| 摘 要： | 等离子体电位是托卡马克装置的一个重要参数。它的测量在放电机制、等离子体的平衡与稳定、等离子体-表面相互作用以及杂质控制等研究课题中有着极其重要的作用。 本文描述用朗谬尔探针,以及由它组成的对称双探钎系统(以下简称SDP系统)测量微环托卡马克边界区等离子体电位V_0的两种方法和结果。

| Abstract: | The plasma potential in Mini-Torus has been measured using Langmuir probes and a "SDP" probe system which is formed of these probes. The measurement shows that the plasma edge in Mini-Torus is potentially positive relative to the vessel wall, and under the present operating condition, the radial electric field strength is about 15V/cm. The rotation of the plasma column in this device is analysed. The result is in accord with high speed photograph measurement . |
