Title:	Electrical conductivity measurements of ion-driven plasmas
Abstract:	The high intensity heavy ion beams provided by the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung (GSI) Darmstadt are an excellent tool to produce large volumes of high energy density (HED) matter. Thermophysical and transport properties of HED matter states are of interest for fundamental as well as for applied research. During the last few years development of new diagnostic techniques allowed for a series of measurements of the electrical conductivity of heavy ion beam generated HED matter. These experiments provide us with the basis for future measurements in the frame of the HEDgeHOB collaboration. In this report we present the most recent experimental results for the electrical conductivity obtained by the four point measurement technique as well as the improved design of and preliminary results achieved by a non-contact radio frequency technique. The experiments on which we report have been performed with targets consisting of foils of Lead and Tantalum. Uranium beam pulses with durations between 100 and 1000 ns, intensities of up to 4·109 particles/bunch and an initial ion energy of 350 AMeV have been used as a driver. An energy density deposition of about 1 kJ/g has been achieved by focusing the ion beam to a few hundred micrometers FWHM focal spot size. The authors would like to acknowledge the financial support through the BMBF, INTAS and HRJRG.
