QCD axion is a hypothetical particle proposed to solve the strong CP problem and one well-motivated dark matter candidate for killing two birds with one stone. The Axion Dark Matter eXperiment (ADMX) builds axion haloscopes to search in the golden parameter space for the post-inflation scenario, probing the conversion of axions into photons stimulated by a large magnetic field. We have reached to Dine-Fischler-Srednicki-Zhitnisky (DFSZ) couplings for axions (~1micro eV mass) with near-quantum-limit-noise amplifiers. In this talk, I will present the preliminary result of Run1C-extended for axion masses 3.23-3.337 micro-eV (791.6-807.0 MHz) and the progress of Run1D phase.



Dr. Dan Zhang earned her Ph.D. in 2022 at the University of Maryland, College Park, working on WIMP search and sub-MeV fermionic dark matter absorption search in PandaX collaboration. Now, she is a postdoctoral researcher working on QCD axion dark matter search at the University of Washington.
