Characteristics of the UCLA cyclotron radiofrequency system

Journal Article · · Nucl. Instr. Methods
An account is given of the various interdependent factors that must be considered when dees are placed in the valleys of a sector focused cyclotron. The spiral shaped dees and r.f. resonator comprise a half wave structure in which an 11% frequency range is achieved by varying the cross-section of the inner conductor near the node. A grounded grid oscillator is coupled to the resonator by loops and transmission lines. The shape and weight distribution of the dees is such that they can be open on both sides, and yet can be easily supported at the outer radius. The distribution of heat allows the dees to be sawed from 1/4 inch Cu plate with cooling supplied by conduction at the outer radius. They are installed by stretching the vacuum tank.
