The question raised by the representative of the American AMSC Superconducting Company made the representatives of the manufacturers who came to attend the press conference raise their heads with interest.
The development of a new type of material is not that easy.
Whether it is artificial SEI films or high-temperature copper-carbon-silver composite superconducting materials, they can be said to be hot areas in the materials industry, and have been studied all over the world for more than ten years or even decades.
However, after more than ten years of research all over the world, no results have been achieved. In the hands of Professor Xu, it was completed in just two or three years.
It would be a bit unbelievable to say that it was really just luck.
You could say you were lucky once, but if you say luck twice, I'm afraid not many people would believe it.
Not many people had thought about this before, but after representatives from the American AMSC Superconducting Company brought it up, representatives from these manufacturers quickly figured it out.
Rather than 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 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 to play a key role in this regard.
.
Especially before this, at the press conference for artificial SEI films, a researcher from the German Federal Institute for Materials Research asked questions about mathematical models at the press conference. If I remember correctly, Professor Xu did not seem to have any questions at the press conference.
Denied that he had a model for material research in his hand.
If one really masters such a mathematical model, it does not seem impossible to develop two materials that will subvert related industries in just two or three years.
If this is the case, then this may be the biggest gain today.
For a time, the commotion and mood swings in the venue became a little violent, 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 interesting. Want to focus on the model in his hand? Or do you 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 Sichuan-Hai Materials Research Institute, which is considered public and cannot be concealed.
Of course, he didn't plan to hide it.
After thinking for a while, Xu Chuan said: "The Sichuan-Hai Materials Research Institute under my name does have a mathematical model for materials research, but it is not as useful as you think."
"As for the artificial SEI films and high-temperature superconducting materials I studied, they were all made based on this model, so 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 finishing speaking, the representative of AMSC Superconducting Company quickly asked: "Have Professor Xu ever thought about making this mathematical model public?"
"For the materials community, an excellent mathematical model can greatly promote the development of the materials discipline. I believe you will consider it for the development of the materials community."
Hearing this, Xu Chuan couldn't help but sneer. This was really shameless.
"If AMSC Superconducting Company is willing to disclose all patent authorizations for free, I will also be willing to disclose this mathematical model."
"If you are unable to represent AMSC Superconducting Company, I suggest that AMSC Superconducting Company find a capable representative. Next one."
.......
A press conference would have been perfect if AMSC Superconducting Company had not disrupted it.
But for Xu Chuan, this is not a big deal.
What needs to be paid 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 "capitalists" to commercially steal or bribe researchers from the Chuanhai Institute of Materials and obtain material calculation models.
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 use it directly.
After the press conference on high-temperature copper-carbon-silver composite superconducting materials, Xu Chuan returned to the Sichuan-Hai Materials Research Institute. However, he did not immediately get into work. Instead, he took the time to make a call to Edward Witten.
The superconducting materials needed to upgrade the LHC Large Strong Particle Collider are a large order worth at least tens of billions of RMB. Such an order is worthy of his personal interception.
"Hey, Xu Chuan, what can I do for you?" After the call was connected, Witten's voice came from the phone, with a hint of fatigue.
Xu Chuan heard this hint of fatigue and asked with concern: "Teacher, what's wrong with you? You sound a little tired from your voice?"
Witten replied: "It's nothing, the workload here has been a bit heavy recently."
"Are you still looking for sterile neutrinos and dark matter?" Xu Chuan asked quickly.
Edward Witten was silent for a moment, nodded and said: "Yes, but there have been no results. 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: "We have almost given up here, 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 anymore. Are you interested in new superconducting materials? I have one with a normal voltage of 152K, a critical magnetic field of more than 20T, and a critical current of 5500A at 20T.
/mm2 new high-temperature superconducting materials, would you be interested?”
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Opposite, Edward Witten stood there with his mouth slightly open. He came back to his senses after a while, and swallowed the air in surprise and asked
: "152K, 20T? Are you sure?"
As a resident theoretical physicist 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 currently scheduled to be purchased 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 by 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 dark matter exploration project.
At that time, he, a 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 conducts research is a bit too fast.
In half a year at most, such great results have been achieved 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 intensity, 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, 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, does this superconducting material have energy production? If it is just a product in the laboratory, I'm afraid it won't be much.
significance."
Xu Chuan smiled and nodded, saying: "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 take long for it to be mass-produced.”
Witten: "If this is the case, I will go and communicate with the council. This is a good thing for me. You wait for my news and I will give you feedback."
Xu Chuan smiled and said, "I'm sorry to trouble you, mentor..."
........
Here, Xu Chuan is negotiating with his mentor Edward Witten, trying to intercept an order for high-temperature superconducting materials with 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 he retired and returned to Shuimu a few years ago.
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
Achieved many major breakthroughs such as 100 million degree Celsius plasma operation and so on.
Each achievement brings him comfort and makes him feel proud.
Now that he came here again, he couldn't help but feel a little nostalgic.
It is like a child raised by oneself. Although it has now gone out to explore independently, seeing it go further on the road of controllable nuclear fusion will give you a sense of satisfaction and pride.
"Hey, Lao Peng, what kind of wind brought you here?" In the institute building, Academician Chen Mingji, who was working at work, stood up with a smile to greet Peng Hongxi and Gao Hongming.
The two used to be colleagues, but he was not here before. 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 the Chinese Academy of Sciences in Luyang.
"We haven't seen each other for several years." Peng Hongxi stepped forward with a smile and said with some sigh.
"Yes, after you left in 2012, we only met once at the Academician Conference in 2014. Now five or six years have passed." Chen Mingji thought for a while and smiled.
"Come on, come in and sit down first."
...
In the office, Chen Mingji made a pot of tea. After the three of them chatted for a while, Peng Hongxi said, "Let's get down to business. I came here this time because I have something I want to discuss with you."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Academician Chen Mingji smiled and said: "What's the matter? Is it worth your while to go out to the mountain in person?"
"Last year, I agreed to the invitation of Academician Xu Chuanxu to help him complete the Jinling controllable nuclear fusion project. Now the project has been launched and has entered a critical period. Academician Xu has created a new system for the plasma in the controllable nuclear fusion reactor chamber.
Establish a mathematical model of turbulence..."
Listening to what Peng Hongxi said, although Chen Mingji still had a smile on his face, his eyes had changed somewhat.
He naturally knew about the fact that his old friend came back to assist the young man in establishing the Jinling Controlled Nuclear Fusion Project. However, he did not take care of it, nor did he ask about it.
Now that he said this, he roughly understood why these two people 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 we can complete the controllable nuclear fusion project, the better, so I came here this time.
I want to discuss with you and borrow an EAST device to complete the actual control verification of the model."
Opposite me, Chen Mingji pondered for a moment and said, "Sorry, I can't agree to your request."
Hearing this, Peng Hongxi showed a hint of surprise and said quickly: "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, suppressed his smile and said, "It was precisely because I knew it that I refused."
"The control model of plasma turbulence is undoubtedly crucial to the operation of a controllable fusion reactor, but the risk to the EAST device is too high to modify the control system."
"If the plasma in the reactor chamber gets out of control, the consequences for the EAST device can be catastrophic."
"The JT-60SA controllable nuclear fusion experimental reactor at the Fusion Research Institute in Sakura Country's QST serves as a warning. If something like this happens to the EAST device, you and I will both be sinners."
"So forgive me for not agreeing to your request. The EAST device is everyone's hard work, and I can't risk it."

PS: I went home to celebrate the Dragon Boat Festival and was stuck on the road for most of the day. There is only one chapter today. I will see if I can write more tonight and post it tomorrow (??????)??.
