Backbone of Stanford's linear accelerator (called SLAC) is a 10,000-ft.-long, 4-in.-diameter copper tube housed in a concrete tunnel and buried 25 ft. underground to protect scientists and any bystanders from its fierce radiation. At one end, an electron beam is generated in much the same manner as the beam inside a home TV picture tube. Injected into a nickel-size hole that runs the length of the copper tube, the beam's electrons are immediately accelerated by 6,000,000-watt microwave pulses generated by 245 klystrons-giant, ultrahigh-frequency radio tubes...
...energy imparted to the electrons by the radio wave is in the form of mass. As a result, each electron increases its mass 40,000 times, and has acquired about 20 billion electron volts (BEV) of energy by the time it reaches the far end of the copper tube. There, the extremely powerful stream of charged particles passes through a beam "switchyard," where giant electromagnets direct it into one or another of two target buildings, or split it between both...
...gobbles copper, and so does prosperity. In the U.S., 13% of copper production is now reserved for Viet Nam military needs. At the same time, demand for color TV sets, appliances and cars has helped boost consumption 17% this year to a rate of 2,344,000 tons, nearly half of the metal's world output. With Europe and Japan also using more copper, the extra demand has come too fast to be met by producers plagued by strikes in Chile and by tensions between white Rhodesia and black Zambia...
...Other steel consumers have moved in where autos used to reign. Example: Railroads plan to build 90,-000 new freight cars this year, against about 65,000 in 1965. In smaller measure, the steel industry is benefiting from an all-out drive to use its products as substitutes for copper, in everything from plumbing to refrigerator tubing. Reason: copper prices have been driven sky-high by copper-rich countries, such as Chile and Zambia, cashing in on a world shortage...
...vitamins are A, D, E, C (ascorbic acid), B1 (thiamine), B2 (riboflavin), Niacin, B6, folic acid, pantothenic acid, and B12. The minerals are calcium, phosphorus, magnesium, iron, iodine and copper...
