Be靶丸的研制进展及其关键技术

Fabrication progress and key technologies of Be targets

可控核聚变反应是科学家用来解决能源缺乏和发展可持续能源的理想途径,为此美国开展了惯性约束聚变(ICF)研究,建设了国家点火装置(NIF),旨在实验室演示核聚变反应,为惯性约束聚变能(IFE)发展指明方向。制靶是NIF点火工程三大主体之一,如何制备满足设计需求的靶丸成为科学家不懈努力的追求目标。详细介绍了NIF工程中主要候选Be靶丸需求背景、研究现状、Be靶优势、靶参数设计要点、靶丸制备技术,以及制靶过程中存在的关键技术问题,为我国Be靶制备及制靶能力建设提供参考信息。

The nuclear fusion reaction is an ideal approach to solve the shortage of energy and produce sustainable clean ener gy. The National Ignition Facility device has been built in the United States in order to demonstrate the nuclear fusion reaction. It can provide a clear development direction for the inertial fusion energy. Fabricating target is one of the three main bodies for NIF. How to fabricate an ignition target to meet design requirements becomes tireless efforts of scientists to pursue goals. The objective of this paper is to introduce the requirement background of candidate Be target, research status, advantages of Be target, de sign specifications, preparation technology, as well as some key lechnical issues existing in fabrication process. It will provide an useful reference information for the target fabrication science in our country, and lay a foundation for the ability building of target fabrication.
