Just a quick update. The sputter coater stage has been repaired. It is available in sample prep. As always please be gentle working with this instrument. Also, do not put carbon tape directly on the stage.
Specimen Prep in Electron Optics
The stage for the sputter coater has been sent out for repair. If you need to sputter coat your sample please let me know.
Just letting you know I put the TEM grids back in my office (MM622).

If you are ever going to need TEM grids while I’m on vacation (Aug 2-30), please take the TEM grids in the glass desiccator at the MM631.
Please, make sure you follow the TEM Grid Instructions.

This is to inform you about the recent updates made to the SEM sample coating procedure in order to streamline the process and enhance its efficiency.
To have your samples coated, please drop them off at the image analysis lab (M&M 631) in the designated desiccator. Samples should be labeled with your name, email address, and any special instructions. If necessary, you can find labels within the desiccator. Labeled samples should be placed in the intake section of the dessicator. Once samples have been left, please fill out the Training/Coating Questionnaire to notify ACMAL staff of your sample.
Allow 2 days for us to coat your samples. Once completed your samples will be returned to the desiccator on the “Ready” shelf and we will send you an email.
ACMAL recently installed new recycling infrastructure across the seven labs on the 6th and 7th floor of the M&M and the STEM lab at the ATDC.
Please review the new Recycling section in ACMAL Cleanliness under Policy.
I was able to replace the rod and the issue is resolved.
Please don’t ever force anything on the microscopes. If there is an issue you can call me. If I’m not available you can send me an email and I will take care of it as soon as I can.
The FESEM is down. The specimen exchange rod has been bent making it almost impossible to load a sample.
At long last the new Pt/Pd target has arrived and we can return to the normal operating procedure for the sputter coater. I’ve installed and tested the new target.
The Cr target isn’t coating well and users are experiencing charging issues. I’ve changed the target material to Iridium. Please use the settings below.
Target density: 22.42
Current: 20mA
Coating thickness: 1-3nm
The new target is scheduled for shipment and should be arriving soon.
If you have any questions please let me know.
