and may constitute a large fraction of dark matter. ADMX Sidecar is a high-frequency axion haloscope sharing the same cryostat as the main ADMX. Sidecar is not sensitive to QCD axions, but it has set new limits on the coupling of axion-like particles to photons. Additionally, Sidecar has been used to test new technologies before they are deployed on the main channel. This presentation will discuss the status of ADMX Sidecar's current data taking run, including work on the piezoelectric motion system, a new kinetic inductance traveling wave parametric amplifier, and upgrades to the synthetic axion generator.
