Abstract

Abstract:

Liquid metal, serving as one of the most promising plasma facing components in future fusion reactors, will be controlled by both super annular magnetic field and plasma in high temperature, which will lead liquid metal leaving initial position to fusion core. Three specific instable phenomena are concerned in this paper: 1) sputtering of liquid metal by ion bombardment, 2) splashing of liquid metal under both magnetic and electric fields, and 3) dropping of liquid metal from fusion core onto liquid metal film. The previous researchers had a lot of profound studies on sputtering and droplet dropping onto liquid film,based on which we design new experiments to explore the generation of splash.Our experiments show that liquid metal free surface will gradually grow,and the droplets splash from liquid metal peaks, accompanied by secondary droplet formation.

Key words: liquid metal, sputtering, splashing, magnetic field, electric current
