Lawrence's 60-inch (152 cm) cyclotron, c. 1939, showing the beam of accelerated ions (likely protons or deuterons) exiting the machine and ionizing the surrounding air causing a blue glow. A cyclotron is a type of particle accelerator invented by Ernest Lawrence in 1929–1930 at the University of California, Berkeley, [1] [2] and patented in 1932.
Description: 60-inch cyclotron, 1939. This shows the cyclotron at the Lawrence Radiation Laboratory, Berkeley, soon after completion in 1939. The key figures in its development and use are shown, standing, left to right: Dr D Cooksey, Dr D Corson, Dr Ernest Orlando Lawrence (1901-58), the inventor of the cyclotron; Dr R Thornton, Dr J Backus, WS Sainsbury [W. W. Salisbury], Dr LW Alvarez (1911 ...

Lawrence's 60 inch cyclotron, with magnet poles 60 inches (5 feet, 1.5 meters) in diameter, at the University of California Lawrence Radiation Laboratory, Berkeley, in August, 1939, the most powerful accelerator in the world at the time.
Initial Performance of the 60-inch Cyclotron of the Wm. N. Crocker Radiation Laboratory, University of California, Physical Review, Vol. 56, p 124, July to 'December, 1939, New York. (with E. O. Lawrence and others.)
The 60-inch (1.52 m) cyclotron soon after completion in 1939. The key figures in its development and use are shown, standing, left to right: Donald Cooksey, Dale R. Corson, Ernest Lawrence, Robert L. Thornton, John Backus, and Winfield Salisbury. In the background are Luis Alvarez and Edwin McMillan.
Cockcroft supervised the work. The cyclotron was in operation by October 1938, and the new wing was completed in 1940. [30] Oliphant felt that the cyclotron was not big enough, and commenced construction of a larger 60-inch cyclotron at the University of Birmingham.
In their experiments, they used a 60-inch (150 cm) cyclotron. [6] Curium was chemically identified at the Metallurgical Laboratory (now Argonne National Laboratory), University of Chicago. It was the third transuranium element to be discovered even though it is the fourth in the series – the lighter element americium was still unknown. [7] [8]
