FTP, identify this device developed in the early 1930s by E.O. Lawrence.
The azimuthal-varying-field variety of this apparatus increases the average magnetic field near its periphery by achieving focusing via spiral ridge variation of the magnetic field. The synchro- variety is utilized to vary the frequency of the alternating voltage impressed on part of device and can achieve up to one billion electron volts of energy. It consists of one or two hollow D-shaped sections, or dees, assembled with a space between. A magnetic field then deflects particles into a circular path in which acceleration is produced.
