Today's activities:
- HAM3 was prepared for door removal: the AIP was valved out, and the Annulus system was vented with N2
- EX was fully prepared for pumpdown, which happens next week
- RGA at EX was finished, it's totally leak tight - although its Ion-pump needs some troubleshooting
- There was a solution found for the filters' installation to the Hepta headers: the ISO-fitting will be done with a unique part (https://ancorp.com/product/4500060/), as the more standard claw clamps cannot be fit there
- The 2nd bellows for the relay tube was located - it needs class-A C+B
- Dew points were measured at the corner and at EX, all is good: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=75590
