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 outwar

…Kossel; he submitted the thesis in 1927/1928 and his doctorate was awarded in January 1929. While a student at Kiel, he formulated the concept of the cyclotron. From 1927 to 1945, Steenbeck was a senior staff scientist at the Siemens AG in Berlin. From 1934, he was a laboratory director, and it was in that…
