Vacuum Chamber Acrylic Window Finished!

I was up at the university and finished the front acrylic window:

The seal is pretty good, although I will likely need clamps to get it tight but once under a vacuum, the external pressure should seal it.  I also attached the portal on top and still need to find caps for four of the smaller holes.  I haven’t figured out how to get the coax cable into the chamber yet…  I will be back up at the university next week.
