Zusammenfassung

In the rush towards better resolution, transmission electron microscopes (TEM) have been made progressively stiffer; a term used in control theory to indicate that a system is very stable. Such a system is static and therefore slow to react to external stimuli. In the current operation paradigm, the overall state and the settings of the TEM are barely tracked, let alone regulated through feedback. During typical TEM measurements, the alignments are unchecked and their drift brings the microscope in a progressively less well-characterized state. In this project, concepts from control theory and...
