I do not know what happened this morning. The engineers gave me a suggestion, but it worked before I tried it. I fear that the problem may return. It appears as many diagonal lines at focus. See the attached image.
Let me know if you see anything unusual.
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.
I’ve put in call for help. I”ll let you know when its back online.
