摘要:

用HL-2A装置下偏滤器靶板上的14组嵌入式静电三探针阵列和外偏滤器室的电动扫描四探针组,测量了同一环向截面的内外中性化板上的电子温度、密度、悬浮电位及其分布,以及电子回旋加热(ECRH)实验期间的等离子体行为。研究了偏滤器中等离子体参数的分布及非对称性以及等离子体的形成、物理特性和改善粒子的约束特性。

Abstract:

The divertor plasma characteristics are studied by means of electro-motion scanning 4-probes in the outer divertor chamber and the fixed flush probe arrays on the 4 divertor neutralization plates at the same toroidal cross-section in the HL-2A tokamak. They provide important parameters for investigation of distribution and asymmetric of plasma parameter in the divertor. The profiles of energy or particle flow and their decay lengths can be estimated by the target temperature and density. They are very useful to investigate plasma behavior and physical characteristic in the divertor mode. These results identify that divertor can improve the particle confinement.

Key words: Divertor, Flush probe, Electromotion scanning probes
