    keyword=Right Q1

    Came in and found the Right Q1 supply unresponsive. It was showing 0A, but at such a point the readback is not to be trusted. The field readback was 0, so no current in the magnet. We made an access and cycled power on the supply. It came back up ok. Also, four of the VESDAs were in alarm. I note that the beam current is down slightly and seems to have been a bit erratic (on the BCM display). We are probably spraying crap (background radiation) all over the hall. Again, having a jazzed-up Q1 control is an anticipated issue given the high background we are running with.
