瑞利-泰勒(R-T)流体力学不稳定性 聚苯乙烯 铝 平面调制靶 Rayleigh-Taylor instability Polystyrene Aluminum Surface perturbation target
摘要
介绍了用于侧照明实验研究瑞利-泰勒流体力学不稳定性(Rayleigh-Taylor instability)实验的聚苯乙烯和铝平面调制微靶的制备工艺.通过图形转移,靶型切割和装配工艺的控制,结合靶参数测量,获得了厚度在几十μm、表面具有波长50 μm和55 μm、振幅从几到几十μm、微靶宽度约为200 μm、剖面正弦调制图形清晰的两种靶型.
Abstract
This paper int roduces fabrication of polystyrene and aluminum surface perturbation targets used for flank illumination Rayleigh2Taylor instability experiment . By figure transfer, incising targets, cont rolling constructional technique and measuring targets’ parameters, we obtained surface perturbation target s with sinusoidal surface perturbation figures with thickness of several tens micrometer, the wavelength about 50 micrometer and amplitude f rom several to several tens micrometer. The width of two kinds of eargets is about 200 micrometer and the profile is clear.
