Fabrication of dual-media CRF/CH cylindrical target
摘要
Abstract
The fabrication procedures of dual-layer cylindrical carbonized resorcinol formaldehyde(CRF) aerogel/polystyrene (CH) target were investigated. The organic cylindrical RF aerogel was synthesized by using sol-gel process and micro-shaped method, the cylindrical CRF aerogel was prepared by pyrolyzing the cylindrical RF aerogel under the protection of nitrogen. The density and diameter of cylindrical CRF aerogel were about 250 mg · cm-3 and 730 μm. The dual-media CRF/CH target with the length of about 1 mm and inner diameter of 730 μm was formed by using dip-coating and micro-cutting process. The preparation process of cylindrical RF and CRF aerogel was discussed. The scanning electron microscope(SEM) was used to measure the mi-crostructure of cylindrical RF and CRF aerogel and the interface between CH and CRF aerogel. The density homogeneity of the axis and diameter direction of cylindrical CRF aerogel was characterized by X-ray phase contrast image apparatus. The surface roughness of CH film was measured by Alpha-step 500 profiler. The influence factors on the thickness of CH film were investiga-ted.关键词
