We are going to bake the gun chamber overnight, so the microscope cannot be used. It should be up and running tomorrow morning by 10 am.
FE-SEM in Electron Optics
The field service engineer will install a new objective aperture in the FESEM this morning. The scope should be back online after lunch.
I’m having service done on the FESEM EDS detector over the holidays. It should be back online before the semester begins.
Please plan accordingly.
Just to clarify, the FESEM will be usable while the EDS detector is being serviced.
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.
I’ve put in call for help. I”ll let you know when its back online.
There have been a few problems getting thumbdrives to eject on the FESEM PC. What I did that worked is to make sure that Explorer is not pointing to your data on the FESEM PC, then highlight your USB drive in the list, right click and select Eject.
The monitor failed on the FESEM and I moved one from another lab. Only problem is that it is a wide screen. Images on the monitor appear stretched but the images you save will not be stretched. We will receive a proper replacement tomorrow.
We are seeing some yellow spots in dark areas on the FESEM screen, but they go away before acquiring an image. Let me know if you start seeing distortion in your acquired images. I’ll work on getting Hitachi service here to repair.
I’ve repaired the EDS and it appears to be working correctly now. I’m watching it for signs of the original problem.
There is a problem keeping the EDS online. I am waiting on a repair part now.
