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.
