The beam quality was not great since the restoration after RF recovery yesterday https://logbooks.jlab.org/entry/3607149

Due to beam issues we did not really start production until 21:40 though there was talk of restoring beam to Hall C starting with 2 pm. There were few longer periods of beam off after we started taking data to re-tune the machine and also due to FSD faults coming from an *increased* Hall C dump water flow (https://logbooks.jlab.org/entry/3606883, https://logbooks.jlab.org/entry/3607141).

As a consequence we fell short of getting the 65% of the desired stat. goal at  Q2=3. W=3.14 x=0.25 theta_Shms=12.42 deg and we only got 12% so far at Q2=3. W=3.14 x=0.25 theta_Shms=9.42 deg. For a status of data taken so far check https://hallcweb.jlab.org/wiki/index.php/Kaon_LT_Status_Page

We had to take a quick escorted access at the very beginning of the swing shift to reset the rotation controllers for SHMS and HMS https://logbooks.jlab.org/entry/3606658 and https://logbooks.jlab.org/entry/3606706

There will be an RC meeting today at 4:30 pm on the second floor of the counting house. Sylvester is the incoming Hall C RC and he will run the meeting.
