摘要:	電漿的電子，離子密度與溫度是了解電離層結構的幾個重要參數，而為了量測這些參數，科學家使用了數種實地量測的技術。本篇論文之目的是自行設計與製作一套太空電漿探針系統。透過國立中央大學太空科學研究所太空電漿模擬艙所產生的電漿，我們可測試與分析自製的電漿探針系統。同時在實驗室內，與將搭載在我國探空七號上之電漿探針進行比較，可評估自製系統之效能。其結果顯示，雖然自製的電漿探針系統其所分析之溫度較高（約 1600 K）且標準偏差較大（約 200 K），但其電流與電壓曲線之穩定度較佳。在未來，可改善電路板之設計，並增加類比轉數位之準確度，將有機會成為太空電漿模擬艙內之基礎量測設施之一。或可進一步安置在未來我國之探空火箭與微衛星進行實地之太空探測。 The electron, ion temperature and density are important plasma parameters for investigating the ionosphere. Several in-situ plasma measurement techniques were used by scientists to obtain these parameters. The purpose of this thesis is to design and develop a space plasma probe system. By using the space plasma chamber owned by the Institute of Space Science of National Central University, experiments were carried out to test and analyze the self-developed space plasma probe system. The performance of the self-developed system is compared with the space plasma probe on board Taiwan’s Sounding Rocket VII. The result shows that although the electron temperature and deviation measured by the self-developed system is higher (about 1600K and 200K respectively), the I-V curves are more stable. In the future, the circuits will be redesigned, and the accuracy of the A/D will be improved to make this system a fundamental facility for the space plasma system. It could even be mounted on rockets or satellites for future space sounding.
