Abstract:

What is the particle nature of dark matter?  No standard model particle seems to fit, but the axion, a hypothetical particle motivated by the strong CP problem in nuclear physics, is an excellent candidate.  The Axion Dark Matter eXperiment (ADMX) is an axion 'haloscope' that searches for local dark matter axions through their conversion to microwave photons in a strong magnetic field.  ADMX is gradually expanding its reach to cover a wider range of theoretically well-motivated axion masses and couplings.  I will discuss the principle of the axion haloscope as a dark matter search and its sensitivity to local dark matter structure, the current operations of ADMX, the near term search strategy, and potential improvements in future axion searches.

Bio:


Gray Rybka is an Assistant Professor of Physics at the University of Washington. His research focuses on precision measurements to expand our knowledge of the fundamental particle building blocks of the universe. These experiments often involve the use of superconducting quantum electronics in a deep cryogenic environment. He is co-spokesperson of the Axion Dark Matter Experiment (ADMX), which searches for microwave signals produced from dark matter conversion in a superconducting magnetic field. He is also involved in the Project-8 effort to measure the neutrino mass scale using Cyclotron Radiation Emission Spectroscopy.
