The accelerator took the time yesterday to do some RF recovery and managed to reduce the Hall C beam waist by 25% which eventually allowed them to send beam to everyone without significant BLM trips. This was time well invested as mid swing we were in a good steady running state. This continued all through the OWL. We have completed 2 whole slugs and we are 0.65C into slug 112. The regular and analysis shifters paid close attention to the data and so far so good. We plan to keep this high efficiency all the way through Monday. 

The only issue of note was the vacuum excursion that is detailed in: https://logbooks.jlab.org/entry/3766080 https://logbooks.jlab.org/entry/3766337 It seems that it was most likely due to a orbit excursion all the way into our arc. It was fixed in relatively short order and we have not had any similar issues since.

We will not have regular RC meetings until Tue. However if the situation requires I will call a meeting on the day. If you are interested in the quality of the data please join the 11AM W(eekly) A(analysis) C(oordinator) meeting: https://www.bluejeans.com/454783784
