Chapter 1391: Tie the Chains of Europe
In fact, when Peng Juexian led his team to France, Chang Haonan had already returned to Huairou Science City and began to prepare for new hypersonic weapons tests and theoretical tests of dual-modal ramjet engines.
Han Chenfeng continues to be mainly responsible for the research and testing of nuclear batteries.
So, the satellite communication request issued by the former was transferred several times before finally contacting Chang Haonan, who had just started working in China. "Old Peng, this time... it should be two o'clock in the morning in France?"
Chang Haonan looked at the time in the lower right corner of the computer screen, and at the same time took the thermos cup full of hot tea from Xing Muchun: "What, the negotiations on ITER have made a breakthrough?" "The seminar will not start until the day after tomorrow... Oh, it should be considered that it will start tomorrow, and the negotiations will be further backward." Peng Juexian's voice mixed with a rustling current sound: "But you are right, we have made some breakthroughs off the court."
A sound of paper flipping vaguely sounded in the background: "In today's open forum, there were some problems with the plasma waveform data released by the French. We couldn't take a photo in the specific situation, but in short, we suspected that the ToreSupra device encountered a sawtooth collapse. Although there was no evidence, it was highly likely to be accompanied by abnormal changes in the topology of the magnetic field... I am transmitting the relevant information, and you will receive it soon." "I'm sure it was a chain instability caused by the collapse of the magnetic topology?" "Chang Haonan stopped sliding the mouse: "In addition, has the Dongfang Superring ever encountered similar situations? I mean, using our data to compare, can we specifically determine how serious the ToreSupra problem is?" "
Peng Juexian immediately denied: "I haven't encountered it... or strictly speaking, I haven't had time to encounter it yet. The current magnetofluid stability time of the Oriental Super Ring is still in the order of magnitude around 200 seconds. Even if there are hidden dangers, the jagged tooth oscillation still has no time to develop into a large-scale jagged tooth collapse, so it can only be speculated at present."
"However, one of my doctoral students found that the coordinate axis on the PPT was deliberately compressed, and the actual amplitude was at least one order of magnitude larger than the displayed value... If there is no problem, they can just take a normal picture, and there is no need to do it too much. "
Perhaps because it was too late, Peng Juexian's speech speed was a little faster than usual: "And if their superconducting magnet system has magnetofluid oscillation of this order, upgrading WEST will only drag the problem to the new device... But Robert Hull just declared at the meeting that 'there is a solution'."
Chang Haonan held the receiver and fell into deep thought.
The cost of encrypted satellite communications when providing services to the outside world is calculated in seconds, but as the promoter of the construction of the Qingluan constellation, he naturally doesn't have to care too much about these.
After a while, I spoke again:
"Do you think the French claimed solution may be problematic?"
"That's right, but this is not the point..."
Peng Juexian replied:
"The key point is that I think the French want to use the model of the Tokyo Institute of Quantum Science and Technology to explain the serrated collapse. In exchange, the priority of the ITER test cycle will be tilted towards them... and now there are signs that they may participate in the upgrade plan of the Japanese JT60SA test reactor."
Chang Haonan raised his eyebrows:
"Didn't you say before that there would be no Japanese participation in the first test cycle?"
There was a sigh from the other end of the phone:
"It was before, now now... If the status quo is maintained, it would be difficult for us to stop this situation from happening on our own. After all, the EU has undertaken nearly half of the total ITER funding, and the French have the highest voice..."
"Of course, I also asked indirectly with my acquaintances here. The other party revealed to me privately that Tokyo's theory is based entirely on the 'ideal assumption' of numerical simulation, but there is no other choice at the moment, so the proposition proposed by Hull on behalf of the French Academy of Sciences is currently mainstream."
At this point, Chang Haonan probably also heard some clues.
The French are probably not monolithic, but the current opinions on Japan's cooperation dominate.
This situation is very familiar to him.
When we negotiated aviation industry cooperation with the EU, the situation was almost the same:
"So, do you think we can solve it, or at least explain this problem theoretically?"
Peng Juexian was silent for two seconds:
"First of all, we need to determine whether the magnetic field structure distortion we observed in Factory 504 before corresponds to the problems encountered by ToreSupra... Current theory generally believes that serration collapse and abnormal changes in the magnetic field topology are independent companion phenomena. If..."
At this time, Chang Haonan had already opened the materials sent by the other party on the computer and continued the conversation:
"If we can prove that there is a relationship between the two, our advantages will be very obvious, which can at least offset or even surpass Tokyo's advantages in theoretical research..."
"That's right." Peng Juexian replied. "Then... give me some time." After Chang Haonan said that, he hung up the phone directly.
After saying that, he quickly listed a series of criterion equations for the collapse of sawtooth on paper, and then opened the phone number of the Torch Laboratory: "Yabo, help me deal with a partial differential equation..."
...
Peng Juexian didn't sleep all night until dawn, and closed his eyes in a daze.
But before I could fully fall asleep, I was awakened by the prompt sound of the satellite communication.
"The model is true."
Chang Haonan's voice was dull, as if he was talking about something that had been expected:
"When the frequency ratio of the circumferential magnetic field to the pole magnetic field is close to a rational number, the spiral wave will trigger chain resonance in the plasma core... This just explains why the boundary local mode burst suddenly appeared in the experimental data released by JT-60U last year..."

Peng Juexian slapped the sofa armrest with a bang:
"Okay!"
"This is not a matter of homesickness. I can write a specific proof process for you."
Chang Haonan's response was very straightforward.
However, Peng Juexian did not respond immediately.
Because he knew that the other party must have something to say later.
Sure enough, after a mouse click, Chang Haonan spoke again: "But what I want is not just academic victory. If we can prove our level in the field of plasma steady state research, what specific benefits can we get?"
Peng Juexian has been thinking about this question for most of the day and gave the answer without thinking:
"At least the first two cycles of test priority, and it can squeeze out the first cycle plan from Tokyo, and then extend the test period by one third... In addition, no less than two-thirds of the time allocated to my country will be used for the lithium/oxygen vacancy research that you are interested in, Academician Chang."
Such conditions, both for the Chinese delegation and for Chang Haonan personally, it is already a stable profit.
But the principle he has always adhered to is that if you make less, you will lose.
"It's okay from my personal perspective. Two-thirds of the cycle should be enough to get large-scale test data... But Lao Peng, I think you can also make some other requests."
Peng Jue has heard of Chang Haonan's ability to quarrel.
So a new interest came in an instant:
"What do you say?"
"Since the ToreSupra team plans to cooperate with Tokyo, I'm afraid there will be some considerations of using JT60 as a guinea pig... Then they should choose some Japanese subsystems as future upgrade components?"
"As usual, it should be."
Peng Juexian was a little uncertain:
"But what specific parts are there, this will have to be announced later, and even if it is a good example, there must be a bidding process..."
However, Chang Haonan was indifferent tone: "It doesn't matter. You can adapt to the situation at that time. In short, you should try your best to get some parts development tasks for us. It may not necessarily be very core, but it must require subsequent operation and maintenance, or at least it requires continuous supply of consumables, such as filters, ion heating equipment, superconducting magnet systems..." "In this way, even if there is no follow-up in the ITER project in the future, the operation of WEST equipment will still be inseparable from our support!"
