We removed the 10" to 2.75" CF Zero Length Reducer Flange from the Laser Filter Cavity (LFC) Output Vacuum Cube and put it on the "output port" of the Demonstrator Interferometer Vacuum Cube. We cleaned the vacuum and surrounding areas near this output port on the cube before placing the flange.

We removed a 4.5" CF Window (presumably AR coated for 1064 nm light), wrapped it in a dried out clean room wipe that was previously wetted in isopropanol for UHV, wrapped that in foil, put it in an anti-static bag, labeled, and put it away.

We removed the 10" to 4.5" CF Zero Length Reducer Flange now with UHV foil where the window was previously attached, cleaned the flange, and placed it on the newly opened spot on the LFC Vacuum Cube.

I then tightened the bolts on these two 10" CF Zero Length Reducer Flanges to 34 Nm.

I hope to finish work on the LFC Output Vacuum Cube tomorrow, which involves cleaning the 10" to 4.5" CF Zero Length Reducer Flange outside from tape residue, placing a 4.5" blank flange, and adding the custom 10" to 8" nipple.
