Afternoon, 

Hall A status is in a good state. Liquid are full and regulating, LN2 is good and power supplies are off. Robert is reducing our lead flow on his end because the Hall is inaccessible do to the tritium handling that's currently taken place. Once the Hall re-opens, I will go down and check vacuums and verify they are still good.

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.
