EY closeout

Margot and I performed all of BSC10 closeout tasks listed in my previous alog regarding this closeout. We pulled the FC from the ETMy optic a little after 11am, and the door was going on at ~1:30. It took "so long" (ha) because we ended up having to spend some extra time calling in the troops about one of the ISC viewports having what appeared to be a scratch on it's inside surface. More details to come as needed.

Here are some further pictures of the ACB swing back and the FirstContact spray cone attachment to the HR side of the ETMy QUAD structure from yesterday. Yes, the cone protrudes into the baffle. Yes, Margot still was able to fit her head and an arm with the spray bottle in the cone.

The last picture shows the placement of the horizontal wafer and verticle 1" witness optic in the center of the chamber, placed today just before the door went on the chamber.

4. Horizontal wafer on floor under quad:T1400250 placed at end of closeout.
5. Horizontal 1’’ optic: T1400251 was left on beam tube floor between BSC10 and BSC6. Looking up SN/history. Didn’t take it out, because we had no clean optic containers handy.
