We continue cycling the 3He/4He targets according to the run plan.

Overnight we had some cryo issues correlated with the magnet incidents in Hall B. In particular the HMS Q3 and Dipole interlocked https://logbooks.jlab.org/entry/4127808   Joe and Heidi responded to our calls to properly recover the HMS magnets https://logbooks.jlab.org/entry/4127837. Basically, we had to wait patiently until flows were stable.

Simultaneously, we had cryo incidents with our target that warmed the loops 1 & 2  https://logbooks.jlab.org/entry/4127813 
JP guided us to recover the target status, and similarly we had to wait  patiently until flows were stable.

Ops is working on finding  the best plan to keep the machine running over the weekend. 
They took the beam away and will run some tests, then reconvene at about 2 and 3 to find the best path forward.

It is possible that we will have RF studies on Wed. or Thur. next week, keep tuned for more information.

No RC meeting today. I will keep sending daily updates over the weekend.

Thank you to all our shift workers and crew for keeping the experiment up and running as best as possible. 

Have a good weekend.
