Swedish proposals for the upgrade of PETRA III
You're welcome to engage in the development of these proposals
For the 1 December deadline, Swedish researchers are engaging in writing scientific instrument proposals (SIPs) that will be used in defining the beamlines at the future PETRA IV.
To anchor the needs of the Swedish Material Science and Engineering research community, CeXS organised an online workshop on 14 September. At that workshop, people heard and discussed the following proposals that are under development.
- Multi-scale characterization of bulk materials by a combination of WAXS/diffraction, SAXS and imaging techniques. Principle investigator: Stephen Hall, Lund University. This instrument will provide length-scale coverage from picometers (spatially averaged) up to millimetres by correlated, spatially resolved scattering and transmission-based imaging with a strong focus on following processes and structural evolutions during in-situ experiments.

- Surface diffraction for linking atomic-scale surface structures with the functions of heterogeneous and electro-catalysis, electrolysis and corrosion resistance. Principle investigator: Johan Gustafson, Lund University. This proposal will enhance the high-energy surface X-ray diffraction setup presently available at SMS. The new methodology together with the properties of PETRA IV will allow, for the first time in our application areas, operando studies i) on the time scale of ongoing chemical processes as well as ii) probing surfaces with extreme levels of spatial precision.

- Very high spatial resolution by coherent or incoherent X-ray imaging. Principle investigator: Peter Hedström/Jens Birch, KTH/Linköping University. This instrument design aims at making use of the PETRA IV X-ray properties to develop a bulk X-ray microscope with nano-scale spatial resolution. Coherent and incoherent X-ray microscopy techniques will be explored together with the high penetration power of the high-energy X-ray beam, enabling the use of complex sample environments.
You are welcome to contact the principle investigators for further discussion about capturing your ideas and future research needs these proposals - as well as to provide feedback!
