UE49_PGM SMART
UE49 SMART
The high flux density beamline is specially designed for the high resolution, aberration corrected spectromicroscope SMART. Located in a low-beta section with a round undulator source the PGM beamline illuminates the specimen surface in the SMART electron microscope with an ideal round beam with high flux density. The wide energy range of 100 to 1800 eV gives access to nearly all relevant XPS peaks and NEXAFS adsorption edges, used for chemical contrast in the photoemission electron microscope to study the local chemical composition on the surface in nanometer range.

The wide energy range of 100 to 1800 eV gives access to nearly all relevant XPS peaks and NEXAFS adsorption edges, used for chemical contrast in the photoemission electron microscope to study the local chemical composition on the surface in nanometer range. The variable choice of horizontal, vertical and (left/right) circular polarized light enables the investigation of e.g. molecular orientation in organic films or the magnetization in magnetic domains.
