Japan-UK collaboration on New Neutron Spectrometer

中子散射是一种在微观尺度上研究凝聚态物质结构和动力学行为的强大而独特的科学工具，涉及从物理到生物到工程和材料科学的各个领域。由日本和英国率先提出的加速器驱动脉冲中子源是下一代中子源的明确选择。日本和英国在中子散射方面的合作是日本高能加速器研究组织(KEK)和英国中央实验室研究理事会(CCLRC)于1996年建立的一项协议的结果，该协议旨在促进日本和英国科学家在脉冲中子散射领域的科学合作和交流。它导致了ISIS设施的地图光谱仪的建造，并使日本科学家能够正式进入ISIS的科学计划。1997年日英合作的科学成就如下。一维位置灵敏探测器组的建设已经开始。该建筑的预算由Monbusho在1997财政年度提供(5600万日元)。在这三年内，将完成MAP的联合建设项目，并将用于合作科学研究。1997年，利用已安装的ISIS光谱仪进行的工作重点包括研究量子梯形系统中的磁激子，二维稀疏海森堡反铁磁系统中的分数子激发等。

Neutron scattering is an exquisitely powerful and unique sicentific tool for sutdies of the structure and dynamical behavior of condensed mater on a microscopic scale, in areas ranging from physics to biology to engineering and material science.Accelerator driven pulsed neutron sources, pioneered by Japan and the UK,are the clear choice for the next generation neutron sources. The Japan-UK Collaboration in Neutron Scattering is a consequence of an Agreement between the Japanese High Energy Accelerator Research Organization (KEK) and the UK's Council for the Central Laboratories of Research Councils (CCLRC) established in 1996 to promote scientific collaboration and interchange between Japanese and UK scientists in the field of pulsed neutron scattering. It has resulted in the construction of the MAPs spectrometer at the ISIS Facility and has given formal access to the scientific program at ISIS for Japanese scientists.The scientific achievements of the Japan-UK Collaboration in the Year of 1997 are as follows. Construction of one-dimensional position-sensitive detector bank was started. Budget for the construction was provided by Monbusho in FY1997 (56,000,000 yen). Within these three years, joint construction project of MAPs will be completed and MAPS will be used for collaborative scientific researches.Highlights of the works with already-installed ISIS spectrometers in 1997 include studies of magnetic excitatins in quantum ladder systems, fracton excitations in two-dimensional diluted Heisenberg antiferromagnetic systems etc.
