Ernest Orlando Lawrence (August 8, 1901 – August 27, 1958) was an American nuclear physicist and laureate of the Nobel Prize in Physics in 1939 for his invention of the cyclotron. [1] He is known for his work on uranium-isotope separation for the Manhattan Project , as well as for founding the Lawrence Berkeley National Laboratory and the ...
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.
It is named after Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranium element, the third transfermium, and the last member of the actinide series.
A disappointed Oliphant flew to the United States to speak to the American scientists. These included Ernest Lawrence at the University of California's Radiation Laboratory in Berkeley. [12] The two men had met before the war, and were friends. [13] Lawrence was sufficiently impressed to commence his own research into uranium. [12]
On January 2, Ernest Lawrence and M. Stanley Livingston complete the first cyclotron, a type of circular particle accelerator. This early design is only 4.5 inches in diameter and yields a maximum proton energy of 80 keV. [2] [3] 1932. On January 1, Harold Urey, Ferdinand Brickwedde, and George M Murphy publish the discovery of deuterium.

Ernest Lawrence's first cyclotron was a mere 4 inches (100 mm) in diameter. Later, in 1939, he built a machine with a 60-inch diameter pole face, and planned one with a 184-inch diameter in 1942, which was, however, taken over for World War II -related work connected with uranium isotope separation ; after the war it continued in service for ...
The Ernest Orlando Lawrence Award was established in 1959 in honor of a scientist who helped elevate American physics to the status of world leader in the field.. E. O. Lawrence was the inventor of the cyclotron, an accelerator of subatomic particles, and a 1939 Nobel Laureate in physics for that achievement.
