| 摘 要： | 射流是激光惯性约束聚变(ICF)、天体物理学等领域中一种普遍存在的非线性现象.在实验室对射流现象进行模拟、诊断等方面的研究对于理解ICF、天体物理中的相关现象具有重要参考价值.采用纳秒激光辐照特殊形状的圆孔靶产生等离子体射流，利用波长为13.9nm的X射线激光作为光源对特定时刻的射流进行阴影成像，获得了清晰的射流阴影图像，与理论模拟结果定性一致.关键词：射流X射线激光等离子体诊断

| Abstract: | The supersonic jets and the interaction of strong shock waves are ubiquitous features of the nonlinear hydrodynamics of inertial-confinement fusion, astrophysics, and related fields of high energy-density science, so very important value have their studies in laboratory. A laboratories experimental study on jets is reported. The plasma jets were created by an ns laser pulse irradiating a special circular hole target, and the shadow of jets were recorded by using an X-ray laser probe with wavelength of 13.9nm. Legible shadow images of plasma jets were obtained. The experimental results and theoretical simulation were in qualitative agreement. |
