Egger: “Okay sir, can you tell me approximately how many copies are needed?”
Strictly speaking, he is not a plasma physicist, but an engineer in the field of plasma physics and fusion energy.
In the end, after the installation of the water-cooled divertor was completed, the constraint of high-temperature and high-pressure plasma in the stellarator only lasted 6 minutes.
Looking at the email lying in the mailbox, Kleiber raised his eyebrows with interest.
However, gradually, the further he looked down, the more serious the expression on his face became.
"Invitation to review?"
Sitting here are experts like Professor Gunther Heisinger, Director of the Max Planck Institute of Plasma Physics, as well as people in charge sent by the Helmholtz Association, as well as people from the PPPL Laboratory and the International Atomic Energy Agency (IEAR). ), the Institute of Plasma Physics of the Chinese Academy of Sciences and other ITER project participants.
After all, for many reviewers, if they see a particularly outstanding manuscript that happens to involve a field they do not understand, it is not uncommon to exchange opinions with peers with a good academic reputation.
Originally, according to the plan of the Max Planck Institute of Plasma Physics, the water-cooled divertor would completely solve the problem of reaction chamber temperature.
But now, the person sitting here is not Razelson, but his assistant Laverne Bushell, a doctor in his thirties. Sitting next to a group of big guys, the newcomer looked a little embarrassed and didn't dare to speak much at the meeting.
"The problem has been very clear. What we need to do now is to solve the problem instead of continuing to argue over meaningless things."
"We now have two options, one is to change the existing control scheme or one is to change our cooling system."
In addition, compared with the mainstream Tokomak device, stellarator is considered an "unpopular" research direction, and there are not many research institutions engaged in this field in the world.

If Professor Razelson had not resigned from PPPL, he would be among the people sitting here at this moment. As He-3 atom probe technology plays an increasingly important role in plasma observation, the status of the "He3 project team" has also risen.
Just last month, Helixite 7-X finally completed the installation of the water-cooled divertor.
Kleiber, who smiled and shook his head, gave up completely, skipped the complicated calculations, and looked at the mathematical model in the conclusion.
Ige is his office assistant, and he leaves general scheduling, printing and other chores to this person.

Sure enough, it's this guy...
However, gradually, the further he looked down, the more serious the expression on his face became.
As for why the atmosphere in the meeting was so serious...
"Print me as many copies as there are people in the afternoon meeting!"
From 2015 to now, it took them three full years to install the current water-cooled divertor on the Spiral Stone 7-X.
Ige is his office assistant, and he leaves general scheduling, printing and other chores to this person.

Kleiber, who smiled and shook his head, gave up completely, skipped the complicated calculations, and looked at the mathematical model in the conclusion.
"This is unrealistic. Even if it is modified on the existing basis, it is impossible." Professor Heisinger shook his head: "The key to the problem now is that we have to fulfill the 30 goals we have made before 2020." Minute commitment...and we only have two years at most.”
Either reduce the plasma on the first wall through more precise electromagnetic field control, or replace it with a stronger water-cooled divertor to improve cooling performance.
Bushell, who never had a chance to speak, tried to interject: "What about replacing the water-cooled divertor?"
We have to start from last month.
The water-cooled divertor is not a refrigerator. This kind of millimeter or even micron-level project is extremely difficult at every step. It is not easy to reassemble it, let alone redesign the device.
"Ege, I will send an email to your mailbox in a moment and print out the paper in it for me!"
"It's not out of control, it's the natural divergence of plasma. Even a star can't make every plasma run around the orbit in an orderly manner. There will always be a few plasmas that hit the first wall, and this is Acceptable error." In response to the question from the Helmholtz Association, Kleiber emphasized.
Sitting in the restaurant on the first floor of the laboratory, Kleiber ordered a cup of coffee, sat by the window, opened his work laptop, and habitually logged into his mailbox and looked at his unread emails.
It could be born tomorrow, or it could be fundamentally wrong.
In principle, papers that have not yet been officially published cannot be made public in advance, but if it is only for internal communication, it does not violate the principle.

Just last month, Helixite 7-X finally completed the installation of the water-cooled divertor.
We have to start from last month.
After all, for many reviewers, if they see a particularly outstanding manuscript that happens to involve a field they do not understand, it is not uncommon to exchange opinions with peers with a good academic reputation.
Suddenly, a joyful look flashed across his face, and he couldn't wait to take out the phone in his pocket.
Originally, according to the plan of the Max Planck Institute of Plasma Physics, the water-cooled divertor would completely solve the problem of reaction chamber temperature.
He turned directly to the author of the paper, and the corners of Creber's mouth twitched along with his eyebrows.
After reading the abstract, Professor Kleiber continued to look at the text. When he saw the large formulas in the paper, his brows suddenly twitched.
As the second largest scientific research organization in Germany after the Max Planck Society, the Helmholtz Association still has a considerable say in the field of fusion energy.
If Professor Razelson had not resigned from PPPL, he would be among the people sitting here at this moment. As He-3 atom probe technology plays an increasingly important role in plasma observation, the status of the "He3 project team" has also risen.
But it seems a little different.
Although the Helix 7-X Laboratory is a research facility of the Max Planck Institute of Plasma Physics, the entire research facility, including this stellarator, was jointly built by the Max Planck Society and the German Helmholtz Association. .
As the second largest scientific research organization in Germany after the Max Planck Society, the Helmholtz Association still has a considerable say in the field of fusion energy.
However, the results were not as ideal as expected.
"You mean the problem is not the water-cooled divertor, but the plasma in the stellarator is out of control?"
As for why the atmosphere in the meeting was so serious...
When the time reached 12 o'clock, the meeting was temporarily disbanded and arranged to continue after 2 o'clock in the afternoon.
When the manuscript was sent to Professor Kleiber's mailbox across the ocean, a very serious meeting was taking place in the conference room of the Spiral Stone 7-X Laboratory.
He admits that he was a little unimpressed at first.
After a pause, Professor Heisinger continued.
When the manuscript was sent to Professor Kleiber's mailbox across the ocean, a very serious meeting was taking place in the conference room of the Spiral Stone 7-X Laboratory.
Professor Erdore raised his eyebrows: "Just a few?"
The plasma heated to a high temperature of 100 million degrees was indeed confined within the electromagnetic field, and the water-cooled divertor did play its role, but the temperature of the first wall increased faster than the on-site staff expected.
"... The water-cooled divertor has been installed, but the problem now is that the plasma confinement is not as perfect as we imagined."
Suddenly, a joyful look flashed across his face, and he couldn't wait to take out the phone in his pocket.

"I'm afraid it will be difficult to improve the existing control scheme," Professor Kreber shook his head. "If there were a better control scheme that could be substituted, we would have used it long ago."
As a large amount of heat energy is accumulated that has no time to dissipate, the temperature of the first wall material continues to rise, gradually beginning to threaten the safety of the stellarator orbit.
"...According to the feedback data, starting from 227 seconds, a small amount of unbound plasma came into contact with the first wall and became the main cause of heat accumulation. Eventually, the accumulation rate of heat on the first wall material exceeded the cooling efficiency of the water-cooled divertor. , and exceeded our expectations.”

He turned directly to the author of the paper, and the corners of Creber's mouth twitched along with his eyebrows.
In order to avoid major safety accidents, the staff had to turn off the equipment and terminate the test early.
After a pause, Professor Heisinger continued.
To be honest, putting a specific date on science is a silly thing to do.
As Professor Heisinger said, time is of the essence.
Looking at the research report in his hand, Kleiber faced the experts and scholars at the conference table and made a brief report.
We have to start from last month.
The water-cooled divertor is not a refrigerator. This kind of millimeter or even micron-level project is extremely difficult at every step. It is not easy to reassemble it, let alone redesign the device.

But if they don’t do that, if they don’t continue to draw this piece of pie, no one will invest money in them...
In addition, compared with the mainstream Tokomak device, stellarator is considered an "unpopular" research direction, and there are not many research institutions engaged in this field in the world.
Sitting in the restaurant on the first floor of the laboratory, Kleiber ordered a cup of coffee, sat by the window, opened his work laptop, and habitually logged into his mailbox and looked at his unread emails.

Ige is his office assistant, and he leaves general scheduling, printing and other chores to this person.
Suddenly, a joyful look flashed across his face, and he couldn't wait to take out the phone in his pocket.
Compared with the more than 100 seconds of the Tokmak device in the international mainstream research direction, this result is already quite outstanding.
After listening to Kleiber's report, Professor Erdoll from the Helmholtz Association suddenly spoke.
Seeing that the two were about to quarrel, Professor Heisinger coughed slightly and interrupted their argument.

"We now have two options, one is to change the existing control scheme or one is to change our cooling system."
Looking at the email lying in the mailbox, Kleiber raised his eyebrows with interest.
However, gradually, the further he looked down, the more serious the expression on his face became.
In principle, papers that have not yet been officially published cannot be made public in advance, but if it is only for internal communication, it does not violate the principle.
In the end, after the installation of the water-cooled divertor was completed, the constraint of high-temperature and high-pressure plasma in the stellarator only lasted 6 minutes.
Looking at the email lying in the mailbox, Kleiber raised his eyebrows with interest.
"I'm afraid it will be difficult to improve the existing control scheme," Professor Kreber shook his head. "If there were a better control scheme that could be substituted, we would have used it long ago."
After reading the abstract, Professor Kleiber continued to look at the text. When he saw the large formulas in the paper, his brows suddenly twitched.
From 2015 to now, it took them three full years to install the current water-cooled divertor on the Spiral Stone 7-X.
Even the most authoritative person in a certain field cannot predict in advance how long it will take to develop a certain technology.
But if they don’t do that, if they don’t continue to draw this piece of pie, no one will invest money in them...

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

"The problem has been very clear. What we need to do now is to solve the problem instead of continuing to argue over meaningless things."
Professor Erdore raised his eyebrows: "Just a few?"

In addition, compared with the mainstream Tokomak device, stellarator is considered an "unpopular" research direction, and there are not many research institutions engaged in this field in the world.
Bushell, who never had a chance to speak, tried to interject: "What about replacing the water-cooled divertor?"
Just last month, Helixite 7-X finally completed the installation of the water-cooled divertor.
Suddenly, a joyful look flashed across his face, and he couldn't wait to take out the phone in his pocket.
But if they don’t do that, if they don’t continue to draw this piece of pie, no one will invest money in them...
Egger: “Okay sir, can you tell me approximately how many copies are needed?”
But now there are only two years left before 2020, and they have no time to spend another three years redesigning and assembling the water-cooled divertor.
Compared with the more than 100 seconds of the Tokmak device in the international mainstream research direction, this result is already quite outstanding.
Originally, he didn't plan to use the break between meetings to review the manuscript, but Kleiber couldn't resist his curiosity and clicked on the paper.
He remembered that the last time he was invited to review for a journal under the American Physical Society was five years ago.
As an engineer, mathematical knowledge is indispensable. However, the calculations in the paper are still beyond the scope of his knowledge reserve, and it makes his scalp numb.
Originally, according to the plan of the Max Planck Institute of Plasma Physics, the water-cooled divertor would completely solve the problem of reaction chamber temperature.

Sure enough, it's this guy...
Ige is his office assistant, and he leaves general scheduling, printing and other chores to this person.
Although he is not a plasma physicist, he has worked at the Max Planck Institute of Plasma Physics for a long time, so he is not unfamiliar with theoretical things. He still has the review ability and qualifications.
Kleiber: "... This is just a metaphor. Of course I can't give you a specific number. I can only tell you that at least compared to the mainstream Maktok device, we have done an excellent job in magnetic confinement. ”
After a pause, Professor Heisinger continued.
Mathematical model of plasma turbulence
To be honest, putting a specific date on science is a silly thing to do.
It could be born tomorrow, or it could be fundamentally wrong.
Sure enough, it's this guy...
The water-cooled divertor is not a refrigerator. This kind of millimeter or even micron-level project is extremely difficult at every step. It is not easy to reassemble it, let alone redesign the device.
In addition, compared with the mainstream Tokomak device, stellarator is considered an "unpopular" research direction, and there are not many research institutions engaged in this field in the world.

But it seems a little different.
Kleiber, who smiled and shook his head, gave up completely, skipped the complicated calculations, and looked at the mathematical model in the conclusion.
He turned directly to the author of the paper, and the corners of Creber's mouth twitched along with his eyebrows.
Phenomenal model

As for why the atmosphere in the meeting was so serious...
After all, for many reviewers, if they see a particularly outstanding manuscript that happens to involve a field they do not understand, it is not uncommon to exchange opinions with peers with a good academic reputation.
But it seems a little different.
In order to avoid major safety accidents, the staff had to turn off the equipment and terminate the test early.
In principle, papers that have not yet been officially published cannot be made public in advance, but if it is only for internal communication, it does not violate the principle.
Speaking of which, it's just a phenomenological model. Do you need to use such profound mathematical methods
After reading the abstract, Professor Kleiber continued to look at the text. When he saw the large formulas in the paper, his brows suddenly twitched.
We have to start from last month.
In the end, after the installation of the water-cooled divertor was completed, the constraint of high-temperature and high-pressure plasma in the stellarator only lasted 6 minutes.
As the second largest scientific research organization in Germany after the Max Planck Society, the Helmholtz Association still has a considerable say in the field of fusion energy.

"This is unrealistic. Even if it is modified on the existing basis, it is impossible." Professor Heisinger shook his head: "The key to the problem now is that we have to fulfill the 30 goals we have made before 2020." Minute commitment...and we only have two years at most.”
Mathematical model of plasma turbulence
"Ege, I will send an email to your mailbox in a moment and print out the paper in it for me!"
Either reduce the plasma on the first wall through more precise electromagnetic field control, or replace it with a stronger water-cooled divertor to improve cooling performance.
"It's not out of control, it's the natural divergence of plasma. Even a star can't make every plasma run around the orbit in an orderly manner. There will always be a few plasmas that hit the first wall, and this is Acceptable error." In response to the question from the Helmholtz Association, Kleiber emphasized.
Just when Professor Kleiber was confused about this matter, this "style of writing" that can save descriptive language suddenly reminded him of a person.
Either reduce the plasma on the first wall through more precise electromagnetic field control, or replace it with a stronger water-cooled divertor to improve cooling performance.
The plasma heated to a high temperature of 100 million degrees was indeed confined within the electromagnetic field, and the water-cooled divertor did play its role, but the temperature of the first wall increased faster than the on-site staff expected.

Sitting here are experts like Professor Gunther Heisinger, Director of the Max Planck Institute of Plasma Physics, as well as people in charge sent by the Helmholtz Association, as well as people from the PPPL Laboratory and the International Atomic Energy Agency (IEAR). ), the Institute of Plasma Physics of the Chinese Academy of Sciences and other ITER project participants.

Ige is his office assistant, and he leaves general scheduling, printing and other chores to this person.
If Professor Razelson had not resigned from PPPL, he would be among the people sitting here at this moment. As He-3 atom probe technology plays an increasingly important role in plasma observation, the status of the "He3 project team" has also risen.
Sitting in the restaurant on the first floor of the laboratory, Kleiber ordered a cup of coffee, sat by the window, opened his work laptop, and habitually logged into his mailbox and looked at his unread emails.

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

The water-cooled divertor is not a refrigerator. This kind of millimeter or even micron-level project is extremely difficult at every step. It is not easy to reassemble it, let alone redesign the device.
As a large amount of heat energy is accumulated that has no time to dissipate, the temperature of the first wall material continues to rise, gradually beginning to threaten the safety of the stellarator orbit.
"Print me as many copies as there are people in the afternoon meeting!"
