Chapter 441: Thirty Minutes
At the same time that Lu Zhou made a difficult choice, a plane landed at the airport in Luyang, Huaguo, on the other side of the earth.
After returning from a visit to the Spiral Stone 7-X laboratory in Germany, Sheng Xianfu did not stop after getting off the plane. He took the car on the Huanhu Avenue and went straight to the Institute of Physical Science on Science Island.
Seeing Professor Sheng rushing to the institute in a hurry, and Ren Yong who happened to be in the corridor, he took a surprise look at him.
"What's the rush?"
Professor Sheng would answer, and only said one sentence.
"thirty minutes."
Ren Yong was slightly stunned, at first he didn't understand what he said, but he quickly realized that he couldn't believe it.
"Thirty minutes? They... really did it?"
Professor Sheng nodded and said seriously.
"In fact, they almost failed at first, and the cooling effect of the water-cooled divertor did not meet expectations. But the paper published on PRX recently helped them, and they succeeded in reducing the heat load of the first wall material by improving the control scheme. Although the distance There may be a gap of a few seconds in 30 minutes, but these small errors can be ignored."
Although the stellarator is a very novel research idea, there are still disputes in the academic circles about whether it can really achieve the theoretically expected effect.
Because even though the stellarator can be designed to confine the plasma more easily than the Maktok, the excessive heat load caused by the long-term pulse discharge is still an open problem in nuclear fusion engineering.
But if Helix 7-X can really achieve 30-minute long-time pulse discharge, perhaps this will change the entire pattern of international nuclear fusion engineering.
After all, the tokmak device has been researched so far. The deeper you go, the closer you can feel the ceiling. More and more people are beginning to reflect on whether this research idea is feasible.
"Just because of a paper?"
Staring blankly at Professor Sheng, Ren Yong's face was full of disbelief.
To not underestimate the usefulness of theoretical work.
It's just that the speed at which this theory is transformed into results is too fast, right? !
After a while, he put on a serious tone and said, "Which one? I'll go and have a look."
"The latest issue of PRX is the paper by Lu Zhou. As for the paper of the Max Planck Society, it is on the official website of the IAEA-Demo International Symposium, and it should be up now. You will know after reading it."
After leaving this sentence, Professor Sheng didn't stop, and continued to walk upstairs with meteoric strides.
There are only two things he has to do now.
The first thing is to report the results of this academic visit to the organization.
The second thing is to report the importance of this talent to the organization.
No matter what price was offered, he had to find a way to invite him back.
Others may not understand the importance of that paper, but he does.
Glancing at Professor Sheng's back, Ren Yong didn't stay in the corridor, but turned and returned to his office.
He turned on his laptop and found the papers recommended by Professor Sheng from the database. After downloading them, he read them line by line.
Although he didn't fully understand it, he still understood it in general.
To put it simply, Professor Lu established a theoretical model for plasma turbulence in the stellarator, and then the Institute of Plasma Physics of the Max Planck Society rewritten the control algorithm based on his theoretical model. Through a more precise control scheme, Reduces the detachment of particles striking the first wall material from the ribbon plasma, thereby reducing the heating of the first wall material…
After roughly scanning the papers on the screen, Ren Yong leaned back on the office chair, stared at the screen and said thoughtfully.
"...Is he more optimistic about stellarator?"
In fact, Huaguo is not without research on stellarator.
In the early 1970s, under the influence of the Americans, the 585 Institute tried to design a stellarator named "Lingyun", but limited by the conditions of the times, this project did not proceed in the end.
After all, the Americans couldn't do it anymore, they changed the stellarator C into a Tokmak ST, and began to learn the technical route of the T3 device developed by the Soviets.
Later, tokamak gradually became the mainstream choice of research institutions in various countries. In order to concentrate limited efforts to achieve major events, and considering the influence of Big Brother, relevant domestic scientific research institutions finally chose tokamak as a technical route.
However, times are always changing. Fifty years ago it was one thing, fifty years later it will be another. Although the tokmak has achieved good results, the most critical pulse discharge time has fallen into a bottleneck.
After gradually realizing this problem, Huaguo is also restarting stellarator-related projects recently, such as the H1-Heliac stellarator delivered from the Australian National University to Huaguo Nanhua University, and then to Xinan Jiaotong University and Japan's nuclear fusion science Huaguo's first quasi-circular symmetric stellarator jointly built by the institute...
However, even if the stellarator research is restarted, the mainstream choice of domestic scientific research institutions, mainly the Chinese Academy of Sciences, for the controllable nuclear fusion technology route is still concentrated on the tokmak.
After all, there is no such thing as bids and answers in scientific research. A healthy scientific research environment can only be where all kinds of research ideas can flourish.
For a scholar, it is more important than anything else to stick to one's own research ideas and continue to do so.
As for who is right, who has been wrong.
That is a matter for history to judge.
At this time, Liu Changle, who was drinking tea at the desk next to him, glanced at his screen: "What kind of paper is this? Why are there so many formulas that I have never seen before?"
"Written by Professor Lu," Ren Yong smiled, "It's normal not to understand, and I can only understand the abstract."
"Professor Lu?" Liu Changle froze for a moment, frowned and thought for a while, but he didn't think of anyone in the plasma physics circle in China who had the surname Lu.
Ren Yong: "Lu Zhou from Princeton, who else could it be?"
Hearing this name, Liu Changle was stunned.
Of course Lu Zhou knew.
But this man...
"He's a math guy, but he also understands nuclear fusion?"
Hearing this, Ren Yong was immediately happy.
"He is the technical consultant of the He-3 project team of PPPL laboratory, and it is even rumored that he is the actual person in charge of the project. Not to mention this paper, he has established a mathematical model for the problem of plasma turbulence. In this field, if even him None of them have the right to speak, so I am afraid that only the plasma in the reactor has more right to speak."
Liu Changle's expression changed.
"He-3 atom probe technology?"
He may not know what kind of work Lu Zhou has done, but it is impossible for him not to have heard of the He-3 atom probe technology that has caused a sensation in the industry.
Leaving aside, let’s just talk about the experimental reactor on their Science Island. Recently, they are designing a similar He-3 particle launcher, which is going to be used to observe the macroscopic and microscopic parameters of the high-temperature and high-pressure plasma inside the reactor.
Theoretically, this stuff can be used in stellarators, tokmak devices, and even in addition to nuclear fusion engineering, it can be used in many researches involving plasma.
Relevant papers can be downloaded from ITER's conference proceedings and many literature databases, which are considered public information, and there is no secret at all.
Contrary to the world imagined by the public, in reality, the entire nuclear fusion project can be called confidential, but in fact, only the laser ignition technology involved in the nuclear test...
Looking at this colleague, Ren Yong said speechlessly, "How long has it been since you paid attention to the trends in the academic world?"
Liu Changle coughed dryly and changed the topic.
"You said that if the Chinese Academy of Sciences invites this great god back someday, will we all be driven to accompany him in tinkering with stellarators?"
Ren Yong: "Come on, you've already said that you are a great god. Others think highly of our small temple? No matter whether we can invite them back, they won't be able to come to us at that time."
Liu Changle frowned and said, "Where else can we go if we don't come here?"
After all, it is "future science". There are only a few domestic research institutes engaged in controllable nuclear fusion. If you don't go to the Chinese Academy of Sciences, why not go to Xi'an Jiaotong University?
The temple is even smaller.
Ren Yong said with a smile: "Build another research institute, how simple it is."
