Modulation targets in Rayleigh-Taylor instability experiments for the ICF study

Designs of targets used in the current Rayleigh-Taylor instability experiments are analyzed and summarized in this paper. The preparation of the perturbation target is developing from two-dimensional to three-dimensional. New designs such as spheric and cylindrical target appeared. Preparation techniques include micromachining, laser, electron and iron beam etching, semiconductor technology, and nano-technology. Laser two-beam interference and electric plating technique for planar target fabrication is studied. According to the novel foreign designs as well as domestic conditions and need, possible designs for recent use such as rapid prototyping and EDM technique for cylindrical target and laser machining technique for spheric target fabrication are proposed.
