[dsg-svt] [Dsg-rich] Nitrogen system

[Marc McMullen]

Hi Valery, 

I spoke with Tyler earlier and he is aware of the situation. Currently, he says there are no adjustments needed. However, he is monitoring the situation and we can adjust or advise Hall B if necessary.

Hi Marc, 
Do we need to do something with RICH due to this exercise? 
Best, 
Valery

Hi Morgan, 

I am forwarding this to the detector groups which utilize the nitrogen 
system, so that preparations can be made if necessary. 

Regards, 

Marc

The pressure changes are expected to be in the 5-10 psi range. At the end of the aforementioned rebalancing, there may be a slight increase in the pressure of the Nitrogen going to the hall. The said increase may be around 5 psi, maybe less, maybe a psi or two more.
