Description
The Haloscope At Yale Sensitive To Axion CDM (HAYSTAC) Experiment is actively searching for QCD axions using a resonant microwave cavity enhanced by a quantum squeezed state receiver (SSR). Because the axion’s mass and coupling strength are unknown, a crucial metric is the scanning rate across the parameter space. Integration of the SSR into the HAYSTAC experiment has allowed for a scan rate enhancement of up to 2x. More recently, HAYSTAC has improved its system stability, enabling the SSR to operate reliably across a wide range of axion masses. I will discuss HAYSTAC's latest results in the mass range between 17-20 μev, current status, and future plans.
