Description

The Spallation Neutron Source (SNS) is the highest power pulsed proton linac in the world routinely delivering 1.44 MW of beam power. For high-power accelerators, like the SNS, the main operational areas of focus are minimizing beam losses and reducing trip frequency. Since beginning high-power operation SNS has been optimizing beam losses and recording beam trip statistics of varied lengths. The operational focus on beam trips and the forethought to install an abundance of diagnostics has allowed for a steady decrease in trip rates year over year. The decrease can be attributed to utilizing alarms and interlocks, downtime trending, equipment diagnostics, and the ability of operations resources to provide system engineers with narrow areas for focused troubleshooting. The focus here will be on the specifics for how SNS has continued to systematically reduce beam trip frequencies across a range of time durations.
