HAYSTAC (Haloscope At Yale Sensitive To Axion Cold dark matter) incorporates a dilution refrigerator and Josephson parametric amplifier and has thus achieved a system equivalent noise temperature of twice the Standard Quantum Limit. First data run results exclude axion models a factor of ∼ 2.3 above the benchmark KSVZ model over the mass range 23.55 − 24.0 μeV. These are the first limits within the axion model band in the 10 − 100 μeV mass decade. Ongoing R</td><td width="150"> AB - D is oriented to significantly increase the detector sensitivity through application of a squeezed vacuum state receiver, distributed Bragg reflectors, and photonic band-gap resonators.
