The Titan ETEM is a transmission electron microscopy equipped with a field emission electron source, a monochromator and an aberration corrector on the objective lens. This gives the microscope a resolution of about 0.in TEM mode. Other tecniques available on the microscope are scanning transmission electron microscopy (STEM, resolution 1.4 Å) with both high-angle annular dark-field (HAADF) and bright-field (BF) detectors. On the analytical side, the microscope is equipped with Oxford X-Max 80T SDD X-ray detector for Energy Dispersive X-ray (EDX) spectroscopy and Gatan Tridiem 966 imaging filter allowing for electron energy-loss spectroscopy (EELS) and energy-filtered imaging (EFTEM). For imaging, the microscope is equipped with Gatan US1000 cameras before and after the energy filter, as well as a Gatan OneView camera for fast ''in situ'' acquisition (25fps full resolution 4k x 4k, 100fps 2k x 2k, 200fps 1k x 1k).<br />
The Titan ETEM is a transmission electron microscopy equipped with a field emission electron source (FEI X-FEG), a monochromator and an aberration corrector on the super-twin (S-TWIN) objective lens (CEOS CESCOR). This gives the microscope a resolution of about 0.8 Å in TEM mode. Other tecniques available on the microscope are scanning transmission electron microscopy (STEM, resolution 1.4 Å) with both high-angle annular dark-field (HAADF) and dark-field (DF)/bright-field (BF) detectors. On the analytical side, the microscope is equipped with Oxford X-Max 80T SDD X-ray detector for energy dispersive X-ray (EDS) spectroscopy and Gatan Tridiem 866 imaging filter allowing for electron energy-loss spectroscopy (EELS) and energy-filtered imaging (EF-TEM). For imaging, the microscope is equipped with Gatan US1000 cameras (2048x2048 px) before and after the energy filter, as well as a [[LabAdviser/314/Microscopy 314-307/TEM/ETEM/OneView|Gatan OneView camera]] for fast ''in situ'' acquisition (25fps full resolution 4k x 4k, 100fps 2k x 2k, 200fps 1k x 1k, 300fps 512 x 512).<br />


The microscope is equipped with a differential pumping system which allows gases to be introduced around the sample to a pressure on the order of 10 mbar (gas specie dependent). Several gases are permanently mounted on the system: Hydrogen, helium, methane carbon monoxide, nitrogen and oxygen. Additional gases and gas mixtures can be added as needed. Please contact Cen staff if you need other gases. [[image:Titan-etem-211113.jpg|400x400px|right|thumb|Schematic of the Titan ETEM differential pumping system.]]<br />
