Heavy Ion-Beam Driven Isentropic Compression Experiments

Abstract

A new design for heavy-ion beam driven isentropic compression experiments is suggested and analysed. The proposed setup utilises long stopping ranges and the variable focal spot geometry of the high-energy uranium beams delivered at the GSI Helmholtzzentrum für Schwerionenforschung and Facility for Antiproton and Ion Research accelerator facilities in Darmstadt, Germany, to produce a planar ramp loading of various samples. In such experiments, the predicted high pressure amplitudes (\unit[$<10$]{Mbar}) and the predicted short timescales of compression (\unit[$<10$]{ns}) will allow testing the time dependent material deformation phenomena at unprecedented extreme conditions.
