| Status | Run 74 in progress. Warmed up after 3rd appearance of IVC leak at 4K. Cryostat Vacuum Jacket pumped out. All IVC sections and stripline tube have been removed. |
| 1400 | New Viton o-rings arrive, not the Aflas ones. The Viton ones already look better - the ones we use before have a seam on the inner edge from injection molding or something. The new ones don't have this seam. |
| 1500 | Spend a while sanding the inside of the stripline tube port through the fridge flange. As noted before, there are bumps here, weld joints, which seem to produce scratches on the stripline tube. Hard to sand these bumps away completely. |
| 1530 | Clean off various surfaces at and around the stripline elbow with methanol. |
| 1600 | Remove the MB seal o-ring from the stripline tube port, working it all the way down along the striplines. |
| 1615 | Put a layer of Kapton tape around the inside of the stripline tube port. Maybe this will protect the tube from getting scratched.
 |
| 1655 | Sand the inner surfaces of the holes in the metal fridge baffles that the stripline tube goes through. Then try putting a bunch of little pieces of Kapton tape around the inner surface, again to protect the tube from getting scratched.
