利用马赫-郎缪尔探针组研究了HL-1M装置刮离层和边缘等离子体流在欧姆放电、中性束注入、低杂波注入、离子回旋加热和电子回旋加热等情况下的极向流速、径向电场和极向电场的变化与分布,研究并讨论了它们对降低边缘粒子径向传输和改善等离子体约束性能的影响。
The Mach-Langmuir probe set was used to study the polarization direction of the scraped layer and the edge plasma in the HL-1M device under the conditions of ohmic discharge, neutral beam injection, low noise injection, ion cyclotron heating and electron cyclotron heating Flow velocity, radial electric field and poloidal electric field, the influence of radial force and radial electric field on the radial transfer and the improvement of plasma confinement performance are studied and discussed.
