Coherent x-ray scattering

We use coherent x-rays produced by 4th generation synchrotrons and free-electron lasers to study mesoscale structures and ultrafast dynamics in soft matter.

The main focus is on fundamental problems in chemistry and physics with biological relevance that often require replenishable sample delivery using liquid microjets and aerosol beams. Applications include coherent x-ray scattering of water structure and ice nucleation upon deep supercooling, coherent diffractive imaging of viruses, cells and proteins as well as serial femtosecond crystallography and x-ray photon correlation spectroscopy of proteins in crystals and aqueous solutions.
