Title:	Thomson scattering in Warm Dense Matter
Abstract:	Thomson scattering provides a unique tool for plasma diagnostics. The scattering spectrum gives direct access to plasma properties like density, temperature and composition. The advent of intense, coherent light sources in the VUV and soft X-Ray regime made it possible to apply Thomson scattering to strongly correlated plasmas near solid density, inaccessible to optical probes. In such systems, collisions among constituents are of primary importance for the prediction and interpretation of the scattering signal. We present a systematic approach to the dynamical structure factor using the Born-Mermin Ansatz to include collisions via the dynamical collision frequency. Results are compared to recent experimental data, carried out on solid density targets. Results from a first scattering experiment on solid density hydrogen at the free electron laser facility FLASH at Hamburg will also be presented.
