At this critical point when cooperation was about to be signed, the United States suddenly intervened temporarily, causing CERN to suspend continued cooperation.
To be honest, Xu Chuan really didn't expect this.
But reciprocity is the way to make friends.
Now that the United States has taken action, given his character, it is impossible not to respond.
It is difficult for him to intervene in the confrontation between major powers, but he can make the decision regarding the high-temperature copper-carbon-silver composite superconducting material he has developed.
Although the United States has developed high-temperature copper oxide-based superconductors with similar magnetic field strengths, the critical magnetic field is not the only influencing factor for superconducting materials.
Aside from critical temperature and critical current, the thermal conductivity is also a very critical attribute for superconducting materials.
After all, only a high thermal conductivity can keep the temperature below the critical temperature through coolants such as liquid nitrogen and liquid helium.
Especially for something like a controllable nuclear fusion reactor, the stability of the external field coil is related to the control of the ultra-high-temperature plasma that is hundreds of millions of degrees inside.
If the confinement magnetic field loses its effect, the consequences of the reactor can be referred to the JT-60SA of the small island country.
The moment the ultra-high temperature plasma in the reactor chamber loses control, the entire reactor will be torn into pieces by the violent plasma.
This is also the advantage of high-temperature copper-carbon-silver composite superconducting materials. It is more outstanding than ordinary superconductors in terms of critical magnetic field and thermal conductivity, and is more suitable for equipment such as controllable nuclear fusion reactors.
...
In Beihai Hotel.
After CERN suspended cooperation discussions, some theoretical physicists who came to participate in this meeting left, and some still stayed here.
Some want to see the follow-up situation, and some want to talk to Xu Chuan about whether China is still preparing to continue building the collider in the future.
After all, when CERN suspends technical support cooperation, it is not impossible for China to suspend the construction of the collider.
For these well-known scholars, traveling abroad is not a big deal, and they do not lack the money.
At this moment, in the hotel room, Professor Wilzek was holding hand-ground coffee and looking at Xu Chuan with some worry.
CERN's suspension of cooperation at this critical point is not a good thing either for China or for the young scholar in front of him.
On the side, Edward Witten frowned slightly and asked: "If CERN cancels the cooperation, will you continue to build the collider?"
Xu Chuan smiled, nodded, and said, "Don't worry, no matter how CERN changes or no matter how the United States instigates, our collider construction plan will never change."
After a slight pause, he continued: "And even if there is no cooperation, we welcome theoretical physicists from all over the world to come here to do experiments and research."
More than half of the research results in theoretical physics come from strong collider. This opportunity to let others use the collider you built for free seems a bit silly.
But for him and China, if they want to use this collider to build it into a world physics holy land and scientific research center, as well as cultivate China's own scholars, they are inseparable from it anyway.
of physicists.
Xu Chuan knew this very well.
And more importantly, if the construction of the collider is abandoned now, the status of CERN member countries may not be preserved.
Now that the United States has intervened in this matter, there will probably be some other combos in the future.
After all, this kind of confrontation between big powers cannot just take this one move.
In order to compress their development in the field of basic science, the United States will definitely follow up with a whole set of combos.
So now, the Large Strong Particle Collider must be repaired anyway.
Opposite him, Edward Witten nodded, and a smile appeared on his wrinkled face: "No one expected such a thing to happen. If you need help, you can tell me and I will try my best to do it.
"
Whether it is from the perspective of the friendship between tutor and student, or from the perspective of a theoretical physicist, he hopes that the large strong particle collider led by the student in front of him can be built perfectly.
Xu Chuan smiled. In this kind of confrontation between big powers, the power of an individual is too weak.
Although his mentor is known as the "first person" in the American physics community, it is impossible for him to have the ability to change these things.
But speaking of it, he really did have some things that he needed help from this mentor.
Smiling, he said: "Speaking of this, I really have something to trouble you, mentor."
Witten: "Huh? Whatever, as long as I can help."
Xu Chuan: "I want to recruit a group of physicists to come to China to do experiments and research. I need your help, mentor, to spread some news at CERN."
"Especially for physicists who are interested in things like sterile neutrinos, dark matter and dark energy, the tutor can help focus on attracting them."
"Believe me, even if we build the Large Strong Particle Collider from scratch, our speed will not be slower than the upgrade of the LHC."
Witten thought for a moment, looked up at Xu Chuan, and asked with a hint of curiosity: "Are you ready to compete with CERN?"
Although he had not taught this student much longer than Deligne, he knew the character of the student in front of him very well.
After listening to him say this, I roughly guessed what he was thinking.
Xu Chuan smiled faintly and said, "There's nothing wrong with that, right?"
"For science, only competition and collision can make it develop rapidly."
"I think you, tutor, should be very clear about the times in history when science and technology exploded. Especially during the competition between Hong Kong and the United States, a large number of achievements were made in everything from basic science to aerospace.
development of."
"While the reasons behind this may be dangerous, there is no denying that rapid progress can only be achieved through competition."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Laziness is the nature of any living thing. If there are no competitors, technology may still continue to develop under the organization of the country, but the benefits will be far less than if there is competition.
Opponents collide together."
"If there are two platforms in the field of high-energy physics, I think the development of theoretical physics will usher in a vigorous and brilliant new life. Maybe it will be short-lived, but the energy it explodes in this short period of time will be huge.
.”
Listening to Xu Chuan's words, Witten and Wilzek both nodded in agreement.
This is indeed true. Only when there is competition will we try our best to break through.
Just like the Cold War between the red and blue sides, it was also a time when various technologies were booming, such as the initial controllable nuclear fusion technology, manned spaceflight, lunar exploration projects, one small step for mankind...etc.
All were completed during that period.
Of course, more weapons and technologies were completed during that time, and a little carelessness may lead to the demise of human civilization.
But for China and the United States now, it is obvious that the focus of competition is not in weapons technology.
If there is investment and competition in the field of basic science, this will be a huge good thing for the entire civilization.
Of course, for Xu Chuan, promoting the development of physics is part of the idea.
The use of collider to attract physicists to China for research is on the one hand to prepare for competition with CERN, and on the other hand to expand China's influence in the physics community and gradually move the world's holy land of physics.
his purpose.
After all, there is now a high probability that CERN will terminate cooperation and start competition, and their original plan to use the Large Strong Particle Collider to directly transfer the holy land of physics in one step has basically been shattered.
Then all that's left to do is to take it slow, little by little.
When he completes the results of the complete body of sterile neutrinos and dark matter and dark energy, everything will come back again.
Now that the competition has begun, in order to win, he must make the most correct choice.
