Scattering pattern of a single, large, non-spherical xenon twin-cluster obtained with a single FEL pulse of 90 eV photon energy (60 µJ, 100 fs pulses). A maximum transferred momentum of 0.3 nm−1 could be obtained within this experiment. The combination of different pnCCD modules with 50 nm and 150 nm Al coating used in this experiment allowed for an even larger dynamic range (see color scale on the right side). The image on the upper module (50 nm Al coating) shows both saturation in the center of the detector as well as single photon signal, e.g. in the area indicated by the red box. On the lower detector module (150 nm Al coating) the unsaturated scattering signal in the zero-order maximum could be retrieved simultaneously. The inset on the lower left side shows a simulated image (two-dimensional FFT of the given outline). The non-spherical geometry of the nano-cluster is a signature of the cluster growth by coagulation (Rupp et al., 2012BB51), a gas-phase process that can be studied only via single-particle diffractive imaging.
