炸药柱面内爆磁通量压缩实验技术具有加载压力高、加载过程温升低及样品体积大等特点,在材料高压物性、新材料高压合成及超强磁场下的凝聚态物理等多个领域都具有广阔的应用前景。叙述了超高速摄影技术在柱面内爆磁能量压缩实验中的研究应用,用超高速分幅摄影和扫描摄影技术首次拍摄到柱面内爆强磁场压缩过程具有高时空分辨的一维和二维图像,成功观察到柱面套筒内爆整个压缩和反弹过程以及压缩过程中的界面不稳定性现象,获得了该过程的压缩直径随时间连续变化曲线,由此计算出柱面套筒内爆强磁场压缩速度。该实验数据对于炸药柱面内爆磁通量压缩实验技术研究具有重要的指导意义。
Explosive cylindrical implosion magnetic flux compression experimental technology with high loading pressure, low temperature during the loading process and sample volume characteristics, in the material high pressure properties, high pressure synthesis of new materials and the field of condensed matter physics and other fields have Broad application prospects. The research and application of ultrahigh-speed photographic technology in the experiment of compressing the energy of the in-cylinder demagnetization are described. The first-shot high-speed submarine burst magnetic field compression process with ultra-high speed framing and scanning photography has high spatial and temporal resolution of one-dimensional and two-dimensional Image, we successfully observe the whole process of compression and bounce of cylindrical sleeve implosion and the instability of interface during compression. The curve of compression diameter of this process is continuously changed with time, and the cylinder sleeve implosion Strong magnetic field compression speed. The experimental data for the explosive cylindrical implosion magnetic flux compression experimental study has an important guiding significance.
