蘭摩爾探針系統是最廣泛使用在量測電漿最基本的兩個參數(電子溫度及濃度)的方法。
本篇論文主要的研究目地是發展一套蘭摩爾探針系統用在台灣國家太空中心的探空火箭上，探空火箭計畫是台灣一項重要的電離層科學實驗，這套蘭摩爾探針系統就是這次探空十號火箭五項科學儀器的其中一項儀器，此系統主要元件包含有探針、量測電路、訊號控制擷取系統、火箭酬載區載台裝置、旋轉施放裝置等。使用太空電漿模擬艙，我們藉由實驗測試蘭摩爾針系統的問題並驗證系統之設計目標。

Langmuir Probe system is widely used to measure the electron temperature and density, which are two of the basic parameters in the space plasmas. The purpose of this paper is to present a Langmuir probe system, which will be deployed for a Sounding Rocket experiment supported by the National Space Program Office (NSPO). The Sounding Rocket experiment is a coordinated space scientific experiment to study the ionospheric plasma over the Taiwan region. The Langmuir probe system is one of the science instruments of the Sounding Rocket experiment which consists of two sets of Langmuir probes, a Magnetoresistive Magnetometer, a flux-gate Magnetometer, an Ion Energy Analyzer, and a neutral Particle Analyzer. The Langmuir probe system consists of a senor part, detection electronic circuits, and a signal control and data acquisition system, a deployment system that has a wire-cutting system for breaking the glass that seals Langmuir probe from moisture. By testing the Langmuir probe system in the space plasma chamber, we have identified problems associated with the Langmuir probe electronic circuits and data acquisition associated with the Langmuir probe measurement. The Langmuir probe system is now validated with the design goal.
