Soft X-ray Spectromicroscopy at the Swiss Light Source — •George Tzvetkov^1,2, Jörg Raabe², Rainer Fink¹, and Christoph Quitmann² — ¹Physikalische Chemie II, Friedrich-Alexander Universität Erlangen-Nürnberg, D-91058 Erlangen, Germany — ²Paul Scherrer Institut, 5232 Villigen, Switzerland

A new X-ray scanning transmission microscope (STXM) located at the Paul Sherrer Institut, Villigen, is now available. The microscope is attached to the PolLux beamline at the Swiss Light Source synchrotron laboratory.The central theme of the STXM is the ability to obtain morphological and chemically-specific information on a full range of materials (inorganic/organic) under real conditions thus providing a unique facility. The operating energy range (from 200 eV to 1 keV) encompasses a significant number of important K- and L-absorption edges, and relatively thick samples can be studied with absorption contrast technique (NEXAFS spectroscopy). The range of potential applications is truly interdisciplinary, including materials science, biological and bio-medical science, and environmental science (e.g., polymers, nanomaterials, magnetic materials, biological materials, aerosols, minerals).

Here, several examples of different systems under study are presented. The overview addresses topics ranging from fundamental environmental chemistry to phase-change microcapsules.
