Logentry Text:
Yesterday we did production running up until 2:40 pm (with a brief interruption for BLA calibrations at ~10:15 am). Then we took an opportunistic controlled access (during MCC scheduled down) for about one hour to replace/plug in SHMS Q3 heaters (https://logbooks.jlab.org/entry/3774915). 

We were brought back to beam permit but beam was sent into the Hall C line before the Hall C line dipole string was ready: https://logbooks.jlab.org/entry/3774951 , https://logbooks.jlab.org/entry/3774976. The beam strike interrupted beam to the hall up until 10 pm. Once we got beam back we did harp scans to check the beam profile and after some tweaking we got to an acceptable beam size at the target: https://logbooks.jlab.org/entry/3775032

Production running was resumed close to midnight: https://logbooks.jlab.org/entry/3775066. You can follow the progress of the production running here: https://logbooks.jlab.org/entry/3775373.

There will be no RC meeting today.
