One evening,a husband and wife are working in their garden. While watering the grass, the wife holds the hose horizontally and the water flows from the end of the hose. She twists the nozzle of the hose to partially close it and suddenly the water shoots farther from the end of the hose. This seems odd to her husband, who wonders, "Why does the stream of water travel farther, since it appears that less water is flowing from the end of the hose?" My challenge is to give a scientific explanation for this unnatural phenomenom.
Professor Donald Kerst built the world's first magnetic induction accelerator at the University of Illinois in 1940. After the new machine was referred to variously as a "rheotron," an "inductron," a "Super-X-Ray Machine," and a "cosmic ray machine" in early press releases, a departmental contest was held to name it.
"Ausserordentlichhochgeschwindigkeitelektronenentwickelndenschwerarbeitsbeigollitron" was one of the more original entries. Kerst settled on "betatron." The original betatron is now on display at the Smithsonian Institution.
In 1950, a 300-MeV betatron, more powerful than that called for in the original design, goes online in its own new building on the corner of Stadium Drive and Oak Street. New staff members are recruited to exploit this major new facility, including Giulio Ascoli, Gilberto Bernardini, and Edwin Goldwasser.
