The HAYSTAC Collaboration
HAYSTAC (the Haloscope at Yale Sensitive to Axion Cold Dark Matter) is a tunable microwave cavity experiment searching for axion dark matter. HAYSTAC serves both as an innovation test-bed for new technologies and as a pathfinder for axion searches in the mass range 10-100$\mu$eV. Phase 1 of the experiment explored axion models from 23.15\,\textless$\,m_{a}$\,\textless$\,$24.0$\,\mu$eV. In 2019, HAYSTAC is entering its second phase of operation. Upgrades include the further adaptation of quantum measurement techniques to incorporate a new squeezed-state quantum receiver, the installation of a new dilution refrigerator, and an overhaul of the data acquisition software. I will summarize the current status of the experiment and the expected sensitivity for HAYSTAC Phase II.
