本文借助复杂的二维流体力学模拟，提出了一种适合于Gesellschaft Fur Schwerion enforschung(GSI)Darmstadt进行的重离子束流-物质相互作用实验的合理设计和优化参数，该实验将于2001年底完成，届时现有加速器设施将完成升级。我们的模拟表明，这种升级的重离子束能够在固体靶中产生强烈的冲击波，将靶材料压缩到超固态密度，并产生多毫巴的压力。这将在GSI开启在这种极端条件下研究物质状态方程性质的可能性。数值模拟能够以合理的精度预测实验结果，有助于实验诊断工具的设计。
In this paper is presented, with the help of sophisticated two-dimensional hydrodynamic simulations, a suitable design with optimized parameters for a heavy-ion beam-matter interaction experiment that will be carried out at the Gesellschaft fur Schwerionenforschung (GSI) Darmstadt by the end of the year 2001 when the upgrade of the existing accelerator facility will be completed. Our simulations show that this upgraded heavy-ion beam is capable of generating strong shocks in solid targets that compress the target material to supersolid densities and generate multi-mbar pressures. This will open up, at the GSI, the possibility of investigation of the equation-of-state properties of matter under such extreme conditions. Numerical simulations can predict the experimental results with reasonable accuracy, which is helpful in designing the diagnostic tools for the experiment.
