The Cs- and Cc/Cs-Correctors were first developed as prototype instruments at the European Molecular Biology Laboratory (EMBL) in Heidelberg by Haider, Zach and co-workers. The research on the Cs-Corrector was done under a grant from the Volkswagenstiftung Germany.
The first Cs-corrected transmission electron microscope (TEM) was then transferred to the Forschungszentrum Jülich, where first applications of corrected microscopy have been carried out.
We have developed a purely electrostatic Cc/Cs-corrector. Correction of chromatic and spherical aberration in an ion optical column could be demonstrated resulting in a significant improvement of resolution.
Within the TEAM project CEOS has developed a magnetic/electrostatic Cc/Cs- corrector for a transmission electron microscope. It has been placed at the disposal of the scientific community at the user facility of NCEM in october 2009. There scientists are allowed to use it for their own purposes.
The application of corrected electron microscopes makes it now possible to do without the restrictions which were up to now thought to be necessary for achieving high resolution. This opens up new prospects for the microscope users.
