The proposers will investigate the origins of high-energy solar energetic particles (SEPs) using data collected from the space-based cosmic-ray detector named the "Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics" or PAMELA. This instrument was successfully launched on a Russian spacecraft by European partners in 2006 and is expected to remain operational until at least the beginning of 2012. PAMELA measures SEPs in the same energy range as the ground level events (GLEs) measured by ground-based neutron monitors, while covering lower energies as well. PAMELA thereby bridges the gap between low energy in situ SEP observations from spacecraft and ground-based observations of GLEs. By addressing the important scientific problem of the origin of SEPs, this project will provide information that will improve space weather forecasts and enhance our ability to predict charged particle radiation doses to satellites, astronauts, and flight crews. This effort will forge international collaborations with the European and Russian designers of the PAMELA instrument, and provide US scientists access to a very unique and extensive data set that has previously been unavailable to the US community. In addition, two PhD students will be recruited at the University of New Hampshire and at New Mexico State University to work on this project.

这些提议者将利用名为“反物质探索和光核天体物理有效载荷”（PAMELA）的天基宇宙射线探测器收集的数据来研究高能太阳高能粒子（sep）的起源。该仪器于2006年由欧洲合作伙伴成功地由一艘俄罗斯航天器发射升空，预计至少在2012年初之前将继续运行。PAMELA测量的sep与地基中子监测器测量的地面水平事件（gle）的能量范围相同，同时也覆盖了较低的能量。因此，PAMELA弥合了航天器低能原位SEP观测与地面GLEs观测之间的差距。通过解决sep起源的重要科学问题，该项目将提供信息，以改进空间天气预报，并提高我们预测带电粒子辐射剂量给卫星、宇航员和机组人员的能力。这一努力将与PAMELA仪器的欧洲和俄罗斯设计师建立国际合作，并为美国科学家提供以前美国社区无法获得的非常独特和广泛的数据集。此外，将在新罕布什尔大学和新墨西哥州立大学招募两名博士生参与该项目。
