Technical Notes

Resolution

• Electron beam:
  • At optimum WD: 0.7 nm at 1 kV • 1.0 nm at 500 V (ICD)
  • At coincident point: 0.6 nm at 15 kV • 1.2 nm at 1 kV

• Xe Ion beam resolution at coincident point:
  • <20 nm at 30 kV using preferred statistical method
  • <10 nm at 30 kV using selective edge method

Attachments

May have: (need to check)

- Thermo Scientific CryoCleaner Decontamination Device

- WDS

- EBSD

- Retractable low-voltage, high-contrast directional solid-state backscatter electron detector (DBS)

- Elstar Column in-lens SE/BSE detector (TLD-SE, TLD-BSE)

To find the basic instructions for operating the instrument, the reader is referred to the labmanager manual.

Important Notes

• ALWAYS make sure the EDS (and EBSD relevant?) detectors are RETRACTED when opening and closing the chamber.
• Do NOT adjust the Nitrogen regulator!!! Relevant?
• Always open and close the chamber GENTLY whilst viewing the live CCD image.
• Only home the stage with open door or if in vacuum only with holders that you are 100% sure it is safe to do so.
• Make sure you delete all saved positions before finishing your microscope section.
• When moving between saved positions, BE CAREFUL! If you are unsure move the Z height to the lowest point and lock it so as not to collide with the pole piece.
• Use the logbook
• NEVER work without a valid link between the Z and the FWD
• ONLY INSERT EBSD CAMERA if the sample is at the correct position (in case of a special EBSD holder the stage must be tilted to 16 °). Relevant?
• Always use GLOVES. Only vacuum-ready samples and holders are allowed inside the chamber.
• DO NOT install ANY software on either the microscope or support PC,.
• Transfer your files at the end of each session. We will be deleting files from the support computer without notice.
