As a result of Dr. Koubek’s email to campus regarding the Governor’s executive order, I am cancelling all use reservations in the calendar this afternoon. We will be ready to begin again after we return from the stay at home 3 weeks from now.
Specimen Prep in Electron Optics
I will be out next week but I’ll mostly be in town. I could come in if needed. Aleister will be here working working 2 hours each day for coating samples and helping users. He plans to be here at midday.
The labs will be open all week between 8 – 5 and restricted users will work then. Unrestricted users have 24 hour access. Newly trained users, please work while Aleister is at work in case you have trouble.
Call Aleister or me if you have trouble. Aleister 520-576-3557. Owen 906-369-1875.
We have 3 stainless steel dewar tanks for dispensing liquid nitrogen in room 637 (Sample Prep). One of them has had a leak and was unusable for several months. I repaired it yesterday. If you find that the dewar in the outer room is empty get the 2nd one in the back room. There is no need to take the hose off of the 2nd dewar any more.
We will check parts inventory Monday.
I installed the new Pt/Pd sputter target today.
The PtPd target wore out this morning. I have a new one on order. In the mean time we are using the iridium target. You won’t be able to tell the difference with the Ir coating.
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.
Both cordless drills are missing from the tool chest and no one has signed them out in the logbook. Please return right away – someone else needs to use one.
Danielle got the ion mill back online. Ready to use.
Shouldn’t be a big deal. Waiting on call from company.
