Coherent X-ray diffractive imaging beyond conventional crystallography, using isolated molecules in the gas phase, shall become feasible using upcoming x-ray free-electron lasers. We have performed benchmark experiments using LCLS at SLAC on state-selected and strongly aligned ensembles of individual gas-phase molecules in a cold supersonic molecular beam [1]. Here, we discuss data analysis and simulations for this novel approach in structure determination with the prospects of four-dimensional atomic resolution imaging.
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.)
