Abstract
The axion is a hypothetical particle arising from the Pecce-Quinn solution to the Strong CP problem, and an excellent candidate for dark matter. The Axion Dark Matter Experiment (ADMX) is an experiment that searches for axions as a dark matter with a resonant cavity under a strong superconducting magnetic field. In previous operations, ADMX achieved sensitivity to the GUT-inspired DFSZ axion model between 2.7-3.3 micro eV with yocto Watt level background using a quantum amplifier and dilution refrigerator. The latest run has been in data-taking since 2020. In this run, we have improved our blind axion signal injection, improved our operating efficiency, and have new methods to distinguish true axion signals from the background. I will discuss these advances as well as the current data-taking status.
