The aberration-corrected ultra-high vacuum scanning transmission electron microscope Nion UltraSTEM 100 is at the heart of the group's experimental activities. The instrument has a constant-current operation mode for voltages between 55 and 100 kV with a probe size of ca. 1 Ångström, allowing atomic-resolution microscopy and spectroscopy. Its objective area has been modified for experiments in controlled atmospheres between 10^-10 and 10^-6 mbar, laser heating through a viewport, and an high-vacuum transfer line directly connecting it to the CANVAS system.
