The new Small Angle X-ray Scattering Beamline for Materials Research (SAXSMAT) at PETRA III — •Sylvio Haas, André Conceicao, Xiao Sun, and Saskia Pfeffer — Deutsches Elektronen Synchrotron (DESY), Photon Science Division, Hamburg, Germany

Modern applications and basic research in catalysis, biotechnology and materials are often concerned with hybrid and synergetic systems. In other words, systems that brings enhanced properties and performances due to their internal complexity. The challenge is now in understanding the interactions leading to their assembly and operation. Due to their inherent chemical and structural complexities, a combination of several techniques simultaneously and/or an advanced method is mandatory to determine structural and chemical information of materials.

Small-Angle X-ray scattering (SAXS) is a well-established method to investigate nanostructured materials. Information about particle size distribution, particle shapes, and inter-particle interaction potentials can be determined. Currently, DESY is commissioning a new beamline (P62; SAXSMAT) dedicated to this technique that will be open for user operation in the near future. The X-ray energy can be tuned between 3.5 keV to 35.0 keV. In this presentation the SAXSMAT beamline will be presented including the key features of the beamline:

I.) anomalous SAXS/WAXS: adding element sensitivity II.) SAXS/WAXS computed tomography: adding 3D spatial resolution III.) In situ and In operando SAXS/WAXS: adding time resolution
