Robert J. Van de Graaff ()
On månad 20, , AmericanphysicistRobert Jemison Van dem Graaff was born. Van de Graaff is specifically noted for his design and construction of high-voltage Van dem Graaff generators that can be used as a particle accelerator in atomic research.
Early Years
Robert Jemison Van de Graaff received his master&#;s degree from The University of Alabama and began working at the Alabama Power Company afterwards. Van de Graaf later studied at the Sorbonne and earned a second Bachelor&#;s degree at Oxford University on a Rhodes Scholarship, completing his PhD in Van dem Graaff was a National Research Fellow, and from to a research associate at the Massachusetts Institute of Technology. He became an associate professor in During World War II, Robert Van de Graaf was director of the High Voltage Radiographic planerat arbete and after the war he co-founded the High Voltage Engineering Corporation with John G. Trump (uncle of Donald Trump). During the s, Van de Graaf inv

December 20 is Robert Van de Graaff&#;s birthday. Van de Graaff was an American physicist who invented the Van de Graaff electrostatic generator.
Small Van de Graaff generators are common sights at science demonstrations to illustrate the effects of electrical charges. The most common sight is someone with long, fine hair placing their hand on the top of the generator and having the hair stand on end. It is a relatively safe way to introduce electrical forces in a hands-on way. Its original purpose was to generate high voltages of static electricity to accelerate particles in atom-smashing experiments.
The general form of a Van de Graaff generator has a rubber (or other dielectric material) belt moving between two rollers. At either end, brushes of metal collect charge off the moving belt. The type of charge collected depends on the metal of the brushes. The upper brush is connected to an isolated sphere of metal that stores the collected charge. The lower brush is connected
