摘要
文章主要介绍了国内自2000年以来的激光惯性约束聚变(ICF)实验研究以及诊断技术研究的进展,主要内容为神光Ⅱ激光装置上的实验,也对刚建成不久的神光Ⅲ原型装置上的实验作简要介绍,此外,文章还介绍了神光Ⅱ和神光Ⅲ原型装置上近期发展的诊断技术和设备.文章作者在神光Ⅱ激光装置上开展了多项的物理实验研究,其中包括黑腔物理、内爆物理、流体动力学不稳定性、辐射不透明度以及辐射驱动冲击波等,并取得了重要的进展.在X射线单能成像、Thomson探针、无高级衍射的单级衍射光栅等新型关键诊断技术与尖端设备研制方面也取得了显著进展.
The experiments and diagnostic techniques for inertial confinement fusion（ICF） on the Shenguang laser facility since 2000 are reviewed.Many experiments were conducted on the Shenguang Ⅱ（SG-Ⅱ） and Shenguang Ⅲ prototype（SG-ⅢYX） laser facilities.The SG-ⅢYX was completed in 2006.The experiments on SG-II included several physics experiments on topics such as hohlraum physics,implosion physics,fluid dynamical instability,opacity,and shocks driven by radiation.The experimental results indicated that significant achievements were acquired on SG-Ⅱ.The ICF experiments were conducted on SG-ⅢYX after it was finished.The first experiment,which included Holhraum and implosion physics,was performed in 2007.The integrated diagnostic systems for SG-Ⅱ and SG-ⅢYX have been built,as well as the X-ray monochromatic imaging instrument,Thomson probe,transmission grating without higher order diffraction,and so forth.These characteristic diagnostic techniques are important for improved measurement accuracy.
