Electropolishing

Please do not electropolish on the weekend alone. Also, if you only occasionally use it please do the work during the week in case there is a problem. We want to avoid equipment breakage.

Also, the LN2 pump gets condensation in it and freezes. If it is working right the hose black hose will freeze and the temp will go down pretty quickly. Turn off the pump and come get me to help if the pump isn’t turning.

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).
