Unfortunately, the ESEM is still offline. We believe the problem has been identified. Hopefully, Thermo Fisher will be able to ship the part this week. Once the new part has been installed I will know more.
Thank you for your patience,
ESEM in Electron Optics
The EDS system on the FESEM is not initializing. I’m working with a technician to solve the problem. The FESEM is still available for high resolution imaging.
The ESEM is offline due to issues with the power supply. We are working with the manufacturer to correct the issue.
The ESEM is back online and available for use.
The ESEM is down. I am working with FEI to diagnose the error.
The roughing pump has been repaired. The ESEM is back online and can be used. The instrument still needs a full alignment, which won’t be completed until later today.
The ESEM is down due to an issue with the roughing pump. I will look at it this afternoon. I hope to have it back online soon.
The filament on the ESEM burned out. Once it’s cooled Dan will replace the wehnelt. If all goes well it should be available for use later this afternoon.
The EBSD detector repairs have been completed. Please contact ACMAL staff if you would like to use this functionality.
The EBSD detector on the ESEM has been damaged and the phosphor screen will need to be replaced. We are in contact with Oxford and hope to have the repairs completed in the next few weeks. The ESEM is still available for SE/BSE imaging and EDS analysis.
Please remember EBSD is only to be performed by highly-skilled, trained users who have been trained by ACMAL staff to use the EBSD detector. This is a very sensitive process and the detector can easily be damaged. Users with large SEM samples also need to be careful not to hit the detectors. Repairs are costly and result in instrument downtime.
