Dear Collaborators, 

This is to give you a quick update on the latest status on Hall C and the accelerator.

The good news on the beaker: the facility was able to source a refurbished breaker, and it will be ready to be picked up from Williamsburg tomorrow. If all things go according to the plan, we (all three halls) will take 12 hours of beam from Tuesday 8:00 pm to Wednesday 8:00 am. Wednesday will be a maintenance day for the accelerator to further complete the breaker work. 

Hall C is currently under restricted access. A series of maintenance work was completed including: SHMS rotation camera, HMS dipole NMR fix, Raster magnet power supply restoration. 

Outstanding issues: 
1. Target Fan controller will be worked on by Dave this afternoon, or tomorrow morning.
2. Joe attempted to fix the target ladder camera. He identified that the camera need to be replaced. He will wait until the next funding cycle (start in a few days) to buy the camera.
3. Tune mode generator work will be done parallel to the breaker work tomorrow.

Hall will remain open until before the beam delivery tomorrow (6 pm). All maintenance work should be completed by then. We are not planning to open the hall on Wednesday. 

Leader shift is now canceled until 4 pm tomorrow; TO shifts are unchanged.  

Many thanks
Bill
