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 article mainly introduces the experimental research on laser inertial confinement fusion (ICF) in China and the research progress in diagnostic technology since 2000. The main contents are the experiments on SG laser device, and also on the newly built SG-III prototype device In addition, the article also introduced the recent development of diagnostic techniques and equipment on the SG-Ⅱ and SG-III prototype devices.The author carried out a number of physical experimental studies on SG-II laser devices, including Black cavity physics, implosion physics, hydrodynamics instability, radiation opacity and radiation-driven shock wave, and made significant progress.An X-ray single imaging, Thomson probe, single-stage diffraction grating without advanced diffraction And other new key diagnostic techniques and cutting-edge equipment development has also made significant progress.
