Tuning into Dark Matter with the ADMX Experiment - Livestream

The nature of dark matter is one of the great mysteries of modern physics and could be sourced from new particles beyond the standard model. The Axion, a particle postulated to solve other mysteries in nuclear physics, is one especially well-motivated candidate. These particles, which act more like radio waves, are extraordinarily challenging to detect. The Axion Dark Matter Experiment (ADMX), based at the University of Washington in Seattle, is the flagship search for axion dark matter in the US. ADMX uses a large microwave cavity immersed in a strong static magnetic field to resonantly convert dark matter axions to detectable photons. Recently ADMX has completed several world leading searches with unprecedented sensitivity using superconducting quantum amplifiers. In this talk I will describe the history of axion dark matter searches, describe the recent ADMX results and near-term search prospects and give a survey of the R&D efforts currently underway to explore the entire axion dark matter mass window.
