利用ECE电子回旋辐射和Ha线辐射等托卡马克物理诊断系统,研究了Slide-away放电过程中提高等离子体密度对非麦克斯维尔分布的逃逸电子所激发的逃逸电子束不稳定性影响作用.实验结果表明:在Slide-away放电模式下,提高等离子体密度能有效抑制逃逸电子束的不稳定性.
The effect of plasma density on the escape electron beam instability induced by the escape electrons with non-Maxwellian distribution during Slide-away discharge was studied by using Tokamak physical diagnostic system such as ECE electron cyclotron radiation and Ha radiation. The experimental results show that increasing the plasma density can effectively suppress the instability of the escape electron beam in the Slide-away discharge mode.
