| 摘 要： | 为了研究惯性约束聚变(ICF)实验用靶丸不同密度界面的流体力学不稳定性增长,设计并制备了聚苯乙烯(CH)/碳气凝胶(CRF),CRF/硅气凝胶(SiO2)和CH/Al三种双介质调制靶。采用溶胶-凝胶工艺制备了密度分别为250和800mg/cm3的CRF气凝胶薄片;采用激光微加工工艺分别在两种不同密度的CRF薄片和工业用纯Al箔上引入调制图形;采用旋涂工艺在Al箔和CRF薄片(250mg/cm3)的调制表面制备一层CH薄膜,得到CH/Al和CH/CRF双介质调制靶,采用溶胶-凝胶工艺在CRF薄片(800mg/cm3)表面制备一层低密度SiO2气凝胶,得到CRF/SiO2双介质调制靶。采用电子天平、扫描电子显微镜、工具显微镜和台阶仪对所制备的CH/CRF,CRF/SiO2和CH/Al三种双介质调制靶进行靶参数测量。结果表明:三种双介质调制靶层与层之间结合紧密,界面清晰,调制图形为正弦,靶参数测量准确。

| Abstract: | The polystyrene (CH)/carbonized resorcinol formaldehyde (CRF), CRF/SiO2, CH/Al dual-layer perturbation targets for ICF resolved experiment were investigated. The CRF aerogel sheets with a density of 250 and 800 mg/cm3 were synthesized by sol-gel process. As the seed of the growth of hydrodynamic instability, the perturbation patterns were introduced onto the surface of CRF aerogel sheets and Al foil by laser micro-machining process. The CH films were directly coated on the patterned surface of CRF aerogel sheets(250 mg/cm3) and Al foil by spin-coating process while the SiO2 aerogel sheet was prepared on the CRF aerogel sheets(800 mg/cm3) by sol-gel process. The target parameters of CH/CRF, CRF/SiO2 and CH/Al dual-layer perturbation target were characterized by electro-balance, scanning electron microscope, tool microscope and surface profiler etc. The results indicated that the dual-layer perturbation target had good combination with clear interfaces, the perturbation patterns in the interfaces were sine, while the parameters were precisely measured. |
