| Summary: | 碩士 === 國立中央大學 === 太空科學研究所 === 99 === In order to understand the phenomena in the ionosphere, one of the important methods is the in-situ measurement which acquires plasma parameters directly from the plasma. There is existence of both neutral gas and space plasma in the ionosphere, making electron temperature and density important parameters. The purpose of this thesis is to develop an electron temperature probe which can be applied to measure plasma electron temperatures in space environments such as the ionosphere. By using the space plasma simulation chamber located at the Institute of Space Science, National Central University, electron temperature probe experiments were carried out. Data was recorded for further analysis and discussion. The effects of the two different energy species of plasma produced by the diffusion mechanism of the space plasma simulation chamber made to the measurements were discussed. The results implied the electron temperature probe is sensitive to the plasma dynamic impedance and other nearby instrumentations. Lastly, it is shown that the generation of the sweeping voltage and impedance matching with the plasma made differences to the measurements of electron temperatures.
