Thermo Scientific Spectra φ FEGTEM
Instrument Manager: A/Prof. Matthew Weyland
Instrument Location: G23
Description: The Spectra - φ (Phi) is a high brightness, monochromated field emission gun (X-FEG) transmission electron microscope. It is fitted with fifth order spherical aberration corrector in the probe forming lenses, and a third order spherical aberration corrector in the image forming system. It has STEM resolution of half an angstrom (0.05 nm), and an energy resolution of less than 20 milli electron volts. Its unique column is optimised for optical flexibility, with alignment free voltage switches from 30 to 300kV, and high speed, megapixel, direct electron imaging.
Technical Configuration: Monochromated FEG-TEM/STEM; X-FEG source with double Wein field monochromator, Operates at 30kV, 60kV, 80kV, 200kV and 300kV; Full range constant power SuperTWIN pole piece, with rapid (<30min) HT switch to stable; New aperture strip design with 15-17 apertures per position.
