[Esr-users] Hall A Cooldown Update

[Jessie Butler]

Good Morning,

Currently the average temperatures in Hall A magnets are: Q2s~110K, Q3~115K and Dipoles~105K. We have seemed to reach our limit for cooling until we are able to start missing 4K gas. I briefly spoke to Chris about this and he advised me that that it maybe possible for us to start the 4K mix on Monday. Does anyone foresee and issue with us starting the 4K mix on Monday? Please note that this will be done under the already established guidelines that Halls B & C have the priority.

Thanks,
