For information about the Postdoctoral Fellow position in coherent diffractive imaging and tomography see here. Please feel free to contact Andreas Menzel for more information. call for proposals, the cSAXS facility offers as part of the European soft-matter infrastructure (ESMI) an additional line of proposals. Frequently, such experiments can be scheduled on shorter notice. The ESMI program can offer travel support for up to two researchers.

- 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)).
