[Esr-users] SHMS loss of vacuum

[Steven Lassiter]

The SHMS transfer line experienced a loss of vacuum yesterday when a pump was removed and the vacuum actuator did not close properly.
The insulating vacuum spoiled and the excessive heat load resulted in the all magnet, HMS and SHMS, losing He and LN2 inventory. Magnets are warming up.

Working to recover the HMS while taking the SHMS off line.
Work in progress.
