| + | (Chris) ~9/3/12 Observations during e11017 indicate that Gretina is failing to validate due to a timestamp syncing issue. Briefly, the timestamps of the digitizers are not reset during run start-up, but S800 receives an "IMP Sync" associated pulse, and the Gretina Trigger system timestamp was reset. This problem may be observed offline by sending a Single IMP Sync; roughly 1 in 30 tries lead to this failure mode. John Anderson at ANL has been informed and debugging will be attempted during the upcoming software working group meeting on 9/21-22. | ||
