LBL Physics Division hydrogen bubble chamber logbooks, 1953-1957.
These logs document the development of the hydrogen bubble chamber at the Lawrence Berkeley Laboratory (LBL), beginning with the first experiments by Donald Glaser. Glaser first experimented with superheated liquid in a glass chamber. The particles would leave a track of bubbles as they passed through the liquid, and their tracks could be photographed. He created the first bubble chamber with ether, then experimented with hydrogen after visiting the University of Chicago. Glaser later joined Luis Alvarez's group working on a hydrogen bubble chamber at LBL, where he sought a process in a liquid that could register the path of a charged particle. Glaser thought that bubbles might be formed in a superheated liquid, and in April 1953 Glaser revealed pictures of tracks made by the cosmic-ray muons crossing a small vessel filled with hot ether. By the end of 1953, John Wood of Alvarez's group had made a chamber an inch and a half in diameter and found tracks in liquid hydrogen. The collection includes photographs, as well as a sketch of the first liquid hydrogen bubble chamber (1.5-inch diameter), built by Wood and A. J. Schwemin in 1954.
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).
