Title:	Generation of relativistic return flows in ultra-intense laser-plasma interaction
Abstract:	The interaction of ultra-intense laser radiation with matter is capable of increasing the critical plasma density, thus generating very energetic electrons and large electric currents. Since electric currents in a plasma must be compensated by appropriate return currents, very large electric currents can lead to the generation relativistic return flows. The presentation discusses the generation and properties of relativistic return flows. The findings may bear relevance for the concept of Fast Ignition in Inertial Confinement Fusion.
