One of the most fascinating applications of the European XFEL is the study of nanostructures by means of scattering experiments using ultra-short and extremely intense X-ray pulses. A challenge in these experiments is the loss of phase information needed for image reconstructions in order to make statements about the morphology of the diffracting object. The Droplet Coherent Diffracitve Imaging (DCDI) [Struct. Dyn. 2, 051102 (2015)] technique provides a fast method for retrieving phase information of nanostructures, such as clusters grown in helium droplets. In this case, the droplet serves as a reference object and as a container. This poster deals with the design and characterisation of a doping oven for embedding metals in helium droplets for an approved XFEL beamtime. Quadrupole mass analyzer and time-of-flight mass spectrometer measurements are performed for the investigation of the doping process. Furthermore, the structures of the embedded metals are deposited and afterwards investigated by transmission electron microscopy. This setup will be available at the SQS instrument at the European XFEL. In a final beamtime nanostructure formation in the droplets will be investigated.
