美国在国家点火攻关计划(NIC)的实施尽管未能实现点火目标,但建立了前所未有的点火靶物理精密实验能力,深化了点火靶物理认识,进一步明确了需要进一步解决的关键问题。激光聚变研究中心利用神光Ⅱ和神光Ⅲ原型装置条件,围绕黑腔等离子体能量学和内爆动力学开展实验与诊断技术研究,部分关键诊断技术取得突破,精密的实验能力显著增强,进一步丰富的配套实验结果在深化靶物理认识和校验数值模拟程序方面发挥了重要作用。

Although National Ignition Campaign (NIC) has not achieved the milestone goal of ignition, National Ignition Facility (NIF) has established unprecedented ability of experimental physics on ignition, high energy density physics and basic science by integrating laser performance, target diagnostics and target fabrication. With extraordinary capabilities, NIF researchers have designed delicate experiments to clarify physical understanding and specified several issues which are crucial to the ignition physics. While in Research Center of Laser Fusion, hohlraum energetics and implosion hydrodynamics have been studied extensively on Shenguang-Ⅱ and Shenguang-Ⅲ prototype laser facilities in recent years. Physical experiments employ several high precision diagnostics in resolving different photon range and multiple viewing areas. These detailed and accurate data have improved our understanding of target physics, and help to validate our radiation-hydrodynamic code.
