Well, it is always interesting to peruse the EPICS Archiver. Both the Left VDC trip and the Left Septum power supply trip occured when beam current was increased. That they are both named "Left"-something is really just a coincidence, the power supply is to the right and upstream of the target. Most likely we had a small beem steering problem and some bad luck. The problematic Right Septum seems to be performing normally(No, not sparking at every opportunity. No!). The trip of the Left Septum supply is presumed to be due to a corruption of the micro-controller from background radiation.
