TEM: Thermo Fisher Spectra Double-Corrected Transmission Electron Microscope

Main content start

Overview

SNSF is commissioning a new state-of-the-art Thermo Fisher Spectra 300 monochromated, double-corrected transmission electron microscope in January 2023. The main features of the TEM are:

  • Accelerating Voltages at 30, 60, 80, and 300 kV
  • High Brightness Schottky field emission gun ( X-FEG)
  • Monochromator
  • Cs CETCOR/S-CORR double correctors
  • Advanced STEM imaging, 4k×4k STEM data acquisition, EMPAD, 4D STEM
  • SuperX energy dispersive spectroscopy (EDS ) detectors
  • Ceta-S camera with speed enhancement capabilities
  • Gatan K3 camera for low dose imaging
  • Electron energy loss spectroscopy (EELS) with dual EELS GIF continuum spectrometer
  • TEM, STEM, and EDS tomography with acquisition, reconstruction (Inspect3D) and analysis (Avizo) softwares

Instrument Resolution:

  • Image resolution (TEM mode): 0.5 Å
  • Probe resolution (STEM mode): 0.5 Å
  • Energy resolution (with monochromator): 30 meV
