Most of the parts for the Langmuir probe are here.

The probe will connect via the rear 8″ conflat:

You can see the chamber is supported on either side by 80/20:

Stuart has the long socket wrench we’ll need:

We have ceramic tubes left over from the fusor grid. However, they don’t quit fit together.  I’ll have to file the smaller one with a diamond file. Easy.

An open question:
