About Us

The Center for Experimental Nuclear Physics and Astrophysics (CENPA) is the new name for the organization developed from the Nuclear Physics Laboratory at the University of Washington.

CENPA supports a broad program of experimental physics research in fundamental symmetries, neutrinos, muons, axions, and non-Newtonian gravitation.  A major portion of our effort is involved with experiments done elsewhere using equipment we develop here, supporting a vigorous research program at sites as varied as the Sanford Underground Research Facility in South Dakota, Fermilab in Illinois, the Paul Scherrer Institute in Switzerland, and the Karlsruhe Institute of Technology in Germany.  CENPA is home to the Axion Dark Matter eXperiment (ADMX) and the Eöt-Wash precision gravity group.  A 9-MV Tandem Van de Graaff Accelerator provides intense beams of light ions, and the world's most intense helium-6 source.

Our program in neutrino research includes continuing analysis of data from the Sudbury Neutrino Observatory in Canada, participation in the KATRIN tritium beta decay experiment, and development of the cyclotron radiation spectroscopy method (Project 8) as a technique for neutrino mass measurement and fundamental symmetries studies.  We are major participants in the Majorana Demonstrator (76Ge) experiment to search for neutrinoless double beta decay.

The muon program includes the new experiment at Fermilab to measure the anomalous magnetic moment of the muon, and experiments at PSI to determine the muon lifetime, pseudoscalar coupling constant, and the weak coupling of neutrinos to the deuteron.
