摘　　要：介绍了用于流体力学不稳定性实验的聚苯乙烯(CH)/Al双介质调制靶的制备方法。采用激光微加工工艺在50μm厚Al箔表面制备了调制周期为55μm、峰谷差为4.7μm的调制图形;采用旋涂工艺在Al箔表面制备了20μm厚CH薄膜,经过后期的微切割、微装配工艺,得到了宽度为200μm、总厚度为70μm的CH/Al双介质调制靶。该靶型于2010年在"神光-Ⅱ"激光装置中进行了流体力学不稳定性实验。The fabrication procedures of dual-layer polystyrene（CH）/Al perturbation target were investigated.Perturbation patterns were introduced onto Al foil with thickness of 50 μm by laser micro-machining process,and the period and amplitude of the patterns were about 55 μm and 4.7 μm,respectively.CH film with thickness of 20 μm was directly coated on the surface of patterned Al foil by spin-coating process.The dual-layer CH/Al perturbation target was prepared by micro-cutting and micro-assembling process.The width and thickness of the target were about 200 μm and 70 μm,respectively.The target had been performed at ＂SG-Ⅱ＂ laser facility to investigate hydrodynamic instability in 2010.
