First Results from ADMX G2


The axion is a well-motivated dark matter candidate inspired by
the Peccei-Quinn solution to the Strong-CP problem. After
decades of work, the US DOE flagship axion dark matter search,
ADMX G2, is the first experiment to be sensitive to dark matter
axions from the plausible DFSZ coupling model, and has begun
to search the theoretically-favored axion mass region 2-40
micro-eV. ADMX G2 could now discover dark matter at any
time. I will report the first results from exploring the range
around 2.7 micro-eV last year, discuss this year's operations
and review the ADMX G2 plans to continue the search to cover
the entire mass range.
