The new customized SAXS/WAXS instrument from XENOCS has been installed in the JCNS X-ray laboratory since the end of 2021.


As a young member of our small-angle scattering instruments using X-ray as the beam, the new instrument is equipped with a high flux metal-jet source and a moveable Eiger 2R4M SAXS detector. With an additional 4-axis motorized WAXS detector and Bonse-Hart USAXS, the scattering vector q can cover a wide area from 0.0002 to 7 Å-1. Compared to other instruments, it also comprises a large sample environment station that can be used with ambient pressure conditions. Many sample environmental accessories make it possible to perform experiments at temperatures from -150 °C to 1000 °C, under shear, tensile, etc.


The instrument is under commissioning and is expected to operate in Autumn 2022.
