Lawrence Berkeley Laboratory. Physics Division
LBL Physics Division scientific logbooks of Owen Chamberlain, Emilio Segr ̈and Clyde Wiegand, 1946-1954.
These logbooks document the group experiments of Owen Chamberlain, Emilio Segr,̈ and Clyde Wiegand. Segr'̈s group constructed an elaborate detecting system, including advanced circuitry designed by Wiegand and a Cerenkov counter designed by Wiegand and Chamberlain. The experiments involved polarized high-energy protons and lead to the discovery of the antiproton, including n-p, d-p, p-d scattering experiments, using the Bevatron accelerator at the Lawrence Berkeley Laboratory (LBL). In 1959, Owen Chamberlain and Emilio Segr ̈won the Nobel Prize for the discovery of the antiproton.
The laboratory was founded as the University of California Radiation Laboratory in 1931 by Ernest Orlando Lawrence, a University of California Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It is a United States Department of Energy National Laboratory, operated by the University of California. The name of the laboratory has evolved since its founding: Lawrence Radiation Laboratory (1931-1958), the Lawrence Berkeley Laboratory (1959-1995), and currently the Lawrence Berkeley National Laboratory (1995-present).
