Mitigating Cathode Overcurrent Faults at the Spallation Neutron Source

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

The high-power klystron amplifiers at the Spallation Neutron Source (SNS) have been in operation for over 100,000 hours. Overcurrent faults from the klystron cathodes comprise the bulk of RF System downtime. Reliable operation is of particular interest to the SNS, and data from over a decade of operation is used to help mitigate repetitive overcurrent conditions.
