摘要

A polystyrene (CH)/carbonized resorcinol formaldehyde (CRF) dual-layer perturbation target for inertial confinement fusion hydrodynamic instability experiments was designed and fabricated. The target was composed of a perturbed CRF aerogel sheet and a CH layer. The detailed fabrication method consisted of three steps. The CRF aerogel sheet was first prepared by sol-gel and carbonization processes; the perturbation patterns were then introduced on the surface of the CRF aerogel sheet by a laser micro-machining process; finally, the CH layer was directly coated on the perturbation surface by a spin-coating process not only to avoid the use of a sticker but also to eliminate the gaps between the CH layer and the CRF aerogel sheet. A scanning electron microscope was used to investigate the surface morphology and microstructure of the CRF aerogel sheet. The parameters of the target, such as the perturbation period (T), perturbation amplitude (A), thickness of the CRF aerogel sheet (H_1,) and thickness of the CH layer (H_2), were characterized by a QC-5000 tool microscope. The cross-sectional photographs of the target showed that the CH layer and the CRF aerogel sheet adhered perfectly with each other. The influence of the laser micro-machining process on the microstructure of the CRF aerogel sheet was studied. T and A of the target were about 100μm and 20μm while H_1 and H_2 were about 250μm and 30μm, respectively. The total thickness and width of the target were about 260μm and 250μm, respectively.
