has completed about 700 experimental projects, filling many gaps in my country's scientific research field... Next month, the China Spallation Neutron Source (CSNS) will be in operation for four years. With this With an eye-catching report card, the “Spallation Neutron Source National Major Science and Technology Infrastructure Project” won the 2021 Guangdong Provincial Science and Technology Progress Award Special Prize.
It is reported that CSNS is expected to start the second phase of project construction within this year, and the number of spectrometers will increase to about 20 in the future, covering a wider range of research fields.
The localization rate of equipment exceeds 90%.
CSNS, which is located in Songshan Lake Science City, Dongguan City, has a total investment of approximately 2.3 billion yuan. It is a major scientific and technological infrastructure that is key to the construction of the country's "Twelfth Five-Year Plan". This "China's Most Important Instrument" was jointly built by the Chinese Academy of Sciences and Guangdong Province, making our country the fourth country in the world to have a pulsed spallation neutron source. It has also changed the past when Chinese scientists could only go abroad to disperse neutrons. The history of applying for experimental equipment at the fission neutron source.
settled in Songshan Lake Science City, Dongguan City. Faced with challenges of high technical difficulty and high risks, CSNS scientific researchers overcame difficulties and led independent technological innovation. In order to complete the project construction tasks on time and with high quality, the majority of scientific researchers have given full play to their dedication and have become accustomed to working overtime during holidays. Many people even gave up the opportunity to reunite with their families during the Spring Festival holidays to stick to the front line of project construction and contribute to the project construction. CSNS installations contribute.
Time favors those who work hard, and the starlight does not disappoint those who are on the road. In August 2018, CSNS successfully passed the national acceptance, with the equipment localization rate exceeding 90%. Experts from the acceptance committee commented that all indicators of CSNS met or were better than the approved acceptance indicators, the overall design of the device was advanced, the quality of the development equipment was excellent, the highest neutron efficiency of the target station and the comprehensive performance of the three spectrometers reached the international advanced level. In February 2020, the CSNS target beam power reached the design indicator of 100kW, one and a half years ahead of schedule, and the debugging speed exceeded that of similar foreign devices.
"The spallation neutron source is like a 'super microscope'. It is an ideal probe for studying the microstructure of material materials. It provides a technology for my country's fields of materials science and technology, physics, chemistry and chemical engineering, life sciences, resources and environment, and new energy." "An advanced and powerful scientific research platform." Chen Hesheng, academician of the Chinese Academy of Sciences and chief director of the CSNS project, recalled: "This was a far-sighted decision. The concept of the Guangdong-Hong Kong-Macao Greater Bay Area had not been proposed at that time, but the leadership of the Chinese Academy of Sciences. It is hoped to optimize the layout of China's large scientific facilities and combine the strong strength of the Academy of Sciences in basic research and applied basic research with the strong economic strength of the Pearl River Delta region and the urgent need for science, technology and industrial upgrading. "
CSNS registered user. More than 3,400 people
As Chen Hesheng said, CSNS is the first major scientific and technological infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area. Its completion has provided unprecedented convenience for Hong Kong and Macao scientists to use the spallation neutron source. For example, " super steel " is widely used. Related studies show that if the weight of a car is reduced by 10%, it will save 6%-8% of fuel. The team of Professor Huang Mingxin of the University of Hong Kong used the powder diffractometer of CSNS to discover the microscopic mechanism of "super steel" with high strength and good toughness, providing key data for improving the fracture, toughness and corrosion properties of this steel.
Relying on CSNS-related technologies, cancer treatment in my country has also ushered in technological innovation. In August 2020, the CSNS team successfully developed my country's first accelerator boron neutron capture therapy (BNCT) experimental device with completely independent intellectual property rights, laying a technical foundation for the localization and industrialization of my country's medical BNCT treatment device.
BNCT is currently one of the most advanced cancer treatments in the world. It is a type of radiotherapy that uses heavy ions produced by nuclear reactions between neutrons and boron elements enriched in tumor cells to destroy cancer cells. Compared with traditional radiotherapy methods, BNCT has less side effects in cancer treatment. It only targets cancer cells and does not destroy surrounding cells, which improves the patient's comfort level during treatment.Currently, the team is working with Dongguan Hospital Affiliated to Southern Medical University (Dongguan People's Hospital) to promote clinical trial-related work, and has attracted companies such as Chinese Academy of Sciences Holdings Co., Ltd. to establish a BNCT industrialization company in Songshan Lake, Dongguan.
According to statistics, CSNS has more than 3,400 registered users since it was officially put into operation in August 2018, of which more than 1/4 are users in the Greater Bay Area; focusing on international scientific and technological frontiers and major national needs, it supports domestic and foreign research and industry It has conducted about 700 projects and achieved a number of important results, promoting the construction of a comprehensive national science center in the Guangdong-Hong Kong-Macao Greater Bay Area.
The second phase of the project is expected to start within the year
At the beginning of last month, another good news came from CSNS - the atmospheric neutron radiation spectrometer has achieved a number of major technological breakthroughs and successfully passed acceptance.
According to CSNS, this is the first domestic atmospheric neutron ground simulation acceleration test platform jointly built by the Spallation Neutron Source Science Center and the Fifth Institute of Electronics of the Ministry of Industry and Information Technology. It provides an advanced and powerful atmospheric neutron testing and scientific research platform for the research and development and product manufacturing of high-reliability electronic information systems in fields such as energy and energy. It has completed more than 120 experiments.
Don’t forget your original intention and move forward with determination. It is understood that the second phase of the CSNS project is expected to officially start construction this year. After the completion of the project, the number of spectrometers will increase to about 20, and the accelerator target beam power will be doubled, and key performance such as equipment experimental accuracy and speed will be significantly improved to meet the needs of More user needs at home and abroad.
Chen Hesheng said bluntly: "CSNS continues to achieve scientific research results in Dongguan , which fully demonstrates Guangdong Province's determination and achievements in introducing large-scale scientific equipment and promoting scientific and technological innovation. It has also attracted many domestic first-class scientific research institutions to settle in Guangdong to jointly build a large-scale scientific research institute." Scientific device. "
