HT-7托卡马克slide-away放电充气对等离子体行为的影响
The effect of gas puffing on plasma during slide-away discharge in the HT-7 tokamak
摘要
Abstract
In tokamak plasma,the discharge will turn into ＂runaway＂ discharge from normal discharge if the plasma density becomes very low.The discharge will enter into ＂slide-away＂ discharge if the density decays to a critical one,in which the confinement of plasma （exactly supper thermal electrons） is better than that in normal discharge.The confinement of plasma and the anomalous Doppler instability during slide-away discharge gas puffing are investigated.The effect of gas puffing on runaway electrons during slide-away discharge is also studied in this paper.It is found that the anomalous Doppler instability can be suppressed by the gas puffing during slide-away discharge,while the confinement of plasma becomes poor,and many high energy runaway electrons occur during gas puffing.关键词
