Scholar’s Advanced Technological System

When the manuscript drifted across Haiti to Professor Kreiber's mailbox, a serious meeting was taking place in the conference room of the Spiral Stone 7-x laboratory.

Sitting here are big cattle like Professor Ganser Heissinger, director of the Institute of Plasma Physics of the Max Planck Institute, as well as heads from the Helmholtz Federation, as well as from the ppp1 laboratory, the ), Visiting scholars of iter project participants, such as Institute of Plasma Physics, Chinese Academy of Sciences.

If Professor Lazersson did not resign from ppp1, the person sitting here at this moment should also have him. Due to the increasingly important role of the he-3 atom probe technology in plasma observation, the status of the "he3 project team" has also risen to a higher level.

But now, it's not Lazerson who sits here, but his assistant Laverne Boucher, a doctor in his thirties. Sitting next to a group of big guys, the newcomer looked a little cramped and didn't dare to speak at the meeting.

As for why the conference atmosphere is so serious ...

We have to start from last month.

Just last month, the spiral stone 7-x finally completed the installation of the water-cooled diverter.

According to the plan of the Institute of Plasma Physics of the Max Planck Institute, the water-cooled deflector will completely solve the problem of the temperature of the reaction chamber.

However, the results were not as ideal as expected.

The plasma heated to a temperature of 100 million degrees is indeed confined within the electromagnetic field, and the water-cooled deflector does play a role, but the degree of temperature increase of the first wall still exceeds the expectations of the field staff.

With the accumulation of a large amount of thermal energy that is too late, the temperature of the first wall material continues to rise, and it gradually begins to threaten the safety of the stellar orbit.

In order to avoid major safety accidents, staff had to shut down the equipment and terminated the test early.

In the end, after the installation of the water-cooled deflector, the constraint of the high-temperature pressure plasma was maintained for only 6 minutes.

Compared to the more than a hundred seconds of the Tokemark installation in the international mainstream research direction, this result is already quite outstanding.

But for the stellar, this achievement is undoubtedly a failure.

Looking at the research report in his hand, Kreiber faced the experts and scholars at the conference table and made a short report.

"... the water-cooled diverter has been installed, but now the problem is that the confinement of the plasma is not as perfect as we think."

"... According to the feedback data, starting from 227 seconds, a small amount of unbound plasma comes into contact with the first wall as the main cause of heat accumulation, which eventually leads to the accumulation of heat on the material of the first wall beyond the cooling of the water-cooled divertor Efficiency is also beyond our expectations. "

After listening to Kreiber's report, Professor Urdall from the Helmholtz Federation suddenly spoke.

"Do you mean, the problem is not with the water-cooled divertor, but with the plasma in the stellar out of control?"

Although the Spiral 7-x laboratory is a research facility at the Institute of Plasma Physics of the Max Planck Society, the entire research facility including this stellar is jointly constructed by the Max Planck Institute and the Helmholtz Federation of Germany. .

As the second largest scientific research organization in Germany after the Max Planck Institute, the Helmholtz Federation is still quite powerful in the field of fusion energy.

"It's not out of control, it's the natural dispersion of the plasma. Even a star can't make every plasma orbit around it. There will always be so many plasmas hit the first wall, and this is "Acceptable error," Kleiber emphasised when questioning from the Helmholtz Federation.

Professor Odor raised his eyebrows: "Just a few?"

Kreiber: "... This is just a metaphor. Of course I can't give you a specific quantity. I can only tell you that at least compared to mainstream Marktork devices, we have done a lot on magnetic confinement. Excellent. "

Seeing that the two were about to quarrel, Professor Heissinger coughed lightly, interrupting the argument between the two.

"The problem is clear, and now what we need to do is solve the problem, not continue to argue on meaningless things."

After a pause, Professor Heissinger continued.

"We now have two options, one is to change the existing control scheme, and the other is to change our cooling system."

Either reduce the plasma on the first wall by more precise electromagnetic field control, or change to a more powerful water-cooled diverter to improve cooling performance.

"I'm afraid it will be difficult to improve the existing control scheme," Professor Kreiber shook his head. "If there are better control schemes that can be replaced, we have already used them."

Boucher, who had not had a chance to speak, tried to interject: "What about replacing the water-cooled diverter?"

"This is unrealistic, even if it is based on the existing basis, it is impossible." Professor Heissinger shook his head: "The point of the problem now is that we have to cash in on the 30 we made before 2o2o Minutes promise ... and we only have two years at most. "

The atmosphere in the conference room was a bit heavy, and no one spoke.

As Professor Heisinger said, time is the key.

Water-cooled diverting filters are not refrigerators. This millimeter or even micron-level project has a high degree of difficulty in each step. It is not easy to reassemble, let alone redesign the device.

From 15 years to now, it took them three full years to install the current water-cooled deflector on the spiral stone 7-x.

Now there are only two years left between 2o2o years, and they have no time to spend another three years to redesign and assemble the water-cooled diverter.

To be honest, it is foolish to set a specific time for science.

Even if it is the most authoritative person in a certain field, it is impossible to predict in advance how long a certain technology will take to make.

It may be born tomorrow, or it may be fundamentally wrong.

But if they do n’t do this and do n’t continue drawing this piece of cake, no one will invest money in them ...

...

At 12 o'clock, the meeting was temporarily dissolved and arrangements were made to continue after 2 pm.

Sitting in the restaurant on the first floor of the laboratory, Kreiber ordered a cup of coffee, sat by the window, opened his laptop for work, and habitually logged in to the mailbox to glance at unread mail.

"Review invitation?"

Looking at the e-mail lying in the mailbox, Kreiber raised his eyebrows with interest.

Strictly speaking, he is not a plasma physicist, but an engineer in the field of plasma physics and fusion energy.

In addition, compared with the mainstream Tokemark device, the stellar device is a "cold" research direction, and there are not many international research institutions engaged in this field.

An invitation to review the journal of the American Physical Society, he remembered the last time or five years ago.

Originally, it was not intended to take the break between meetings for review, but Kreiber couldn't hold back the curiosity in his heart and opened the paper.

Although he is not a plasma physicist, he has worked in the Institute of Plasma Physics of the Max Planck Society for a long time, and he is not unfamiliar with theoretical things. He still has reviewing ability and qualifications.

Mathematical model of plasma turbulence?

Seeing the abstract of the dissertation, Professor Kreiber raised his eyebrows.

Phenomenological model?

But it seems a bit different.

After reading the abstract, Professor Kleiber continued to look at the main text. When he saw the large formula in the thesis ~ www.readwn.com ~ his eyebrows twitched suddenly.

As an engineer, knowledge of mathematics is indispensable. However, these calculations in the thesis are still out of the scope of his knowledge reserve, watching him numb.

Speaking of it, it is just to build a phenomenological model. Do you need to use such a profound mathematical method?

While Professor Kreiber was confused by this matter, this descriptive language could save the "style" of the province, and suddenly reminded him of a person.

Going directly to the position of the author of the paper, Kreber's mouth was also pulled down with his eyebrows.

It really is this guy ...

With a smile, he shook his head and completely gave up Kreiber, skipping the complicated calculations directly, and looked at the mathematical model of the conclusion part.

He acknowledged that he did disagree at first.

Gradually, the more he looked down, the more solemn the look on his face.

Suddenly, a flash of joy flashed on his face, and he couldn't wait to reach out the phone in his pocket.

"Iger, in a while I will email you to your mailbox and print out the papers for me!"

Iger is his office assistant. He usually gives chores such as schedules and seals to him.

In principle, a paper that has not been formally published is not good for publication in advance, but it is not a violation of the principle if it is only for internal communication.

After all, for many reviewers, it is not uncommon to exchange opinions with peers who have a good academic reputation if they see particularly outstanding manuscripts that happen to involve areas they do not understand.

Iger: "Okay sir, can you tell me how many copies you need?"

"Print as many copies as there are people in the afternoon meeting!"
