Coherent X-ray scattering and lensless imaging at the European XFEL Facility

J. Synchrotron Rad. (2007). 14, 453-470 [doi:10.1107/S0909049507037600]

[European XFEL] An artistic view of the experimental hall of the European XFEL and laboratory complex as viewed from the incoming photon tunnels.
Coherent X-ray diffraction imaging (CXDI) is a rapidly advancing form of lensless microscopy. The phase information of the diffraction pattern is embedded in a sufficiently sampled coherent diffraction pattern. Applying advanced computational methods based on iterative algorithms this diffraction pattern can be inverted to produce an image of a sample with diffraction-limited resolution. It is natural and highly attractive to use fully coherent X-ray beams produced by X-ray free-electron lasers (XFELs) for imaging nanoscale materials, magnetic domains and biological samples. In this article the scientific case, requirements and the possible realization of the coherent X-ray diffraction imaging experiments at the European XFEL Facility are discussed in detail.
