Same problem with gun alignment error. I’ll work on it tomorrow morning.
Danielle got the ion mill back online. Ready to use.
Yoke Khin Yap, professor of physics at Michigan Tech, led the study. He explains that the behavior his team observed — atomic-level manipulation of gold quantum dots — can be seen with a scanning transmission electron microscope (STEM). The STEM’s high-powered beam of electrons enables researchers like Yap to watch atomic movement in real-time and the view reveals how gold atoms interact with the surface of boron nitride nanotubes. Basically, the gold atoms glide along the surface of the nanotubes and, they stabilize in a hover just above the hexagon honeycomb of the boron nitride nanotubes.

Atomic Zoom: Michigan Tech’s Scanning Transmission Electron Microscope
Paul Sanders, Patrick Horvath Endowed Associate Professor of materials science and engineering, and materials science and engineering graduate student Yang Yang, are trying to strengthen aluminum by adding scandium to it.
The aberration-corrected FEI Titan Themis scanning transmission electron microscope (STEM) in Michigan Tech’s Applied Chemical and Morphological Analysis Laboratory, makes an electron beam less than an atom in width. This allows researchers to scan through samples one atom column at a time. Additionally, the lab has a SuperXTM X-ray detector, which is an array of four detectors to collect four times more X-rays than a conventional detector.
Combining the two techniques, researchers can element map at atomic resolution.

Shouldn’t be a big deal. Waiting on call from company.
I got the system working again this morning. It is okay to use it. The problem was that the gun alignment would go wonky and signal would drop to zero – no SE image. If you see anything like this stop and let me know.
There is a problem with the gun alignment circuit. I let you know how the repair goes.
And ready for use.
The water pump is repaired and the system is pumping down overnight. Should be ready tomorrow or Monday. I’ll let you know when you are free to use it.
I had trouble replacing the water chiller motor. I ordered another that will be here Wednesday. I should get us back online then.
