Talk given by PD Dr. Eberhard Goering MPI für Intelligente Systeme, Stuttgart Abstract: The MPI-IS operates a new and versatile state of the art soft X-ray scanning microscope (SXM), called MAXYMUS, which is open for user application and located at the undulator beamline UE46 at the HZB/BESSY in Berlin. It provides many unique possibilities, as its UHV capability, providing simultaneous surface sensitive investigations, utilizing total electron yield detection (TEY), simultaneously performed with high performance volume sensitive transmission experiments. This allows spatial resolutions down 10nm. Recent examples will be presented, showing all facets of XMCD based magnetic and nonmagnetic microscopy and micro spectroscopy, where strong, variable, and rotatable magnetic fields, a temperature range from about 80-400 K, rotatable sample holders are prerequisites. In additional, special scanning modes like zone plate scanning and ultra-fast measuring modes are available, allowing time dependent measurements with synchrotron limited time resolution (below 40ps) and excitation frequencies up to 16 GHz. With a new high performance CCD system, ptychography could be performed (1000 frames/s and single photon counting), allowing fast scans and spatial resolutions limited by the soft x-ray wavelength. A detailed introduction to x-ray microscopy and especially SXMs will be provided, including many magnetic and nonmagnetic examples performed at MAXYMUS.
