Overall smooth running at Pm= 580 MeV. We are getting close to achieve the minimum statistics goal (~2880 mC) for this setting. HMS dipole randomly ramped down to zero once during the swing and again during the owl, but we could restore with no issue.

Mark and Holly took Optics runs for the saturation study around 2 pm yesterday. Based on the study, saturation effects in Q1 and Q3 have been removed and the field program has been updated accordingly (https://logbooks.jlab.org/entry/3555447, https://logbooks.jlab.org/entry/3555436). We took LH2 and lowest Pm (=80MeV) setting data with updated SHMS magnet setting and moved back to Pm=580MeV.

We had cdaql1 hanging while we were replaying data (https://logbooks.jlab.org/entry/3555593). Steve Wood was called and he commented out access to /cache in the replay and reboot cdaql1, and it brought cdaql1 back up. It came back around around 2am, and Steve could resolve it (https://logbooks.jlab.org/entry/3555670).

Today, the plan is to continue taking data for the D2-Electro Disintegration. There will be few hours of downtime expected due to Hall B pass change. It will happen around 10am and will take a few hours. We would like to keep the Hall lock up unless there is any urgent rapid access request. If there is, please let me know as soon as possible.

Reminder: the shift schedule has been extended until May 7th

We will meet in 200C at 1:30 pm (second floor of the counting house).
