Free electron lasers provide a high photon flux combined with ultrashort pulse durations.
A tightly foucussed radiation beam enables to study atoms, molecules, clusters and particles with nonlinear effects, particularly light scattering. A focus smaller than 8 x 9 µ m2 has been reached by a newly set-up Kirkpartrick-Baez optics at the BL1 of FLASH.
In combination with the permanently installed CAMP chamber [1], a multi-purpose instrument for electron and ion spectroscopy, pump-probe, and imaging experiments, it founds the base for user-experiments at high light intensities in a versatile and well-proven experimental chamber. In a first experiment very high charge states of ions from a rare gas target could be generated.
