The cyclotron and the war: Construction of the 60-inch cyclotron in Japan


Experimental nuclear research started at the end of 1920s. In 1932, in Berkeley, Ernest O. Lawrence invented a useful experimental instrument for this purpose, the cyclotron. A cyclotron is a particle accelerator that gives charged particles high energy. With these particles, physicists could observe various nuclear phenomena in the laboratory.
