UK Japan Collaboration on Intense Pulsed Neutron Scattering Experiments

本类主要是为推进第二次英日中子散射研究合作计划（以下简称英日合作计划）派遣研究人员到英国进行计划和管理。本计划的预算用于特定的研究领域（1）：局域自旋原子结构及其动力学的研究（1999 fy-2003 fy，代表：新井雅敏，课题编号11211101）。英国-日本合作计划将在英国卢瑟福阿普尔顿研究实验室的ISIS设施中使用最强（目前世界上最强）的脉冲中子源进行中子散射实验。ISIS的中子强度约为日本KENS（高能加速器研究机构材料结构科学研究所中子科学实验室）中子源的50倍。该项目通过高精度的中子散射实验，创造了国内无法做到的优秀研究成果，同时支持了KENS研究的进展。本研究组支持了ISIS的MARS光谱仪的设计、建造和安装，在其正常运行后，它将作为本合作计划的主要仪器，对于MARS未覆盖的测量区域，ISIS的其他现有仪器也可以使用。根据这一基本研究计划，日本研究人员已被派往英国，从微观角度阐明材料的功能和性质。在中子散射实验中，对能量动量空间中广泛分布的动力学结构因子进行了适当的测量。在该计划下，已经进行了58项实验，发表了45篇研究论文。

The purpose of this category was the mainly planning and managing for the dispatch of researcher to England to push forward the second UK-Japan Neutron Scattering Research Collaboration Program (hereinafter called UK Japan Collaboration Program). The budget of this program was applied to the particular field of research (1): The study of local spin-atomic structure and its dynamics (1999fy-2003fy, Representative : Masatoshi Arai, Subject No.11211101). UK-Japan Collaboration Program is to perform the neutron scattering experiment using the most intense (now in the world) pulsed neutron source in the ISIS facility of Rutherford Appleton Research Laboratory in England. The neutron intensity of ISIS is about 50 times high to the neutron source of KENS (Neutron Science Laboratory, Institute of Materials Structure Science, High Energy Accelerator Research Organization) in Japan. This program has created the excellent research results by highly accurate neutron scattering experiments which are impossible to do domestically and at the same time, it has supported the progress of research in KENS. This study group have supported the design, construction and installation of MARS spectrometer in ISIS and after start of its normal operation, it will be served as a main instrument in this Collaboration Program and for the measuring region uncovered by MARS, other existent instruments in ISIS can also be utilized. In accordance with this fundamental study program, Japanese researchers have been dispatched to England to clarify the functions and properties of the material on the microscopic viewpoint. This task has been performed by the appropriate measurement in the neutron scattering experiment for the dynamical structure factor which is widely distributed in the energy-momentum space. Under this program 58 experiments have been carried out and 45 research papers have been published.
