[Esr-users] ESR load

[Denny Insley]

Good afternoon All,

    Hall B is currently running on 12 to 13 g/s of 4K flow to maintain our magnets.
The Torus and Solenoid have been ramped down and the power supplies locked out. The 
supply valve from our 500L dewar to the Saclay cryo target has been closed.

Hello Dave,

As a follow-up to Robert Norton's message, here is the context.
Traditionally with no 15K target online, ESR without assistance from CHL1
can support all 4.5K magnets in Halls A, B and C, which was confirmed during
the holiday period that started at the end of December 2017. 
As part of hurricane preparation, the goal to secure CHL-ESR 4K
transferline, but the unaccounted load increase is disallowing the stoppage
of 4.5K flow from CHL1 to ESR.

Thanks!

Good morning,

We are seeing that even with ESR at full power, the plant can't seem to keep
up with the current load without assistance from the CHL-ESR 4K
transferline.

If there are any unneeded liquefaction loads from 4K to warm-return, we
would like to minimize them at this time. Please check and respond back if
you can.


Thank you for your time, and have a wonderful day and a safe week.
