摘要: 为研究等离子体喷射驱动磁惯性融合(PJMIF)中超音速等离子体射流的形态特征,本研究采用十通道时间分辨正交外差干涉仪进行观测。通过MATLAB对射流形态与密度分布进行仿真模拟以指导实验设计。采用高斯拟合、插值计算及阿贝尔逆变换等处理方法对相位数据进行分析,成功重建了射流密度分布。实验测得射流在1016~1017cm3密度范围内呈现密度集中、边界清晰、对称性良好的特征,为PJMIF研究提供了关键诊断依据。
Abstract: To study the morphology of hypersonic plasma jets in Plasma Jet-driven Magneto-Inertial Fusion, (PJMIF), a 10-channel time-resolved orthogonal heterodyne interferometer was employed. MATLAB simulations of jet morphology and density distribution guided the experimental design. Phase data were processed through Gaussian fitting, interpolation, and Abel inversion to reconstruct the density profile. The jets exhibited concentrated density, clear boundaries, and good symmetry within the range of 1016~1017cm3, providing essential diagnostic support for PJMIF research.
