Instrumentation

The probe-corrected ARM200F is a state-of-the-art (S)TEM with exceptional stability and the capability to produce a very small probe. The microscope is also equipped with advanced EELS and EDX systems for chemical analysis. High energy resolution at high spatial resolution is thus obtainable. The system is set up for operation at voltages of 30 kV, 60 kV, 80 kV and 200 kV. Sample holders for in situ heating and cooling as well as for electron tomography are available.

The CM200 is a widely-used microscope, excellent for conventional TEM work. It has a LaB₆ source, operated with a 200kV accelerating voltage. This TEM is ideal for bright field and dark field imaging, and for dislocation and defect analysis using diffraction contrast imaging, including the weak-beam dark field technique. The available range for tilting is large and the microscope can accommodate a cooling holder.
