(The above link is editable by the LVK. Please copy the slide over to your own google drive before editing. Just in case, Jeff is keeping a primary copy completely seperate and restricted from the one shared. Also note that the optical layout and vacuum chambers are built in to the slide as a part of the "theme" so that you can remove / add any labels you want. To access/change that core drawing, go to the "view > theme builder" and select the THEME page.)

Notes and Changes:
-v10 Corrected HAM6 ISI; it's only a "HAM-ISI + HEPI;" was correct in -v8, was just an oversight in -v9's complete recreation.
-v9 Per O4C upgrades, HAM1 seismic isolation changed from passive stack to ISI, POP path has now been added to call-out new PM1 suspension. Added a bit more legend, given now there's more than one periscope. Added laser enclosure. Converted source to using google slides rather than Omnigraffle.
-v8 minor correction to the location of SQZT7 and SQZT0.
-v7 now includes laser tables.
-v6 now includes new suspensions installed for the squeezed light injection system for O4.
