摘要
在惯性约束聚变研究中,RF空心泡沫微球具有低原子序数(Z)、低密度(ρ)可以降低辐射驱动内爆过程中燃料预热及流体力学不稳定性、提高实验增益,并且由于光学透明性便于实验过程的诊断,成为以后直接驱动点火的首选靶材料。综述了几种制备方法的基本原理、成球过程控制、在惯性约束聚变制靶中的地位及RF空心微球的国内外发展现状及研究进展。
In the study of ICF, resorcinol formaldehyde hollow foam microspheres which have low density and low atomic number may decrease the instability of preheated fuel and hydro mechanics in the course of radiant drive impolsion and increase the efficiency. And it is available to diagnose in experiment because of its transparent. Therefore, RF hollow microspheres are preferred terget materials in driect drive experiments. The basic mechanism, the RF shell process control, and the research status and development of several preparation methods in the target preparation experiments in innertial confinement fusion are outlined.
