Chapter 1392 Your model is wrong
When Peng Juexian took a car from the consulate to the Cardasser Research Center, the rising sun in Provence had slowly risen under the indigo sky.
He lowered the car window and let the morning breeze with the salty and damp Mediterranean smell into the collar, finally barely dispelling the strong sleepiness.
Fang Jianming, who was sitting on the other side of the aisle, turned his head and looked at Peng Juexian who was yawning, and asked worriedly: "Academician Peng, there is about an hour and a half before the meeting begins. Do you want to find a room in the venue to rest?"
As the head of the delegation, Peng Juexian almost never checked his eyes after receiving the report the day before yesterday.
Considering that it is destined to be a very stressful confrontation later, Fang Jianming inevitably began to worry about the other party's physical condition.
"The materials given by Academician Chang are a bit obscure. I have to take advantage of the time before the meeting to start, otherwise the audience may not be able to understand it in a short time..."
Peng Jue shook his head first, and then asked in a half-joking tone: "What, I'm worried that I'll doze off when I'm in the meeting later?"
Although I tried my best to hide the tired face on my face, I could still hear my voice a little hoarse. "That won't... it's mainly because you're worried that you won't have the energy to talk to the masses later." Fang Jianming also changed into a relatively relaxed tone.
"Don't worry."
Peng Jue smiled first:
"In the current agenda, we are the second one to come to power after France, which is equivalent to directly confronting Robert Hull... It is estimated that after the report of the two of us, the delegations of various countries will have to compete for a while, so even if there is a link of verbal battles against the masses of scholars, it is impossible to be today."
After saying that, he lowered his head and glanced at the briefcase placed on his leg.
The document sent by Chang Haonan to him was lying inside at this moment, like a nuclear bomb about to be detonated. "By the way, Lao Fang." After a few seconds of silence, perhaps in order to keep awake through the busyness of facial muscles, Peng Juexian took the initiative to speak:
"When the meeting is held today, remember to arrange a position for Huang Zhitao."
The EU is considered a whole when signing the formal agreement, but it is each fighting each other when it is held. Therefore, the entire meeting includes delegations from more than a dozen countries, and the number of people allowed to enter each meeting is limited.
Except for several key roles, other members can only take turns to participate.
When Huang Zhitao is the last member of the list, even if he is Peng Juexian's student, he would not have been arranged to such an important occasion at the beginning.
So, Fang Jianming, who heard this request, was stunned for a moment:
"Xiao Huang's contribution this time is indeed very great, so he should pay attention to it... but the list was confirmed in advance, so it is difficult for others to delete it..."
For a moment, he was even considering whether the other party was hinting at whether he wanted to kick him out.
But after thinking about it, I feel that the possibility is not high.
Actually, the relationship between the two is very good, and there has never been any unpleasant things.
Secondly, the only three of them are still informed of the matter of temporarily taking out the second edition of the speech...
In fact, Peng Juexian was a little sleepy, and his brain's multi-threading ability was a bit disconnected. He was reminded to react: "Or let him be responsible for the meeting minutes... The meeting secretary does not need to be particularly professional, and he is considered an administrative staff member of the delegation and will not care about taking two extra days off..." Fang Jianming originally wanted to say that the secretary also needed a certain shorthand ability, but after thinking about it, the focus today should be Robert Hull and Peng Juexian. The Japanese delegation ranked third behind may not be able to speak, so there should be no problem.
"Okay, I'll arrange it..."
...
...
One and a half hours later.
In the melodious marches of the ritual, representatives from all countries entered one after another.
The Japanese delegation surrounded Director Morita of Tokyo Quantum Institute and walked quickly through the side door, and even deliberately avoided direct communication with the French delegation.
The Americans were talking in a low voice with the Russian representative, while Dr. Kim Ki-min from the South Korean team nodded to Peng Juexian from afar...
"Teacher Fang, if you don't have time to type the symbols, can you write them on paper first?"
Huang Zhitao hugged in the second row of the Chinese delegation with his laptop in his arms, his fingers unconsciously typing on the keyboard, and his eyes shifted from the glowing ITER logo on the dome of the main conference hall to the two leaders in the front row -
Although he has been wondering for the past two days whether his previous performance could gain extraordinary favor.
But I still didn't expect that I could jump from the delegation's little transparent and academic locust to be placed in such an important position.
After a moment, I was even at a loss.
Fang Jianming turned his head helplessly and explained:
"We will remember the technical and theoretical parts. What you need to do is to record the reactions and themes of the delegations of various countries, and leave them to the archives after returning to China to prevent them from becoming useful in the future. As for the content of the report on the stage, it will be almost the same... But if you say it, it's okay to add a summary, and exercise your ability to extract key information by yourself, which will be useful for independent research in the future."
In fact, this statement is enough to show the importance Huang Zhitao is now receiving.
However, he himself was still in a state of ignorance while being surprised...
Internal meetings did not require so many politeness. After only a simple opening and report session, Robert Hull, as the host representative, took the lead in stepping onto the podium.
"First of all, I will report to you the research progress of the ITER plan so far..."
The French academician's tie was a little tilted than yesterday, and the projector's beam just illuminated the blue and black circle at the moment. Obviously, he hadn't had much rest these days. When the PPT flips to the red bar chart of "plasma maintenance time bottleneck", Peng Juexian noticed that Yasuhiro Morita, who was diagonally opposite, sat upright slightly.
".After three months of continuous experiments, we confirmed that when the maintenance time exceeds the key threshold of 500-550 seconds, the core disturbance amplitude will increase exponentially. "
Hull clicks the mouse, and a 3D animation simulated by the monitoring data begins to play.
The blue plasma looks like the sea surface in a storm. The previous second looks calm, but it has regular ups and downs, but the next second suddenly bursts into spider-web-like cracks from the core, and in a short time that the entire plasma breaks outward.
At the same time, the readings of the peripheral sensors exploded, indicating that energy and particles are erupting from the inside to the outside.
"We have changed the time node of large-scale jagged collapse through some means, but with the current hardware facilities, it is basically believed that the bottleneck of 580 seconds cannot be exceeded..."
Hull pointed to the oscillation curve on the figure and said:
"This is also one of the core motivations for ToreSupra to upgrade the WEST project."
A depressing commotion suddenly sounded in the audience.
Although the serrated oscillation was first observed as early as 1974, since then, the plasma collapse that may be caused by intensified oscillation has become a concern in fusion research in various countries.
But due to the stable operating time or plasma scale, most facilities have not yet had similar experiences.

The conclusions given by the French through experiments are obviously much more serious than everyone's estimates before.
Dr. White from the US delegation suddenly raised his hand: "So the plasma required for 500 seconds in the first phase of the ITER target is based on your data to maintain a conservative estimate?"
"Not this." Hull shook his head and switched to the next slide: "When the 500-second indicator was set in 1998, the running time of ToreSupra had only exceeded the 350-second mark, so it was a complete coincidence..."
The following discussion became obviously noisier.
As mentioned earlier, countries value the help that existing research facilities in Europe can provide more than the long-lasting ITER reactor body.
The ToreSupra problem may not necessarily be solved by a simple upgrade...
Hull deliberately let the tension on the scene ferment for a while before turning the subject and speaking again:
"However, you don't need to worry too much about the progress of WEST's upgrade. We have combined the operating data of ToreSupra with the most authoritative partial magnetic reconnection model at present, and combined with the theoretical support of our Japanese colleagues, we have determined the two parts that have the greatest impact on serrated behavior, namely auxiliary heating and neutral particle beam injection."
"As we all know, the tooth collapse is caused by the trigger of the M=1 mode, so a macro-driven related to the effective potential energy function is first needed..."
"..."
"..."
"
Next, he spent about 40 minutes to explain the quasi-exchange mode instability under the incomplete magnetic reconnection model, and finally mentioned the principle of controlling serrated oscillation: "The above stability threshold can be used to analyze the tooth control through fast ion, neutral beam injection or thermonuclear reaction and various current drives. With sufficient operating data, as long as the position of the q=1 plane is accurately measured, the position of the neutron beam injection can be accurately positioned and the most suitable plasma preheating temperature is found..."
"..."
After all the main contents were said, Hull paused for a while to facilitate the audience to understand and digest.
Of course, even if most of the participants are veteran researchers, it is impossible to judge whether the content he said is correct or not. At most, there is only time to sort out a relatively smooth logic.
And at least in engineering, this logic is impeccable. "I know that accurately measuring the position of the q=1 side is not easy, and neutral beam injection also requires a large external power input, but at least it provides a theoretical way to completely solve the risk of plasma collapse." Hull pressed the laser pointer and the red arrow pierced the equipment structure diagram just shown on the curtain: "So, WEST will focus on upgrading the neutral beam injection and low-mixed wave heating system, and it is expected that the maintenance time will be increased to about 800 seconds within two years..." After his report, the entire conference room was headed by the Japanese delegation.
Not to mention anything else, the plan to increase the maintenance time by 60% within two years is also worthy of this treatment.
Even Fang Jianming and Peng Juexian slapped a few times—
They knew that the goal of the French should be achieved.
But because of the mistake of the theoretical starting point, it does not have greater potential...
With Hull's pearls and jade in front, when Peng Jue came on stage first, the reaction in the venue had become much colder.
It’s not that I have any opinions on Peng Juexian himself or the Chinese delegation.
It’s really a lot of passion that has been consumed just now, and now it needs to be buffered.
After all, although China's Oriental Super Circle is progressing rapidly, it still doesn't look so dazzling compared to the old ToreSupra and JT60U.
What's more, it's the upgraded WEST.
However, the first two sentences of Peng Juexian appearing on stage directly changed the atmosphere of the entire meeting.
"Dear dear delegates and Academician Robert Hull, the theme of my report today also happens to be related to the phenomenon of jagged tooth collapse."
"We have found sufficient theoretical basis to prove that the partial magnetic reconnection model used to describe jagged oscillation in the past 10 years is not mechanism-complete!"
