In 1934 Alikhanov and Igor Kurchatov built a "baby cyclotron", which became the first "cyclotron" operating outside of Berkeley, California where Ernest Lawrence had invented it years earlier. It did not operate for long, though some experiments were conducted. The first proper cyclotron in the Soviet Union was built at the Radium Institute in Leningrad by 1936.
