The Tecnai T20 is a transmission electron microscope equipped with a thermionic electron source with a Lab6 filament and acceleration voltages that can vary between 80-200 kV. It has the FEI super-twin (S-Twin) pole piece with a pole piece gap of 5.2 mm (Cs about 1.35 mm). This gives the microscope a resolution @ 200 kV of 1.4 Å in TEM mode. Other tecniques available on the microscope are scanning transmission electron microscopy (STEM, resolution 10 Å) with a high-angle annular dark-field detector (HAADF).<br /> | The Tecnai T20 is a transmission electron microscope equipped with a thermionic electron source with a Lab6 filament and acceleration voltages that can vary between 80-200 kV.

On the analytical side, the microscope is equipped with an Oxford X-Max 80T SDD X-ray detector for Energy Dispersive X-ray (EDS) spectroscopy and a Gatan Tridiem 863 imaging filter allowing for electron energy-loss spectroscopy (EELS) and energy-filtered imaging. For imaging, the microscope is equipped with TVIPS XF416 CCD before the the energy filter and a GATAN Ultrascan US1000 after the energy filter.<br /> | On the analytical side, the microscope is equipped with an Oxford X-Max 80T SDD X-ray detector for Energy Dispersive X-ray (EDS) spectroscopy and a Gatan Tridiem 863 imaging filter allowing for electron energy-loss spectroscopy (EELS) and energy-filtered imaging.
