Scientific paper
A Post Mortem System was developed for the Relativistic Heavy Ion Collider at Brookhaven National Laboratory to provide a playback of the collider state at the time of a beam abort, quench, or other failure event. Post Mortem data is used to provide diagnostics about the failure and to improve future stores. This data is read from hardware buffers and is written directly to the main file system by Accelerator Device Objects in the front-end computers. The Post Mortem System has facilitated analysis of loss monitor and power supply data, such as beam loss during magnet quenches, dump kicker misfires and power supply malfunctions. System details and recent operating experience will be discussed.
