Teaching content

Fine solid particles (Dust particles) including impurity atoms are generated in the periphery of high temperature plasmas in the Large Helical Device (LHD). In this exercise, students learn the technique for analyzing the traces of dust particles observed with a stereoscopic fast-framing camera system and master the method for obtaining the three-dimensional trajectories of the dust particles. Additionally, the students learn the visualization technique of the dust particle trajectories in the LHD plasma by displaying the analysis results in the three-dimensional virtual reality (VR) system and experience the high visualization performance of this system.
