Editor's Note:
2021 is the first year of the comprehensive national science center in the Greater Bay Area (Songshan Lake Science City) to fully launch the construction, and it is also the 20th anniversary of the establishment of Songshan Lake. At this critical juncture, "20 Years of Leaping Over Songshan Lake" comprehensively sorts out the development process of Songshan Lake in the past 20 years, shows the vivid practice of Songshan Lake's new development concept, and strives to provide a "Songshan Lake sample" for the future development of Dongguan and even the self-reliance and self-reliance of China's scientific and technological innovation.
It is reported that through extensive collection of historical materials, the film crew searched for a group of pioneers, scientists, entrepreneurs, witnesses and witnesses of history who have struggled in Songshan Lake for twenty years, combed the historical context and effective experience of the development of Songshan Lake from their mouths, and decoded the advanced road of Songshan Lake from "garden" to "city".

National Heavy Equipment: The large scientific installation group of Songshan Lake Science City
China Spallation Neutron Source is the fourth in the world, the first pulsed spallation neutron source in China, and the first large scientific device built by China in South China. It is completed and put into use, providing a large-scale scientific research platform with advanced technology, powerful functions and multidisciplinary applications for China's physics, chemistry, life sciences, nanoscience and new energy development.
Looking at the whole country, large scientific installations are either built in municipalities such as Beijing and Shanghai, or in provincial capitals such as Hefei. Why could Such a national heavy weapon as the Chinese spallation neutron source settle in the prefecture-level city of Dongguan, and why could it settle in Songshan Lake, which was not well known at that time? There is contingency behind it, but it is more of a historical necessity.
Fast forward to February 2006, at a seminar held by the Guangdong Provincial Development and Reform Commission, Chen Hesheng, an academician of the Chinese Academy of Sciences, particle physicist, and later the commander-in-chief of China's spallation neutron source project, mentioned that China's spallation neutron source was looking for a suitable construction site. The speaker was unintentional, the listener was intentional, and the relevant person in charge of the Guangdong Provincial Development and Reform Commission immediately reported to the main leaders of Guangdong Province at the time, hoping to strive to bring the China Spallation Neutron Source Project to Guangdong.
In March of that year, the main leaders of Guangdong Province and the Chinese Academy of Sciences believed that the source of Chinese spallation neutrons could be settled in the Pearl River Delta after in-depth docking. Two months later, the team of the Chinese Academy of Sciences went to three places in the Pearl River Delta recommended by the Guangdong Provincial Development and Reform Commission to conduct field investigations, and finally chose Dongguan.
On the one hand, the Chinese Academy of Sciences hopes to combine the strong strength in basic scientific research, applied basic research and high-tech research and development with the strong economic strength of the Pearl River Delta region to promote the southern provinces to carry out basic science and applied scientific research on large scientific devices, improve the level of technological research and development, and promote economic transformation; on the other hand, Dongguan's thick economic and industrial foundation, the city's desire for transformation and upgrading, and scientific and technological innovation have also become the main reasons why Dongguan stands out among many competitive cities.
In fact, Dongguan, which started with "three to one supplement", has long realized the importance of scientific and technological elements. However, compared with beijing, Shanghai and other first-tier cities with many colleges and universities, Dongguan's scientific research resource base is scarce, and there are natural shortcomings in scientific and technological innovation. This requires that Dongguan must use extraordinary means to promote the introduction, agglomeration and transformation of scientific and technological resources. This endogenous sense of urgency for scientific and technological innovation eventually ushered in the landing of China's spallation neutron source.
From the approval of the National Development and Reform Commission in September 2008, to the foundation laying of the project in October 2011, to the success of the first target shooting in August 2017, until the national acceptance in August 2018, after ten years of tempering, a national heavy instrument was born in Songshan Lake. The project construction involves a large number of advanced technologies, overcomes many technical problems, and the localization rate of equipment exceeds 90%. The experts of the acceptance committee evaluated that the indicators of China's spallation neutron source have reached or exceeded the approved acceptance indicators, the overall design of the device is advanced, the quality of the development equipment is excellent, and the maximum neutron efficiency of the target station and the comprehensive performance of the 3 spectrometers have reached the international advanced level.
With the settlement of the China Spallation Neutron Source Project in Songshan Lake, the scientific research team of the Chinese Academy of Sciences has also lived in Songshan Lake for more than ten years. They have witnessed the changes in Songshan Lake, witnessing the environment of Songshan Lake getting better and better, and its popularity is getting stronger and stronger. Songshan Lake has become their second hometown. Chen Yanwei, deputy director of the Institute of High Energy of the Chinese Academy of Sciences and director of the Dongguan Research Department, was one of the earliest participants in the project.

According to Chen Yanwei's recollection, the location of the source of the spalled neutron was still a lychee forest full of mountains, and in the past ten years, the original lonely and unknown town has become a hot land for innovation that attracts global attention. "Thanks to Songshan Lake for its strong support to us, including education, transportation, environment, service and other aspects, it has provided us with a lot of convenience."
Science and technology are established by the nation, and strong science and technology are strong in the country. How to achieve a high level of scientific and technological self-reliance and self-improvement? The first is to "strengthen originality and leading scientific and technological research, and resolutely win the key core technology battle". China Spallation Neutron Source injects surging power into the innovation drive of the pilot launch area of the comprehensive national science center in the Greater Bay Area, provides a steady stream of "living water source" for the development of national science and technology, and also attracts more and more world-class scientists to gather in Dongguan.
Feng Ji, general secretary and deputy director of the Songshan Lake Materials Laboratory, who had participated in the site selection process of China's spallation neutron source, said that Lu Yongxiang, president of the Chinese Academy of Sciences at that time, had a special opinion that the landing of China's spallation neutron source should take into account the layout of the national large scientific device, the development of Guangdong, Hong Kong and Macao, and even the long-term problems such as radiation to Southeast Asia.
This is a new normal in Songshan Lake Science City since the official operation of China's spallation neutron source - the world's top scientists have come to Dongguan to rely on large scientific devices to conduct research on cutting-edge topics. Chen Yanwei introduced that as of now, there are more than 2600 registered users of spallation neutron source, and more than 600 projects from many colleges and universities, research institutes and enterprises around the world have been completed, covering many application fields such as new hydrogen storage materials, lithium-ion batteries, new superconducting materials, high-strength steel, solar cell thin films, etc., and have achieved important results.

In the competition of science and technology in today's world, the original innovation and breakthrough from "0" to "1" has become an important part of international competition, which puts forward higher requirements for scientific and technological infrastructure. In addition to the second phase of China's spallation neutron source project, Songshan Lake is actively planning to lay out a number of new large scientific devices such as advanced atassecond laser facilities.
The advanced atassecond laser facility is a light source device based on the interaction of high-power femtosecond lasers with matter to produce atassecond lasers and high-energy photons, which will provide new research methods for physics, chemistry, materials and biomedicine, promote breakthroughs in basic theories in these fields, and trigger a new round of technological revolution.
The successive drops of large-scale heavy equipment mark the acceleration of songshan lake science city from a single large scientific device to a large scientific device cluster, which will drive more high-end innovation elements to gather in songshan lake science city. In July this year, the "Dongguan Songshan Lake to promote source innovation implementation measures" was introduced.
According to the policy, in terms of source innovation, Songshan Lake will arrange 15 million yuan per year, relying on the "Guangdong-Guanguan Joint Fund", the three-level linkage of provinces and municipalities to support basic and applied basic research; arrange 5 million yuan per year, set up an open project for large scientific devices, carry out multidisciplinary interdisciplinary research and application, and develop technologies related to large scientific devices and experimental methods.
Relying on large scientific devices, Songshan Lake is planning to undertake broader basic research, applied basic research and high-tech industrialization, and strives to build itself into the core of the Pearl River Delta large-scale device cluster, the source of national scientific and technological innovation and the joint innovation, open innovation and integrated innovation center of the Guangzhou-Shenzhen Science and Technology Innovation Corridor.
