The goal of this project is to improve our understanding of Solar Energetic Particle (SEP) events. An SEP event is a situation in which the sun produces a stream of highly energetic particles with velocities approaching the speed of light. SEP events are severe space weather phenomena that can be physically harmful to astronauts in space and have the potential to damage satellites. They also lead to increased ionization in Earth's upper atmosphere and can lead to communications problems and can affect GPS location services. This project will analyze a comprehensive set of SEP measurements to improve our understanding of the mechanisms that produce SEP events. By combining data from several sources, the project will generate a baseline for modeling these events. The project will also include educational activities geared toward K-12 students and in particular will include outreach to young women and under-represented minorities.The primary source of data for this project will be the Alpha Magnetic Spectrometer (AMS-02) that was installed on the International Space Station in 2011. The AMS-02 instrument will provide unprecedented measurements of solar protons and helium in the highest energy range of solar particles. Coupling the AMS-02 data with data from other instruments such as neutron monitors will make it possible to generate complete particle spectrograms from a few hundred MeV to almost 1 TeV. Analysis of the spectrograms of protons and He++ ions will make it possible to determine the roles that different acceleration mechanisms play in producing these high energy particles. The researchers will generate a database of SEP events that will be made available to the entire space physics community. They will also generate educational tools including online tools that can be used for public outreach. These tools will become a part of the Quarknet education and outreach program that is funded by NSF and DOE.

该项目的目的是提高我们对太阳能粒子（SEP）事件的理解。 SEP事件是一种情况，在这种情况下，太阳产生了高能颗粒的流，速度接近光速。 SEP事件是严重的太空天气现象，可能对太空中的宇航员身体有害，并有可能损坏卫星。它们还导致地球上层大气层的电离增加，并可能导致通信问题，并可能影响GPS的位置服务。该项目将分析一组全面的SEP测量值，以提高我们对产生SEP事件的机制的理解。通过结合来自多个来源的数据，该项目将生成用于建模这些事件的基线。该项目还将包括针对K-12学生的教育活动，特别是将包括向年轻妇女和代表性不足的少数群体进行宣传。该项目的主要数据来源将是在2011年在国际空间站上安装的Alpha磁性光谱仪（AMS-02）。AMS-02仪器将为Solar Protons and Helium提供固定量的固定量和固l量的最高级别。将AMS-02数据与来自其他仪器（例如中子监视器）的数据耦合，将使从几百MEV到几乎1 TEV生成完整的粒子谱图。对质子和HE ++离子的光谱图的分析将使确定不同加速机制在产生这些高能量颗粒中起着作用的作用。研究人员将生成一个SEP事件的数据库，该数据库将提供给整个太空物理社区。他们还将生成教育工具，包括可用于公共外展的在线工具。这些工具将成为由NSF和DOE资助的Quarknet教育和外展计划的一部分。
