Lawrence began converting his old 37-inch cyclotron into a giant mass spectrometer. On his recommendation, the director of the Manhattan Project, Brigadier General Leslie R. Groves Jr., appointed Oppenheimer as head of its Los Alamos Laboratory in New Mexico. While the Radiation laboratory developed the electromagnetic uranium enrichment process, the Los Alamos Laboratory designed and constructed the atomic bombs. Like the Radiation Laboratory, it was run by the University of California.
