Abstract

One reason for the Spallation Neutron Source (SNS) adoption of superconducting cavities, was the possibility of fault tolerance. Namely, the ability to rapidly recover from a cavity failure, retune the downstream cavities with minimal user disruption. While this is straightforward for electron machines, where beta is constant, it is more involved for the case of proton machines, where the beta changes appreciably throughout the Superconducting Linac (SCL). A system for quickly calculating new cavity phase setpoints in the event of the change in one or more cavity amplitude and or phase settings has been developed. Typical phase adjustments are in the 100 - 1000 degree range. This system has been tested on the SNS SCL in both controlled tests and a need based cases. This scheme and results will be discussed.
