ICF靶用微球弹跳的影响因素分析

 通过对微球弹跳模型的建立，对微球弹跳过程进行了受力分析，解释了微球弹跳过程中遇到的微球粘连或“不跳”、弹跳率起伏不定及弹跳幅度高低不同等现象。通过对加载信号方向与大小、微球质量及尺寸大小、微球及反弹盘表面特性、环境湿度等影响微球弹跳效果因素的分析，提出了改善涂层表面粗糙度和弹跳效果的措施,包括根据微球大小调整微球弹跳激励方式、等离子体中和微球表面电荷、反弹盘表面改性减小球盘之间的相互作用力。

Effecting factors on bounce of inertial confinement fusion microshells

Analysis of forces on microshells during ablation layer bounce-coating has been carried out based on the established bouncing and mechanical models. The phenomena, such as the conglutination and unbounce of microshells, the fluctuation of the bounce amplitudes and bounce rates, have been explained. Through the analysis of effecting factors on the bounce of microshells, such as the direction and the magnitude of the stimulating signal, the mass and size of microshells, the surface characters of microshells and bounce-pan, the humidity and dirty of environment, etc, serious solutions which can improve bounce-effect of microshells have been put forward. The solutions include the stimulating signal adjustment, the plasma treatment and the surface modification of the bounce-pan.
