摘　　要：能源与环境是人类社会与经济发展的基础。传统的化石能源与现代的核裂变能源往往造成严重的环境污染,其原料也终将枯竭、难以持续;受控热核聚变能以用之不竭的海水作为原料,环境友好,将是未来彻底解决能源与环境问题的主要希望所在。强激光或重离子束驱动的惯性约束核聚变是实现受控热核聚变的重要途径。当前,美国激光聚变装置已经实现聚变能增益;我国的"神光"系列激光聚变研究采取循序渐进的思路,也已进入攻坚阶段。与此同时,国内外大型重离子加速装置项目相继启动,相关的现代加速器技术飞速发展,以高功率重离子束为驱动源、以现代加速器为先进工具的惯性约束聚变物理研究,条件日益成熟,亟待大力发展和推动。文章主要介绍基于现代加速器的惯性约束聚变物理领域若干前沿课题的研究现状和新进展。Energy and environment is the foundation of human social and economic devel- opment. Both the traditional fossil energy and the modem nuclear-fission energy always cause envi- ronment pollution, in addition that the sources will run out sooner or later. As a kind of clean, sus- tainable and enviriment-friendly energy sources, the controlled thermonuclear fusion energy, with sea-water as the source, is the most promising solution to the energy and environment problem. In- tense laser or heavy ion beams are the important ways to achieve inertial confinement fusion. The National Ignition Facilities in US has got energy gain from fusion, while the Chinese ShengGuang laser fusion facilities, taking a gradual stread, has entered a critical stage. At the same time, as the developing of the modem accelerator technique and the lauching of laser scale heavy ion accelera- tor facility, the conditions for inertial fusion research based on accelerator facilities are gradually ripe and urgently need to be pushed forward. Here in this article, the status and perspectives for the studies of inertial confinement fusion based on modem accelerators are reported.
