摘要: 探索了磁场准等熵驱动飞片发射的实验技术,在FP-1装置上成功实现了多种尺寸飞片的驱动实验,并利用VISAR系统获得了飞片的速度历史曲线。在回路放电峰值为3 MA的情况下,获得飞片最高速度为797.3 m/s。初步获得了准等熵加载的原理性技术及其基本原理,促进了磁驱动准等熵加载、发射飞片实验技术,以及后续的物态方程研究的开展。Abstract: Experiments were performed to investigate the quasi-isentropic magnetically driven flyer plates with several sizes on FP-1, and their velocity histories were recorded by VISAR. When the maximum current was 3 MA, the maximum velocity of flyer plate was 797.3 m/s. Through this work, we get the principle technique for quasi-isentropic load. This will be helpful to further development of the magnetically driven quasi-isentropic load technique, launching flyer plates technique and the study of equation of state.
