Hi,

 Hall C is prepared for the no recovery compressor.

Hi Chris P and Joe W, Jessie B and Steve L,
When we all agree we are ready we begin the switch over to Hall B Pressurization.

First shut
MV6010A 
MV6010B

followed by MV6030

and the make sure the following valves are all open

MV6030A,B,C
MV6031A,B,C

Once those operations are all done and it has been confirmed with me then finally close
PV60DLP


Hall B pressurization is setup to start as soon as all the above is complete. I may need to fine tune it when I see how the pressurization PID control responds.

Call me on my cell if you need to talk
757-876-3265
Dave

Hi All, 
This is a reminder that cryo will shutdown the recovery system this morning. It should be back up tomorrow sometime.

I will setup Hall B to pressurize the warm return line of all 3 Halls ABC to 1.1-1.3 atm.
Halls A and C will have their 4atm warm helium isolated.

When primary operators of the Halls get in this morning please start real time plots of at least 1 pressure in each magnet ( and other systems if you have any, such as dewars). This will assure us that all systems are being back fed with helium.

This recovery work presents a perfect time to do our Physics Division helium leak rate test. Please let me know who can support this work from each Hall and I will work with those folks.

Thanks 
Dave
