Target design for studies of radiative properties in warm dense matter at GSI and FAIR - The WDM collaboration

Intense beams of energetic heavy ions from SIS-18 at GSI can heat extended volumes of condensed matter to a temperature of several eV. The matter at about solid density and a temperature near or above the Fermi temperature is referred to as Warm Dense Matter (WDM). The knowledge of radiative properties and the equation of state of WDM is particularly limited because standard perturbative theoretical approaches are not applicable in this regime. The kilojoule PHELIX laser at GSI can be used to produce X-rays of several keV energy for scattering diagnostics of ion beam heated matter. In this paper special target configurations for compression and isochoric heating of matter with heavy ions are presented. The possibilities of X-ray scattering diagnostics of such targets are discussed. The target parameters achievable with the new FAIR facility are calculated.
