Abstract:
Results on a pilot test for an Exchange Gas Guard at Stanford university. To be presented at the LVK meeting (March 2020)

The simple design can hold a pressure differential to enable the use of exchange gas for initial cooldown on cryogenic GW observatories. More tests and engineering can be applied for real scale prototypes.
