First Half of HAM1 table cleared

[Betsy, Camilla, Elenna, Oli]

We cleared half of the HAM1 table today on the +y side. This cleared optics on the ALS and POP paths, and the first part of the optics on the REFL path. We carefully labeled each component, and Oli logged component and cable names with serial numbers. Betsy laid the components in clean pans lined with cleanroom cloths. The cables are still attached to the feedthroughs and were left lying at the bottom of the chamber.

Attached photos show cleared side of the table.

Before removing components, we reviewed the table layout after Ibrahim and TJ noticed some discrepancies between the solidworks drawing and the optic locations as depicted in Corey's pictures from yesterday. We confirmed that there are some dispcrepancies between the two. TJ has a more detailed report.
