Please find a detailed report for the past 24h data-taking of July 15th: RC summary: https://logbooks.jlab.org/entry/4419181 

  *   MCC took beam-down for the 4th pass RF at around noon 12pm. We requested controlled access. Florian and Sergey went down and replaced BAND TDC inherited from Hall C, work done at 4:30 pm<https://logbooks.jlab.org/entry/4418625 >. MCC took longer than expected<https://logbooks.jlab.org/entry/4418610 > to bring back beam until around 10 pm. After empty the target, we conducted 2H01<https://logbooks.jlab.org/entry/4418720 > , 2C24A harp scan here<https://logbooks.jlab.org/entry/4418733 >, and two additional harp scans by modifying the 2C24 x position (-2.0 -> -1.8mm<https://logbooks.jlab.org/entry/4418754 >) and y position ( 1.3 -> 1.1mm<https://logbooks.jlab.org/entry/4418766 >) by 2mm to study the stability.
  *   After that, we filled target and requested beam back. Resumed physics data taking starting mid-night 23:57pm. RC will be turned over to Florian Hauenstein.


Our plan is to continue the physics run on 4He + 325nA until the MCC maintenance day, Thursday 7 am.

Best,
Zhiwan
