Historical Note
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).
The chamber was designed by the Lawrence Berkeley Laboratory Mechanical Engineering Department, under supervision of Paul Hernandez. Design studies for the 72-inch chamber had started early in 1955, and the instrument was completed 65 man-years later, at a cost of $2 million. In a bubble chamber, particles blasted out of a nucleus cleave through this superheated sea like tiny torpedoes, leaving in their wake tiny trails of bubbles that can be photographed. Analysis of a particle's bubble chamber tracks can tell physicists much about the particle's physical properties and history.
Scope and Contents of Collection
These records document the work of the Mechanical Engineering Department at Lawrence Berkeley Laboratory (LBL), the 15-foot Bubble Chamber, the 72-inch Bubble Chamber, cryogenics, and aspects of particle accelerator design. The logbooks (maintained by Paul Hernandez) contain engineering notes, project notes and data, research results and development.
