Chapter 353 Visit to Luyang Science Island

The question raised by the representative of the US AMSC Superconducting Company made the representatives of the manufacturers who came to attend the press conference raise their heads with interest.

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

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

However, the world has not achieved results after more than ten years of research, but Professor Xu completed it in just two or three years.

If it is really pure luck, it is a bit too incredible.

It can be said to be good luck once, but I am afraid that not many people believe it twice.

Not many people have thought about this aspect before, and after the representative of the US AMSC Superconducting Company proposed it, these manufacturers' representatives 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 traditional material research and development, 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 artificial SEI film, a researcher from the German Federal Institute of Materials asked questions about mathematical models at the press conference. If I remember correctly, Professor Xu did not seem to deny that he had a model for material research.

If you really master such a mathematical model, it seems not impossible to develop two materials that will subvert related industries in just two or three years.

If this is true, then this may be the biggest gain today.

For a while, the commotion and emotional fluctuations in the venue became a little intense, and everyone was waiting for the answer of the person on the podium.

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

This representative is a bit interesting. He wants to focus on the model in his hand? Or does he have other ideas?

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

However, there is a mathematical model in the Chuanhai Materials Research Institute. This is a public thing that cannot be concealed.

Of course, he didn’t plan to hide it.

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 is not as useful as you think."

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

"No one has ever relied 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, Professor Xu, have you 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 sneer. This is really too shameless.

"If AMSC Superconducting is willing to make all patents public for free, I am also willing to make this mathematical model public."

"If you can't represent AMSC Superconducting, I suggest that AMSC Superconducting replace a capable representative. Next."

A press conference would be perfect if AMSC Superconducting didn't mess with it.

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

The point to note is that network security and confidentiality need to be strengthened in the future.

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

It's not impossible for these "capitalists" to steal or bribe researchers from the Chuanhai Materials Research Institute to obtain material calculation models.

And the material calculation model is not quite the same as other things. If the source code and the underlying mathematical formula are leaked, the other party can use it directly.

After the press conference on high-temperature copper-carbon-silver composite superconducting materials, Xu Chuan returned to the Chuanhai Materials Research Institute, but he did not immediately get into work, but took the time to call Edward Witten.

The superconducting materials needed by CERN to upgrade the LHC Large Intense Particle Collider are a large order, worth at least tens of billions of RMB. Such an order is worth his personal interception.

"Hello, Xu Chuan, what do you want to talk to me about?" After the call was connected, Witten's voice came from the phone, with a hint of fatigue.

Xu Chuan heard this trace of fatigue and asked with concern: "Teacher, what's wrong with you? You sound a little tired?"

Witten replied: "Nothing, the workload at CERN has been 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 has been no result. Maybe you are right. With the current equipment, it is difficult for us to find traces of dark matter."

After a pause, he continued: "CERN is almost giving up, and we are discussing upgrading the LHC."

Xu Chuan smiled and said, "I called you, instructor, exactly for this matter."

Witten: "?"

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

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

Xu Chuan smiled and said: "I won't talk about this. I would like to ask CERN if it is interested in new superconducting materials? I have a kind of normal pressure 152K, a critical magnetic field of more than 20T, and a critical current of 20T. Will CERN be interested in new high-temperature superconducting materials with 5500A/mm2?”

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

As a theoretical physicist stationed at CERN all year round, he knows the performance of the Large Strong Particle Collider all too well.

The superconducting magnet used by the LHC today is made of niobium titanium (NbTi) superconducting material. It can currently provide a magnetic field strength of 8T. If it is higher, the inverse superconducting phenomenon will occur, causing the niobium titanium alloy to return to its normal state.

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

Judging from the data, it has been completely destroyed.

Xu Chuan smiled and nodded, saying: "Yes, it is the latest superconducting material developed by the Chuanhai Materials Research Institute under my name. It has been completely tested and a press conference has been held."

"Tutor, if you pay attention to the materials industry, you should be able to see relevant news tomorrow at the latest."

Hearing this, Edward Witten immediately recalled the memory of when he went to China to invite this student to participate in the CERN dark matter exploration project.

At that time, his student declined the invitation, saying that he still had research to do, and now it seems that this is the high-temperature superconducting material.

However, the speed at which he conducted research was a bit too fast.

It took at most half a year to achieve such great results in the field of high-temperature superconductivity.

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

However, the two parameters of the critical magnetic field strength of 20T and the critical current that can reach 5500A/mm2 at 20T are too important for high-temperature superconducting materials.

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

A critical magnetic field of 20T is enough to increase 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 then asked: "I will tell President Gross first. There will be a relevant meeting tomorrow, and I will raise it at the meeting then."

After a pause, he then asked: "By the way, I need you to provide parameter data of a superconducting material. In addition, can this superconducting material be productive? If it is just a product in the laboratory, I'm afraid it won't be much. significance."

Xu Chuan smiled and nodded, and said: "There is no problem with the data. I will send it to your email later. As for industrialization, I have found a method for industrial mass production and am currently looking for cooperative manufacturers. I believe that with China's speed , it won’t be long before it can be mass-produced.”

Witten: "If this is the case, I will go and 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 bothering you, mentor."

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

On the other side, Academicians Gao Hongming and Peng Hongxi have taken the high-speed train to Luyang.

Here is the largest controllable nuclear fusion base in China, with the Luyang Hyperring (HT-7), the all-superconducting tokamak device (EAST), the EAST auxiliary heating system, and the fusion reactor host key system comprehensive research facility (CRAFT). ) is a major national scientific and technological infrastructure in the four major nuclear fusion research fields.

Coming to Luyang Science Island again, 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 hint 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 He took the lead in the work until a few years ago when he retired and returned to Shuimu.

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

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

For example, in 2012, the EAST device broke the world record and obtained a high-parameter divertor plasma of 20 million degrees Celsius for more than 400 seconds; in 2017, it achieved a record of 101.2 seconds of stable long-pulse high-confinement plasma operation; in 2018 A number of major breakthroughs have been achieved, including plasma operation at 100 million degrees Celsius, and so on.

Each achievement brings him comfort and makes him feel proud.

Now that he is here again, he can't help but feel a little nostalgic.

It's like a child he raised himself. Although it has now gone out to explore independently, seeing it go further on the road of controlled nuclear fusion, he will also feel a sense of satisfaction and pride.

"Hey, old Peng, what wind blew you here?" Academician Chen Mingji, who was working in the building of the institute, smiled and stood up to greet Peng Hongxi and Gao Hongming.

The two used to be colleagues, but he was not here before. After Peng Hongxi retired, he was transferred from the Southwest Institute of Nuclear Physics to take over the leading work of the Plasma Institute of Luyang Huake Institute.

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

"Yes, after you left in 2012, we only met once at the Academician Conference in 2014. Now it's been five or six years." Chen Mingji thought for a while and smiled.

"Come, come in and sit down first."

In the office, Chen Mingji brewed a pot of tea. After the three of them exchanged greetings for a while, Peng Hongxi said, "Let's talk business. I came here this time because I want to discuss something with you."

Academician Chen Mingji smiled and said, "What is it? Is it worth your personal trip?"

"Last year, I agreed to the invitation of Academician Xu Chuan to help him complete the Jinling controlled nuclear fusion project. Now the project has started and has entered a critical stage. Academician Xu has established a mathematical model for the plasma turbulence in the chamber of the controlled nuclear fusion reactor."

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

He naturally knew that his old friend had come back to assist the young man in establishing the Jinling controlled nuclear fusion project. It's just that he didn't care about it, nor did he ask about it.

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

"After several rounds of supercomputing verification, the parameters of the numerical control model of plasma turbulence are perfect. In addition, time waits for no one. For us and the country, the sooner the controlled nuclear fusion project is completed, the better. So this time I came here to discuss with you and borrow the EAST device to complete the actual control verification of the model."

Opposite, Chen Mingji pondered for a moment and said, "Sorry, I can't agree to your request."

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

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

"The control model of plasma turbulence The model is undoubtedly crucial to the operation of the controlled nuclear fusion reactor, but changing the control system will be too risky for the EAST device. "

"If the plasma in the reactor chamber gets out of control, the consequences for the EAST device will be catastrophic."

"The JT-60SA controlled nuclear fusion experimental reactor of the QST Fusion Research Institute in Sakura Country is a precedent. 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 the hard work of everyone. I can't take risks with it."

PS: I went home for the Dragon Boat Festival. I was stuck in traffic for most of the day. There is only one chapter today. I'll see if I can write a little more in the evening and post it tomorrow ().
