Do you dare to believe it? Dongguan , which was once popular in the service industry, actually appeared in the "national artifact" that shocked the world. It even subverted China's entire scientific research system, causing countless scientific researchers around the world to go crazy!
So, what is this super scientific research equipment?
On August 23, 2018, China invested 2.3 billion yuan in the spallation neutron source project, officially put into operation, and this magical tool that has spent countless people on hard work will soon change the entire China's industrial system. It is no exaggeration to say that it can accelerate China's scientific research level for 20 years.
What is the role of China's spalling neutron source, known as the "magic weapon of the country", and why can it enable our country to move towards the world's number one technology power?
When I was in school, the chemistry teacher told us that atomic nucleus includes neutron and protons. As the name suggests, the spalling neutron source is actually a "neutron manufacturing plant". It will use ion source to generate a negative hydrogen particle beam. After stripping, it becomes protons and injects into the substance we need to observe, and a cleavage reaction occurs on the substance target to produce neutrons.
Some people will ask, why can’t we directly observe the nucleus and have to go through such a tedious process? Actually, it's very simple, let's give an example. If you have an invisible face in front of you now, if you want to figure out what he looks like, you need to shine his face. The more beams you shoot, the more accurate his appearance will be.
is unique. If you want to figure out the microstructure of a matter now, then you can use the spalling neutron source to emit a large number of proton beams and record the neutron trajectory after spalling, and you can see what the microstructure of this matter is like. In fact, after all, the spalling neutron source is a "super microscope" that can help us better study the microstructure of things.
Of course, at this time, some enthusiastic netizens will question it. This thing doesn’t sound very useful. Why can it attract more than 100 scientific research teams around the world? Some even bring research centers here just to witness its style with their own eyes?
In fact, netizens who have such ideas are a little confused and shallow. Spallation neutron sources can be said to directly determine the level of scientific and technological development in mankind in the next century. Whether it is high-end technology research and development or basic technology research, spallation neutron sources can provide strong support for them.
is even considered a nightmare cancer by countless families. With the birth of spalling neutron sources, a therapy for using boron neutrons to capture cancer cells has also been derived. The biggest feature of this therapy is that it can save patients with advanced cancer ! We all know that the original methods of treating cancer have a risk of destroying healthy cells in the body.
However, if medical scientists use spalling neutron sources to inject the drug carried by boron neutrons into the human body, they can achieve accurate blows and eliminate cancer cells without any impact on healthy cells in the human body. This can be said to be a disruptive medical treatment technology. If this technology can be applied to clinical treatment, there is no doubt that the average life expectancy of humans will increase by 10 years. Brother Guan also sincerely hopes that one day our country's spalling neutron source technology can completely eliminate this nightmare that has plagued mankind for thousands of years.
Of course, the application of this "country artifact" in medical field is just a drop in the ocean of its magical functions. What is even more shocking is still behind.
Have you ever thought about a question that in China, both aircraft and high-speed rail, it is called the safest transportation tool in the world. But in fact, these transportation tools contain countless invisible and intangible stresses, which affect their service life and travel safety. These stresses are difficult to detect if they rely solely on ordinary testing equipment.
However, in the face of "super microscope", these are not problems. Just inject a neutron beam into any metal you want to test, and it will become a "transparent object" in your eyes and you can see any principle you want to know.Of course, if you want to further understand the properties of metal, then you can place it in various environments such as high temperatures and magnetic fields to observe the changes in its internal microstructure. At the same time, the sparse neutron source has extremely strong penetration power, and it can ignore any material thickness to give information about the interactions.
It can be said that as long as there is the help of the spalling neutron source, the mystery of any matter cannot escape your magical eyes.
In fact, in the past decade, our scientific and technological research has been facing a "bottleneck" situation. Countless scientific researchers can only go far away and yell at the hunchback of others' cutting-edge equipment for research. Nowadays, our country has its own spalling neutron source equipment. Even in the next few years, the reactor , which was built in Europe and the United States in the early years, will be retired one after another, and my country will become the center of international neutron scattering research! It can even help China sprint towards the world's largest science power!
Of course, our country has always adhered to the principle of "community of shared future for mankind" and opened China's spall neutron source equipment to cutting-edge scientists around the world for free. In recent years, we have attracted more than 5,000 scientists to study, completed more than 400 projects, and even published more than 60 papers on the principle of neutron spallation in top journals.
can be said that in the near future, the era of scientific research in China will surely usher in!
