Toward atomic resolution X-ray imaging of isolated molecules — •Stephan Stern1,2, Jochen Küpper1,2, Henry Chapman1,2, and Daniel Rolles3 — 1Center for Free-Electron Laser Science (CFEL), DESY, Hamburg — 2University of Hamburg — 3Max Planck Advanced Study Group at CFEL, Hamburg
X-ray diffractive imaging is an indispensable tool in science, i. e., for examination of the structure of matter and complex molecules. X-ray Free-Electron Lasers allow for ultrafast time-resolved diffractive imaging of, for example, nanocrystals or individual viruses. Here, we present first results on the diffractive imaging of controlled – state-, size-, and isomer-selected and strongly aligned – ensembles of individual gas-phase molecules. We have performed the first corresponding experiments using LCLS at SLAC on diiodobenzonitrile and will present details on the experimental realization, the theoretical background, and a detailed analysis of the obtained experimental data.
This work was carried out within a collaboration, for which J. Küpper, H. Chapman and D. Rolles are spokespersons. The collaboration consists of CFEL (DESY, MPG, University Hamburg), Fritz-Haber-Institute Berlin, MPI Nuclear Physics Heidelberg, MPG Seminconductor Lab, PNSensor GmbH, Aarhus University, FOM AMOLF Amsterdam, Lund University, MPI Medical Research Heidelberg, TU Berlin, Max Born Institute Berlin, and SLAC Menlo Park USA. The experiments were carried out using CAMP (designed and built by the MPG-ASG at CFEL) at the LCLS (operated by Stanford University on behalf of the US DOE.)
