Moving bubble chamber. 72-inch bubble chamber's "walk" from Building 59 to its new temporary site against the Bevatron's west wall. Paul Hernandez of mechanical engineering conceived the ingenious idea of devising a hydraulic walking method. With this system the bubble-chamber magnet could make right angle turns and maneuver into very tight spaces, thus eliminating the need for an outside rigging contractor.

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

Walking the 72-inch bubble chamber. Engineers: Jack Hart, Matt Renkas, Jim Shand, Paul Hernandez, and Bill Eason. Paul Hernandez of mechanical engineering conceived the ingenious idea of devising a hydraulic walking method. With this system the bubble-chamber magnet could make right angle turns and maneuver into very tight spaces, thus eliminating the need for an outside rigging contractor. Patent release 1/5/1959.

The objects in this collection are from The U.S. National Archives and Defense Visual Information Distribution Service. The U.S. National Archives and Records Administration (NARA) was established in 1934 by President Franklin Roosevelt. NARA keeps those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. The Defense Visual Information Distribution Service provides a connection between world media and the American military personnel serving at home and abroad. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.
