Great Country Academician

It is very difficult to solve the problem of multi-orbital correlation effect and superconductivity in the strongly correlated electron system.

Of course, Xu Chuan never thought that this problem could be solved in a short time.

But at least, he already has some clues about the strong diamagnetic mechanism found on the KL-66 material.

I have to say that the two old gentlemen stood at different angles and gave him quite a lot of inspiration.

Whether it is Mr. Yang’s starting from the electron dynamics behavior of a strongly correlated system in a non-equilibrium state, or Mr. Qiu’s view of free electrons in a strongly correlated state as an electronic liquid or an electronic solid mode, it is based on theoretically feasible points. brought up.

The former is suitable for KL-66 material, while the latter may spread to the whole strongly correlated electron system.

So after communicating with the two old gentlemen, he locked himself in the room of the Beihai Hotel and studied it with great concentration.

The days passed day by day like this, and in the blink of an eye, New Year's Day had passed, and it was time for the meeting held by the science and technology group to lead the construction of the large-scale strong particle collider.

Reminded by Zheng Hai, Xu Chuan came to Fuxing Road.

The headquarters building of the science and technology department is here, and the meeting will also be held here.

Compared with the manned spaceflight and moon landing project exchange meeting held last week, this meeting is just a small meeting that cannot be smaller in terms of scale.

However, in terms of the importance of the participants and the financial planning of the project, it is not weaker than the former at all, or even better.

After all, the total cost of the manned spaceflight and moon landing project is only tens of billions even after the increase.

As for the construction of the large-scale strong particle collider, the budget in the early years was almost 200 billion.

Of course, the technology related to the collider has been relatively mature, including superconducting materials, detectors, etc., and the demand for funds has been greatly reduced, because the construction budget will also be reduced a lot.

However, even if the technology is mature and the budget is reduced, it is still a large project of more than 100 billion yuan.

The one-time allocation of funds is much more than that of manned spaceflight.

No way, this kind of basic large-scale scientific research equipment, no matter what it is, costs a lot of money.

For example, the International Space Station, which is the largest space facility for humans in low-Earth orbit, is a joint research and development project of 16 countries including the United States, Tsarist Russia, and the European Space Agency.

The initial construction cost of this project has reached a full 160 billion meters of gold, which is still 160 billion meters of gold 20 years ago.

Or the "Future Circular Collider" (FCC), which was originally planned and built in Europe and has basically been stranded, is expected to cost about 21 billion euros.

It can be seen that most of this kind of basic scientific research equipment is jointly developed by dozens of countries, except for a very small number of top powers that are capable of completing it themselves.

The meeting was held in the headquarters building of the science and technology department, and there were not many people.

When Xu Chuan walked into the building, staff immediately stepped forward, verified his identity, and led him all the way into the conference hall.

In the conference hall, many people have already arrived.

After seeing Xu Chuan, they all stepped forward to greet and communicate with him.

In today's meeting, this is the real boss, and his ideas can almost determine the fate of the future collider.

Xu Chuan smiled and greeted these scholars and government officials one by one, found his seat and sat down.

This meeting, of course, was presided over by Qin Anguo, the leader of science and technology.

According to the meeting procedure, the Chief Qin made a brief report on the whole meeting first, but then said: "This meeting is actually mainly about discussing some things in the process of building and using the large-scale strong particle collider. and questions."

"The specific situation is in the information in front of you, and I have sent it to you before. Please read it again, and then we will discuss and exchange. You can express your ideas. The country needs your ideas and help."

Hearing this, everyone in the conference hall lowered their heads and began to read.

Whether to build a large strong particle collider is beyond the scope of this meeting.

Under Xu Chuan's suggestion, the construction of a large-scale strong particle collider has become a foregone conclusion.

Today's discussion is about how to build, scale, budget, whether it needs to be imported from other countries, technology and other aspects.

Of course, for some of the questions and content exchanged today, basically everyone already has their own answers in their hearts.

After waiting for a while, Qin Anguo continued: "If there are no other questions, let's start officially. Regarding the arrangement of materials in front of you, if you have ideas and suggestions, you can raise your hands to discuss."

Hearing this, someone in the conference hall immediately raised their hands.

"I have an idea about the construction of a large strong particle collider."

Qin Anguo looked over, and the one who raised his hand was the director representative of Hua Guo at CERN, Director Tai Xuewen.

After Huaguo became a member of CERN a few years ago, Director Tai has been in charge of the communication between Huaguo and CERN.

"Director Tai, please tell me." Qin Anguo nodded, motioning for the other party to continue.

Tai Xuewen cleared his throat, and continued: "As for the construction of the large-scale strong particle collider, I think we can learn from CERN's model and expand it into an international cooperation project."

"On the one hand, through multinational cooperation, we can save a lot of money we need to pay. After all, according to the preliminary plan, the budget of 150 billion is not a small number."

"If we can introduce funds from other countries, we can greatly reduce our own expenditure."

"On the other hand, through multinational cooperation, we can absorb excellent materials, equipment, technology, talents, etc. from other countries in large-scale strong particle colliders."

"Especially CERN, in this regard, CERN's experience can be learned, whether it is the construction of the collider or scholars in the field of basic physics, the introduction of these will be of great help to our construction of the collider."

Hearing this, discussions immediately started in the conference hall, and many people nodded in approval, thinking that this method is feasible.

"I think this proposal is feasible. Whether it is budget or technology, if we adopt cooperation, it will indeed reduce a lot of pressure. CERN has perfect collider construction experience. If it is introduced, it will indeed help us save a lot of time. .”

"It is feasible, but how does this ensure our country's control over the collider? You must know that every time CERN starts a research project on the collider, there are endless debates."

"Membership can be adopted. We really need the research and technology of other countries on the collider. It is enough to use the membership system to ensure the proportion of our own scientific research projects."

"I don't think it's appropriate. We have already reserved the technology for building the collider. The help from other countries is not very big. There is also a risk of losing control of the collider. If we want to do it, it is better Let's do it ourselves, and the budget of 150 billion is not unaffordable for us now."

In the conference hall, some were in favor and some were against.

This kind of problem involves many aspects, and it is impossible for everyone to stand on one side.

Suddenly, sitting opposite Xu Chuan, Mr. Yang Zhenxi looked at Xu Chuan, and directly brought the topic to him: "I don't know how Academician Xu thinks about this issue?"

Hearing this, the conference hall immediately fell silent, and everyone looked over.

Stared at by other people, Xu Chuan coughed lightly, and said: "As for whether it is necessary to introduce technology from CERN or other countries, I think it is still necessary."

Hearing this, Mr. Yang looked at him with some surprise. Based on his understanding, he should object.

Xu Chuan didn't care about other people's gazes, and continued: "Although we already have the corresponding technology for the construction of the large-scale strong particle collider, it is undeniable that CERN has spent more time researching on this aspect than we have. It is much longer, and the related technology of the reserve is also more perfect.”

"So the introduction of CERN is necessary."

After a slight pause, he continued: "But I think it is quite necessary for us to have control over the collider that we funded and built."

"The purpose of building a collider is to explore physics on the one hand, and to cultivate physics talents for ourselves on the other hand."

"If the control is lost, subject to other people, some basic things need to be discussed and discussed, it will not make sense for us."

"So the built collider, no matter how we control it, must be in our own hands."

Hearing this, Director Tai Xuewen frowned slightly and asked, "If this is the case, how should we introduce the collider technology from CERN and other countries?"

Xu Chuan smiled and said, "It's very simple."

"My suggestion is that the funds for the construction of the collider should be completed by ourselves alone, but we can communicate with CERN and other countries. If they are willing to provide technical and human support for us in the process of building the collider, then When the collider is complete, we can reserve a member state seat for them."

"Just like our current status of joining CERN, we provide corresponding scientific research funds every year, and obtain corresponding jobs, research tasks, technological achievements and other things."

"In this case, if someone is causing trouble, we can easily kick them out."

"Of course, under normal circumstances, I believe we would not do such a thing. After all, basic scientific research is something that is beneficial to the whole world, and we are not some robbers."

Hearing this, Director Tai Xuewen frowned and asked, "What if they don't agree with this method?"

Xu Chuan said calmly, "Then we don't want them."

"According to the plan, the super large hadron collider we built this time is built on the basis of the petaelectronvolt level, or even higher petaelectronvolt level."

"This will be the world's first large-scale collider at the exascale electron volt level. The demand for the collider is not only our own, but also the European Union and other countries."

"The current situation is that although we need technical support from CERN, we don't necessarily need it completely. And the collision experiment is needed by all countries."

"The current situation is that we give them a chance, rather than begging them to join in, let alone give up control of the collider and turn it into a conference system."

"If they don't think it's going to work, let them build it themselves."

Hearing this, old Mr. Yang, who was sitting opposite Xu Chuan, showed a trace of interest in his cloudy eyes. This is the character of this young scholar. In some places, he is quite domineering.

On the opposite side, Director Tai Xuewen frowned and said: "If CERN and other countries choose to refuse, we may be extremely short of manpower for the experiment after the collider is completed."

"After all, it is impossible for us alone to support such a large-scale basic scientific research project as the research of the collider, and in terms of future expenditures and other aspects, the pressure is extremely high."

Although there are many physicists in Huaguo, it is impossible to devote all of them to the large-scale strong particle collider.

After all, there are many other fields to develop.

The mission of basic scientific research equipment such as colliders is to advance human understanding of the natural world and provide basic scientific knowledge for solving real-world problems.

This type is difficult to rely on the strength of a country.

It is beneficial to all mankind, but it is a great burden to the country that builds and uses it.

Not to mention the huge amount of money spent on construction, just every start-up, maintenance, etc., requires a huge amount of money.

More importantly, its achievements are difficult to transform into applied technology and benefits in a short period of time.

Just like the verification of the Higgs particle and the study of the Standard Model, this theoretical achievement only complements human understanding of the universe and the physical world

In fact, we don't know how many years have passed since the promotion of technological development.

Hearing this question, Xu Chuan smiled and said, "There will be no shortage of people."

"Even if the United States, the European Union and other countries refuse to join us, they have no ability to prevent physicists from coming to us to do research. Unless they can provide a collider with the same strength as ours."

"But for the United States and the European Union, it can be said to be a very difficult thing."

"First of all, they are too busy investing in research on controllable nuclear fusion, so it is difficult to allocate scientific research funds to invest in the field of colliders."

"After all, in addition to the huge amount of money needed to build a large-scale strong particle collider, a large budget is required to start the collision experiment every year."

"The current budget of CERN alone has caused dissatisfaction among many member states. If you ask them to invest a lot of money in it, IMHO, it is almost impossible."

After a pause, he continued: "Secondly, even if the worst happens, the United States and the European Union will continue to invest in this field. The collider they built will hardly surpass us in terms of energy level."

"Don't forget that the core of the collider lies in superconducting materials and detectors."

"The ability of the critical magnetic field of the superconducting material to confine the particles determines the strength of the collision energy level. In this regard, the high-temperature copper-carbon-silver composite superconducting material I have developed has the highest critical magnetic field of the current superconductor."

"Lacking top-level superconducting materials, it is difficult for them to compete with us in the collision energy level. I believe that CERN's cancellation of the order for high-temperature copper-carbon-silver superconducting materials under the pressure of the United States is their biggest regret. .”

"And scientists are realistic. If we welcome and accept other scientists, there will be no shortage of personnel."

"As for the cost, it is undeniable that every start-up of the collider consumes a lot of power, which is why it costs a lot of money every time it is started."

"But don't forget, for us, electric energy is the most indispensable thing in the future. A small-scale controllable nuclear fusion reactor is enough to provide energy for a large collider."

"Except for electricity, other aspects can account for half of the expenditure at most."

As he spoke, he looked at Director Tai Xuewen, and continued, "Finally, and more importantly, I am here!"

"I can say that, except for me, no one will find a particle that is really beyond the standard model within ten years."
