Investigation of High-Energy-Density Matter Generated by Intense Heavy Ion Beams at the GSI-Darmstadt Accelerator Facilities.

Objetivo

Thermophysical and transport properties of matter under extreme conditions of energy density such as equation-of-state (EOS) and electrical conductivity, are of fundamental importance to various branches of basic and applied physics. For example, astrophysics and spacecraft technology, physics of dense strongly coupled plasmas and nuclear energy industry. Traditionally, such high-energy-density (HED) states in matter have been studied using the most powerful shock wave generators like underground nuclear explosions or powerful lasers. Intense heavy beams provide a new and unique capability to research this important field. Employing intense heavy ion beams one can heat macroscopic volumes of matter fairly uniformly and explore fascinating HED areas of the phase diagram that have not yet been studied.

Due to the unique accelerator facilities, the experimental research on heavy-ion beam generated HED matter can be performed only at the GSI. The aim of this proposal is to develop experimental and heoretical approach to study properties of HED matter using intense heavy ion beams. In the framework of this proposal a number of novels diagnostic techniques and theoretical models will be developed. This includes development of fast radiation pyrometry to measure the target temperature with high temporal and spatial resolution, a number of experimental methods to measure the electrical conductivity of beam-heated target or optical diagnostics of pressure and specific volume. The above diagnostic techniques will be verified and benchmarked by performing test experiments at the existing SIS-18 facility. After the precision of the diagnostic techniques is established, different materials and interesting regions of their phase diagrams will be explored experimentally. In these experiments EOS and transport properties of dense non-ideal plasmas, metal-insulator, evaporation or plasma phase transitions as well as the critical points will be investigated. As a result of this work, the diagnostic methods essential for the future HED experiments at the SIS-100 accelerator will be made available.
