This was one of the primitive cyclotrons developed by the late Ernest O. Lawrence at the University of California, Berkeley, and used during the period 1931-1935.  With this 11-inch cyclotron the 1 million electron volt energy range was surpassed for the first time in the artificial acceleration of particles.  It yielded 1.2 MeV protons in 1932. The instrument cost about $800.  The earliest cyclotron accelerating chambers were about 4 inches in diameter and were built in 1930., Credit Line: Lawrence Berkeley National Laboratory, courtesy of AIP Emilio Segrè Visual Archives, Fermi Film Collection
