[Jeff, Daniel]

I moved the "output" Laser Filter Cavity Cube closer to the edge of the table so that we could work on it more easily. Jeff and I took off the 10" CF flange with an angled 2.75" CF flange off the cube, wrapped it in foil, and put it away with the other holometer parts. I didn't like this flange as it stuck out past the custom aluminum base and didn't seem very useful. In its place, we moved the 10" CF flange with two 15 pin D-Subs from the top to this location (this flange will be facing South when the cube is placed back). We moved a 10" to 4.5" zero length reducing flange from the side to the top. In that place, we added a new 10" to 6" zero length reducer. I believe we match up the hole pattern so that the 6" to 2x2.75" reducer will have the windows 5" above the cube bottom as designed.

I cleaned parts of the cube and the flanges with the Wipes rated for cleaning UHV, but the surfaces were pretty clean to begin with.

We only tightened the screws so that the washers couldn't move. I still need to tighten the screws to compress the copper gasket.
