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

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

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

However, the world's research has not been fruitful for more than ten years, and it was completed in just two or three years in the hands of Professor Xu.

If it's pure luck, it's a bit too incredible.

One time it can be said to be lucky, but both times it is said to be lucky, I'm afraid not many people believe it.

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

Rather than luck, they prefer to believe that Professor Xu really has a 'magical' mathematical model in his hands.

Although mathematical models have always played a supporting role in the 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.

In particular, at the press conference on artificial SEI films, some researchers from the German Federal Institute for Materials Research asked questions about mathematical models at the press conference, and if I remember correctly, Professor Xu did not seem to deny that he had a model for materials research.

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

If that's the case, then that's probably the biggest takeaway of the day.

For a moment, the commotion and mood swings in the hall were a little violent, and everyone was waiting for the answer of the man on the podium.

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

This rep is a little interesting, and wants to focus on the model in his hand? Or do you have other ideas?

It is not known if it was the instructions of the AMSC superconducting company, or his own actions.

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

Of course, he wasn't prepared 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 materials research, but it is not as useful as you imagined. ”

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

"No one has ever relied on a mathematical model to develop a new material, it's impossible. All of you here are experts in the field of materials, and I believe you should be well aware of the role of mathematical models in materials. ”

After the words fell, the representative of AMSC Superconductor quickly asked: "Then may I ask Professor Xu whether he has thought about making this mathematical model public?" ”

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

Hearing this, Xu Chuan couldn't help but sneer, this is really a bit embarrassing β.

"If AMSC Superconductor is willing to disclose all patent licenses for free, I am also willing to disclose this mathematical model."

"If you can't represent AMSC Superconductor, I suggest that AMSC Superconductor come over with a capable representative. Next. ”

A press conference, if there is no AMSC superconductor company to make trouble, is quite perfect.

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

The point to pay attention to is that the follow-up work needs to strengthen network security and confidentiality.

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

It is not impossible for these 'capitalists' to steal or buy off researchers at the Kawakai Materials Research Institute and obtain material calculation models.

The material calculation model is not 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 put himself into work, but took the time to call Edward Witten.

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

"Hey, Xu Chuan, is there anything to find me?" After the call was connected, Witten's voice came from the phone, with a hint of exhaustion.

Xu Chuan heard this tiredness and asked with concern, "Mentor, what's wrong with you?" Feeling a little tired from listening to sounds? ”

Witten replied: "It's nothing, it's just a bit of a lot of work on CERN's side lately. ”

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

Edward Witten was silent for a moment, nodded and said: "Yes, but there has been no result, maybe what you said is correct, with the current equipment alone, it is difficult for us to find traces of dark matter." ”

After a pause, he continued, "The CERN side is almost giving up, and we are discussing an upgrade to the LHC. ”

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

Witten: "? ”

Xu Chuan: "This upgrade of the LHC should use the Bi series of 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 how this matter hasn't been announced yet? ”

Xu Chuan smiled: "Let's not talk about this, I want to ask CERN if he is interested in new superconducting materials?" CERN will be interested in a new high-temperature superconducting material with an atmospheric pressure of 152K, a critical magnetic field of more than 20T, and a critical current of 5500A/mm2 at 20T? ”

On the other side, Edward Witten was stunned with his mouth slightly open, and only came back to his senses after half a sound, swallowed his air in surprise and asked, "152K, 20T?" Are you sure? ”

As a theoretical physicist based at CERN for many years, he knows the performance of the Large Strong Particle Collider all the better.

The superconducting magnets used in LHC today are made of niobium-titanium (NbTi) superconducting materials, which can currently provide a magnetic field strength of 8T, and no matter how high it is, the reverse superconductivity phenomenon will cause the niobium-titanium alloy to return to normal.

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

Judging from the data, it has been completely blown up.

Xu Chuan nodded with a smile and said, "That's right, the latest superconducting material developed by the Chuanhai Materials Research Institute under my name has been completely tested and a press conference has been held." ”

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

Hearing this, Edward Witten immediately remembered the memories he had when he went to China to invite this student to participate in CERN's dark matter exploration project.

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

It's just that the speed at which he conducts research is inevitably too fast.

At most, in half a year, 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 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 can reach 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, used to find dark matter, should be enough anyway, right?

After thinking about it for a while, Witten then asked, "I'll talk to Lord Gross first, there will be a related meeting tomorrow, and I'll bring it up at the meeting then." ”

After a pause, he then asked, "By the way, I need you to provide a copy of the parameter data of the superconducting material, and in addition, is the superconducting material energy produced?" If it's just a product in the lab, I'm afraid it doesn't make much sense. ”

Xu Chuan nodded with a smile and said, "The data is no problem, I'll send it to your mailbox later." As for industrialization, I have found a way to industrialize mass production, and I am currently looking for a cooperative manufacturer, I believe that at the speed of Huaguo, it will not be long before it can be mass-produced. ”

Witten: "If that's the case, I'll go talk to the council." This is a good thing for CERN. You wait for my message, and I'll give you feedback. ”

Xu Chuan smiled: "It's troublesome for the mentor"

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

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

It is located in the largest controllable nuclear fusion base in China, with four major national scientific and technological infrastructures in the field of nuclear fusion research: Luyang superring (HT-7), fully superconducting tokamak device (EAST), EAST auxiliary heating system, and fusion reactor host key system integrated research facility (CRAFT).

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's eyes had a trace of complicated feelings.

He has worked here for more than ten years, and in 98 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 led the work here, and only retired to Mizuki a few years ago.

Even though he is gone, he is still keeping an eye on the news here.

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

For example, in 2012, the EAST device broke the world record and obtained a 20 million degrees Celsius high-parameter deflector plasma for more than 400 seconds; In 2017, a record stable 101.2-second steady-state long-pulse high-confinement plasma operation was achieved, and in 2018, a number of major breakthroughs were achieved, such as 100 million degrees Celsius plasma operation.

The results made him feel comforted and proud.

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

It's like a child raised by himself, although it has now gone out on its own, but there is also a sense of satisfaction and pride to see it go further on the road of controlled nuclear fusion.

"Yo, Lao Peng, what kind of wind blew you over?" In the building of the research institute, Academician Chen Mingji, who was working, got up with a smile to greet Peng Hongxi and Gao Hongming.

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

"We haven't seen each other in years." Peng Hongxi stepped forward with a smile and said with some sighs.

"Yes, after you left in 12 years, you also met at the 14th Academician Conference. Now, another five or six years have passed. Chen Mingji said with a smile after thinking about it.

"Come, come in and sit down."

In the office, Chen Mingji made a pot of tea, and after the three of them exchanged pleasantries for a while, Peng Hongxi said: "Let's get down to business, I came here this time because I want to discuss something with you." ”

Academician Chen Mingji smiled and said, "What's the matter?" Is it worth the trip you take to the mountains yourself? ”

"Last year, I agreed to the invitation of Academician Xu Chuanxu to help him complete the Jinling Controlled Nuclear Fusion Project, and now the project has been launched, and now it has entered a critical stage, Academician Xu has established a set of mathematical models for plasma turbulence in the chamber of a 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 about his old friend coming back to the mountain to assist the young man in establishing the Jinling Controlled Nuclear Fusion Project. It's just that he didn't care, and he didn't ask.

Now that he said that, he probably knew why these two were here.

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

On the other side, Chen Mingji pondered for a moment and said, "I'm sorry, I can't agree to your request." ”

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

Chen Mingji shook his head, restrained his smile and said, "It is precisely because I am clear that I refuse." ”

"The control model of plasma turbulence is undoubtedly critical to the operation of a controlled fusion reactor, but it is too risky for the EAST unit to change the control system."

"If the plasma in the reactor chamber gets out of control, then the consequences are catastrophic for the EAST unit."

"The JT-60SA Controlled Nuclear Fusion Experimental Reactor at the Fusion Research Institute in the Sakura Country QST is a lesson from the past, and if something like this happens to the EAST device, you and I will be sinners."

"So I can't agree to your request, the EAST device is everyone's brainchild, and I can't risk it."
