[Esr-users] No Recovery Compressors today and tonight

[Dave Kashy]

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
