Chapter 359 – The Research Group Started

Chapter 359 The research group started

Listen carefully.

It is rumored that it is a psychic beast hidden under the table of the Ksitigarbha Bodhisattva, who can identify everything in the world by listening.

Its image is an auspicious beast with a tiger head, one horn, dog ears, dragon body, lion tail and unicorn feet.

Outwardly, it looks like a dragon but not a dragon, a tiger but not a tiger, a lion but not a lion, a unicorn but not a unicorn, a dog but not a dog, and the unicorn represents arbitrariness.

In a sense.

Di Ting and Gravity Gradient have a very high overlap in function:

They all rely on their own abilities to perceive the general trend of the world, to explore the starry sky, and to search for the dark world.

With one sweep, nothing can hide.

Therefore.

Xu Yun gave the project team such a name, which belongs to the oriental romance unique to Chinese people.

Xu Yun’s team this time has fourteen members, ten men and four women.

Two of them are seniors, eight are master students, and four are doctoral students.

As for Lu Chaoyang’s identity.

is the guidance of the research group.

Literally a lower status than Xu Yun, but Xu Yun and Lu Chaoyang don’t really care about this difference.

Come to the operating table.

Xu Yun and Lu Chaoyang looked at each other, and Lu Chaoyang gave him a look with a tacit understanding, the meaning was quite obvious:

Hold me, just treat me like a wooden man, what should you do.

It is common sense in scientific research cooperation that strong guests do not overpower masters—for example, Academician Pan and Zhao Zhengguo, who have higher standards than the Di Ting research group, will have similar tacit understandings in their groups.

One mountain cannot accommodate two tigers. This situation may be encountered in the teaching and academic fields, but it rarely happens in the front-line project team.

Seeing this, Xu Yun nodded slightly to Lu Chaoyang, then turned around, cast his eyes on the crowd, and said loudly:

“Students, brothers and sisters, most of you should be joining my research group for the first time, right?”

Everyone in the audience nodded.

Xu Yun said again:

“Since this is the first time for everyone to cooperate, I don’t have too high requirements for the degree of running-in, but I hope you can keep in mind one thing.”

“That is, you can raise objections or even question my thinking in private, but in the operation stage, you must strictly follow my plan.”

“Any questions related to the experimental plan can only be discussed after taking off the lab coat.”

Xu Yun’s tone was unusually harsh, after all, it involved a very important concept:

Team execution.

In science experiments, team execution is a very critical part.

For example, in Xu Yun’s previous life, he encountered a situation where the experiment failed due to team members’ hesitation:

At that time, he participated in a joint research project between Jinmen and HKUST, which was studying the chiral characteristics of certain leptons.

During the experiment, there are several links that need to change the imposed conditions according to the real-time situation.

There is a step in the process, which is to apply a high-density electric field.

At that time, the entire scientific community did not understand the characteristics of the double helix tetrahedron structure, so the person in charge of the experiment discovered that the preset electric field strength was not enough when the field was approaching.

So he decided to immediately apply an electric field that was more than four times the original amount.

As a result, the operator of the electric field at that time expressed objection and repeated confirmation several times. In the end, he missed the best time to apply the electric field. The experiment funding of more than 4,000 yuan was instantly scrapped because of this mistake.

Although four thousand yuan does not seem to be a lot of funds, in fact, for many project teams, this is already a very high expenditure.

Having learned from the past, Xu Yun naturally would not allow this to happen in his research group.

These project members are almost the same age as him, so they must have some doubts or even slander against Xu Yun in their hearts.

So Xu Yun can only let go of this harsh words first, put himself at the highest point, and then slowly use his ability to conquer them.

After emphasizing the discipline issue.

Xu Yun talked about some other things, and then asked everyone to take their positions and get ready.

Officially start the project research.

The first research project of the research group is very clear, which is how to make the isolated point particles form a stable ground state as mentioned before.

This is also the basis for all subsequent research.

Therefore, Lu Chaoyang did not separate from Xu Yun immediately, but assisted him in tinkering with related equipment.

The “Eye of the World” experimental cabin can be regarded as a mini version of the second-generation light source accelerator, equipped with ion guns, pre-accelerators, calorimeters, back-end electronic components and other instruments.

The entire experimental cabin looks a bit like a nuclear magnetic resonance device, but the underground coil is much larger.

Considering that no one has written the specific process of colliding particles at the starting point, but there are many children’s boots who are interested, here is a relatively simple related science popularization.

Generally speaking.

There are three main types of particles in the collider:

are protons, electrons, and heavy ions, respectively.

The production method of proton is very simple, it can be obtained by ionizing hydrogen gas.

Electronics is a bit more complicated, and there are also three main processes:

Thermal emission—for example, if you burn LaB6 red, electrons can be released when an electric field is applied).

Field emission—add a high field, and electrons can be emitted from the tip of the needle.

And light emission—that is, electrons are emitted by laser light, the photoelectric effect.

Because the laser is easy to control, it can produce short bunches of 10^-12s level and improve the brightness.

If it is an electron beam device that requires polarization—such as the future ILC (International Linear Collider) or EIC (Electron-Proton Collider), then a special crystal is required:

Gallium Arsenide.

When a circularly polarized laser hits this crystal, electrons with the same spin direction can be produced.

Positrons are generally generated by electron targeting:

After the electron flow with a certain energy bombards the target, high-intensity bremsstrahlung will be generated, and the radiation will excite positrons at the same time.

Then just accelerate under the action of the electric field.

The last particle is the heavy ion, and it is also a particle that is heavily used in the collider.

For example, the Hadron Collider requires heavy ions with a high charge state.

Heavy ions are generally produced by first ionizing atoms, accelerating, and then stripping the inner electrons of atoms.

Then, plasma is generated under the action of high electric field in the ion gun.

The heavy ions are drawn out by the electric field, and after being accelerated by the pre-accelerator, the electron flow bombards the carbon film or the gas strips the inner electrons.

Finally, these heavy ions are put into the main accelerator for acceleration and the process is completed.

As long as you have hands.JPG.

What Xu Yun and the others used this time was lead ions.

The acceleration line of the “Eye of the World” experimental cabin is much shorter than that of the main laboratory of synchrotron radiation, but since the trajectory of the lone particle is already known—or the probability, it does not need such a long line for acceleration in practice. .

After everyone settled down.

soon.

A young man sitting in front of the monitoring screen raised his hand and said:

“Dr. Xu, the beam pipeline has been prepared.”

Xu Yun followed the trend and looked.

As the monitoring screen is an important part of the whole experiment, it is naturally impossible for him to casually arrange for strangers to be in charge. The somewhat handsome young man who raised his hand at this time is called Liang Haoran, a fellow student of Xu Yun, who is currently studying in the third year of research. .

However, Liang Haoran did not call himself a senior brother at this time, but formally called Xu Yun’s degree, looking like a passerby.

Xu Yun nodded slightly towards him, as a greeting:

“What is the distance between two adjacent bundles?”

Liang Haoran clicked on the keyboard a few times:

“About 75 nanoseconds.”

Xu Yun stroked his chin and quickly calculated in his mind.

75 nanoseconds multiplied by the speed of light, the final answer is about 22.5 meters.

That is, when the clusters are completely filled, there will be a lead ion cluster every 22.5 meters.

This spacing distance is perfect.

Then Xu Yun asked again:

“What about the total number of particles?”

“Probably more than 200 billion.”

Hearing the number ‘more than 200 billion’, the expressions of everyone present did not fluctuate much.

after all

This number is so normal in particle physics.

For example, take the European collider LHC as an example.

The LHC has two beam channels, each with an average of about 250 trillion particles.

Every four hours, particle collisions in the LHC consume one-tenth of the energy.

So when the LHC is running, the beam needs to be replenished every ten or twenty hours.

no way.

Microcosm is like this.

Some values or magnitudes that sound outrageous are extremely normal in the microscopic field.

Another example.

Neutrinos.

Neutrinos are very penetrating and dense, about 100 per cubic centimeter, which is half the size of your thumb—seems to be normal here, right?

Then add another premise:

Neutrino’s motion speed is close to the speed of light, 300,000 km/s, that is, 30 billion cm/s.

So every 30 billionths of a second, 100 neutrinos pass through your thumb.

In other words.

In 1 second, 3 trillion neutrinos pass through your thumb.

If you spread this volume to your whole body, the magnitude will be 10^16 power.

Later generations of Xu Yun once read a saying that the author is the bus Yunyun, but in fact, in front of neutrinos, the reader is also the bus.

This is the microscopic physics, the mysterious and attractive ‘Abyss’.

All right.

The topic returns to reality.

After getting relevant data from Liang Haoran.

Xu Yun pondered for a moment, then waved his hand:

“Then turn it on!”

The voice fell.

Not far away, a female doctor who was responsible for the calibration of the vacuum tunnel put her **** and index finger together, and gently slid across the temple, and made a salute very sassyly:

“Decree!”

buzz buzz —

With the start-up of the equipment, the atmosphere in the laboratory gradually became serious.

Various values were reported from the crowd following observation or calculation.

“Lb1 value 13638.28!”

“K position calibration, reporting points are T, T, T, F, T, T, T!” (T is true, F is False)

“The design index has reached the 21st power level of 10!”

“Jinxi, report the brightness!”

“Wait a minute, the computer is still calculating. It came out, 10 to the 28th power!”

“Place!”

Whoosh—

In a tunnel invisible to the naked eye.

Thick streams of thick jets jetted out from the long black and hard tube, rushed in both directions, and finally completed the collision at a super-high speed.

Snapped-

With the collision of lead ions.

Countless finer particles exploded, and the image in the electronic cloud room became clearer and clearer.

at the same time.

The energy of the exploded particles is quickly deposited in the calorimeter, and electrons appear as the final product of the collision, which is read by the back-end electronic components and converted into electrical signals to enter the next processing stage.

The boy responsible for reading the back-end electronic components is called Lin Zixu. He is a thin and small boy, wearing a pair of gold-rimmed glasses.

Since the experiment started, he has been nervously paying attention to the digital display screen in front of him.

da~

I saw a reminder sounded.

The indication of a certain energy level suddenly began to stretch upwards like an upside-down A-share index.

See this scenario.

Lin Zixu pulled off the earphones and said to Xu Yun:

“Dr. Xu, we have observed a large number of energy remnants of isolated point particles, and the orbital probability you calculated is at least 80%!”

Xu Yun’s expression didn’t change much upon hearing this.

That formula is a halo product after all. Although the derivation process is somewhat difficult, the accuracy after deciphering is still very high.

Then he was silent for a moment, took a deep breath, and ordered:

“Then begin.”

“Go to the magneto-optical trap.”

Note:

I vomited, I said that I would start adding updates today, and I was notified that the old book would be greatly revised. I glanced at at least 50,000 to 60,000 words.

The good news is that this book is temporarily safe, well, for the time being, the flag will not be set
