中国散裂中子源的多学科应用

Applications of the China Spallation Neutron Source

中国散裂中子源(China Spallation Neutron Source,CSNS)是我国首台、世界第4台脉冲型中子大科学设施。CSNS基于加速器产生的高能质子轰击钨靶产生中子,然后利用中子进行实验。CSNS面向全世界的用户开放,为科学研究和工业研发服务,在物理、化学、生物、能源、材料等领域都有广泛的应用。文章将介绍CSNS的基本构成、发展历程和中子散射的多学科应用。

The China Spallation Neutron Source(CSNS) is the first such source in China,and the fourth in the world. As an accelerator-based neutron source, CSNS provides intense neutron beams for scientific research and industrial development. The large facility can host hundreds of researchers from university, national labs and industries in physics, chemistry, biology,energy, and material science from all over the world. In this paper we describe the basic principles, historic development, and applications of CSNS.
