PETRA III, located on the site of DESY (Hamburg) is the world's most brilliant synchrotron radiation source. The nanofocus endstation of its MiNaXS-Beamline (Micro- and Nanofocus X-ray Scattering) is currently on the verge of entering into user-dedicated mode.
MiNaXS was designed to provide a high flux, low divergence monochromatic x-ray beam (8-23 keV) and it's nanofocus endstation is targetting to deliver a nanofocused beam with a focal spot size in the order of 100nm * 100nm and a high coherence option dedicated for diffraction experiments at both biological and synthetic materials. Experiments can be performed in both wide-angle and small-angle x-ray scattering geometry (WAXS and SAXS) and this combined with the targetted spatial resolution being so far unique.
The very first commissioning experiments were successfully performed in November and December 2010 at the nanofocus endstation, rendering the MiNaXS beamline operational at both of it's endstations. This contribution presents the current status of the nanofocus endstation, the results of the commissioning experiments as well as the planned future extensions.
