Ernest Orlando Lawrence was an 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 a Ph.D. at Yale University in 1925. An assistant professor of physics at Yale (1927–28), he went.

A cyclotron is a type of particle accelerator invented by Ernest Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path.
A device about 4.5 inches in diameter used a potential of 1,800 volts to accelerate hydrogen ions up to energies of 80,000 electron volts. Lawrence immediately started planning for a bigger machine. In summer 1931 an eleven-inch cyclotron achieved a million volts.
Ernest Lawrence (August 8, 1901–August 27, 1958) was an American physicist who invented the cyclotron, a device used to accelerate charged particles in a spiral pattern with the help of a magnetic field. The cyclotron and its successors have been integral to the field of high-energy physics.
