Description
The QUAX experiment searches for axion dark matter in the 35–45 μeV mass range using complementary cavity haloscopes at INFN Legnaro and Frascati. This talk will focus on the Padova/Legnaro haloscope, which has reached near-KSVZ sensitivity above 40 μeV. The experiment employs a tunable, dielectrically loaded copper cavity in an 8 T magnetic field and a quantum-limited readout chain based on a traveling-wave parametric amplifier (TWPA). Ongoing R&D on transmon-based single-photon detection will also be presented, together with LC-circuit detection scheme with a high magnetic field and SQUID amplifier for gravitational-wave and their possible application to low-mass axion searches.
