This Thermo Fisher Spectra 200 scanning/transmission electron microscope (S/TEM) is under installation and expected to open to users in the first quarter in 2023. It has a cold-field emission gun (C-FEG with 0.3 eV energy resolution), a Cs probe corrector for sub-0.1 nm resolution HAADF imaging; a Super X energy-dispersive spectrometer (EDS) for atomic resolution EDS mapping, Gatan energy-filter imaging and electron energy loss spectroscopy (EELS); a bi-prism; and an EMPAD for 4D-STEM.
