Physics 111: Bubble Chamber (BBC) Physics 111 Advanced Laboratory. Professor Sumner Davis This video used to accompany the Bubble Chamber Experiment, providing students with an introduction to the theory, apparatus, and procedures. This experiment is no longer used in the course. This experiment provides an introduction to elementary particle physics. Interactions and decays of a beam of K- mesons are studied in photographs taken in three stereoscopic views of the Alvarez 72-inch bubble chamber at the old Berkeley Bevatron. The total interaction cross-section, mean lifetime, and a branching ratio are measured. Interactions observed are inelastic charge exchange, hyperon production, 4-prong interactions, and several decay processes. A second set of photographs portrays the interaction of high energy photons with protons in the bubble chamber. This is an exploratory and qualitative experiment in which you observe many particle tracks and learn to identify and classify various interactions and decays, and determine their relative frequencies of occurrence. It's like a treasure hunt with all the excitement of finding something new and very different from ordinary experiments. It is an "observe and tell" experiment. There are no charts or plots or extended mathematical computations required. http://advancedlab.org
