MTL - Into Unscientific-Chapter 463 boom! ! (Thanks to the lord of Chen Zui for the reward
“.”
Looking at Hou Xingyuan and Carlo Rubia who walked out of the backstage and talked happily on the surface.
Suzuki Atsuto's mind suddenly went blank.
This. Isn’t this style of painting right?
Why CERN cooperates with Chinese Academy of Sciences?
To know.
Although CERN and Kamioka Laboratories have an unresolvable hatred, the relationship between the two parties has deteriorated to the point that many times they are unwilling to even do superficial efforts.
For example, at the physics summit on the charmonium particle held in Kuala Lumpur in August last year, two representatives from CERN and Kamioka Laboratory scolded each other for several minutes, and even almost fought.
But on the other hand.
Although both parties wish each other to die.
But when facing the country of China, both sides will retain some tacit understanding that contains political overtones.
I won’t say much about the Kamioka Laboratory. I have introduced the matter of releasing pigeons from the Chinese Academy of Sciences once.
And CERN.
Indeed.
At present, some CERN scholars have indeed given a lot of help to the Chinese physics community.
It can even be said that the reason why Huaxia particle physics has developed in recent years is largely due to the scholars at CERN.
But it needs explaining.
When these scholars approached Huaxia, they basically communicated as consultants of their own universities, rather than as assistance through CERN projects.
This is somewhat similar to the commercial cooperation of European clubs in Chinese football. Nowadays, many European clubs will accept some young Chinese players for trial training.
For example, Atletico Madrid, Granada and so on.
These clubs belong to UEFA, and UEFA did give some green lights in the process throughout the process.
But in fact, it is the club that really helps, not a joint organization such as UEFA.
Actually.
CERN officials are quite repulsive to Chinese people. Although there are several postdocs every year—that is, postdoctoral fellows who are allowed to bring family members, but Staff positions are rarely approved.
Although in these years ATLAS, CMS, AMS, LHCb four experimental groups of CERN, more and more Chinese people are playing an important role.
But they are either in the postdoc mode, such as the cooperation between HKUST, Jinling University, Shuimu University, etc.
Either
migrant.
And Carlo Rubia's move now is equivalent to UEFA suddenly announcing a strategic cooperation with the Chinese Football Association:
As long as China has good seedlings, they can be sent to Europe casually. We will help you cultivate them here, and you don’t even need to consider labor certificates.
How can Atsuto Suzuki not be surprised?
Actually.
It was not only Atsuto Suzuki who was surprised, but also Zhou Shaoping and Xu Yun who were a little angry because of Bruce Arnold's rascal remarks.
Then Xu Yun glanced at the main screen.
After discovering that the camera and the sound receiver were moving towards Carlo Rubia, he quickly approached Academician Pan:
"Teacher, this is."
“As the saying goes, you can’t put all your eggs in one basket.”
Academician Pan smiled and pouted his chin in the direction of Carlo Rubia, and said in a low voice:
"The plan for CERN's next-generation collider has not yet been decided. The bigger the news, the better for them, plus some discounts promised by the Academy of Sciences. You can understand the details yourself."
Finished speaking.
Academician Pan strode towards Hou Xingyuan and Carlo Rubia, and greeted them warmly.
Xu Yun, the little transparent, stayed where he was and scratched his head, with a dazed expression:
"What does this mean?"
Zhou Shaoping on the side is obviously much more sensitive than him in this aspect. Seeing that Xu Yun hadn't figured it out, he made a point:
"Xiao Xu, think about what project Neon has? It's related to the collider."
Xu Yun was taken aback for a moment.
After a few seconds.
He couldn't help but slapped his forehead, suddenly said:
"I see, Academician Zhou, you mean ILC?"
Zhou Shaoping patted him on the shoulder, saying nothing.
Xu Yun looked at Atsuto Suzuki with some belated awareness, and couldn't help feeling a little bit of emotion in his heart:
So that’s what happened
Mentioned earlier.
Currently the highest particle collision energy level is 10 to the 13th power level, which is 13TeV.
If high-energy physics wants to continue to develop, at least the energy needs to be increased to the Planck scale, that is, the energy level of the collider must reach the 10^16 power TeV.
Theoretically beyond this energy level, new discoveries may be made in high-energy physics.
As for the blank space between 13TeV-10^16th power TeV, there is another very intuitive name:
Energy level desert.
The word desert is enough to explain everything.
So the current field of front-end particle physics has been thinking about increasing the level of the collider, and the first proposed device is called the International Linear Collider.
That is InternationalLinearCollider, referred to as ILC.
It is a linear accelerator about 20 kilometers long, and its energy level can reach 50TeV.
At the beginning of this project, it was planned to choose one of CERN, Fermilab and Neon.
However, in 2020, it was successfully acquired by Neon, and the total cost was about 100 billion Huaxia coins.
Although Neon gave ILC a yellow light in 22 years, it soon took it as a project to be built, and set aside an initial funding—there are rumors that the funding is about 5 billion Huaxia coins, But there is no real hammer, in short, the number will not be too small.
In other words.
For Atsuto Suzuki, he basically doesn’t have to worry about the handover and iteration of the Neon Next Generation Collider. He only needs to consider the project’s landing time?
But CERN is different.
After the ILC was snatched by Neon.
CERN immediately announced a new collider project, called the Future Circular Collider FutureCircularCollider, abbreviated as FCC.
Its orbital length will reach 100 kilometers, with a magnitude of 100TeV, and a total cost of 180 billion Huaxia coins.
However, this project has not been actually implemented, and the reason is very simple:
There is an energy-level desert in front of it. So much money invested in it may not have much effect.
So Carlo Rubbia has been working on this project all these years, and Huaxia has also been running around—because Huaxia's infrastructure is solid and cheap, and it is a well-deserved first choice.
And today’s press conference?
Not to mention dark matter, if one more particle can be discovered—especially an example of TeV level, it will undoubtedly be of great help to Carlo Rubia or the thousands of employees at CERN.
Carlo Rubia can throw the report on the table of the Council of Member States, and say with a straight chest that this particle is a leftover pearl on the edge of the energy level desert, and there may not be nothing in the so-called desert.
Maybe there are countless oil buried under the desert.
Of course.
Just don't get stolen by the eagle.
This is something beneficial to all of CERN, that is, Carlo Rubbia must be positive in his position.
In addition, Hou Xingyuan probably promised some other conditions to Carlo Rubia, such as the discount mentioned by Academician Pan—this thing most likely refers to the project quotation.
Although the profit of engineering infrastructure is definitely not as much as that of equipment, it must be the bulk of FCC's total expenditure. After all, the underground equipment with a total length of 100 kilometers.
As Hou Xingyuan, the dean of the Chinese Academy of Sciences, it is very easy to promise some discounts in this regard, and Xu Yun has no doubt that the rabbits still make money.
No wonder Xu Yun hasn’t seen Carlo Rubia since just now. The co-author went backstage to have a small meeting with Hou Xingyuan
Think here.
Xu Yun sighed without warning.
Although CERN may be able to overcome this difficulty, in the final analysis, I still need an accelerator.
Then he glanced at Elder Yang beside him again, feeling a little emotional in his heart.
Back then, Huaxia planned to build a super particle collider, namely CEPC.
But during the discussion, there was a huge difference of opinion.
Among the industry insiders who support CEPC, the most representative ones are academician Wang Yifang, director of the Institute of High Energy Physics, and Mr. Qiu Chengtong.
The representative of the opposition is Yang Lao.
At that time, Mr. Yang wrote an article "China is not suitable for building a super large collider today", and used seven reasons to oppose the views of Mr. Qiu Chengtong, the winner of the Fields Medal.
Academician Wang Yifang read the article that morning.
wrote an article titled "China is building a large collider, today is the time" to refute.
Objectively speaking, both parties are actually reasonable.
Mr. Yang’s reason is very straightforward:
The magnitude of CEPC is 100TeV+, which is a recognized energy level desert, and the reality is not fiction. It is very likely that you will find nothing if you invest 200 billion. It is obviously more cost-effective to invest 200 billion in education.
Academician Wang Yifang’s opinion is actually quite reasonable:
It's not that the country can't afford 200 billion funds. If the rectification funds are tricky, at least 150 billion can be spared in five years, and the country can provide 50 billion. No one can guarantee that this kind of national important weapon will be useful, but it must be there. Without this Things could really be gone.
all in all.
Because of the differences in opinions, the relationship between Mr. Yang and academician Wang Yifang is extremely bad now.
At the same time, there are many netizens in China who don't like Mr. Yang and academicians, so it is often seen that some netizens use the excuse of supporting one side to attack the other side.
Among them, Elder Yang's ability to withstand stress is better.
After all, the criticism he encountered was not a day or two. At that time, Mr. Yang, who was 94 years old, did not have much contact with the outside world.
But Academician Wang Yifang has had a hard time these years. He was at the peak of his research career at that time, and he often attended various conferences and accepted interviews.
Fortunately, last year he led the Daya Bay team to complete the measurement of the neutrino oscillation matrix angle. This is the largest contribution China’s local physics community has made to fundamental physics so far in reality.
It's a pity that the barriers to this achievement are relatively high, and many people don't know about it.
Both academicians are capable and devoted to scientific research. The current rigid relationship between the two is really regrettable and regrettable.
Actually not only in the field of scientific research.
Among the web writers, there are many examples of top authors who are very stiff.
It can only be said that people are creatures with emotions of likes and dislikes after all, and two people with strong abilities may not be able to see each other.
And the other side.
After Academician Pan came to him.
Carlo Rubia smiled heartily and took the initiative to shake hands with him:
"Hey Pam, haven't we seen each other in a few years?"
Academician Pan smiled back and saluted:
"It's been about six years, Mr. Rubia."
Carlo Rubia arrived in Rongcheng relatively late. At that time, Hou Xingyuan and another veteran academician of the Academy of Sciences were responsible for welcoming him. Academician Pan was not present in person.
So the current handshake is the first face-to-face meeting between the two in several years.
After letting go of your hand.
Carlo Rubia glanced at Atsuto Suzuki in the distance, and soon turned his attention to the big screen:
"Pan, your staff has introduced the LHC signal into the background, and you can issue the activation command at any time."
Academician Pan had a proper expression of gratitude on his face.
This gratitude is partly playful, but partly sincere.
Although CERN's entry is strictly speaking a mutually beneficial transaction.
But for Carlo Rubia personally, making such a decision still has to bear certain risks.
After all, if particles of the order of 923.8GeV did not exist, Carlo Rubia would definitely not have the best bargaining chip to convince the Council of Member States.
Of course.
This emotion was only fleeting, and Academician Pan's face soon became a little dignified.
Then he and Hou Xingyuan looked at each other.
After receiving Hou Xingyuan's signal.
Academician Pan pulled down his earphones and said into the microphone:
"The staff of the LHC accelerator, now enter the final confirmation process before starting the equipment. If everything is normal, please reply with an executable signal!"
After a while.
A huge English word appeared on the screen:
【ready】.
This word is followed by a small emoticon of 【^^】, which made the tense atmosphere of the scene a lot easier.
See this scenario.
Academician Pan no longer hesitated, took another deep breath, and said:
"Power on!"
Following Academician Pan's order.
Tens of thousands of kilometers away.
Switzerland.
The main LHC collision control room at CERN headquarters.
A middle-aged white man with a shiny forehead simultaneously pressed the start button.
Boom boom boom—
Unlike other colliders.
As the world's highest-level collision equipment, the tunnel length of LHC is also well-deserved first in the world - it is a full 27 kilometers long.
This time, the CMS is activated, which is a compact muon coil, which is a general-purpose particle detector.
As the device starts up.
The middle region of the CMS is injected with liquid helium to ensure that the superconducting magnets will not exceed the operating temperature.
Immediately after.
A proton synchrotron begins to accelerate the beam of lead ions.
This is a small linear accelerator, black and hard but very thin, making a constant crackling sound—this is the movement of a superconducting magnet entering a superconducting state.
After a while.
A dense ion beam is ejected from the nozzle of the proton synchrotron, and directly penetrates into the warm cavity of the main acceleration ring that has reached the operating temperature.
Within 49 microseconds.
The main acceleration ring is filled with hundreds of millions of small particles.
Then soon.
The total energy in the ion beam reached the order of 600 megajoules, and it was launched from the injection port like a fully charged bow and arrow.
26 nanoseconds later.
The two ion beams collided fiercely.
Well known.
The nucleus is approximately spherical in shape.
But when the atomic nucleus is accelerated to close to the speed of light, it becomes very narrow in the direction of motion due to Lorentz contraction, and the shape of the system is ellipsoid when it collides.
So ever since.
Countless pairs of ellipsoidal atomic nuclei traveling toward each other slammed into each other heavily.
Boom—
Countless particles exploded instantly, and various basic particles scattered out.
If these ion beams are a civilization, then this is the day of the destruction of civilization.
At the same time, because the energy level is much higher than the previous 11GeV collision, the event cutting of this collision is more obvious—because the higher the energy level, the higher the temperature.
Each particle collision can roughly cut out 100,000 events, and then the graphics processing unit performs the next stage of processing.
over time.
Trajectory jets of massive magnetic particles appear in the statistical background.
With the increase of chemical potential, the fourth-order moment first decreases and then increases near CEP.
at the same time.
CERN is not idle either.
NCQ Scale for Collective Elliptic Flow
Light nuclear output ratio.
Critical Behavior Local Heat Equilibrium Coefficient
Dilepton yield.
These data are recorded one by one.
Although these data have little to do with the particles to be measured, they can provide reference cases for other studies—even CERN cannot afford to carry out collisions of this magnitude every day.
Actually.
The last time a collision of this magnitude was carried out was 6 months ago.
10 minutes
15 minutes
20 minutes
over time.
CERN has collected more and more cases.
Academician Xu Yunpan. Hou Xingyuan. Zhou Shaoping. Yang Lao. Wittenthooft Polyakov Higgs.
Even Atsuto Suzuki and Makoto Kobayashi, who was far away in Neon, stared at the live broadcast screen intently.
They are waiting for an answer.
If the experiment fails.
Then, although the press conference of the Academy of Sciences is still an unprecedented success, it is somewhat unsatisfactory.
Like a prisoner, the shackles around his neck are released, but the shackles on his feet still exist.
at the same time
Witten's prestige will also plummet.
But if the experiment is successful.
Then Huaxia High Energy Physics will be like Andy who escaped from Shawshank Prison, standing freely on the ground, spreading his hands, and embracing the sky.
25 minutes
33 minutes
47 minutes
finally.
At the 59th minute of the experiment.
唰—
Suddenly, a screened and enlarged list of cases appeared on the main screen.
The number note of the case table is .
234491835.
According to the ratio of 100,000 events cut out by one impact, this is the 2300th or so impact.
Don't look at this impact sequence is not big.
It was introduced earlier that there can be 30 pairs of particles colliding in a cluster, which is considered a very high proportion.
The moment I saw this example table.
唰—
All the participants stood up from their seats almost at the same time, leaned forward, and looked at the main screen with shock.
At the first row.
Atsuto Suzuki staggered suddenly, fell heavily to the nearest seat, panting heavily.
Higgs opened his mouth slightly with a surprised expression.
Academician Pan's left hand drooping by his side suddenly clenched into a fist.
Witten's face froze, and was soon replaced by a burst of surprise.
Xu Yun's eyes widened, and a blush appeared on his face.
I see at this moment
On the case sheet on the big screen.
Around the interval of 950GeV, there is a .
Straight bumps!
Note:
Thanks to the leader of the reward Chen Zui, this owes more and more updates
