PS-PVA-CH微球惯性约束聚变充气充气平衡温度 PS-PVA-CH microsphere Inertial confinement fusion（ICF） Gas-filling Gas-filling temperature

摘要

主要研究了PS-PVA-CH空心塑料微球充气时,充气平衡温度对微球强度、球形度和表面形貌的影响.对PS,PVA和CH材料的热重分析结果表明,PS和PVA具有较高的分解温度,而PS-PVA双层球和PS-PVA-CH塑料微球升温后的耐外压实验表明,温度升高后双层球耐外压强度降低很快,不能满足充Ar气需要;而3层球在100～120℃仍有很高强度,在该温度下,可以实现充Ar气.微球表面形貌分析结果显示,高温充气后,3层球表面粗糙度升高.

Abstract

The basic target used in many inertial confinement fusion(ICF) experiments is a hollow microsphere of glass or plastic. Generally, the hollow plastic microsphere is composed of three layers: polystyrene(PS), polyvinyl alcohol(PVA) and carbon hydrogen(CH).This paper focuses on the filling-gas temperature effects on the PS-PVA-CH hollow plastic microsphere properties such as the shell strength and the surface quality. Experiments show that although the material of PS and PVA has high decomposed temperature the strength decreases rapidly as the temperature increases. The PS-PVA shell strength is not enough for Ar-filling. After coating the CH ablator the microsphere can be filled with Ar at 110℃.
