Automatic Centering and Matching of Cyclotron Beams

The task of automatic centering and matching comprises the following four steps: It starts with taking a probe trace, followed by its interpretation yielding the turn structure. From this, one can find the error in centering and matching which forms the basis to calculate the parameter changes for its correction. Some problems arising from these steps are discussed and are illustrated with the practical example of the control-computer program that has been developed for the SIN 590 MeV Ringcyclotron.
