After preliminarily finalizing a set of different plans, Peng Hongxi and Gao Hongming temporarily left to prepare.

As for Xu Chuan, he turned on the computer and clicked on the mailbox.

With his fingers tapping lightly on the keyboard, he wrote an email and sent it out.

The recipient is Professor Tillmann Lunt of the Max Planck Institute for Plasma Physics.

Professor Tillmann Lundt, a Germanic physicist who currently holds the position of Director of the Planck Institute for Plasma Physics, met several times at CERN and exchanged academic views and contacts.

Through him, it should be possible to contact the Planck Institute for Plasma Physics to complete the purchase negotiations for the old ASDEX unit.

Of the four controllable nuclear fusion reactors he has included in the purchase plan, he is more optimistic about the old ASDEX unit at the Max Planck Institute for Plasma Physics and the Alcatel C-Mod compact fusion reactor at the Massachusetts Institute of Technology.

The ASDEX device is very complete, and he is relatively familiar with the Planck Institute for Plasma Physics, knows each other's situation, and can negotiate conditions.

As for the Alcatel C-Mod compact fusion reactor, it was due to economic and budgetary pressures that Mi Guo Energy decided to stop its operation.

Starting in 2012, C-Mod has been discontinued for seven years. The economy of Zai is now declining, and the plan and arrangement to restart it can be said to be far away.

Therefore, there is hope that it can be bought, but in this regard, the help of the state is needed.

As for which one to choose, it depends on which one can be discussed, which is more appropriate.

And if the ASDEX device and the C-Mod device can't be discussed, he will only consider the other two.

Professor Tillman Lunt replied much faster than Xu Chuan expected.

In the afternoon, Xu Chuan received an email prompt, and Professor Tillman Lent replied with an email expressing curiosity and asking him why he had purchased an ASDEX device.

Of course, Professor Tillman Lunt is also interested in high-temperature copper-carbon-silver composite superconducting materials, and if he can, he would like to have a video call between the two of them.

After receiving the email, Xu Chuan quickly replied to him with an email and made an appointment for a video call.

Today, Professor Tillman Lent is interested in high-temperature copper-carbon-silver composite superconducting materials, so there is a drama and some talk about the purchase of old ASDEX devices.

After making an appointment for a video call, Xu Chuan returned to the laboratory, and was just about to enter the laboratory to speed up the optimization progress of high-temperature copper-carbon-silver composite superconducting materials, when CERN called him.

Calling him was Professor David Gross, CERN's Board Chair.

"Xu, long time no see. Congratulations on your election to the title of Academician of the Chinese Academy of Sciences and the Chinese Academy of Sciences. ”

Gross congratulated with a smile, he is actually an academician of Huaguo, and was elected as a foreign academician of the Huaguo Academy of Sciences in 11 years.

Of course, foreign academicians are more of a title and a lifelong honor, and the biggest difference between them and local academicians is that they cannot mobilize the huge resources of the country like local academicians.

However, it is precisely because of the title of foreign academician that Gross knows how much energy he has and how much resources he can mobilize after being elected as an academician in China, which is far beyond the title of national academician in the United States.

Xu Chuan smiled and said, "Thank you." How have CERN been? ”

Gross sighed and shook his head, "It's not good, we haven't made any progress in the exploration of dark matter and dark energy, what you said at the beginning was right, with the current performance of LHC, it may be impossible to find dark matter and dark energy." ”

After a pause, he continued: "Listen to Witten, you have recently developed a new type of high-temperature superconducting material?" Want to trade with CERN? ”

Gross wasted no time and asked straight to the point.

Xu Chuan nodded and said, "That's right, high-temperature copper-carbon-silver composite superconducting materials, think about it?" ”

Gross: "We've shown me the superconductivity parameters and data related to this material, and judging from the data, it's undeniable that it's really good. ”

"But the upgrade of LHC is not a trivial matter, although the critical magnetic field superconductivity performance of 20T is indeed very attractive, but the council is afraid that it will be more inclined to more stable materials, and your research and development time is too short."

Xu Chuan smiled: "The short time does not mean anything, excellent materials can further improve the performance of the LHC, I believe the CERN Council will consider it." ”

Hearing this, Gross nodded, and did not deny it: "Indeed, excellent materials are more attractive, but LHC can be said to carry the mission of most of the theoretical physics community, and this upgrade is related to the future exploration of dark matter and dark energy, so even if I personally prefer the better materials in your hands, it may not be able to pass the council's consultation." ”

Xu Chuan frowned slightly, and said: "Compared with the superconducting materials provided by Sakura Country, the performance of the copper-carbon-silver composite material in my hand is obviously better, so can't it convince the council?" ”

Gross sighed and said, "If you can develop this material about half a year in advance, then this is probably not a problem." ”

"The problem now is that the superconducting materials in your hands have been around for too short, and the new materials have not been proven, which is very scrupulous. The BI material in Sakura Country has been around for nearly a year, and many manufacturers are currently using this material. ”

"So the council side should be more inclined to stabilize the material."

"What's more, the materials in your hands only exist in the laboratory at the moment, and have not yet been mass-produced."

"It's also a long time from the lab to mass production, and CERN can't afford to bet its hopes on that. After all, CERN is not mine, and although the supervisors of the member states do not manage things much on a day-to-day basis, we are funded by them. ”

"If the supervisors strongly disagree, the board will consider their opinions."

"Of course, I'll try to do some more at the council."

Xu Chuan nodded and said, "Understood." This is normal, LHC is a large collider, and the upgrade naturally needs to consider stability. ”

After a pause, he continued: "But I think that if you want to search for traces of the existence of dark matter and dark energy, I'm afraid it is not enough to upgrade the collision energy level. ”

Hearing this, David Gross raised his eyebrows and asked, "What do you think should be done?" ”

Although this person is now proposing this statement is a bit suspicious of cutting off orders for superconducting materials, he has to pay attention to the matter involving dark matter and dark energy traces.

After all, in the entire high-energy physics community, if you want to say that you have the deepest research on inert neutrinos, dark matter, and dark energy, the young man on the other side of the phone said second, I'm afraid no one dares to say first.

Inert neutrinos and related theoretical data were discovered and made by him, and in the field of the connection between conventional matter and dark matter, his opinions and statements must be seriously considered, not to mention CERN, even the entire physical community.

Coupled with his research in mathematical physics and his ability to use mathematical methods to explore physical particles, his ability in today's field of high-energy physics ranks not only first, but also at least in the top three.

In the second half of last year, he and Witten and others personally went to China to invite him to participate in CERN's follow-up exploration work, wasn't it because of his outstanding ability?

Xu Chuan: "Compared with the collision energy level, I think the optimization of the detector may be more appropriate. ”

"Blindly increasing the collision level is not the solution to the problem, because sometimes, it may not be that the collision level is not enough, but that our observation methods are relatively backward, and even if it appears, we can't see it."

Gross thought for a moment and said, "If that's the case, then where do you think our detector should be upgraded?" ”

Xu Chuan smiled and said, "This is not within the scope of free consultation." ”

"Actually, I think building a large strong particle collider in China may be more in line with my goals than upgrading CERN."

"And before, I communicated with the national government, and Huaguo did have the idea of building a large strong particle collider, especially after the discovery of inert neutrinos, the high-level officials have approached me and asked if there is a need to build a collider."

"It's just that I have some other projects in my hands right now, and there are really not many physicists in China at the moment, so the plan to build the collider has been delayed."

"If our country builds a large strong particle collider, I believe that with China's infrastructure capabilities, the construction speed will be faster than upgrading the LHC, and with me, I believe that the discovery of dark matter and dark energy will be ahead of CERN."

On the other end of the line, David Gross was silent for a moment.

Honestly, that's true.

With Huaguo's capabilities, if the current decision is to build a large power collider, I am afraid that it will go all out to complete the upgrade of the LHC one step ahead of CERN.

And this one on the phone, I'm afraid he thought about leaving the glory of discovering dark matter and dark energy in Huaguo from the beginning.

The fact that CERN was able to upgrade to various countries so smoothly was that the discovery and perfection of the Higgs particle provided value on the one hand, and the discovery of inert neutrinos provided prospects on the other hand.

Dark matter and dark energy, this is a completely new goal, is a direction beyond the Standard Model.

Without this direction, CERN may not be able to obtain upgrade funds so smoothly.

At present, the world is concerned with the LHC, a large strong particle collider, and countries have no choice but to concentrate their funds in the high-energy field on this area.

But if the news of the construction of a large strong particle collider comes out in China, it will definitely be a blow to CERN, and it will be even more difficult to ask for funding in the future.

After thinking for a moment, David Gross spoke: "If CERN procures the high-temperature superconducting materials you have in hand, will you provide the direction and technology to upgrade the detector?" ”

Xu Chuan smiled and said, "It depends on how much CERN will purchase." ”

"Actually, for CERN, it's definitely not a loss-making business. Believe me, the performance of high-temperature copper-carbon-silver composite superconducting materials will satisfy you. ”

"And in terms of its performance and stability, I can make a guarantee, which can be written into the contract at that time, and if there are some problems caused by the superconducting material itself, I can be responsible or even compensated."

Gross was silent for a moment, and said, "I'll bring it up again at the next council meeting." ”

I have to say that this person's words did make him change his mind, and he originally called this time to think of refusing politely.

As he said in the exchange, from a practical point of view, the upgrade of the LHC Large Strong Particle Collider, the CERN Council is more inclined to the already stabilized BI high-temperature superconducting materials. Even if its superconducting properties are not as good as copper-carbon-silver composites.

But for such a large-scale project, it is important to be able to achieve stable completion and meet the forecast plan.

Xu Chuan smiled and said, "Then it's troublesome Lord Gross." ”

Hanging up the phone, Xu Chuan looked at the phone with a black screen and smiled.

To be honest, he is actually a little black-hearted this time.

Because he is very aware of CERN's upgrade experience, in later generations, the first upgrade of LHC did not allow him to find traces of dark matter and dark energy in his previous life, not because the collision energy level is not enough, but because the performance of the detector is not enough.

Later, LHC upgraded and optimized the detector and adopted new technology, which found the traces and data of the existence of dark matter and dark energy.

And he is very clear about the upgrade route and technology of the LHC detector.

In other words, he is not trading with his own technology, but with CERN's own technology in the future.

Of course, for CERN, this is not a loss.

On the one hand, there is time, and he can bring the optimization of the detector years in advance, and for science, every second is a must.

A few years in advance, it is possible to discover more results.

On the other hand, the performance of the high-temperature copper-carbon-silver composite superconducting material in his hand is indeed better than that of the Bi superconducting material in the small island country.

Of course, on the Large Strong Particle Collider, he left something else behind.

After all, after he completes the controlled nuclear fusion project, the large strong particle collider project will also start, and he needs to retain some key technologies to make the domestic collider surpass CERN's LHC in performance.

In this way, he can attract many physicists from all over the world to work for him and China.

As for the discovery of dark matter and dark energy, he did have the idea of staying in China at the beginning.

But now the controlled fusion project has some problems, and he needs something more to ensure that the reactors can be traded from the Germanic countries or the United States.

Among them, high-temperature copper-carbon-silver composite superconducting materials are the key. He needed to ensure the performance and status of high-temperature copper-carbon-silver composite superconducting materials in order to successfully complete the purchase.

CERN's procurement is undoubtedly a guarantee of quality.

As for the discovery of dark matter and dark energy, it doesn't matter if it's ceded to CERN.

He will have a more important graviton theory in the future.

Compared with dark matter and dark energy, if gravitons are discovered, this is what will really change the development of mankind and allow mankind to leap from planetary civilization to space civilization.

PS: Today's blind date probably failed again. Woo woo woo ┭┮_┭┮, to be honest, I like the woman, at least the appearance is the type I like, but it's a pity that people don't seem to be very interested in me.

Is there a big guy in love, can you give me some advice?
