Information technology relies on reliable storage and fast switching of material states. These states can be governed either by magnetic or electrical degrees of freedom, which offers a wide variety of design concepts. Common to all storage concepts is that manipulation of the information state takes place on a characteristic time and length scale, which is in the picosecond respective nanometer range. All requirements are combined in the method of time-resolved photoemission microscopy (TR-PEEM). Recently, we installed a state-of-the-art PEEM with energy-filtering system and aberration corrector (FE LEEM-P90 AC by SPECS) at the FZ-Jülich Beamline UE56/1-SGM @ BESSY. In this poster we present the extension of the microscope setup for synchrotron pump-probe measurements. We will present details about the technical performance of the setup as well as first results on magnetization dynamics in ferromagnetic nanoelements.
