中文摘要 1964年Balmain 計算出探針在均勻磁化電漿環境裡的阻抗,然而在1966年 Oya 藉由此計算研發出阻抗探針。 (Oya 一開始稱這種探針叫做 “gyro-plasma probe”)。
阻抗探針系統是效能非常好的太空儀器,使用在量測電離層電漿最基本的參數之一(電子濃度)。本篇論文的目的是在台灣未來的電離層量測任務中,發展國內自己研發的阻抗探針系統。在這篇論文中,我們推導出阻抗探針的原理並設計它的電路系統,使此系統能在離地表120km 到 1000km 的高空中進行量測任務。我們已經研發出三種不同的阻抗探針系統,並在國立成功大學(電漿中心)裡的太空電漿腔進行量測實驗比較其優缺點。
英文摘要 The impedance probe was realized by Oya (1966) who was inspired by the calculation of probe impedance in plasma by Balmain (1964) (Oya called this probe as “gyro-plasma probe” initially).
The impedance Probe system is a powerful instrument for measuring the electron density, which is one of the fundamental parameters in the Ionosphere. The purpose of this thesis is to develop impedance probe for future ionosphere survey missions in Taiwan. In this thesis, we have derived the principle of the impedance probe and designed the electric circuit system to measurement the electron density in the altitude range of 120km to 1000km in the ionosphere. We have developed three different impedance probe systems and compared their performance in the Space Plasma Operation Chamber at the Plasma and Space Science Center of the National Cheng Kung University.
