在欧姆放电、超声束流注入(SBI)和多发弹丸注入(MPI)期间,利用马赫/朗缪尔探针组测量了HL-1M装置刮削层和边界层的边缘电场和等离子体旋转;环向马赫数Ma、极向流速度vpol和电场Er的径向分布是分别在超声束注入和多发弹丸注入期间进行测量的。超声束注入和多发弹丸注入对边缘电场、等离子体旋转和扰动水平的影响已观测到,结果给出等离子体边缘的径向电场Er产生了变化并变得更负。在超声束注入和多发弹丸注入期间,测得电子反磁方向上的极向旋转速度分别为3.8km·s-1和10km·s-1,以及等离子体边缘的径向电场分别为-8kV·m-1和-14kV·m-1。这就意味着,极向旋转速度主要取决于E×B漂移。
During the ohmic discharge, ultrasonic beam injection (SBI) and multiple shot injection (MPI), the edge electric field and plasma rotation of the scraping and boundary layers of the HL-1M device were measured using a Mach / Langmuir probe set; The radial distribution of the Mach number Ma, the poloidal flow velocity vpol, and the electric field Er is measured during ultrasonic beam injection and multiple shot injection, respectively. The effects of ultrasound beam injection and multiple shot injection on the fringing electric field, plasma rotation and perturbation levels have been observed, resulting in a change in the radial electric field Er at the edge of the plasma that has become more negative. During ultrasonic beam injection and multiple shot injection, the measured polar velocities in the anti-magnetic direction were 3.8km · s-1 and 10km · s-1, respectively, and the radial electric field at the plasma edge was -8kV · M-1 and -14kV · m-1. This means that the polar rotation speed mainly depends on the E × B drift.
