New Development of Material Science Using Particle Beams

近年来，利用粒子（中子或带电粒子）束进行材料科学研究十分活跃。在国际科学研究资助金（大学间合作研究）的支持下，京都大学和北京大学的研究小组合作推进了粒子束材料科学的研究，开发了更尖端的技术和新的应用。在整个项目中，京都大学的8名成员访问了北京大学，就研究课题进行了研讨，并讨论了实验方法。另一方面，北京大学的8名委员也被邀请到京都大学，就研究课题进行了研讨，并与京都大学的委员进行了讨论。北京大学的一些成员参加了京都大学的实验。关于中子束的应用，在这两所大学进行的裂变中子的测量和计算进行了比较与erch其他。交换了中子截面测量的实验数据。在京都大学反应堆，KUR讨论了中子医学应用的物理问题。关于重离子束的应用，两所大学的成员讨论了许多研究课题。其中，在粒子加速器的基础上，对团簇离子束的产生和应用、离子束材料表面分析、离子束新功能材料的制备等方面进行了卓有成效的讨论。京都大学的成员们为改善北京大学的实验条件提出了几点意见。经过3年的合作，京都大学和北京大学之间的合作，开发了新的实质性合作研究课题。其中一些将在不久的将来实现。

Recently material science research using particle (neutron or charged particle) beams is quite active. By the support of the Grant-in-Aid for International Scientific Research (University -to-University Cooperative Research) the research groups of Kyoto and Peking Universities cooperatively promoted the research on material science using particle beams and developed more sophisticated technologies and new applications.Throughout this project, 8 Kyoto University Members visited Peking University, presented seminars on research topics, and discussed experimental methods. On the other hand, 8 Peking University Members were invited to Kyoto University, and they also gave seminars on research topics and discussed them with Kyoto University Members. A few Peking University Members joined experiments at Kyoto University.1. Concerning the neutron beam applications, measurement and calculation of fission neutrons performed at both Universities were compared with erch others. The experimental data of neutron cross section measurement were exchangeed. Physical problems on medical application of neutrons were discussed at the Kyoto University Reactor, KUR.2. Concerning the heavy ion beam applications, may research topics were discussed by both University Members. Among them, many fruitful discussions were done beside particle accelerators for production and application of cluster ion beams, material surface analysis with ion beams and new functional material creation using ion beams. Kyoto University Members gave several comments to improve experimental conditions of Peking University.After this cooperative work between Kyoto and Peking Universities for 3 years, new substantial cooperative research subjects are developed. Some of them will be realized in near future.
