[en] This paper presents a setup for the fast detection of soft x-rays using a high speed camera as multimodal detector for application in the AnImaX scanning transmission x-ray microscope (STXM). AnImaX is a flexible endstation for combining scanning and full field microscopy for the XUV beamline P04 at PETRA III. While using the scanning mode there is the additional option to gather fluorescence spectra for each scanned pixel. Because of the brilliance of the P04 beamline, fast image acquisition is possible and in consequence demands a fast and efficient data management.
