The construction of the phase II China Spallation Neutron Source (CSNS) project, a "super microscope" for exploring the microstructure of materials, commenced in Dongguan, Guangdong on March 30th.

Since the completion of its first phase in 2018 and subsequent national acceptance, with over 6,000 registered users and more than 1,500 completed research projects, significant scientific and technological innovations have been achieved in key areas such as aerospace components, lithium-ion batteries, rare-earth magnetism, and new high-temperature superconductors.

The construction of the second phase is expected to last for 5 years and 9 months. The number of neutron spectrometers will increase to 20, and the design target for accelerator beam power will rise from 100 kW to 500 kW. This advancement will not only shorten experimental time effectively but also enhance experimental resolution, enabling the measurement of smaller samples and capturing faster motion processes.

国产“超级显微镜”上新！中国散裂中子源二期工程在东莞启动建设

探索物质材料微观结构的“超级显微镜”中国散裂中子源二期工程3月30日在广东东莞启动建设。

一期工程自2018年完成国家验收、投入运行以来，注册用户已超6000人，完成课题1500多项，在航空航天关键部件、锂离子电池、稀土磁性、新型高温超导等重点领域取得了一批科技创新成果。

二期工程建设周期预计5年9个月，中子谱仪数量将增加到20台，加速器打靶束流功率的设计指标将从100千瓦提高到500千瓦，不仅能够有效缩短实验时间，还能使实验分辨率更高，测量更小的样品，捕捉更快的运动过程。
