Small Angle X-ray Scattering, SAXS, is a powerful technique to characterize nanostructured details in the range of 1000 to 1 nm. Size, shape, orientation, state of aggregation and interaction between the scattering objects can be characterized by SAXS. Even more, the technique is not destructive, sense large volume areas of statistical relevance and can work with any state of the matter.
SAXS experiments can be performed with laboratory x-ray sources. However, the use of synchrotron sources, due to the high photon flux and small divergence, together with appropriate sample environment provides unique opportunities to study complex and heterogeneous systems over a broad range of simultaneous length and time scales (10-3 ≤τ ≤ 10-4 sec).
In this work, we will cover theory, experiments and data analysis (data reduction and modelling) of the SAXS technique using one of the state of the art scattering instrument, the CoSAXS beamline at the MAX IV laboratory in Lund Sweden. The theoretical part will include basic concepts of synchrotron radiation and small angle x-ray scattering. The experimental part will consist of sample preparation, the use, calibration and optimization of a suitable sample environment, and data collection at the beamline with assistance of the beamline staff.
During your stay at the lab, you will also participate on the CoSAXS beamline team activities.
A report with the lessons learnt from the experience will be produced at the end of the project. Main highlights will be presented to the beamline team in an internal seminar.
