The Linac Coherent Light Source (LCLS) is a new, world wide unique X-ray free electron laser (FEL), which produces ultrashort pulses up to 2keV with unprecedented brightness. One of the most promintent applications of this powerful tool is imaging of unrevealed ultrafast atomic and molecular processes. We report on the first imaging experiment at the LCLS. It was performed on rare gas clusters, which can be applied as simple model systems for interaction between X-ray laser and matter. We used single-photon counting pnCCD detectors for observing scattering and fluorescence. As clusters are destroyed by the ultra intense pulse, the observation of ionisation products is crutial for the understanding of interaction dynamics. They were detected simultaneously with advanced ion /electron spectrometers (VMI). This experiment was performed in the CFEL-ASG Multi-Purpose (CAMP) chamber which contains a unique combination of analysis instruments for exploring the interaction of intense (soft) x-ray radiation and matter.
