MAXYMUS (MAgnetic X-raY Micro- and UHV Spectroscope), a next generation cutting-edge UHV scanning magnetic X-ray micro-spectroscope has been developed for high-resolution magnetic and nonmagnetic contrast imaging, local XMCD/XAS spectroscopy (less than 20nm lateral spectro-microscopy resolution). It has been installed in an especially build noise-reducing and temperature stabilizing cabin at the newly constructed PGM undulator beamline (UE 46-2) at BESSY II, Berlin which supplies soft X-rays of elliptical or rotatable linear polarization. First measurements already showed very promising results concerning reduced noise and high-resolution, due to its exceptional high scanning stability together with the unique ability of zone-plate scanning. The instrument is equipped with worldwide unique features. New insight into dynamic behavior of magnetic systems has been gained by applying pump-and-probe measurements with time resolution of less than 50 ps. Due to UHV conditions, TEY-measurements have been performed successfully. Thus, opaque targets can also be studied. First results concerning Fresnel Zone Plate development based on Atomic Layer Deposition will be presented. The microscope will be available for external users in the second half of 2010.
