The basic energy balance model is applied to analyze the hohlraum energetics data from the Shenguang (SG) series laser facilities and the National Ignition Facility (NIF) experiments published in the past few years. The analysis shows that the overall hohlraum energetics data are in agreement with the energy balance model within 20% deviation. The 20% deviation might be caused by the diversity in hohlraum parameters, such as material, laser pulse, gas filling density, etc. In addition, the NIF's ignition target designs and our ignition target designs given by simulations are also in accordance with the energy balance model. This work confirms the value of the energy balance model for ignition target design and experimental data assessment, and demonstrates that the NIF energy is enough to achieve ignition if a 1D spherical radiation drive could be created, meanwhile both the laser plasma instabilities and hydrodynamic instabilities could be suppressed.

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。
