Abstract

I discuss the latest developments on the Princeton Axion Search (PXS), a search for QCD axion dark matter in the 0.8-2.1 ueV mass range (200-500 MHz frequencies). PXS addresses the transitional range between cavity haloscopes and the DMRadio program, which operates below any cavity modes and utilizes lumped-element techniques. I describe development efforts on all aspects of the experimental apparatus, including the cryogenics, solenoidal magnet, near-quantum-limited readout amplifiers, and resonator. PXS leverages a partnership with the DOE Princeton Plasma Physics Laboratory to design and construct a large-bore, conduction-cooled solenoid. It also benefits from a partnership with Caltech/NASA JPL to implement parametric amplifiers in this frequency range. PXS is developing superconducting resonators and readouts beyond the Standard Quantum Limit of amplification in collaboration with the DMRadio program, which aims to probe the lower sub-ueV mass range. I discuss some of these collaborative efforts.
