124 years ago today, August 8, 1901 (June 24, 1901 in the lunar calendar), American physicist Thomas Lawrence was born. Lawrence and his cyclotron was born on August 8, 1901. American physicist Thomas Lawrence was born on August 8, 1901. American physicist. In 1927, he served as assistant professor in physics at Yale University, and later as associate professor at the University of California. In 1930, he was promoted to professor. The cyclotron was conceived in 1929. His student Livingston designed and built a device that could accelerate hydrogen ions (protons) to an energy of 13,000 electron volts. He later set about building a second cyclotron, which could accelerate protons to 1.2 million electron volts, enough to cause nuclear transformation. To continue the project, he established the Radiation Laboratory in Berkeley and became director of the laboratory in 1936. Technetium, the world's first man-made element, was produced in Lawrence's cyclotron. Lawrence's basic design has also been used in other particle accelerators, and great progress in the field of particle physics has been achieved mainly through these accelerators. Lawrence won the Nobel Prize in Physics in 1939 for inventing the first high-energy particle accelerator, the cyclotron. During World War II, he participated in the Manhattan Project and was in charge of the electromagnetic separation of uranium-235 used to make the atomic bomb. In 1957, the U.S. Atomic Energy Commission awarded him the Fermi Prize. He also invented and patented the color television picture tube. The Lawrence Laboratory in Berkeley and Livermore, California, element No. 103, was named in his honor. He died on August 27, 1958. Comments: The invented cyclotron plays a particularly important role in the study of nuclear fission and nuclear force.
