[Esr-users] HPC-2

[Jonathan Creel]

The lab has now moved us to HPC-2 and are now preparing for bad weather. 
Since we are already not running beam we are asking that the Halls not 
make any significant load changes such as charging Hall magnets or 
performing quench testing. This places higher demands on the ESR plant 
and raises the chances of a turbine shutdown. We are trying to stabilize 
the loads on the ESR so that we can shutdown the transferline and 
segregate the plants for added protection. If during the testing the ESR 
turbines or compressors are accidentally shut down it will be difficult 
with the manpower we have and the time remaining to recover all of the 
magnets and Halls before the bad weather arrives.

Please call me if there are any concerns or if you would need to discuss 
specific high value needs that cant wait.
