[Esr-users] Halls A, B, C Cryo recovery after the ESR down

[David Kashy]

Hi All,
Hall B is on cold return but is not stable. We tracked part of the instability to poor insulating vacuum in the Solenoid 4K return U-tube. Denny and company are putting a pump on it.

After this is done it should help hall B stabilize and also help with Hall A recovery.

Dave
