通过中平面活动10探针组、往复快速扫描4探针和低杂波天线口的固定4探针测量了主等离子体边缘的温度、密度、悬浮电位、径向和极向电场、雷诺协强、径向和极向等离子体流速及其径向分布。用偏滤器靶板上的14组嵌入式静电3探针阵列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。比较了在孔栏位形和偏滤器位形下边缘等离子体特性的差异,特别是两种位形下边缘温度和密度衰减长度的变化。分析了在多脉冲超声分子束加料和低杂波注入条件下的边界等离子体特性,以及雷诺协强的径向梯度与极向流和径向电场梯度与湍流损失的相互关系。
The temperature, density, levitation potential, radial and poloidal electric fields at the edge of the main plasma were measured by a mid-plane active 10 probe set, a reciprocating fast scanning 4 probe and a fixed 4 probe at the low clutter antenna port. , Radial and polar plasma velocities and their radial distribution. The electron temperature, density, levitation potential and their distribution on the inner and outer neutral plates with the same ring cross section were measured with 14 sets of embedded electrostatic 3 probe arrays on the divertor target. The differences of the plasma properties between the bottom of the column and the bottom edge of the divertor configuration are compared, especially the change of the temperature and the density attenuation length of the bottom edge of the two configurations. The characteristics of the boundary plasmas under multi-pulsed ultrasonic molecular beam injection and low-noise injection are analyzed, and the relationship between Reynolds-enhanced radial gradient and poloidal flow and radial electric field gradient and turbulence loss is analyzed.
