Postdoctoral Scholar - Axion Dark-Matter eXperiment (ADMX)

Job Description: 

Postdoctoral Scholar - Axion Dark-Matter eXperiment (ADMX)

Applications are invited for a postdoctoral scholar appointment with the Axion Dark-Matter
eXperiment (ADMX). The position is full-time, 12-month (one-year) appointment, which may
be extended, subject to funding and mutual agreement. The Postdoctoral Scholar title is limited
to five years, including postdoctoral experience(s) at UW and other institutions. Funding for this
position is expected to continue through the duration of the current phase of ADMX, 3 or more
years, or until the 5 year limit on postdoctoral scholar positions is reached.
ADMX, a RF-cavity search for axion dark matter in our galactic halo sited at the University of
Washington, is a flagship DOE “Generation 2” dark-matter search. It is in operation after an
extensive upgrade to ultra-low noise JPA microwave amplification and 3-He cooling.
Our group’s technical interests include spectral signal estimation, development of cryogenic and
vacuum instrumentation, and research on microwave resonators and quantum-limited low-noise
microwave electronics. The successful applicant will share our group’s interest in experimental
cosmology, broadly considered, and our interest in challenging measurements. In collaboration
with other ADMX institutions, tasks include operation of the detector, upgrades to the cryogenic
and vacuum systems, data analysis and development of detector technology for next-generation axion searches.
Postdoctoral scholars are represented by UAW 4121 and are subject to the collective bargaining
agreement, unless agreed exclusion criteria apply. For more information, please visit the
University of Washington Labor Relations website.

Applicants must have a Ph.D. (or foreign equivalent) in Physics, Astronomy, or a closely related
field at the time of hire.
