[dsg-hallb_rich] N2 bottle for RICH aerogel dryboxes

[Tyler Lemon]

Hello Bob,

Last week we had one of the RICH aerogel storage dryboxes fail. Fortunately, we've been able to relocate the aerogel in that drybox into the other two dryboxes. Since we're now storing aerogel at or even above full capacity of the two working dryboxes, if there's a problem with one of those, we would not have anywhere else to move the aerogel.

Because of this, could you put together a system with a nitrogen bottle to be able to purge the dryboxes with nitrogen?

The set up would be the same as we discussed back in October before the power outage in the EEL. I think all that would be needed is a nitrogen bottle with a regulator, relief valve, local pressure indication, rotameter, and the fittings to run a 1/4" gas line to the boxes. We already have a few feedthroughs that would be used to connect the gas line to the box.

At some point we may want to add remote pressure monitoring to the set up (we don't have the sensors available right now but may in the future), so if needed, please include those in the pressure system design.

If you have any questions or need any more information, let us know.

Thanks,
Tyler
