The FEI Themis Z S/TEM is a state-of-the-art Cs probe-corrected field emission gun scanning/transmission electron microscope capable of providing micro- to atomic-scale structural, morphological, magnetic, and chemical information.

Instrument Specifications:

  • Configured for 60, 200, or 300 kV operation
  • X-FEG high brightness Schottky field emission gun with monochromator
  • Cs probe-corrected (to 5th order) S-twin objective lens with 5.4 mm pole piece gap
  • FEI single-tilt, double-tilt (SoftLoc), and Fischione Instruments tomography holders available; piezo-enhanced CompuStage with 20 pm minimum step size
  • Bottom-mounted FEI Ceta 16 megapixel CMOS camera with speed enhancement
  • Fischione Instruments Model 3000 HAADF-STEM detector; FEI BF, DF2 (segmented), and DF4 (segmented) STEM detectors for DPC imaging
  • <60, <80, and <100 pm STEM resolution at 300, 200, and 60 kV, respectively
  • High-resolution (lattice) imaging with <0.1 nm information limit
  • Dedicated Lorentz lens for Lorentz TEM and STEM imaging of magnetic specimens; ~1 nm Lorentz STEM resolution enabled by Cs probe-correction
  • Super-X windowless SDD energy dispersive spectroscopy system with 0.7 sr solid angle of collection; fully automated EDS tomography data acquisition
  • Electron Microscope Pixelated Array Detector (EMPAD); 128x128 direct electron detector with 150 um pixel size; single electron sensitivity with 30 bit dynamic range; diffraction pattern recorded at every point in a map (4D-STEM)
  • Gatan Continuum ER post-column energy filter; DualEELS; BF/DF STEM detectors; 2.5 and 5.0 mm EELS entrance apertures; 9 mm imaging aperture, energy selecting slit
