Description

Free-Electron Lasers (FELs) are capable of producing intense and ultrashort X-ray pulses, which enable femtosecond time-resolved diffractive imaging experiments. This allows to initiate chemical reactions in molecules using an optical pump pulse and probing the induced changes in the nuclear structure by X-ray scattering using a delayed FEL pulse. Here, results on the strong-field induced dynamics of C${}_{60}$ molecules probed by X-ray scattering will be presented. Furthermore, transient absorption experiments on the UV-induced dynamics of small carbon containing molecules, probed with a broadband soft X-ray pulse from a High Harmonics source, will be shown. An outlook on experiments with the new Athos AMO endstation at SwissFEL will be given.
