Chapter 628 Look what we found? (Part 1)
As a piece of equipment that can be called a "state-controlled" level nowadays.
Although this tandem electrostatic accelerator is only in trial operation, the base has given it great attention and strong support.
For example, supporting materials for rubbing reports.
The base dispatch office, which was the department responsible for material allocation after the disbandment of the General Affairs Department, approved a large amount of rubbing paper and ink in one go.
To know.
Paper for rubbings is relatively [cheap] these days, but printer damage and ink are really rare items.
Nowadays, all domestic printers come from Mao Xiong’s original support project. The material uses selenium as a photoconductor. The design is quite primitive. You can’t even find a good 914 copier.
In a sense.
Every time a piece of paper is printed these days, a sum of foreign exchange is consumed.
This situation will continue until three years later, when the China Science and Technology Information Research Institute will cooperate with the Modu Photographic Equipment Factory to produce China's own electrostatic copier.
Therefore, for Zhao Zhongyao and others.
Although today is the trial run of the accelerator, after printing out these paper reports, the organizational investment is basically the same as a formal research.
No, it should be said that it is much more than formal research - formal research will not produce so many copies of the same documents, because at that time everyone has time to research slowly.
Therefore, facing these reports on the table, Zhao Zhongyao and others almost all entered a state of selfless research.
Thirty-seventh report.
Fifty-first Report.
Ninety-eighth report.
finally.
When the page number reached one hundred and thirty-nine, Wang Chengshu, who was responsible for assisting Zhao Zhongyao, suddenly raised his hand and said a piece of news that shocked Zhao Zhongyao:
"Report! Director Zhao, I have signs of an incident here!"
event.
This is a common term in particle physics. Generally, situations that are different from conventional parameters are called events, ranging from images to parameters.
A more representative example is the dark matter research of later generations. The LIGO project team will announce some so-called events every once in a while.
Later, this caliber was expanded to the field of astrophysics, such as FRB180301, FRB200428, and FRB202317 at the beginning of a certain angler’s new book next year, etc.
So Zhao Zhongyao immediately put down the documents in his hands, walked quickly to Wang Chengshu, and asked:
"Xiao Wang, what did you find?"
"Look at this."
Wang Chengshu quickly picked up a report from the table and handed it to Zhao Zhongyao:
"This is file number 139, which records three scattered particle trajectories and an integrated wake."
"There is nothing special about the particle trajectories. They are all known common particles, but this integrated wake is a bit strange."
Hearing this, Zhao Zhongyao pushed up his glasses, took the report in his hand and read it.
As a result, as he watched, a whisper came from his nose:
"Huh?"
As Wang Chengshu said.
The content of this report is actually very simple. There are only two images on it. After all, the analysis methods these days are still very primitive.
One image is a particle trajectory simulated by a cloud chamber. Judging from the energy level, it is obviously three electrons, which are very common particles.
The second image is a fitting diagram, which is somewhat similar to the state of a three-blade electric fan when it is at rest - the space is divided into three areas, and each fan page is an ellipse composed of two arcs.
If this description doesn't make sense to you, think of a rubber band with some space in the middle, then pinch both ends to stretch it.
Then put three such rubber bands together at 120° intervals, and you will almost have this fitting diagram, that is.
What Wang Chengshu calls the integrated wake.
In the current cognition of this era - note, in the current cognition.
The essence of the integrated wake is that when high-energy positrons and negative electrons collide, there is a high probability that they will annihilate and turn into photons to generate a bunch of hadrons. These hadrons are ejected along the direction of motion.
But the problem is
What Zhao Zhongyao and the others are doing this time is not the collision of positive and negative particles. The properties of the ions are the same from beginning to end - they are negative ions at the beginning and become positive ions after losing electrons.
Under such circumstances, how can annihilation of electrons and positrons occur?
So with this puzzling.
Zhao Zhongyao invited Wang Ganchang and several other high-energy physicists, and everyone discussed this drawing.
The first person to speak was Zhang Zongsui, who arrived at the base not long ago. This was also Xu Yun's "senior" at Cambridge University, but he graduated in 1936 and has no contact with Cambridge University now:
"Director Zhao, is it possible that there is an error in the equipment?"
Zhao Zhongyao quickly shook his head when he heard this and said:
"It's unlikely to be an error. First of all, this image is very clear, and the orbit doesn't look like it was misfitted. The probability of such a coincidence is really too low. I would rather believe that the Melody across the sea will be spotted on the street. Even if I get a headshot, I don’t believe that this happens by chance.”
"Secondly."
With that said, Zhao Zhongyao picked up another report from the table and handed it to Zhang Zongsui:
"This is another document that Xiao Wang just found. The superiors also observed this integrated trajectory map. Take a look."
Zhang Zongsui took the report and read it for a while, then put it back on the table, considered it and said:
"Well, it is indeed another integrated trajectory. With this image to prove it, it seems unlikely to be a coincidence."
See this situation.
Another scholar raised his hand. This person was the young expert who asked Xu Yun before if there was a way to counter the British.
According to this person's self-introduction, his name is Yang He, and he just arrived at the base not long ago.
Although Xu Yun has not heard of his name much in later generations, there is no doubt about his ability to be included in this expert group.
Yang He raised his hand, paused, and made a guess:
"Director Zhao, is it possible that it is the polarization state of certain particles at high temperatures? For example, muons?"
This time.
The reaction of everyone at the scene was obviously much hesitant.
Muons, also known as muons, are also called muons.
Muons are the second-generation leptons discovered in 1936. They are the prototype of the Minovsky particle in Gundam.
Anyone who has driven a Gundam knows this.
In some situations, muons will have their spin axis perpendicular to the external magnetic field and parallel to the direction of motion. Such muons whose spin axes are highly aligned are polarized muons.
One characteristic of polarized muons is that they may experience some out-of-control states over a wide range of temperatures. It is not impossible for an integrated trajectory similar to annihilation to occur.
After all, the voltage gradient within the accelerator varies greatly during the entire process, causing the heat energy to be dispersed equally unevenly. In some places, the difference can even vary by dozens of degrees every few centimeters.
But soon, Zhao Zhongyao also denied this speculation, pointing to Wang Ganchang's report:
"It's unlikely to be a polarization state - Comrade Yang He, look here, 14.626, the magnetic coupling parameters are not quite right."
"Muons are mainly produced by the decay of pions in a very short period of time. The theoretical magnetic field fluctuation frequency coupling value should be below 3, but here it is more than 14."
"In addition, according to a result I deduced a few years ago, even if the muon will show polarization, it can only be generated between the target and the first-stage deflection magnet, and it can never appear in the final state."< br>
Hear this.
Xu Yun on the side couldn't help showing a look of surprise.
As expected of Zhao Zhongyao.
Xu Yun was not prepared to interfere in the discussion of these big guys this time. After all, he also wanted to see how far the rabbit theorists could advance their theory without external help.
Of course.
This is not a test or test for these big guys - Xu Yun doesn't have the nerve to do such a thing in front of these seniors.
His main purpose for doing this was to have an intuitive understanding of the rabbits' abilities, so that he could consider how to kick history's ass next.
After all, I will leave the dungeon one day, and the follow-up work will definitely need these big guys to finish it off. (In order to prevent some readers from thinking about the new book above, the copy will be completed soon. Let’s make a prediction here. Don’t think blindly. It’s early)
But what Zhao Zhongyao said now obviously surprised Xu Yun.
Tell the truth.
It's normal for Zhao Zhongyao to come up with the first reason.
After all, he was engaged in extra-scattered radiation research back then, so it is not surprising that he is sensitive to magnetic coupling parameters. He can even be said to be the first person in the country in this regard.
But to be aware of the second concept is outrageous.
To know.
There are actually three types of muons produced by accelerators, namely surface muons, cloud muons and decay muons.
Surface muons are produced by the decay of pions parked near the target surface. Their situation is extreme after all - this particle has only a positive charge.
Because the negative pions are captured before they decay, no negatively charged surface muons are produced.
Cloud muons are produced between the target and the first-stage deflection magnet, and the third decay muon is produced by pions during their flight.
Among them, only surface muons and cloud muons will appear polarized, and their positions are in front of the first-stage deflection magnet. However, this recognition should not be officially recognized by the physics community until 1972.
Now Zhao Zhongyao actually stated this theory eleven years in advance. How could Xu Yun not be surprised?
Suddenly.
Another thing came to Xu Yun's mind.
If I remember correctly, it seems that Zhao Zhongyao did publish a paper "Theangular distributions of the alpha-particles and of the gamma-rays from the disintegration of fluorine by protons" back then, in which he mentioned the muon polarization interval?
However, this paper was published in 1950. At that time, there were no electrostatic accelerators in China, so Zhao Zhongyao could only roughly guess through his own experience that the polarization range of muons should be before the magnet deflected by 65.7°.
The first-stage deflection magnet, that is, the deflection angle of the muon’s actual polarization interval is.
51.4°!
If you continue to think about it from this perspective.
Maybe in the original history, after the rabbits had the 2.5MeV electrostatic accelerator, Zhao Zhongyao had actually further calculated the deflection angle of the muon's actual polarization range?
Xu Yun dare not say that this guess is 100% true, because Zhao Zhongyao himself has never said this, but at least logically Xu Yun can't think of any reason to refute it.
Back then, when conditions were unavailable, a range was roughly deduced. How could Zhao Zhongyao be able to resist experimenting when conditions were met?
Anyway, Xu Yun personally thinks that the probability is very low.
What a pity.
Due to various blockades at the time, Zhao Zhongyao, or many domestic theoretical studies or speculations, were unable to communicate with the international scientific research circle - in fact, many international scientists at that time were very welcome to communicate with rabbits, because Qian Wu's teacher Guo Zhao Zhongyao, Lu Guangda and others are all Chinese.
But now that the four-way trade has been concluded, John Bull and German Xu Yun are not sure, but Gaul and Mao Xiong should be able to open an opening for communication.
Think of this.
Xu Yun also has the answer to the choice of which side of history to kick next.
Of course, the intensity of the kick needs to be observed - the discussion on the spot is not over yet.
After Zhao Zhongyao denied Yang He's guess, several more experts spoke:
"Is it possible that it is an internal problem?"
"It's unlikely. Look, their quantum numbers add up to 0."
"Is that the influence of surface waves? Lao Zhou, you are an expert in this field, what do you think?"
"No, it's impossible. Surface waves should have deformation, but even with our precision, we still can't find the deformation."
In the end, even Lao Guo became interested, and this half-full master of particle physics also joined the discussion.
Then I was rejected because the questions I asked were too outrageous.
all in all.
Everyone discussed it for half an hour, but still couldn't find a suitable explanation.
But even so, some of the cognitions of these big guys during the discussion were still far beyond Xu Yun's expectations, making him increasingly ready to kick his butt.
But just when Xu Yun was about to speak, in the scene that was a little quiet because he couldn't think of an explanation, someone suddenly spoke again:
"Let me tell you, is it possible that the final particle has another form before hadrons, and this form appears in a very short period of time in a... well, hadronized state, thus giving it the ability to eject? Energy? ”
Swish——
As soon as these words came out, everyone, including Xu Yun, turned to look at the source of the voice.
The person who made the sound had a square face, slightly fat around the lower jaw, and wore a pair of brown glasses with thick frames. He was probably in his early 40s.
Xu Yun actually knows this person, he is Zhu Hongyuan, that is.
Future Chinese Academicians, and
The main proposer of stratotron theory!
Seeing everyone looking at him, Zhu Hongyuan couldn't help but said again:
"Everyone, this is just an idea of mine. After all, strong force will become weak at small intervals of time and distance. This is a well-known knowledge."
"In addition to time and distance, can momentum also be an inducement?"
"If this inducement exists, then suppose, I mean hypothesis, that a smaller particle was originally stationary within the ion, but gained stronger momentum due to the impact."
"This momentum makes this particle become somewhat deformed and different from its original self."
"At the same time, due to certain things inside...well, let's call it rules, certain rules restrict this particle from existing on its own."
"So it released part of its energy and decomposed another particle. Then these particles were combined with another anti-particle with smaller energy, and then hadrons were synthesized one by one?"
Zhu Hongyuan spoke and gestured at the same time, and since there was no data calculation involved, everyone at the scene quickly understood his thoughts.
Faced with this explanation.
Some people at the scene were thoughtful and seemed to be stimulated.
Some people frowned, obviously not agreeing with this view.
There are also some people who have expressionless faces and cannot guess what they are thinking.
But on the edge that no one noticed, Xu Yun's heartbeat had already jumped to over 150 beats per minute!
wtf?
Is this going against heaven? !
Note:
Yesterday I saw a comment asking me not to exaggerate these Chinese scientists. Let’s put it this way, I opened this copy just for them, and a lot of my content is the real deeds of these big guys, either from papers or autobiographies—— I brought the doi for my thesis, the title of the book for my autobiography, and for some of them I also attached the page number.
If you say I'm exaggerating, just come up with arguments to refute me. If you say I'm exaggerating and you can't provide any evidence to refute it, why don't you just say that the atomic bomb and the hydrogen bomb are also fabricated.
After this dungeon was opened, I really saw a lot of outrageous comments, but I became more and more convinced that this dungeon was opened correctly. (End of chapter)
