Lawrence, Ernest Orlando Ernest Lawrence with his cyclotron, c. The Granger Collection, New York City (b. Aug. 8, 1901, Canton, S.D., U.S.d. Aug. 27, 1958, Palo Alto, Calif.), American physicist, winner of the 1939 Nobel Prize for Physics for his invention of the cyclotron , the first particle accelerator to achieve high energies. Lawrence earned his Ph.D. at Yale University in 1925. An assistant professor of physics at Yale (1927-28), he went to the University of California, Berkeley, as an associate professor and became full professor there in 1930. Lawrence first conceived the idea for the cyclotron in 1929. One of his students, M. Stanley Livingston, undertook the project and succeeded in building a device that accelerated hydrogen ions (protons) to an energy of 13,000 electron volts (eV). Lawrence then set out to build a second cyclotron; when completed, it accelerated protons to 1,200,000 eV, enough energy to cause nuclear disintegration. To continue the program, Lawrence built the Radiation Laboratory at Berkeley in 1936 and was made its director. One of Lawrence's cyclotrons produced technetium, the first element that does not occur in nature to be made artificially. His basic design was utilized in developing other particle accelerators, which have been largely responsible for the great advances made in the field of particle physics. With the cyclotron, he produced radioactive phosphorus and other isotopes for medical use, including radioactive iodine for the first therapeutic treatment of hyperthyroidism. In addition, he instituted the use of neutron beams in treating cancer.

Lawrence, Ernest Orlando US physicist. His invention of the cyclotron particle accelerator pioneered the production of artificial radioisotopes and the synthesis of new transuranic elements. Nobel prize 1939. During World War II, Lawrence was involved with the separation of uranium-235 and plutonium for the development of the atomic bomb, and he organized the Los Alamos Scientific Laboratories at which much of the work on this project was carried out. After the war, he continued as a believer in nuclear weapons and advocated the acceleration of their development. Lawrence was born in South Dakota and studied there and at Minnesota, Chicago, and Yale universities. He was professor of physics at the University of California, Berkeley, from 1930 and director from 1936 of the Radiation Laboratory, which he built into a major research centre for nuclear physics. The first cyclotrons were made in 1930 and were only a few centimetres in diameter. Each larger and improved design produced particles of higher energy than its predecessor, and a 68-cm/27-in model was used to produce artificial radioactivity. Among the results obtained from the use of the accelerated particles in nuclear transformations was the disintegration of the lithium nucleus to produce helium nuclei.

Legal Notice Creating Laboratory's Future ... Reach Us The E. O. Lawrence Tradition of Excellence That day, though, the new residents had more pressing problems on their minds, as reflected in the minutes of a Project Whitney administrative meeting: "There will be fewer telephones than promised; only the following people will have a one-line system: Teller/Goranson;York/Sewell; Bell/Twitchell; Ransome; Business/Personnel; Theoretical; Storeroom; guard at Post A. It was agreed that we should move to Livermore regardless of the phone situation." "The desk lamp situation is very bad. Every man needs a desk lamp." "No post office box is available at this time. We are on the Postmaster's waiting list." Such were the modest beginnings of an institution that would grow to play a major role in the decades to follow. The founding of the Lab is a story that intermingles conflict, ambition, persistence, and vision. Early Negotiations Approval of Project Whitney, the early designation of the Livermore Lab, was the outcome of several years of debate within government, military, and scientific circles over the need for a second weapons laboratory. Edward Teller, who had made key contributions to the development of thermonuclear weapons while on the scientific staff at Los Alamos, was foremost among those pressing for such a facility. In April of 1950, Teller presented his case for a second laboratory to a joint session of the Atomic Energy Commission (AEC) and its General Advisory Committee (GAC), headed at that time by J. Robert Oppenheimer. (Oppenheimer had served as the first Director of the Los Alamos laboratory and was to become head of the Institute for Advanced Study in Princeton.) Teller's arguments were twofold: the Los Alamos thermonuclear program was not proceeding at a fast enough pace, and a second laboratory would provide a source of mutual competition. At the outset, both the AEC and the GAC were opposed to the idea, and nothing came of Teller's initial effort.

Legal Notice Creating Laboratory's Future ... Reach Us Who Was Ernest O. Lawrence? He was called the "Atom Smasher." The man who "held the key" to atomic energy. This "giant" of physics is Ernest Orlando Lawrence, known to the world as E. O. and inventor of the cyclotron, Nobel Prize winner, and namesake of Lawrence Livermore and Lawrence Berkeley national laboratories. "He saw physics as a kind of adventure," said Herb York, the first Lawrence Livermore National Lab director. "He wanted to do 'big physics,' the kind of work that could only be done on a large scale with a lot of people involved." The invention that would rocket E. O. Lawrence to international fame started out modestly as a sketch on a scrap of paper. While sitting in the library one evening, Lawrence happened to glance over a journal article and was intrigued by one of the diagrams. The idea was to produce very high energy particles required for atomic disintegration by means of a succession of very small "pushes." Lawrence told his colleagues that he had found a method for obtaining particles of very high energy, without the use of any high voltage. The idea was surprisingly simple, but Lawrence double-checked his theory with physicists from Yale to make sure he had not overlooked a critical detail. "Without a doubt, Lawrence's finest achievement was inventing the cyclotron," said York. "The cyclotron impacted future scientific advances." In November 1939, Lawrence won the Nobel Prize in Physics for his work on the cyclotron and its various applications.
