Operational status and analysis results of ADMX-G2 Run 1C-extended
ORAL
Abstract
The discovery of axions could resolve two important puzzles at the same time: the strong CP problem and the abundance of dark matter. The Axion Dark Matter eXperiment (ADMX) probes the conversion of axions into photons with a high-Q tunable resonator immersed in a strong magnetic field. Leveraging an ultra-low-noise amplifier chain, ADMX has already achieved Dine-Fischler-Srednicki-Zhitnisky (DFSZ) coupling sensitivities to micro-eV axions. In this talk, I will summarize the status of the experiment and present the latest results of the on-going Run 1C, an extended search for DFSZ axions in the 3.23-3.337 and 3.900-3.924 micro-eV mass range.
