Auto Tuning for HR-STEM for crystalline sample.

Micro electron diffraction, or microED, is a technique aimed at solving structures of biological macromolecules by electron diffraction. Barn-storming work by the group from Prof. Gonen showed the impressive impact and promise of this technique1. The technique borrows from X-ray crystallography in that precession techniques are used for data collection and that much of the well-established software for solving structures by X-ray crystallography can be used for microED. However, it differs in a fundamental way in that electrons are used, which, owing to the substantially larger scattering cross-section of electrons with biological matter, means much smaller crystals can be used.

An e-ABF is observable as a "live image" with real-time signal processing of ABF and BF signals and it shows enhanced contrast of light atoms.

Resolution can be improved for all accelerating voltages.

Data set for observing ferromagnetic samples. The mode has no magnetic field around samples.
