Simulations of FEL-excited matter — •Nikita Medvedev¹, Beata Ziaja¹, Christoph Bostedt², Henry Chapman¹, Tim Laarmann³, Thomas Moeller⁴, Robin Santra¹, Fenglin Wang¹, and Edgar Weckert⁴ — ¹Center for Free-Electron Laser Science at DESY, Notkestr. 85, 22607 Hamburg, Germany — ²LCLS, SLAC, Stanford, USA — ³HASYLAB, DESY, Hamburg, Germany — ⁴TU Berlin, Berlin, Germany

We apply continuum approach to follow the dynamics of irradiated complex samples. First we discuss its advantages and limitations when compared to other modelling methods. We then apply this approach to describe data on irradiated clusters and laser-created plasmas that were recorded at the free-electron-laser (FEL) FLASH facility at DESY Hamburg. We show a good agreement between experimental results and our theoretical estimations. Finally we give an outlook on applying the continuum approach to describe ultrafast transitions within FEL-excited solids.
