Great Country Academician

The question raised by the representative of AMSC superconducting company in the United States made the representatives of the manufacturers who came to the press conference in the venue raise their heads with interest.

The research and development of a new material is not so easy.

Whether it is an artificial SEI film or a high-temperature copper-carbon-silver composite superconducting material, it can be said that it is a hot field in the material industry, and the world has studied it for more than ten years or even decades.

However, more than ten years of research all over the world failed to achieve results, and it was completed in just two or three years in the hands of Professor Xu.

It would be a little too incredible to say that it was pure luck.

One time can be said to be good luck, but if it is said to be lucky twice, I am afraid not many people believe it.

Not many people thought about this before, but after the representative of AMSC superconducting company in the United States raised it, the representatives of these manufacturers quickly figured it out.

Compared with luck, they are more willing to believe that Professor Xu really has a 'magical' mathematical model in his hands.

Although mathematical models have always played an auxiliary role in the process of research and development of traditional materials, with Professor Xu's mathematical and physical abilities, he may be able to find another way in this regard and play a key role. .

Especially before this, at the press conference of the artificial SEI film, a researcher from the German Federal Institute for Materials Research asked questions about the mathematical model at the press conference. If I remember correctly, Professor Xu did not seem to have Denies that he has a model for materials research.

If one really wants to master such a mathematical model, it seems that it is not impossible to research two materials that can disrupt related industries in just two or three years.

If so, that might be the biggest takeaway of the day.

For a while, the commotion and mood swings in the venue became a little violent, and everyone was waiting for the answer from the person on the podium.

On the podium, Xu Chuan glanced at the representative of AMSC Superconducting Company.

This representative is a bit interesting, want to focus on the model in his hand? Or have other ideas?

I don't know if it was the instruction of AMSC Superconducting Company or his own actions.

However, there is a mathematical model in the Chuanhai Materials Research Institute, which is considered an open thing and cannot be hidden.

Of course, he wasn't going to hide it either.

After thinking for a while, Xu Chuan said, "The Chuanhai Materials Research Institute under my name does have a mathematical model for material research, but it doesn't have as much effect as you imagine."

"As for the artificial SEI thin films and high-temperature superconducting materials I have studied, they are all based on this model, and this is even more impossible."

"No one has ever been able to rely on a mathematical model to complete the research and development of a new material. This is impossible. Everyone here is also an expert in the field of materials. I believe everyone should be very clear about the role of mathematical models in materials. "

After the words fell, the representative of AMSC Superconducting Company quickly asked: "Then, has Professor Xu ever thought about making this mathematical model public?"

"For the materials industry, an excellent mathematical model can greatly promote the development of materials science. I believe you will consider it for the development of the materials industry."

Hearing this, Xu Chuan couldn't help but sneered, it was really shameless.

"If AMSC Superconducting Company is willing to disclose all patent authorizations for free, I am also willing to disclose this mathematical model."

"If you can't represent AMSC Superconducting, suggest that AMSC Superconducting get a competent representative. Next."

A press conference would have been perfect if AMSC Superconductor hadn't messed it up.

But for Xu Chuan, this is not a big deal.

The point to pay attention to is the need to strengthen network security and confidentiality in the future.

This wave of AMSC Superconducting Company may attract the attention of many material companies.

It is not impossible for these "capitalists" to steal commercially or buy researchers from Chuanhai Materials Research Institute to obtain material calculation models.

However, the material calculation model is not the same as other things. If the source code and underlying mathematical formulas are leaked, the other party can directly use them.

The press conference on high-temperature copper-carbon-silver composite superconducting materials ended, and Xu Chuan returned to the Chuanhai Materials Research Institute. However, he did not immediately devote himself to work, but took the time to call Edward Witten.

The superconducting materials needed by CERN to upgrade the LHC Large Intensive Particle Collider are a large order, worth at least tens of billions of RMB, and such an order is worth his personal intervention to intercept.

"Hello, Xu Chuan, what can I do for you?" After the call was connected, Wei Teng's voice came from the phone, with a hint of fatigue.

Xu Chuan heard the exhaustion, and asked with concern: "Teacher, what's the matter with you? Hearing the sound, he looks a little tired?"

Wei Teng replied: "It's nothing, the workload on CERN is a bit heavy recently."

"Is CERN still looking for inert neutrinos and dark matter?" Xu Chuan asked quickly.

Edward Witten was silent for a while, nodded and said: "Yes, but there have been no results. Maybe what you said is correct. With the current equipment, it is difficult for us to find traces of dark matter."

After a pause, he continued: "CERN has almost given up, and we are discussing to upgrade the LHC."

Xu Chuan smiled and said, "I called you, mentor, just for this matter."

Witten: "?"

Xu Chuan: "This upgrade of the LHC should use Bi series high-temperature superconducting materials purchased from Sakura Country, right?"

Hearing this, Wei Teng was a little surprised, and asked curiously: "How did you know? I remember that this matter has not been announced yet?"

Xu Chuan smiled and said: "I won't talk about this, I want to ask if CERN is interested in new superconducting materials? I have a normal pressure 152K, a critical magnetic field above 20T, and a critical current at 20T. Will CERN be interested in the new high-temperature superconducting material of 5500A/mm2?"

On the opposite side, Edward Witten stood there with his mouth slightly open, and after a while he came back to his senses, swallowed his air in surprise and asked, "152K, 20T? Are you sure?"

As a theoretical physicist stationed at CERN for many years, he knows the performance of the large strong particle collider all too well.

The superconducting magnets used by the LHC today are made of niobium-titanium (NbTi) superconducting materials. Currently, they can provide a magnetic field strength of 8T. If it is higher, it will cause the niobium-titanium alloy to return to its normal state due to the phenomenon of inverse superconductivity.

The Bi series high-temperature superconducting alloy that CERN is currently planning to purchase from Sakura Country has a critical temperature of 102K and a critical magnetic field of around 13T.

From the data point of view, it has been completely exploded.

Xu Chuan nodded with a smile, and said, "That's right, it is the latest superconducting material developed by the Chuanhai Materials Research Institute under my name. It has passed a complete test and a press conference has been held."

"If you pay attention to the material world, mentor, you should be able to see the relevant news tomorrow at the latest."

Hearing this, Edward Witten immediately remembered the memory he had when he went to Huaguo to invite this student to participate in the CERN dark matter exploration project.

At that time, his student rejected the invitation, saying that he still had research in his hands. Now it seems that it is this high-temperature superconducting material.

It's just that the speed of his research is too fast.

In half a year at most, such a huge achievement has been made in the field of high-temperature superconductivity.

For a high-temperature superconducting material, the superconducting temperature of 152K is actually not critical, because it has crossed the temperature line of 77K for liquid nitrogen.

However, the critical magnetic field strength of 20T and the critical current up to 5500A/mm2 at 20T are too important for high-temperature superconducting materials.

Especially for large strong particle colliders, the higher the critical magnetic field strength, the higher the collision energy level.

The critical magnetic field of 20T is enough to raise the collision energy level to a three-digit level.

This kind of collision energy level should be enough to search for dark matter anyway, right?

After thinking for a while, Witten continued to ask: "I will talk to President Gross first, there will be a related meeting tomorrow, and I will bring it up at the meeting."

After a pause, he then asked: "By the way, I need you to provide a parameter data of the superconducting material. In addition, is this superconducting material energy-producible? If it is just a product in the laboratory, I am afraid it will not be very big." significance."

Xu Chuan nodded with a smile, and said: "The data is fine, I will send it to your mailbox later. As for industrialization, I have already found a method for industrialized mass production, and I am currently looking for a cooperative manufacturer. I believe that at the speed of Huaguo , it will be mass-produced in a short time.”

Witten: "If this is the case, I will communicate with the council. This is a good thing for CERN. You wait for my news, and I will give you feedback."

Xu Chuan smiled and said, "I'm sorry for the mentor."

Here, Xu Chuan is negotiating with his mentor Edward Witten, trying to intercept the high-temperature superconducting material order from CERN and Sakura Country.

On the other side, Academician Gao Hongming and Academician Peng Hongxi have already arrived in Luyang by high-speed rail.

Here is the largest controllable nuclear fusion base in Huaguo, with the Luyang Hyperloop (HT-7), the All-Superconducting Tokamak (EAST), the EAST auxiliary heating system, and the comprehensive research facility for the fusion reactor host key system (CRAFT) ) National major scientific and technological infrastructure in the four major nuclear fusion research fields.

Came to Luyang Science Island again, and after verifying his identity, Peng Hongxi walked into the industrial park. Looking at the almost unfamiliar scene after nearly ten years of development, the old man had a trace of complicated emotions in his eyes.

He has worked here for more than ten years. In 1998, when the Institute of Plasma Physics of the Chinese Academy of Sciences undertook the construction of the national major scientific engineering project "HT-7U Superconducting Tokamak Nuclear Fusion Experimental Device", he was here. Leading the work, it was not until a few years ago that he retired and returned to Mizuki.

Although he has left, he still pays attention to the news here.

After decades of development, the Plasma Research Institute of Luyang Chinese Academy of Sciences has become the most important controllable nuclear fusion research base in Huaguo, and has achieved brilliant and splendid results in the past ten years.

For example, in 2012, the EAST device broke the world record and obtained 20 million degrees Celsius high-parameter divertor plasma for more than 400 seconds; in 2017, it achieved a record-setting 101.2-second steady-state long-pulse high-constraint plasma operation; in 2018 A number of major breakthroughs have been achieved, such as plasma operation at 100 million degrees Celsius.

The achievements one by one made him feel comforted and proud.

Now that he came here again, he couldn't help feeling a little bit emotional.

Just like a child brought up by myself, even though it has gone out independently, seeing it go further on the road of controllable nuclear fusion will also give me a sense of satisfaction and pride.

"Hey, Lao Peng, what wind brought you here?" Academician Chen Mingji, who was working in the research institute building, stood up with a smile to greet Peng Hongxi and Gao Hongming.

The two used to be colleagues, but he was not here before. Later, after Peng Hongxi abdicated, he was transferred from the Southwest Institute of Nuclear Physics to take over the leading work of the Plasma Institute of Luyang Hua Academy of Sciences.

"We haven't seen each other for several years." Peng Hongxi smiled and said with a sigh.

"Yeah, after you left in 2012, you met once at the Academician Conference in 2014. Now five or six years have passed." Chen Mingji smiled after thinking about it.

"Come on, come in and sit down."

In the office, Chen Mingji brewed a pot of tea, and after the three of them exchanged pleasantries for a while, Peng Hongxi said, "Speaking of business, I came here this time to discuss something with you."

Academician Chen Mingji smiled and said, "What's the matter? Is it worth your trip out of the mountain yourself?"

"Last year, I agreed to the invitation of Academician Xu Chuan Xu to help him complete the Jinling Controlled Nuclear Fusion Project. Establish a set of mathematical models for turbulent flow."

Listening to what Peng Hongxi said, although Chen Mingji still had a smile on his face, his eyes had changed a bit.

Of course he knew that his old friend came back to assist the young man in establishing the Jinling Controlled Nuclear Fusion Project. It's just that he didn't take care of it, nor did he ask.

Now that he said this, he probably understood why these two came here.

"After several rounds of supercomputing verification, the parameters of the numerical control model of plasma turbulence are perfect, and time is waiting for no one. For us and the country, the sooner the controllable nuclear fusion project can be completed, the better. So this time, I want to discuss with you about borrowing the EAST device to complete the actual control and calculation of the model."

On the opposite side, Chen Mingji pondered for a while, and said, "Sorry, I'm sorry that I can't agree to your request."

Hearing this, Peng Hongxi showed a little surprise, and quickly said: "This is a great thing. You should know how much the control model of plasma turbulence is helpful for the plasma operation in the reactor chamber."

Chen Mingji shook his head, restrained his smile and said, "It is precisely because I know clearly that I refuse."

"The control model of plasma turbulence is undoubtedly critical to the operation of a controlled nuclear fusion reactor, but the risk of changing the control system is too great for the EAST plant."

"If the plasma in the reactor chamber got out of control, the consequences would be catastrophic for the EAST facility."

"The JT-60SA controllable nuclear fusion experimental reactor of the QST Central Fusion Research Institute in Sakura Country is a lesson from the past. If such a thing happens to the EAST device, you and I will be sinners."

"So I'm sorry I can't agree to your request. The EAST device is everyone's hard work, and I can't take risks with it."

PS: I went home for the Dragon Boat Festival, and I was stuck on the road for a long time. There is only one chapter today. I will see if I can write more tonight and post it tomorrow ().
