Music Applause on the campus of Stanford University. - The world's largest linear electron accelerator is taking shape, essentially an electron microscope 2 miles long. - It will permit man's most refined exploration of the atomic nucleus. - This is a project of massive proportions and unprecedented accuracies. - Two and a half million cubic yards of Earth have been moved, 130,000 cubic yards of concrete have been poured, and 10,000 tons of steel bars are reinforcing the two-mile-long structure. - The structure will contain the basic component of the accelerator, a tube of pure copper four inches in diameter, 10,000 feet long, and straight to within the thickness of a dime. - This unique complex accelerator structure is composed of 240 modular units, each 40 feet long. - Their fabrication entails some of the most advanced processes ever developed. - The basic segment or module consists of a 40-foot aluminum pipe or girder. - On the pipe, there are mounted four aluminum support brackets called strong backs. - Each strong back supports a 10-foot section of copper accelerator pipe or discs loaded waveguide, whose function is to guide the microwaves of energy which accelerate the electrons. - Other parts of the module include the copper rectangular waveguides, which carry the energy from its source, the klystron tube, to the disk loaded waveguide, and the small copper pipes of the cooling system. - Literally hundreds of vendors from more than a dozen states supplied the materials and equipment necessary to fabricate the modules at the Stanford Linear Accelerator Center. - The most sophisticated component of the module is the disc loaded waveguide. - It is constructed from 84 cylinders approximately four inches in diameter and one inch long. - There are also 85 discs approximately four inches in diameter with...
