A Fast DSP-Based Phase-Detector for Closed-Loop RF Control in Synchrotrons

摘要

A digital signal processor-based phase detector system is described whose performance is sufficient to implementa beam-phase control or other radio frequency closed-loop control systems which are typical for heavy ion synchrotrons. The delay caused by the system is less than 10 mus, and the accuracy of the detected phase is better than +-1deg for unmodulated signals. Although beam-phase control is the target application, the system may also be used in totally different fields of application. A number of measurement results show the high potential of this solution.
