Westinghouse Atom Smasher

The Westinghouse Atom Smasher was a 5 million volt Van de Graaff electrostatic nuclear accelerator operated by the Westinghouse Electric Corporation at their Research Laboratories in Forest Hills, Pennsylvania. It was instrumental in the development in practical applications of nuclear science for energy production. In particular, it was used in 1940 to discover the photofission of uranium and thorium, and was most cited for certain nuclear physics measurements. The Westinghouse Atom Smasher was intended to make measurements of nuclear reactions for research in nuclear power. It was the first industrial Van de Graaff generator in the world, and marked the beginning of nuclear research for civilian applications. Built in 1937, it was a 65-foot-tall (20 m) pear-shaped tower. It was essentially unused after World War II, and the main structure was laid on its side in 2015. In 1985, it was named an Electrical Engineering Milestone by the Institute of Electrical and Electronics Engineers.
