Due to scheduled accelerator maintenance work and injector High voltage trip problems, we did not have beam during yesterday Day, Swing and part of the Owl shift.
We got beam back around 3 am in the morning.
The injector was tuned for A2 aperture intercept issue and MCC recycled many magnets and adjusted the gang phase.
After all of these we have better Compton background rates and the fast-feed is way better than what we had yesterday.
We have quickly checked our detector alignment - it's position looks similar to where we left before the lock-down.
We have a few hours of production from this morning. 

Right now MCC is trying to tune through the Compton chicane.
If that goes well we will commission the Compton polarimeter.

We will have our remote RC meeting at 3:30 PM to discuss the run plan.
