Cooksey note: Looking from above at the "east" side, one sees, below the union of the two dee support tanks, the high speed (approximately 5000 L/sec) oil diffusion pump developed in this laboratory.

The four-inch bubble chamber. The first hydrogen chamber to produce results of scientific interest. It was built at Lawrence Radiation Laboratory in 1955 by Doug Parmentier (l.) and Pete Schwemin (r.), technicians in the Alvarez group. The year before, Parmentier and Schwemin, continuing a line of research begun by their coworker John Wood, had demonstrated another important "first." The first workable chamber of combined metal-and-glass, rather than all-glass, construction. That chamber, the 2 1/2-inch, was the first real prototype of a modern, practical, liquid-hydrogen bubble chamber. Photograph taken November 19, 1954. Bubble Chamber-2
