My apologies Chris. Yes, last night around 0130 we had a Qdsum trip of the solenoid magnet resulting in loss of cryogen in the magnet reservoir. The lack of emails was an over site on my part. I will make it a habit to start those at the onset of a problem.
Thanks
Denny

Subject: [Esr-users] Hall B solenoid issues
At about 1:30 the Hall B solenoid had a problem that caused it to lose liquid level. Events like this have a big affect on ESR and it would be good to notify cryo via this mailing list or direct email to myself with a brief description of the issue.
