The dome was returned to BSC-7 this morning. During the inspection of the dome flange o-rings, a fiber (saved) was found and removed. Kyle came out and took a look at the fiber and told the crew what to beware of, etc.  Since no further issues were encountered, the dome was put in place and secured.

After lunch, Mark L. and I went into the chamber to remove the dust barriers, inspect the beam tube convolutions, and vacuum them if needed. We did end up vacuuming with the LLO-designed bellows vacuum attachment. Mark also inspected the floor on the way out of the chamber and removed a couple of "spots". 

The final planned activity of the day was replacing the door on the chamber. The door interior was inspected once it was inside the cleanroom. The welds were not nearly as bad as those in the dome and the door body was not very dirty either (neither left much visible residue on a clean glove, even with a couple of attempts). The decision was made not to do any vacuuming or wiping on the door, but to leave well enough alone. The door was replaced and secured.
