Logentry Text:
We got beam back yesterday around 7 pm after the restricted access. We started the optics run plan posted here: https://hallcweb.jlab.org/wiki/index.php/RC_Meeting_and_Run_Plan,_Thursday,_February_12#Current_Run_Plan

We still have the F2 yptar scan left to do and some of the single arm J/psi commissioning running. 

Past 1 am last night we had to take an escorted access to reset the rotation controllers for both spectrometers.

Beam was less stable than previous nights, at some point MCC limited us to 40 muA due to excessive beam trips.

This morning we went to restricted access to allow work on the new HMS Q2 power supply. 

We also rotated the SHMS to 13.1 deg. We can rotate to larger angles remotely but we cannot rotate back to 13.1 deg remotely (this would have to be done from the Hall with Steve Lassiter and spoters).

Holly will take over as RC after the 1:30 MCC meeting.

We will meet today at 4:30 pm on the second floor of the counting house. Here is how to connect:
