朗缪尔探针是进行空间等离子体电子密度和温度就位测量的重要仪器,在电离层卫星探测和火箭探测中应用十分广泛.传感器设计的合理与否是影响朗缪尔探针探测结果的关键因素之一.朗缪尔探针传感器的结构本身比较简单,但传感器的设计要受到多种物理条件及工程条件的限制,其中,有些限制条件相互制约甚至相互矛盾,必须综合进行考虑.从传感器形状、大小和表面材料的选取三个方面分析了朗缪尔探针的各种限制条件,给出了一种原型朗缪尔探针的设计,并通过仿真计算验证了该设计.
Langmuir probe is an important instrument for measuring the density and temperature of space plasma in situ and is widely used in ionosphere satellite and rocket detection.Whether the sensor design is reasonable or not is the result of Langmuir probe detection One of the key factors is the structure of the Langmuir probe sensor itself is relatively simple, but the sensor design is subject to a variety of physical conditions and engineering conditions, of which some of the constraints or even mutually contradictory constraints must be considered. Sensor shape, size and surface material selection of three aspects of the Langmuir probe constraints, gives a prototype of the Langmuir probe design, and verified by simulation calculations of the design.
