摘要：

Electron density is one of the important parameters of plasma. In the aerospace field, the density distribution of plasma on the surface of an aircraft will have an important effect on it. In this field, the current research mostly stays in the laboratory stage or static electron density diagnosis stage, and there is still a certain distance from the actual application. This study is based on the traditional Langmuir probe theory and follows the assumptions of the Langmuir probe theory to make a qualitative analysis of its voltammetric characteristics. Based on the above analysis, a single flush-probe was designed, and a method for diagnosing electron density for low pressure was proposed. It was verified by experiments that the method can accurately obtain parameters of plasma such as electron density in the low pressure range, which can provide a certain reference for future electronic density diagnosis in the aerospace.
