Next week, Oxford will be on campus to improve the connection between SEMTech and Oxford. If you have experienced any issues using the ESEM, please let me and Isabella Jaszczak know.
I have discontinued the “Intake Sample Request” form.
If you are a certified operator of the FEI Titan STEM, please fill in the “Independent Usage Request” form available through this webpage:
If you require staff operated analysis fill in the “Request Analysis” form available through ACMAL webpage https://www.mtu.edu/acmal/

The O2 meter at the STEM lab is inoperante. We are now using a small hand size backup O2 sensor (see picture) in the STEM lab. It’s on the window stool.
If it reads 24 it means the oxygen level is normal.
Please, do not remove this oxygen sensor out from the lab, and leave it next to the window so it’s visible from outside.
If it flashes and beeps please leave the room and let me know or ACMAL staff know.

As a kind reminder, please use the following text when you acknowledge the ACMAL in your publications:
“The electron microscopy research was performed at the Applied Chemical and Morphological Analysis Laboratory at Michigan Technological University. Electron Microscopy facility is supported by NSF MRI 1429232”

The reservation calendars for the AFM and FIB will no longer be merged. We’re splitting these two calendars. It’s important to note that this is a shared space, and both instruments might be in use simultaneously. If your research is highly sensitive, please make sure to book the room on both calendars.
The new calendars will be named:
- ACMAL-Origin AFM
- ACMAL-FIB
Let me know if you have any questions,
The 6th floor computer lab will be closed for the rest of today and tomorrow until 1 p.m. We will be conducting a site survey, so please do not enter the lab.
The FESEM EDS system has been repaired and is available for use.
My apologies for the delay in repairing this detector. The original manufacturer has gone out of business so we have to work with a third party company which has limited availability.
The ESEM is functioning well. However, the instrument is not connecting to the internet. IT is aware of the problem and working to resolve it.
October 4
This issue is resolved. If you have any trouble with the ESEM please let me know.
October 3
Due to alignment issues with the beam on the esem we are not able to get high enough counts for EDS. Please take this into consideration while planning your usage. I am working with SEMTech to resolve this issue.
The ESEM is back online.
