Solar Energetic Neutral-atom Code Mask Imager
摘要
Abstract
A general design of Solar Neutral Atom code mask Imager (SNAI) is proposed for the Kuafu space weather exploring plan.The instrument is designed to measure the solar Energetic Neutral Atoms (ENA) emitted from the solar flare or CME.The differential energy spectrum of ENA is between 0.5 MeV and 6 MeV,and the FOV of ENA is 360° × 10°.This instrument combines innovative sensor geometry,an m sequence coding mask modulation aperture,and a combination of high voltage deflecting plate of active and passive shielding charging particles to obtain ENA in space flight.The coded imaging scheme and its simulation have laid the technical foundation for the coronal neutral atom imaging observation,which will provide the technical supports for the study of space weather.关键词
