Hi Everyone, 
        There has been steady progression through the kinematic settings since yesterday. We are currently finishing setting: 3.3.9
       Setting 3.3.9: 
       SHMS @ 8 degrees (-9.2 Gev) and HMS @20 degree (-2.71)
      After Setting 3.3.10, the plan is to do:
      1.) Target boiling 
      2.) Positions

Which will conclude the run plan for Setting 3. 

Additional Notes:
*There will be RF recovery tomorrow. The hall will go to controlled access so that the techs and others can check on things (downstream vacuum pump, etc....)

*During OWL, the HMS Q1 interlocked. After reseting, it continued to interlock. See Casey's entry for a detailed description: https://logbooks.jlab.org/entry/4096910

It seems there is some noise that is causing it to interlock. The magnet on call was able to make some software changes so that it wouldn't interlock on the noise and we could continue running over night, but it is something that should be looked at when there is access to the hall.  I will check with the experts to see if they need to access to the hall today or if they would like to wait until tomorrow during RF recovery. 

Let's have a brief RC meeting today at 11:00 pm to discuss the upcoming run plan and plan for any other activities in the hall tomorrow during Controlled access. 
Best Regards,
Mike Nycz
