Ed, Sheila, Hugh
Today I removed the following from HAMS 2&3: ( all iris positions were photographed for convenient visual reference)
- MC1 iris (HAM2)- added an upside down dog clamp to mark position. Removed iris/post/fork w/bolt
- MC2 iris (HAM3)- removed the combination of fork clamps/spacer (w/bolt) that were constructed to hold the post. Left the upside down dog clamp installed.
- MC3 iris (HAM2)- 2 photos were taken of this position and no extra markers were added as it sits centered on a table line in front of it's baffle aperture. Iris/post fork clamp w/bolt removed
- MC3 Trans iris (HAM2)- 2 photos were taken of the two dog clamps used to position the fork/bolt was removed and the two upside down dogs remain.
- PRM iris (HAM2)- multiple photo angles were taken as this post doesn't center on anything of significance and getting an upside down clamp wasn't doable. Iris/post fork clamp w/bolt removed
I got approval from Sheila and Hugh to leave the marker (xxxx640 type) for MC1 iris. It was the only other position that I could fit a clamp against.
The half-wave plate was still in-chamber when I left the area. It will come out as well. ISS work in that area of the table and too many bodies prohibited me removing it at this time. Sheila may have removed it. If not, then I will in the morning.
I was informed this morning that the 1/2 wave plate was, in fact, removed from the chamber.
I did pull the half wave plate out of the chamber. After talking with Betsy, we need to double about the dog clamps to make sure we are creating anything that interferes with SLC.
