cSAXS – X12SA: Coherent Small-Angle X-ray ScatteringAccess to cSAXS is granted through the biannual call for proposals.
We have two open postdoctoral positions in our group, Coherent diffractive imaging / Heterogeneous catalysis and SAXS/WAXS imaging.
Experiment typesExperiments performed at cSAXS include, inter alia,
- 3D coherent diffractive imaging (CDI), in particular by ptychographic means, see for example Dierolf et al., Nature 467, 436 (2010). Dedicated instrumentation, which is available to users, is described in Holler et al., Sci. Rep. 4, 3857 (2014).
- optics characterization, see for example Vila-Comamala et al. Opt Express 19, 21333 (2011)
- small-angle X-ray scattering (SAXS), e.g., Smeulders et al., Nature 478, 412 (2011), can be performed with spatial resolution as microscopy technique (Deyhle et al. Nanomed-Tanotechnol 7, 694 (2011)) and/or with time resolution in the millisecond range (Westenhoff et al., Nature Methods 7, 775 (2010)).
