14th International Conference on Synchrotron Radiation Instrumentation, (SRI 2021), Online, 28 Mar 2022 - 1 Apr 2022; Journal of physics / Conference Series 2380(1), 012109 (2022). doi:10.1088/1742-6596/2380/1/012109, Two recently developed experimental devices for investigating soft matterdeformation are presented. Both devices exploit the capabilities of a modern synchrotronbeamline to enable advanced and highly precise materials-science experiments in which X-rayscattering is registered. The devices can be operated both in monotonic as well as cyclic modeand are implemented into a beamline at DESY, Hamburg (Germany). Hence, relevantexperimental parameters, such as displacement, force and temperature, are recordedsynchronously with the individual X-ray scattering patterns. In addition, spatial variation ofmaterials deformation can be monitored and recorded with optical microscopy. This uniquesample environment enables in situ X-ray experiments in transmission, i.e. small- or wide-angleX-ray scattering (SAXS or WAXS), and in grazing-incidence geometry, i.e. grazing-incidence(GI-) SAXS or WAXS. One device with stepper motors is designed for studies of slow, (quasi-)static deformation and the other one with pneumatic actuators can be used for fast, impactdeformation. Both devices are available to external beamline users, too., Published by IOP Publ., Bristol
