A versatile soft x-ray transmission system for time resolved in situ microscopy with chemical contrast

• We present the design and operation of a versatile soft X-ray   transmission system for time resolved in situ microscopy with chemical   contrast. The utility of the setup is demonstrated by results from   following a corrosion process of iron in saline environment, subjected   to a controlled humid atmosphere. The system includes a transmission   flow-cell reactor that allows for in situ microscopic probing with soft   X-rays. We employ a full field technique by using a nearly collimated   X-ray beam that produces an unmagnified projection of the transmitted   soft X-rays (below 1.1 keV) which is magnified and recorded by an   optical CCD camera. Time lapse series with chemical contrast allow us   to follow and interpret the chemical processes in detail. The   obtainable lateral resolution is a few mu m, sufficient to detect   filiform corrosion on iron.
