Engineering progress of the China Spallation Neutron Source project

Here's what it does:Introduction: The role is to observe.

Tong Xin, chief scientist of the National Key R&D Program, gave a vivid analogy: the Spallation Neutron Source is like a "super microscope", which can "see" through the microstructure of materials without causing damage to matter. One of the most direct applications is that it can detect the "internal injury" of materials, which is of great significance to materials science research.

Before Songshan Lake, three pulsed spallation neutron source devices had been built around the world.

Significance of the Spallation Neutron Source:Now China has completed the construction of four spallation neutron source mass spectrometers, and these cutting-edge scientific instruments can not only allow China to discover more secrets about biology or materials science, but also can be used to promote genetic changes and induce benign mutations in plants, not to mention that the mass spectrometer can also detect flaws of some key precision parts and escort China's aerospace and other cutting-edge technology industries.

It is no wonder that when foreigners heard that the number of spallation neutron mass spectrometers in China's hands had increased again, they thought that such equipment was not for military use, but that it would bring great contributions to China's future development and progress.

Summary. The China Spallation Neutron Source is a state-owned enterprise. Specifically, the Spallation Neutron Source is led by the Chinese Academy of Sciences and belongs to the national major scientific research infrastructure.

In terms of operation and management, the China Institute of Atomic Energy (Dalian Institute of Chemical Physics, Chinese Academy of Sciences) is responsible.

The China Spallation Neutron Source is a state-owned enterprise. Specifically, the Spallation Neutron Source is led by the Chinese Academy of Sciences and belongs to the national major Huaiyin scientific research infrastructure. In terms of operation, paddle wheel and management, the China Institute of Atomic Energy (Dalian Institute of Chemical Physics, China Academy of Science and Technology) is in charge.

The China Spallation Neutron Source is one of the major scientific and technological equipment independently developed by China, and its construction aims to provide high-quality neutron beam services for scientific research, engineering technology and industrial innovation. In the process of building the Spallation Neutron Source, many scientific research institutions, universities and enterprises were involved, and it was strongly supported by the state. At present, the Spallation Neutron Source has become an important scientific research platform in China's materials science, life science, energy and environment and other fields, and has made many important achievements and progress.

At the same time, the Spallation Neutron Source also actively participates in the international cooperation of Spallation Ridge, strengthens exchanges and cooperation with other countries in the field of scientific research, and promotes the development of China's science and technology and the enhancement of its international influence.

When a medium-energy proton hits the heavy nucleus (tungsten, mercury and other elements), it will cause the instability of the heavy nucleus and "evaporate" 20-30 neutrons, so that the heavy nucleus "splits" and "emits" a considerable number of neutrons in all directions, which greatly improves the efficiency of neutron production, and the device that works according to this principle is called the spallation neutron source.

The China Spallation Neutron Source (CSNS), the largest single national scientific and technological infrastructure in China to date, will be accepted in 2018, and the first batch of experiments for the three spectrometers of the device will be announced, covering several cutting-edge interdisciplinary and high-tech research and development fields.

The study foundBefore the discovery of neutrons, people did not fully understand the internal structure of atomic nuclei, but after the discovery of neutrons, people learned that atomic nuclei are composed of neutrons and protons. Therefore, the discovery of neutrons is a turning point for understanding the internal structure of atomic nuclei, which is of great theoretical significance, and also opens the way for the utilization of atomic energy.

Summary. Hello, the China Spallation Neutron Source is led by the China Institute of Atomic Energy (hereinafter referred to as the "Chinese Academy of Sciences"), which is a national comprehensive research institution in China and directly belongs to the Chinese Academy of Sciences. Therefore, it can be said that the China Spallation Neutron Source is a state-led project, not a state-owned enterprise.

The Chinese Academy of Sciences (CAS) was established in 1949 as China's national comprehensive research institute. Its main task is to carry out basic and cutting-edge research in the fields of natural sciences, technological sciences, and high and new technologies, and to provide scientific and technological support for the country's economic construction and national defense construction. The Chinese Academy of Sciences has a number of research institutes and laboratories, including the China Academy of Engineering Physics, which belongs to the China Spallation Neutron Source.

The China Spallation Neutron Source is an important project of the Chinese Academy of Sciences, and its main purpose is to meet the needs of the country's research in the fields of new materials, new energy, and life sciences.
