Improvements in the Oric RF System

The Oak Ridge Isochronous Cyclotron has been operating since January 1963. Initial experience with the rf system was enlivened by destructive sparking and general instability at the upper end of the rf tuning range. A network of protective devices developed during the past two years almost eliminates spark damage and improves the stability of the system. A multistage rf voltage regulator was also developed and installed.
