To put these optics into use for imaging applications, we have commissioned a new dedicated sample tower as a high-resolution module for the GINIX instrument, stationed at the P10 beamline at PETRA III. Here we summarise the motorisation and show first imaging benchmark results obtained with a \"traditional\" Fresnel Zone Plate. The first 2D continuous STXM scan using the new EigerX 4M detector at full 750 Hz speed is shown: a field of view of roughly about 1 μm squared has been recorded with 255 × 255 images within 96 seconds."],["dc.identifier.doi","10.1088/1742-6596/849/1/012049"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62920"],["dc.language.iso","en"],["dc.relation","SFB 755: Nanoscale Photonic Imaging"],["dc.relation.eissn","1742-6596"],["dc.relation.issn","1742-6588"],["dc.relation.issn","1742-6596"],["dc.relation.orgunit","Institut für Röntgenphysik"],["dc.rights.uri","http://creativecommons.org/licenses/by/3.0/"],["dc.subject.gro","x-ray optics"],["dc.subject.gro","x-ray imaging"],["dc.title","Preparing for hard x-ray microscopy with Multilayer Zone Plates"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

The real-space resolution of typical imaging modalities like fluorescence mapping, scanning SAXS and WAXS depend on the available beam size. Although routine in the 5–25keV regime [1-4], spot sizes below 50nm are very challenging at x-ray energies above 50 keV: Compound refractive lenses lack in refractive power, the multilayer thickness of coated mirrors is bounded by interfacial diffusion, and lithographic Fresnel Zone Plates loose their efficiency in the two-digit keV regime. Multilayer Laue Lenses and Multilayer Zone Plates (MZP) are promising candidates for high-keV focusing to small spot sizes; compared to Fresnel Zone Plates, the aspect ratio comparing outermost layer width (~focal spot size) to optical thickness (efficiency) is virtually unlimited by the fabrication. Using Pulsed Laser Deposition on a rotating wire (several millimetre long), we have fabricated an MZP with 10nm outermost zone widths and optical thickness of 30 μm(optimum phase shift at 60 keV), yielding an unprecedented ultra-high aspect ratio of 1:3000 (outermost zone width compared to optical thickness). We present experimental results obtained at ESRF’s high energy beamline ID31, where for the first time scanning experiments with real-space resolutions below 50nm even at x-ray energies ranging from 60 keV to above 100 keV have been achieved."],["dc.identifier.doi","10.1117/12.2271139"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62921"],["dc.language.iso","en"],["dc.relation","SFB 755: Nanoscale Photonic Imaging"],["dc.relation.conference","SPIE Optical Engineering + Applications, 2017,"],["dc.relation.eventend","2017"],["dc.relation.eventlocation","San Diego, California, United States"],["dc.relation.eventstart","2017"],["dc.relation.isbn","978-1-5106-1229-7"],["dc.relation.isbn","978-1-5106-1230-3"],["dc.relation.ispartof","Proc.
