碩士 === 國立成功大學 === 物理學系碩博士班 === 100 === In the thesis, we report the development of an Aurora Electron Spectrometer (AES) to measure the electron energy distribution in the 10eV - 20keV energy range with 40ms time resolution for full energy scan with 32 energy steps for deployment in the upper ionosphere above the aurora arc. AES also measures the full particle pitch angle distribution with 16 azimuthal channels. For this purpose, a combination of top-hat electrostatic analyzer and micro-channel plate (MCP) is adopted measure particle flux. Two major focuses of this work are: 1. AES Design by numerical simulations: Numerical simulations are performed to estimate the AES performance with different design parameters and the best design is determined for the AES fabrication. 2. Performance check of AES by experiment: A prototype of AES has been built and its performance has been checked by conducting calibration test using the beam line system at the Plasma and Space Science Center (PSSC) of National Cheng Kung University (NCKU). The experiment results are compared with the simulation results. The differences between the experiment and the simulation are investigated.
