Dynamics of gas clusters exposed to VUV-FEL radiation: time-resolved scattering — •Ekaterina Eremina, Christoph Bostedt, Matthias Hoener, Heiko Thomas, and Thomas Möller — TU Berlin, Hardenbergstrass 36, 10623 Berlin

We propose a two colour pump-probe based experimental technique for studying the fragmentation and explosion dynamics of rare gas clusters exposed to vacuum-ultraviolet radiation by the DESY Free-Electron-Laser. Two separated 50-fs FEL pulses of the first and third harmonics are used as the pump and probe correspondingly. The fragmentation processes induced by the first-harmonic pulse at a wavelength around 30 nm can be studied with time-resolved scattering of the third-harmonic at 10 nm.
