Quantitative Laboratory Studies for Proton Auroral Analysis

为了了解高能质子对大气的影响，需要确定高能氢原子以及O和O2等大气成分的定量排放量。到目前为止，这类信息还很缺乏，这项资助的目的是利用实验室技术和对过去实验室数据的分析，提供光谱中紫外线、可见光和近红外部分的基本信息。该研究将确定高能氢发射H （α）、H （β）和L （α）的概率，以及目标物质（如O、O2或N2）产生的其他发射。鉴于实验室电场对实验室横截面实验中光子测量的重要性的新数据，许多旧的粒子碰撞实验室数据也将被重新评估。这项研究的总体目标是了解极光粒子束与地球大气的相互作用。

In order to understand the impact of energetic protons upon our atmosphere the quantitative yield of emissions from energetic H atoms, as well as atmospheric constituents such as O and O2, needs to be determined. To date there is a paucity of such information and this grant is aimed at providing this fundamental information in the ultraviolet, visible and near-infrared portions of the spectrum using laboratory techniques and analysis of past laboratory data. The study will determine the probability of emission of H (alpha), H (beta) and L (alpha) from energetic hydrogen as well as other emissions arising from the target specie, such as O, O2 or N2. In light of new data on the importance of laboratory electric fields on the photon measurements in laboratory cross-section experiments, much of the old particle collision laboratory data will also be reevaluated. The overall aim of this research is to understand the interaction of the auroral particle beam with the terrestrial atmosphere.
