E01 is equipped with a Gatan Quantum GIF for electron energy loss spectroscopy.

To acquire EELS spectra:

  1. Set camera length to 2.5 cm.
  2. Select 5 mm entrance aperture on EELS spectrometer.
  3. Select dispersion value required.
  4. Under EELS window select single and user profile.
  5. Ensure energy shift is at zero.
  6. Ensure exposure time <1x10-4 s.
  7. Start view and manually increase exposure time until ~1x104 intensity in the zero-loss peak.
  8. Adjust PL deflectors to maximise intensity of zero loss peak.
  9. Align zero loss peak (automatic procedure under "tune GIF")
  10. Adjust focus x, y and Sx , Sy of zero loss peak to minimise FWHM.
  11. Select dual mode and required collection profile.
  12. Once spectrum obtained highlight area around zero-loss peak, select SI menu and align SI by peak. This will realign all spectra to the zero loss peak position.
