[dsg-hallb_rich] [EXTERNAL] Re: RICH Aerogel N2

[Marco Mirazita]

Dear Tyler, Brian, Bob,
thank you for pointing out this issue and for considering possible 
solutions.
However, the tiles are sealed in individual plastic bags, therefore they 
should survive the 10 hours power outage foreseen without any damage. 
And any possible, and most likely very small, humidity absorption, would 
be recovered once the power is back.
Therefore I believe there is no need to set up an N2 flow system for the 
dry boxes.
Best regards,
Marco
