Free Electron Lasers open the door for novel experiments such as single shot imaging of molecules. For the success of the imaging experiments a detailed understanding of the ligth -- matter interaction in the x-ray regime is pivotal. We have performed first investigations about intense x-ray -- cluster interaction with femtosecond pulses from the Linac Coherent Light Source (LCLS) free electron laser in Stanford. We have studied the Coulomb explosion of argon clusters as a function of intensity and pulse length. The ionization dynamics in the keV photon energy regime will be compared to previous experiments in the soft x-ray regime at FLASH.
