Subject: New vacuum system viewport design 


After conversations with Alastair and Steve, I have come up with the following design for the new (AR, wedged) viewports for the gyro vacuum system. I turns out that we already---for some time---have the optics (W2-LW-1-C-1064-0) and CF blanks that we need.

So, all we need to do is:

  • Get the CF blanks machined to have an O-ring groove on the outside, and get some threaded holes tapped in from the outside for the screws that will hold the window brace ring.
  • Get the window brace wing machined
  • Purchase/find the appropriate O-rings

A glance at the diagram below will make the above make sense.

I am going to talk to Mike Gerfen on Monday to see what he thinks.


 The plastic brace-delrin on the top has to function on the top: 1, hold the window in place at atm 2, keep dust-dirt  out.

The window should sit on a thin teflon gaskit on the vacuum side
