In the office, the atmosphere was quiet.

For David Gross, the things Xu Chuan said, although they all made sense from a personal point of view, did not meet CERN's expectations at all.

In other words, it did not meet the expectations of the Member States behind CERN.

Especially in the United States, the United States is more eager to make a breakthrough in controlled nuclear fusion technology.

After all, the advent of controlled nuclear fusion technology has shattered the fragile order that the international community has barely maintained.

You must know that energy, for human civilization, or for any civilization, is a prerequisite for the development of society and science and technology.

Throughout ancient and modern times, all activities of human society are inseparable from energy, from clothing, food, housing and transportation, to culture and entertainment, a certain amount of energy must be consumed directly or indirectly.

It is an important material foundation for the survival and development of mankind, the driving force of human social and economic development, and one of the pillars of modern human civilization.

Energy is equivalent to the blood of civilization, it drives the pace of civilization. The more modern a city is, the more dependent it is on energy.

And this precondition has now been broken.

For a country, or a civilization, if the energy problem is solved, it can be said that all the contradictions arising from the lack of productive forces will be solved.

The realization of controlled nuclear fusion is bringing about such changes.

In this field, if the United States, which has always regarded itself as the international leader of the world's police, cannot keep up with the pace in a short period of time, then its status will inevitably decline.

But for the United States, this is an unacceptable change.

Therefore, compared with the European Union, the United States is more eager to make a breakthrough in controlled nuclear fusion technology to continue to maintain its position.

And this time the CERN Council deal undoubtedly has the intervention of the United States.

Of course, other CERN member countries also hope to obtain high-temperature copper-carbon-silver composite superconducting material technology, or a batch of materials, from China.

After thinking about it for a moment, David Gross put the idea along.

"Exchange a batch of high-temperature copper-carbon-silver composite superconducting materials?" Xu Chuan asked.

Lord Gross nodded and said, "Yes, if I can obtain a batch of high-temperature copper-carbon-silver composite superconducting materials, I have a greater confidence in convincing the council." ”

"Of course, aside from the technology deal, CERN can pay some additional funds to purchase this batch of superconducting materials."

Hearing this, Xu Chuan thought about it.

CERN hopes to obtain a batch of high-temperature copper-carbon-silver composite superconducting materials, which is probably the final bottom line of this exchange.

As for the purpose of their need for these superconducting materials, it is naturally related to controlled nuclear fusion technology.

This is something that both sides know, but they just don't say it.

After thinking about it for a moment, he felt that this condition was not impossible.

Superconductors with high critical magnetic fields are essential materials for controlled nuclear fusion, but they are not without alternatives.

High-temperature copper-carbon-silver composite superconducting materials have advantages in terms of magnetic field strength, but there are also some low-temperature superconducting materials that can achieve this level of magnetic field strength.

It's just that there are gaps in thermal conductivity, critical current density, superimposed magnetic fields, etc.

If the core fusion reactor is expanded and the superimposed magnetic field is controlled, it is not impossible to approximate the plasma.

He is not worried that the EU will be able to make a breakthrough in controlled nuclear fusion technology after obtaining this batch of materials, because there are two other key factors at hand.

One is the mathematical model of high-temperature plasma turbulence, which is the key to constraining the operation of the plasma inside the fusion reactor.

The other is the first wall material, which is even more difficult.

If there is any hope for the mathematical model set of the top mathematicians in the European Union for high-temperature plasma turbulence, the first wall material is extremely difficult and impossible in a short period of time.

You must know the first wall material, they also came up with luck.

Under the condition that the core material manufacturing technology is not leaked, even if the raw materials are obtained, it is difficult to reverse it.

Therefore, it is not impossible to trade a batch of high-temperature copper-carbon-silver composites to CERN.

And the technology in CERN's hands is not dispensable.

Not to mention the rest, the high-energy and particle detector reserve technology in CERN's hands is what he needs.

Because this technology involves the observation of dark matter.

In his previous life, he observed dark matter through the high-brightness LC-LHC collider, and the construction of the high-brightness LC-LHC collider is in 2025, which is enough to show that the current CERN has the corresponding high-energy and particle detector reserve technology in its hands.

There is no doubt that this is what he and Huaguo need.

It's just that buying and selling can't reveal your intentions, just like buying something in the antique street, the first thing you ask about is better not to put it on the thing you want.

If CERN knew that he had what they desperately needed, he would definitely sit on the ground and raise the price.

But now, it's worth trading a batch of high-temperature copper-carbon-silver composite superconducting materials in exchange for CERN's high-energy and particle detector reserve technology.

After confirming that this deal could be reached, the chairman of CERN also relaxed a lot on his face.

Although he will step down as CERN president in the second half of this year, and his term of office is up, he does have physics at heart. During his tenure, he not only facilitated the entry of China into CERN as a member state, but also laid the foundation for subsequent cooperation between CERN and China.

After initially finalizing the cooperation with CERN, after sending off David Gross and Edward Witten, Xu Chuan returned to the office.

"Tang Ran, here is a list of books and papers, please go and buy them."

In the office, Xu Chuan called his assistant and handed over the paper torn from his notebook, which was the names of books and a list of papers he had listed.

With the report meeting and CERN out of business, it's time to deal with his own mistakes.

He made the mistake of introducing the undisclosed small polaron theory of strong electron-phonon interaction systems in his unified framework paper on strongly correlated electron systems.

It may not be a big deal to others, but for him, it's a mistake that shouldn't be made.

Because scientific research must always be rigorous, even if the small polaron theory of strong electro-phonon interaction system is the result of his own work, he should not make such a rudimentary mistake.

And if you make a mistake, you will naturally have to be punished.

When he used to teach his students, one of the punishments for students who made mistakes or failed to meet the goals was to make a list of books and set a certain time to read them, and then come back to the assessment.

He himself is no exception.

Reading a book may not be a punishment for him, but there is no doubt that reading the prescribed book within the allotted time requires him to devote all his free time to it.

And the follow-up assessment is not so easy to pass.

Tang Ran took the paper and glanced at it curiously, the clean and tidy paper was densely packed with all kinds of books, including "", there were two or three books in a row, and this piece of paper was almost directly written.

According to a rough estimate, the number of these books is probably in the tens or hundreds.

Although he was a little surprised why he suddenly bought so many books, Tang Ran didn't ask much, but just said, "Professor, will these books be sent to the office or your villa after they are bought?" ”

Xu Chuan thought for a moment and said, "One-third will be sent to the villa, one-third will be sent to the office here, and the remaining one-third will be sent to the Xinghai Research Institute." ”

The rest of his life was pretty much like this.

Tang Ran nodded: "Is there a plan for that?" For example, which part is sent to the villa and which part is sent to the office? ”

Xu Chuan: "Let's follow the order of the form." ”

After a pause, he looked at Tang Ran, his eyes fell on her weak arm, and after thinking about it, he said: "There are so many books and thesis materials, you and Lu Ling are afraid that they can't move, find two male comrades to help move them." ”

If only the school had a male assistant for him, he could just leave it to the male assistant to do.

It's not good to be all female assistants, and in daily work, if you encounter this kind of work that requires manual work, it is almost difficult for female comrades to do it.

Tang Ran smiled and said, "Don't worry, professor, I'll take care of it." ”

Xu Chuan nodded, didn't think much about it, and left the office after handing over the work of purchasing books and papers to the assistant.

The report on "Unified Framework Theory of Strongly Correlated Electronic Systems" came to a successful conclusion, and after settling the cooperation with CERN, he finally had time to visit the Kawakai Materials Research Institute.

And over there, the test results of improved superconducting materials are still waiting for him.
