The History of AcceleratorsInside the Nucleus |
||||
 |
John D. Cockcroft and Ernest T. Walton built the first accelerator in the 1930s to explore the nucleus. A high voltage was needed to reach the high acceleration and high energy needed for a charged particle to penetrate into the nucleus. Cockcroft and Walton managed to construct an electric system that could deliver a voltage of 800 kV, which was used in the first proton accelerator. In 1932 they realised the first nuclear transformation initiated by a proton. p + Li -> He + He Cockcroft and Walton received the Nobel Prize in 1951 "for their pioneer work on the transmutation of atomic nuclei by artificially accelerated atomic particles." |
