In 1929 Ernest Lawrence – then associate professor of physics at the University of California, Berkeley, in the US – invented the cyclotron, a device for accelerating nuclear particles to high velocities without the use of high voltages. Lawrence was granted US patent 1948384 for the cyclotron on 20 February 1934.

There are over 1500 cyclotron facilities around the world, and the IAEA has recently updated its interactive map and database featuring 1300 of these cyclotron facilities from 95 countries.
