【 摘 要 】

With Pulsed Laser Deposition, Multilayer Zone Plates can be fabricated to focus hard x-ray beams into 2D spots smaller than 10 nm. 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.
