The uncorrected FEI TitanX 60-300 microscope at NCEM is equipped to do fast energy dispersive X-ray mapping (EDS), 4D-STEM, S/ TEM imaging and tomography. All TEM holders that are compatible with FEI microscopes can be used for heating, cooling and other in-situ experiments. The ability to switch between 60, 80, 120, 200, and 300kV during one TEM session gives the user flexibility to optimize experimental conditions – balancing sample damage, spatial resolution, and signal-to-noise.
Images are acquired with a Gatan UltraScan 1000 (2k x 2k) Camera for high-resolution TEM, a Gatan Orius 830 (2k x 2k) for diffraction and movies (30 frames per second), or a ADF detector for STEM. The Bruker windowless EDS detector with a solid angle of 0.7 steradians enables high count rates with minimal dead time. The ~5 mm pole gap of the FEI Super-twin objective lens is compatible with a variety of holders. Advanced experimental techniques such as 4D-STEM and EDS with tomography are being implemented on the TitanX.
Most TEM holders that are compatible with FEI microscopes are available. See the TEM Holder page for more details.
