Summary from the past 24 hours:

Overall quite smooth running, 1.136 C (polarization corrected) accumulated on Sunday alone, and over 4C accumulated since Friday.

Info: 
* There will be beam studies on Wednesday, so we will go in controlled access. By then, please inform me if you want to do any work (I already know the GEM group wants to go down there).

More good news:
* There was an issue with the beam dump vacuum pressure: https://logbooks.jlab.org/entry/4199752
=> this issue has been partly solved https://logbooks.jlab.org/entry/4200261#comment-46301
Still discussing with the competent people if it needs additional investigation
* I've been informed by the program deputy that the authorizations needed to operate the accelerator at higher energy were obtained. In other words, we shall be able to request even higher current. 

Issues: 
* Accelerator: Arc 3 shunt MXW5R03 mismatch: https://logbooks.jlab.org/entry/4200078 => 4h down
* Beam window cooling jets dropped https://logbooks.jlab.org/entry/4200498 => 1h down
Thank you Todd to come at night to solve the issue https://logbooks.jlab.org/entry/4200511
* GEM trips;
* Occasional DAQ freezes;

We will have the regular RC meeting at 3:30pm in the Counting House conference room.
