HAM1 Before Photos:  (HAM1 chamber open just under 90min for this activity)

This morning before the deinstall activities begin, took the opportunity to photo document the HAM1 optical layout.  Keita requested I take photos to record the layout wrt to the iLIGO bolt pattern, because rough alignment of optical components on the new SEI ISI for HAM1 will be done utilizing the bolt patterns of the Optics Tables; so I took a few more photos than normal (top view and angled with a focus on the REFL path).  Took large photos with the Canon 60D DSLR camera as well as my camera phone.  

The photos are being populated in this Google Drive folder:  https://drive.google.com/drive/folders/1yDKp7aByA_TYJ12c8j8BnZM_pd1Q2DBZ?usp=sharing

Naming each photo referencing an updated layout Camilla Compton made which labels all beam dumps, but I also had to use an older layout to preserve naming since the layout on HAM1 currently looks like D1000313v16 (which is also referenced for naming the photos).

The above folder has the Canon photos, and I'll be adding the camera phone images next.

Contamination Control Notes:

• Dust Monitor on the West side of HAM1 had 0.0 counts (0.3+0.5um) BEFORE the work started and AFTER the work was done the counts were under 100.0 counts (0.3+0.5um).
• Travis touched up the Purge Air a little before the covers were rolled down.
• The Contamination Control wafer roughly in the middle of the table was pulled out and Betsy encapsulated in a container.
