Title: Dark Matter Searches with the Axion Dark Matter eXperiment (ADMX)
Abstract: For decades, we have been collecting indirect astrophysical evidence that ordinary matter only
comprises about 5% of the mass-energy content in the universe with the remaining split between dark
matter and dark energy. Potential dark matter candidates span a wide parameter space, and many
parallel efforts are in progress to detect and identify the nature of dark matter. The Axion Dark Matter
eXperiment (ADMX) searches for the axion, a leading low-mass dark matter candidate and a potential
solution to the strong CP problem, by searching for an axion’s conversion to two microwave photons in a
strong magnetic field. I will present an overview of ADMX’s past and present axion searches using a
single microwave cavity and the planned next generation ADMX-2A and ADMX-EFR (Extended
Frequency Range) detectors.
This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore
National Laboratory under Contract DE-AC52-07NA27344.
