这项研究针对尘埃等离子体中的两个实验问题。第一个涉及尘埃云和背景等离子体之间的边界,第二个涉及尘埃等离子体的动力学(尘埃速度分布)。除了基本的等离子体物理成分外,边界研究对学习如何操纵尘埃云也很重要。这项研究的关键诊断是粒子图像测速(PIV),这是由PI首创的,用于研究等离子体中尘埃颗粒的运动(通过不同时间拍摄的图像的相互关联)。
英文摘要
The research is directed toward two experimental issues in dusty plasmas. The first involves the boundary between dust clouds and the background plasma and the second the kinetics of dusty plasmas (the dust velocity distribution). The boundary study is important to learning how to manipulate dust clouds, in addition to the basic plasma physics component. The key diagnostic in the study is particle image velocimetry (PIV), which has been pioneered by the PI for study of dust grains motion in plasmas (through the cross-correlation of images taken at different times.
