[Dsg-rich] N2 Filters

[Amrit Yegneswaran]

marc informed me that both the new N2 filters---the additional filters to ensure aerogel quality is not degraded, are leaking. 
Eli, Eli, lema sabachthani? 

george/marc please buy different, new filters ASAP. 
we should have the new filters installed before the aerogels are installed in the RICH. 

in the interim, if marco wants to do some tests with the nitrogen, we'll run the system without the additional filters.
