[Esr-users] Nitrogen Supply Shutoff Friday 9-20-24

[David Kashy]

Hi All,
Please check your systems to verify that they stay above 1 atmosphere to ensure that no lines are plugged due to moisture condensing from back flowing vent lines.

Brendan,
Do you know when the last time the O-rings at the N2 vent check valves at ESR were replaced? Might this be a maintenance item to put on a schedule?

Dave

Good morning,

At 0830 on Friday, 9-20-24, Cryo will be tying in the new nitrogen dewar via u-tubes. The nitrogen to ESR and the halls will be shut off for about 30 minutes during this operation. If there are any issues regarding this plan, please email me.
