Here are some closeups of the gate/pump mount:

I wonder what that small portal on the top is for?

This looks like a conflat on the side you can’t see:

You can see a ring where the rubber gasket from the pump would go:

But how do I attach the pump? Where do the screws go?

Just confirmed: All the smaller portals on this vacuum chamber are ConFlats!

Today’s TODO list. 

1. catalog portals
2. purchase missing portal covers (blanks, view portal, HV feedthrough, gas feedthrough)
3. are any of the portals conflats?  YES. all the smaller portals are conflats.
4. Purchase rough pump  rough pump
5. remove guts from lid
6. clean chamber
7. what’s the deal with the vacuum meter (supposedly one came with chamber). Only measures down to 10e-3 torr.
8. get controller for turbomolecular pump 
9. get oil for turbomolecular  pump
10. try to attache turbomolecular  pump to chamber need to get a new pump or a huge elbow!
