FEI Image Corrected Titan3™ G2 60-300 S/TEM


The image-corrected Titan3™ G2 60-300 S/TEM provides superior performance, stability, and flexibility when utilizing the Cs image-corrector and electron monochromator technology for atomic resolution imaging and spectroscopy. The flexibility of operating the Titan3™ G2 60-300 in the range of 60 to 300 kV allows for optimization of voltage to the requirements of the material examined, ranging from ultra-light carbon compounds to ultra-dense, inorganic materials. Additionally, with the relatively wide pole piece gap of the S-TWIN lens, the Titan3™ G2 60-300 is designed for dynamic experiments, with space around the sample area.  The microscope is optimized for a 130pm probe resolution and 70 pm information limit to facilitate atomic resolution imaging with local spectroscopic and x-ray data collection to compliment the capabilities of its sister CEMAS instrument, the probe-corrected Titan3™ 80-300 S/TEM.

The Titan3™ 60-300 is equipped with a high coherence, high brightness, field emission electron gun (X-FEG), a Cs- image corrector and an electron gun monochromator to provide useable probe current with an energy resolution of 0.15 eV.  The Titan3™ G2 60-300 contains a high-speed, high-throughput, quad-silicon drift detector (Super-X/ChemiSTEM) optimized for rapid x-ray collection and when combined with STEM enables EDS spectral mapping down to the atomic scale. This system is also equipped with Gatan Digiscan™ to produce high-speed spectral maps from electron energy loss spectroscopy (EELS) data. A dual-EELS spectrometer permits the user to collect low-loss and core-loss EELS simultaneously to produce, rapidly and routinely, atomic resolution EELS spectrum images. The combinations of these spectral collection tools, energy resolution and variable voltage make the image corrected Titan3™ G2 60-300 a powerful characterization tool in the modern materials world.

The system is housed in an acoustic, thermal, and electro-magnetically isolated, high-stability support box that reduces negative environmental conditions permitting optimal aberration corrected S/TEM characterization to be realized. The instrument is also available for remote viewing access and remote user control providing benefits and access to users both locally and around the state of Ohio through OARnet.
