Future high-power Superconducting Radio Frequency (SRF) Linacs may need to operate with strict limits on beam trip durations on the order of a few seconds. In order to provide the desired beam powers, these linacs will require significant numbers of SRF cavities which increases the probability of beam trips. The SRF linac at the Spallation Neutron Source (SNS) is currently operating with 81 SRF cavities to provide 1 GeV protons for neutron production. The typical SRF cavity trip rate is approximately 2-3 trips per week each with a recovery time on the order of a few minutes. Occasionally an SRF cavity cannot be recovered and downstream cavities must be re-phased in order to recover the beam energy. Downtime for this type of event is on the order of 30 minutes. As part of a controlled test, it has been demonstrated that after an SRF cavity trip high-power production-quality beam can be recovered automatically without operator intervention in only a few seconds.
