[Dsg-rich] RICH N2

[Tyler Lemon]

Hi Bob, 

Thanks for letting us know. Was this pressure gauge added to monitor the N2 pressure at RICH's gas panel? 

Just to make sure, I have verified from EPICS data that RICH's N2 volume humidity did not change during the two minutes with no N2 flow for the pressure gauge installation. 

Plots of humidity and N2 flow during the gauge installation are attached. 

Best regards, 
Tyler

Tyler, 

You may see a loss of N2 to the RICH for a minute while I add a pressure gauge. 

Call me at 822-9586 if you have any questions.
