Preparation and Research Development of Resorcinol Formaldehyde Hollow Foam Microspheres Used for Laser Fusion Targets

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.
