[Dsg-rich] Back-up N2 system components for RICH

[Tyler Lemon]

Hello Bob and Dave, 

For RICH, the nitrogen purge is used to keep the aerogel tiles inside RICH in a low humidity environment. If the aerogel is damaged due to moisture absorption, RICH will not be able to operate properly. 

Could we arrange for an approved regulator and components to be on hand to be able to switch to a nitrogen dewar or bottle for RICH in Hall B in the event that Hall B's main nitrogen supply goes down? 

As system owner and Design Authority for RICH, we would need to get the list of components and the approval from you to use this back-up system. 

Please let us know how we should proceed in order to get this back-up nitrogen system ready for RICH. 

Best regards, 
Tyler
