The FEI (now ThermoFisher) Titan G3 50-300 PICO is a unique fourth generation transmission electron microscope which has been specifically designed for the investigation of a wide range of solid state phenomena taking place on the atomic scale and thus necessitating true atomic resolution analysis capabilities. For these purposes, the FEI (now ThermoFisher) Titan G3 50-300 PICO is equipped with a Schottky type high-brightness electron gun (FEI X-FEG), a monochromator unit, and a Cs probe corrector (CEOS DCOR), a Cs-Cc achro-aplanat image corrector (CEOS CCOR+), a double biprism, a post-column energy filter system (Gatan GIF Continuum K3 1069 system with a direct detection K3 camera and a second scintillator based 1069.EXUP camera) as well as a 16 megapixel CCD system (Gatan OneView Camera). Characterised by a TEM and STEM resolution well below 50 pm at 200 kV, the instrument is one of the few chromatically-corrected high resolution transmission electron microscopes in the world. Typical examples of use and technical specifications for the instrument are given below.

Sample Environment

The FEI (now ThermoFisher) Titan G3 50-300 PICO allows samples to be investigated under room temperature at a vacuum level of about 10–8 mbar. Besides this standard setup, the sample environment can be adapted to various conditions, such as cooling or the application of external electric or magnetic fields to samples, making use of a wide portfolio of in situ TEM holders available through the ER-C user services. Sample heating is not supported.
Typical Applications and Limitations of Use

The configuration of the FEI (now ThermoFisher) Titan G3 50-300 PICO allows a variety of advanced transmission electron microscopy techniques to be applied to wide bunch of solid state materials. These techniques include electron energy loss spectroscopy (EELS), energy filtered transmission electron microscopy (EFTEM) and 4D scanning transmission electron microscopy (4D-STEM), high resolution transmission electron microscopy (HRTEM), high resolution scanning transmission electron microscopy (HRSTEM) with annular detectors for bright-field, annular dark-field, and high-angle annular dark field imaging, off axis electron holography (OAEH), electron tomography (ET), and combinations of the previous techniques. The FEI (now ThermoFisher) Titan G3 50-300 PICO is not intended for the investigation of aqueous, contaminated, ferromagnetic or organic samples without further discussions with both of the instruments officers and the ER-C general management.
