Raith EBL Update
Raith replaced every item that was left to replace in the column on Monday. Yesterday they performed some quick tests @ 50kV and the issue with deflector settling was gone. This is an extremely positive result! It almost certainly suggests that the issue has been repaired. However, tests @ 100 kV remain to confirm the behavior and we are doing so later today and early tomorrow morning.
I am pretty confident that we are going to have a fully functional EBL system available for use early next week!

Suss SB6-8E
We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests.
I will send out an update once we have one.

The board we were waiting on arrived, but it did not resolve the tool issue. We are working with Panasonic on the next steps.
