2 hour SEM time limit

I will loosen up the 2 hour time limit constraints on SEM sign-up time to 4 hours. The only problem we have ever had is when users block large blocks of time for several days during a week. We need to make sure that everyone has access to the SEMs when needed.

Remember that evening hours are available to unrestricted users (who have swipe access to the lab doors).

FIB status

A part failed in the deposition gun – the depo gun is unusable. I ordered the repair part but it might take up to 80 days to arrive.

The FIB can be used for milling but we cannot do any lift-out work until the depo gun is working.
