Abstract: We present first time-resolved measurements obtained with a new transmission microscope at the soft X-ray beamline P04 of the highbrilliance synchrotron radiation source PETRA III.A nanostructured magnetic permalloy (Ni80 Fe20 ) sample can be excited either by making use of a mobile synchronized femtosecond lasersystem or by a 250 ps electric current pulse via a coplanar waveguide. The full-field soft X-ray microscope successively probes the time evolu-tion of the magnetization in the sample via XMCD spectromicroscopy in a pump-probe scheme. Static and transient magnetic fields are avail-able in the sample plane by permanent magnets and coils to reset the system and to provide external offset fields.The microscope generates a flat-top illumination field of 20 μm diameter by using a grating condenser and the sample plane is directly imaged by a micro zone plate with < 65 nm resolution onto a 2D gateable X-ray detector to select one particular bunch in the storage ring that probes the dynamic information.
