[PEM36-P14] 超高層大気の組成・速度分布測定のための中性大気分析器の開発：質量分析部の性能評価試験
キーワード：超高層中性大気, 速度分布関数, 質量分析
In order to understand the temporal and spatial variability of the ionosphere-thermosphere system, simultaneous measurements of the composition and density of the neutral atmosphere and the velocity distribution of individual species are essential. However, most conventional types of instruments for neutral atmosphere lack the simultaneous capability of measuring neutral atmospheric velocity and resolving neutral mass.
We have designed the Atmospheric Neutral Analyzer (ANA) instrument to measure the detailed, mass-resolved 2-dimensional velocity distribution of neutral species, from which the corresponding density, mass composition, bulk velocity and temperature were derived. In this presentation, we will report the results from laboratory experiments for the performance verification on the prototype of mass analyzer along with the detailed and overall design determined by numerical simulation.
