Measuring Transport Properties in Warm Dense Matter at the OMEGA Laser Facility*

X-ray Fresnel Refractive - Diffractive Radiography (FDR), has been adapted to measure transient changes in density gradients between two species of warm dense matter (WDM). This platform combines micron-sized X-ray sources with isochorically heated cylindrical samples at large laser facilities such as OMEGA and NIF [1,2]. The high spatial coherence built into this technique enhances the refractive and diffractive features and provides a measurement of dynamic processes at the material interface [3]. We will discuss the successful imaging of thermal conductivity from recent OMEGA experiments and plans for implementation for upcoming experiments at NIF.
