The results from 1992 to 1993 are summaried as follows :(1) Magnetic field line tracing by pellet injection.We investigate the temporal response of the ablated particles at the plasma inside, scrape-off layr, and divertor plates.(a) A comparison between the particle traveling and the field line tracing shows a good agreement.(b) Estimated connection length for divertor field lines is - 10m, which is deduced from the delay time measurement.(c) For the particular position, a response is so quick to suggest the stochasiticity near the edge.(d) Global confinement properties affect the propagation of the pulsed density.(2) Density waves by an internal disruption(a) Pulsed density waves are created around the rational surfaces and propagate as an m=0/n=0 mode.(b) They reached to the divertor in a delayd time for density waves to diffuse out from the rational surface to the edge.(c) For particular positions a response is so quick to suggest the stochasiticity near the edge.

1992 ~ 1993年的主要结果如下：（1）弹丸注入的磁力线追踪：研究了烧蚀粒子在等离子体内部、刮削层和偏滤器板上的时间响应。(a)将粒子的运动轨迹与场线追踪结果进行了比较，结果表明两者吻合较好。(b)偏滤器场线的估计连接长度为-10米，这是从延迟时间测量中推导出来的。(c)对于特定的位置，反应是如此之快，以表明边缘附近的随机性。(d)整体约束特性影响脉冲密度的传播。(2)（a）在有理曲面周围产生脉冲密度波，并以m=0/n=0模式传播。(b)它们到达偏滤器的时间要比密度波从有理表面扩散到边缘的时间要晚。(c)对于特定的位置，反应如此之快，表明边缘附近的随机性。
