Research Planning Visits for Cooperative Study of Cosmic Rays

9618451克罗宁该奖项支持计划访问，为芝加哥大学吉姆·克罗宁组织的研究最高能量宇宙射线的全球努力做准备。长期计划包括合作建设两个宇宙射线观测站，这两个观测站将配备研究最高能量的宇宙线，以了解质子或原子核是如何加速到如此高的能量的，并试图确定这些宇宙射线的来源。这项工作有望解决天体物理学的核心问题之一--宇宙射线的起源。与俄罗斯、日本和越南科学家的合作将在这笔赠款下进行。对该项目至关重要的探测器的测试将在日本进行，芝加哥大学的两名学生将参与其中。芝加哥和越南达拉特之间的互访将有助于启动探测器计算机模拟方面的合作。一位重要的俄罗斯科学家访问芝加哥将有助于确定俄罗斯为该项目提供廉价光电倍增管的潜力。

9618451 Cronin This award supports planning visits to prepare for a worldwide effort organized by Jim Cronin, University of Chicago, to study the highest energy cosmic rays. Plans in the long run include collaboration in building two cosmic ray observatories that will be equipped to study the highest energy cosmic rays in order to understand how protons or nuclei are accelerated to such high energies, and to try to determine the sources of those cosmic rays. This work is expected to address one of the central problems in astrophysics, the origin of cosmic rays. Collaboration with Russian, Japanese and Vietnamese scientists will take place under this grant. Testing of detectors essential to the project will take place in Japan, with the participation of two University of Chicago students. Exchanges of visits between Chicago and Dalat, Vietnam will help initiate cooperation on computer simulation of the detectors. A visit to Chicago by a key Russian scientist will help define the potential for Russian contribution of inexpensive photomultipliers to the project.
