| 摘 要： | 准等熵压缩实验技术已用来研究材料在高压下的状态方程。基于聚龙一号装置平台，实现对样品的准等熵压缩和超高速飞片发射，进行了一系列实验来加深对负载构型的理解。通过对负载结构的设计，研究了构设电极尺寸与电极间隙对磁应力的大小与分布的影响。基于模拟和实验结果，带状线负载结构可以很好地提高磁压和提升装置的运行水平，其电极表面磁压分布也具有良好的均匀性和平面性。目前为止，已经可以用带状线负载在聚龙一号装置上获得峰值压力高达约100 GPa的准等熵压缩，并获得速度超过10 km/s的超高速飞片。

| Abstract: | Isentropic compression experiments have been developed for the study of the equation of state for materials at extreme pressures. We use the PTS facility to achieve a quasi-isentropic compression and hyper-velocity flyer launch. A series of experiments for the understanding of the load configuration design, such as the load structure, the electrode gap and plate size, are presented, analyzed, and compared. The electromagnetic simulation has been used to analyze the magnetic fields amplitude and uniformity on the inner surfaces of the load configurations. Some load configurations are designed for the study of the uniformity and consistency of the magnetic pressures on the electrode surfaces by a ramped compression wave. Based on the simulation and experiments, a stripline load configuration is chosen to enhance the magnetic pressures and improve the PTSs performance for isentropic compression experiments. Until now, an isentropic pressure of about 100 GPa and more than 10 km/s flyer launch demonstrated on the PTS facility have been obtained using the stripline loads. |
