一、引言用离子束探针技术测量等离子体电位的方法,曾被美国的 DCX-1装置所采用,也曾被苏联的奥格拉装置上所采用。应用此法测量简单磁镜装置轴向等离子体的电位,要求用径向注入产生等离子体,这是本方法测量的重要条件。我们模拟实验的简单磁镜尺寸约为我们建造的稳态超导磁镜装置的四分之一,磁镜中心 I. INTRODUCTION The method of measuring the plasma potential with ion beam probe technology was used by the DCX-1 unit in the United States and was also used by the Ogla unit in the Soviet Union. This method is used to measure the potential of the axial plasma of a simple magnetic mirror device and requires the radial injection to generate the plasma. This is an important condition for this method. The simple mirror size of our simulation experiment is about a quarter of the steady-state superconducting magnetic mirror we built, the center of the mirror
