Chapter 1391 The Chain 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-mode ramming engines.


    Han Chenfeng continues to be mainly responsible for the research and testing of nuclear batteries.


    Therefore, 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, right?"


    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:


    "Why, ITER''s negotiations 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 back."


    Peng Juexian''s voice mixed with a rustling current sound came:


    "But you''re right, we made some breakthroughs off the field."


    A vague sound of paper flipping in the background:


    "In today''s open forum, there are some problems with the plasma waveform data released by the French. We cannot take photos in the specific situation, but in short, we suspect that the ToreSupra device has encountered a sawtooth collapse, and although there is no evidence, it is 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."


    "Is it a chain of instability caused by the collapse of the magnetic topology?"


    Chang Haonan stopped sliding the mouse:


    "In addition, have Dongfang Super Ring encountered similar situations? I mean, using our data to compare, can we specifically determine how serious the problem with ToreSupra is?"


    Peng Juexian immediately denied:


    "I haven''t encountered it before... or strictly speaking, I haven''t had time to encounter it yet. The current magnetic fluid stability time of the Oriental Super Ring is still in the order of 200 seconds. Even if there are hidden dangers, the serrated oscillation still has no time to develop into a large-scale serrated collapse, so it can only be speculated at the moment."


    "However, one of my doctoral students found that the coordinate axes on the PPT were deliberately compressed, and the actual amplitude was at least an order of magnitude larger than the displayed value... If there was no problem, they could just take a normal picture, and there was no need to do anything extra."


    Perhaps because it was already late, Peng Juexian''s speech speed was a little faster than usual:


    “And if their superconducting magnet system has already had magnetofluid oscillation of this order, upgrading WEST will only drag the problem to the new device…but Robert Hull just declared at the meeting ‘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:


    "You think the French claimed solution might be problematic?"


    "That''s right, but that''s not the point..."


    Peng Jue first replied:


    "The point is that I think the French are trying to explain the serrated collapse with the model from the Tokyo Institute of Quantum Science and Technology, and in exchange, priority of the ITER test cycle will be tilted towards them... and now there are signs that they may be involved in the upgrade plan of the Japan JT60SA test reactor."


    Chang Haonan raised his eyebrows:


    "Didn''t you say before that there will be no Japanese participation in the first test cycle?"


    A sigh came from the other end of the phone:


    "It was before, now it is now... If the status quo is maintained, it may be difficult for us to stop this situation by relying on our own efforts. After all, the EU has undertaken nearly half of the total ITER funding, and the French have the highest voice among them..."


    "Of course, I also asked indirectly with an acquaintance here. The other party revealed to me privately that the theory in Tokyo is entirely based on the ''ideal assumption'' of numerical simulation, but there is no other choice at the moment, so the claim made by Hull on behalf of the French Academy of Sciences is currently mainstream."


    Now that things have come to this point, Chang Haonan probably also heard some clues.


    The French are probably not monolithic, but the opinions on Japan''s cooperation are currently dominant.


    And 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 take action to 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 phenomenon we observed in Factory 504 can correspond to the problems encountered by ToreSupra... The current theory generally believes that serrated 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.


    "So…give me some time."


    After Chang Haonan finished speaking, he hung up the phone directly.


    After saying that, he quickly listed a series of criterion equations for jagged teeth on paper, and then opened the phone number of Torch Laboratory:


    "Yabo, help me deal with a partial differential equation..."


    …


    Peng Juexian didn''t sleep all night until dawn, and he closed his eyes in a daze.


    But before he could fall asleep, he was awakened by the prompt sound of the satellite communication.


    “The model holds.”


    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..."


    The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!


    Peng Juexian slapped the sofa armrest with a bang:


    "good!"


    "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 homeostasis 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 hesitation:


    "The test priority for at least the first two cycles can be squeezed out the first cycle plan, 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."


    With such conditions, both for the Chinese delegation and Chang Haonan personally have been considered a sure profit and no loss.


    But the principles he has always adhered to are—


    If you make less, you will lose.


    "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 by the way."


    Peng Jue had heard of Chang Haonan''s ability to quarrel.


    So a new interest came in an instant:


    "How to say it?"


    "Since the ToreSupra team plans to cooperate with Tokyo, I''m afraid it''s also considered using JT60 as a guinea pig... Then should they choose some Japanese subsystems as upgrade components in the future?"


    "As usual, that''s what it should be."


    Peng Juexian was a little uncertain:


    "But what specific parts are there, this will not be announced until later. And even if you look like it, there will always be a bidding process..."


    However, Chang Haonan had an 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 information on the ITER project in the future, the operation of WEST equipment is still inseparable from our support!"
