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:
- Information Limit (TEM mode): 0.7 Å
- Probe resolution (STEM mode): 0.5 Å
- Energy resolution at 300 kV (with monochromator): 110 meV
- Energy resolution at 60 kV (with monochromator): 20 meV
