Short wavelength free-electron lasers (FELs) can be used to image nanostructures via x-ray scattering. Time-resolved studies of non-reproducible structures often lack of information on the initial state of the structure. A novel setup named x-ray movie camera overcomes this limitation by taking two separate time-delayed images of the same gas-phase particle by two beams from different directions. To optimize and overlap the micron foci, which are created by two opposed ellipsoidal multilayer mirrors, precise alignment is required. Raytracing the setup allows to simulate the experimental alignment and reveals the quality and shape of desired focus. By taking the adjustment operations and their effect into account the experiment’s and the simulation’s data can be compared. The results from raytracing are presented.
