1. Resource Description

   The Tecnai F20 microscope is a field emission 200kV S/TEM with an X-TWIN objective lens and high brightness field emission electron gun (FEG) optimized for analytical work. This objective lens allows a 40 degree tilt with a standard low-background double tilt holder and, with the tomography holder, allows +/-70 degrees of tilt. The objective lens design allows for efficient collection of X-rays for elemental analysis down to the sub-nanometer level. With a single 30mm2 detector, the EDX acquisition solid angle for collection is ~0.4sr, rivaling more expensive systems. The system has a Gatan Tridiem imaging filter for both energy-filtered imaging and EELS spectroscopy. The various techniques are integrated into the instrument software for ease of operation. The software packages include EDX, EELS, Low-Dose, and Tomography. The Tecnai is equipped with 3 CCD cameras. There is an Orius 2k camera in the upper port giving a wide field of view, an UltraScan 2k camera in the lower position for higher magnifications, and an UltraScan 2k camera located after the energy-filter. TEM resolution is 2.4Å with STEM resolution better than 2Å.
