This project will analyze data taken from the MeV Auroral X-ray Imaging and Spectroscopy (MAXIS) 2000 long-duration balloon campaign. The balloon was launched from McMurdo, Antarctica. It detected two types of high-energy (relativistic) particle precipitation, (1) MeV precipitation events and (2) microbursts. The analysis will examine the sources and particle energization mechanisms responsible for these two different types of events. The observational data will be put into context by comparing the observations with different models of the processes by which particles are energized and then scattered into the loss-cone so that they are observed as precipitating particles. In addition to the purely scientific aspects of the research, the project will enhance education by including undergraduates in the research program and the Dartmouth College Women in Science Project (WISP) will help enhance diversity in space science.

该项目将分析从MeV极光x射线成像和光谱（MAXIS） 2000长时间气球活动中获得的数据。这个气球是从南极洲的麦克默多发射的。它检测到两种类型的高能（相对论性）粒子沉淀，(1)MeV沉淀事件和(2)微爆发。分析将检查这两种不同类型事件的来源和粒子能量机制。通过将观测数据与不同过程模型的观测结果进行比较，将观测数据置于上下文中。在不同过程模型中，粒子被激发，然后分散到损耗锥中，因此它们被观测为沉淀粒子。除了纯科学方面的研究外，该项目还将通过将本科生纳入研究项目来加强教育，达特茅斯学院女性科学项目（WISP）将有助于增强空间科学的多样性。
