从1997年开始,日本大阪大学激光工程研究所就一直从事快点火实验和理论方面的研究,特别是关于预设金锥靶的实验和模拟研究。为了演示内爆高密度等离子体的加热,和达到点火所需的温度,2003年4月,用于FIREX-Ⅰ(Fast Ignition Realization Experiment的加热激光器——LFEX开始建造LFEX,Laser for Fusion Experiment,10kJ/10ps/1.06μm)。另外大阪大学和日本国家聚变科学研究所联合对DT泡沫状低温锥形靶进行研究。LFEX装置将在2008年建设完成,到时,泡沫状低温锥形靶的相关实验将会开始。作为小型化点火的新方法,人们提出了碰撞聚变,该方法的关键是如何加速到108cm/s量级,与碰撞聚变相关的烧蚀加速正在进行实验研究。
Since 1997, the Institute of Laser Engineering, Osaka University, Japan has been engaged in rapid fire experiments and theoretical studies, in particular, experiments and simulations on preset gold cone targets. To demonstrate the heating of the implosion high-density plasma and the temperature required to ignite it, in April 2003 a heating laser for FIREX-I (Fast Ignition Realization Experiment - LFEX started to build LFEX, Laser for Fusion Experiment, 10kJ /10ps/1.06μm). In addition, Osaka University and Japan’s National Institute of Fusion Research jointly researched DT foam-like low-temperature cone targets. The LFEX installation will be completed in 2008 and the relevant experiments on the foamy low temperature cone target will begin. As a new method of miniaturization ignition, collision fusion has been proposed. The key of this method is how to accelerate to the order of 108 cm / s. Experimental accelerations related to collision fusion are undergoing experimental studies.
