摘要
测量了HL 1M装置上正弦周期调制馈气方法诱发的密度扰动 ,采用了简单的数值方法求解粒子输运方程来计算密度扰动 ,并与密度扰动的测量结果进行了比较。得出欧姆加热时等离子体芯部的粒子扩散系数为0 2± 0 .1m2 ·s- 1 ,边缘粒子扩散系数为 1 0± 0 .2m2 ·s- 1 。
Measurements of the density perturbation induced by the sinusoidal modulation of gas puff injection have been performed in the HL-1M plasma.The particle transport equations have been analyzed by using a simplified numerical method.The measuring results and the calculated ones have been compared with each other.The particle diffusion coefficients in the core region were evaluated to be 0.2±0.1m 2·s -1,and those in the edge region 1.0±0.2m 2·s -1 for ohmical plasmas.
