Historical NoteReturn to Top

Shortly after the end of World War II, Prof. Joseph E. Henderson proposed a 60-inch cyclotron for nuclear physics research at the University of Washington. Construction began in April, 1948, and full external beam was achieved in 1952 under the leadership of Prof. Fred Schmidt.

In 1962-63 a National Science Foundation grant supported the purchase of a tandem van de Graaf accelerator. A building addition to the cyclotron building was completed in 1964, and the accelerator became operational in 1965. The new facility was called the Nuclear Physics Laboratory (NPL).

In 1994 a shift away from accelerator-based research began with the Sudbury Neutrino Observatory project, and in 1998 the Nuclear Physics Laboratory formally became the Center for Experimental Nuclear Physics and Astrophysics (CENPA). CENPA was established in 1998 at the University of Washington as the institutional home for a broad program of research in nuclear physics and related fields. CENPA supports a broad program of experimental physics research in fundamental symmetries, neutrinos, muons, axions, and non-Newtonian gravitation.

9.33 cubic feet (8 boxes)

Scope and Content: Laboratory notebooks and data of the Eöt-Wash Experimental Gravity Group. Includes the hand-written notebooks, and 5.25 in floppy disks, CDs, and a 3.5 in floppy disk with computer data.

Biographical/Historical Note: The Eöt-Wash Group in the University of Washington Center for Experimental Nuclear Physics and Astrophysics works to pioneer new techniques to test and measure weak-field gravity, search for possible new interactions weaker than gravity and is involved in technology for the Laser Interferometer Gravitational Wave Observatory (LIGO). It's research goals are to

1) Search for experimental signs of quantum gravity that violate Einstein's Equivalence Principle and/or the Newtonian inverse-square law.

2) Probe the largely unexplored region of possible interactions weaker than gravity.

3) Make sensitive tests for new interactions that couple to electron spin.

4) Develop sensitive low-noise instrumentation for the Laser Interferometer Gravitational Wave Observatory (LIGO)
