The Thermo Scientific Talos F200i (S)TEM is a 20-200 kV field emission (scanning) transmission electron microscope uniquely designed for performance and productivity across a wide range of Materials Science samples and applications. The one here at Dartmouth is fitted with the ultra-high-brightness Cold Field Emission Gun (X-CFEG) and the Dual X Energy Dispersive X-ray Spectroscopy (EDS) detectors (to enable chemical analysis).

THERMO SCIENTIFIC HELIOS 5CX DUAL BEAM SEM/FIB (SCANNING ELECTRON MICROSCOPE / FOCUSED ION BEAM)
The Thermo Scientific™ Helios™ 5 CX DualBeam combines the innovative Elstar™ Electron Column for ultra-high-resolution imaging and the highest materials contrast (the resolution can reach 0.6 nm at 30 kV STEM and 15 kV and 0.9 nm at 1 kV) with the superior Tomahawk™ Focused Ion Beam (FIB) Column for the fastest, easiest and most precise high-quality sample preparation. This instrument incorporates a suite of state-of-the-art technologies that enables simple and consistent imaging and sample preparation. The microscope is equipped with the QuickLoader™ Vacuum Technology: Loadlock for fast sample exchange without breaking system vacuum and the CryoMAT™ Kit for cryo applications allowing for easier and more practical operation than a generic full cryo transfer system. The temperature is microprocessor controlled and the stability is better than +/- 1 °C with an operating range of +50 °C to -190 °C.

The microscope has a fast beam blanker and can be controlled by a Nanometer Pattern Generation System (NPGS), which is an electron-beam lithography system. More information at: https://www.jcnabity.com/
It is equipped with two X-Ray detectors (the Oxford Instruments UltimMax 100 and the Ultim Extreme 100) and an EBSP camera (Oxford Instruments Symmetry).
Of particular interest for sample preparation:
Leica ACE600 High Resolution Coater (currently set for Au/Pd and Carbon).
