Nucleus-Nucleus Interactions and Composition of Ultra-High Energy Cosmic Rays (Physics)

这项为期三年的拨款支持教授的研究 路易斯安那州立大学的John P. Wefel及其合作者 在巴吞鲁日。 该集团是日本的核心部分- 美国乳胶室合作。 它们执行 高能宇宙线能谱的测量 在气球上进行高空实验。 本集团 还将进行高能核的研究， 在加速器上使用乳化技术的相互作用 CERN的实验。 该小组使用实验技术， 具有极高的空间精度。 这些技术 在测量罕见的宇宙射线通量中找到应用， 相互作用和核-核相互作用。 的 实验将产生新的信息， 兴趣，并将继续寻找“夸克胶子 “等离子体”，一种新的物质状态。

This three-year grant supports the research of Professor John P. Wefel and collaborators at Louisiana State University at Baton Rouge. The group is a central part of the Japanese- American emulsion chamber collaboration. They perform measurements of the high energy cosmic ray energy spectra with experiments carried to high altitudes on balloons. The group will also perform research on high energy nucleus-nucleus interactions using emulsion techniques at accelerator experiments at CERN. The group uses experimental techniques which produce measurements with very high spatial accuracy. These techniques find application in measurements of rare cosmic ray fluxes and interactions and nucleus-nucleus interactions. The experiments will yield new information of great astrophysical interest, and will continue the search for the "quark-gluon plasma", a new state of matter.
