[Prex] [New Logentry] RC status summary 09/02

We stayed in production yesterday and throughout the night with the exception of a two hour interruption during swing for issues with the RF separator.  Hall B's large backgrounds returned and as a result we had a lot of beam trips from Hall B. Overnight, efficiency was rather low. From 8AM yesterday to 10AM today, we collected 7.22 good Coulombs representing slightly over 50% efficiency.

At 10AM beam was taken away for RF recovery. This will take all of Day shift and likely into swing at which point recovery of Hall C 5-pass is expected to start. This recovery is invasive to other halls so we likely will not see much of anything until late swing.

I released the SL for Day shift after beam was taken away. This will reduce the counting house personnel and allow two techs to install shelving in the center DAQ room to allow new equipment to be installed for BCM studies related to MOLLER. We have left the Hall in beam permit with the magnets up, so the TO will remain on shift. Swing shifters should report as usual.

We have scheduled a Moller polarimetry measurement to begin Friday morning at 8:30AM. Eric King will be taking the day shift to help with this measurement.

Counting house shifts are filled through this weekend, but starting Monday Owl there are two Owl shifts open. Please sign up if you can.
Analysis shifts are wide open starting Saturday. Offsite folks, please sign up.

We will have our usual RC meeting today at 3:30PM
