| 摘 要： | 通过变换工作气体(氢气和氘气的相互转换)研究了HT-6M托卡马克中等离子体的再循环。用光谱方法(Balmer线)跟踪了放电中等离子体浓度的相对变化。结果表明,等离子体在壁处的反射系数约为0.59,变换工作气体后,在第一次放电的等离子体中,由壁释放的同位素含量约占65％。讨论了HT-6M托卡马克中再循环的物理机制。关键词：

| Abstract: | Recycling in the HT-6M tokamak is studied by changing the working gas from deuterium to hydrogen and vice versa. Spectroscopic technique (Balmer lines) is used to follow the change of the relative concentration of the plasma. The results show that the reflection coefficient near the wall is about 0. 59, and in the plasma of the first discharge after a gas change, the wall-released isotope amount to 65% .The recyclingc mechanism in the HT-6M tokamak is discussed. |
