Just as Lu Zhou was making a difficult choice, a plane landed at the airport in Luyang, Huaguo, far away on the other side of the world.

After returning from the visit and exchange of the Spiral Stone 7-X Laboratory in Germany, Sheng Xianfu got off the plane without stopping, took the car on Huanhu Avenue, and went straight to the Institute of Physical Science on Science Island.

Seeing Professor Sheng rushing to the research institute in a hurry, Ren Yong, who happened to be in the corridor, glanced at him unexpectedly.

"What's the matter?"

Professor Sheng will answer, only one sentence.

"Thirty minutes."

Ren Yong was slightly stunned, he didn't understand what he said at first, but he quickly reacted and couldn't believe it.

"Thirty minutes? They...... Did you really do it? ”

Professor Sheng nodded and said seriously.

"In fact, they almost failed at first, and the cooling effect of the water-cooled deflector did not meet expectations. But a recent paper published in PRX helped them by improving the control scheme and they were able to reduce the heat load on the first wall material. While there may be a difference of a few seconds from 30 minutes, these small errors are negligible. ”

Although the stellar mimic is a very novel research idea, there is still controversy in the academic community about whether it can really achieve the expected effect in theory.

Because even though stellarellars can be designed to confine plasma more easily than Maktok, the excessive heat load caused by long-term pulsed discharges is still an open problem in fusion engineering.

But if the Spiral 7-X can really achieve a long-term pulse discharge of 30 minutes, perhaps this will change the pattern of the entire international nuclear fusion project.

After all, the more you go deeper into the Maktok installation, 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?"

Looking at Professor Sheng in a daze, Ren Yong's face was full of disbelief.

to not belittle 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 changed his serious tone and said, "Which one?" I'll take a look. ”

"The latest issue of PRX, Lu Zhou's one. As for the Max Planck Society's paper, it is on the official website of the IAEA-Demo International Symposium, and it should be hanging up by now, you can find out when you go to see it. ”

Throwing down this sentence, Professor Sheng did not stop, and continued to stride upstairs.

There are only two things he has to do now.

The first is to report to the organization on the results of this academic visit.

The second thing is to report to the organization the importance of this talent.

No matter what price is offered, you have to find a way to get him back.

Others may not understand the importance of that paper, but he does.

Glancing at Professor Sheng's back, Ren Yong didn't stop in the corridor, and turned around and returned to his office.

I opened my laptop and found the papers recommended by Professor Sheng from the database, and after downloading them, he read them line by line.

Although he didn't fully understand it, he generally understood.

To put it simply, Professor Lu built a theoretical model for the phenomenon of plasma turbulence in stellaratorstellars, and then the Max Planck Institute's Institute of Plasma Physics rewrote the control algorithm for his theoretical model, and through a more precise control scheme, the particles that break away from the ribbon plasma and hit the first wall material are reduced, thereby reducing the heating of the first wall material......

After a cursory scan of the paper on the screen, Ren Yong leaned back in his office chair and said thoughtfully as he stared at the screen.

“…… Is he more optimistic about stellarstellar? ”

In fact, Huaguo is not without research on stellarumers.

As early as the early 70s, under the influence of the Americans, the 585 Institute tried to design a stellar simulator called "Lingyun", but due to the conditions of the times, this project did not go on in the end.

After all, the Americans couldn't do it themselves, so they changed the star simulator C to the Tokmak ST, and began to learn the technical route of the T3 device from the Soviets.

In order to concentrate limited forces to accomplish great things, and considering the influence of Big Brother, relevant domestic scientific research units finally chose Tokmak as the technical route.

However, times are always changing, fifty years ago it was the same, fifty years later it will be another. Although Tokmak has been achieving good results, the most critical pulse discharge time has reached a bottleneck.

After gradually realizing this problem, Huaguo has recently restarted stellarator-related projects, such as the H1-Heliac stellaratom delivered from the Australian National University to Huaguo Nanhua University, and then to the first quasi-ring symmetrical stellarumer jointly built by Xinan Jiaotong University and the Japan Institute of Nuclear Fusion Science......

However, even if the research on stellarators is restarted, the mainstream choice of controlled nuclear fusion technology routes by domestic scientific research institutions, mainly the Chinese Academy of Sciences, is still focused on tokmac.

After all, there is no such thing as a standard answer in scientific research, and a healthy scientific research environment is when various research ideas can flourish.

For a scholar, it is more important than anything else to stick to his own research ideas and continue to do it.

As for who is right and who is wrong.

That's all for history to judge.

At this time, Liu Changle, who was sitting at the desk next to him drinking tea, glanced at his screen: "What kind of paper is this?" Why are there so many formulas that I haven't seen before. ”

"Professor Lu wrote," Ren Yong smiled, "It's normal not to understand, and I can only understand the abstract." ”

"Professor Lu?" Liu Changle was slightly stunned, frowned and thought for a while, but he didn't come up with a big bull surnamed Lu in the domestic plasma physics community.

Ren Yong: "Princeton's Lu Zhou, otherwise who else could it be?" ”

Hearing this name, Liu Changle was stunned.

Lu Zhou, of course he knew.

But this man ......

"He's a math guy and he knows about nuclear fusion?"

As soon as he heard this, Ren Yong was immediately happy.

"He is a technical advisor to the He-3 project team of PPPL Laboratories, and there are even rumors that he is the de facto leader of the project. Not to mention this paper, where he built a mathematical model for the plasma turbulence problem. If he doesn't have a say in this area, then only the plasma in the reactor has a say. ”

Liu Changle's face changed.

"He-3 atomic probe technology?"

He may not know what work Lu Zhou has done, but he can't have heard of the He-3 atomic probe technology that has caused a sensation in the industry.

Not to mention, the experimental reactor on their science island has recently been designing a similar He-3 particle launch gun, which is ready to be used to observe the macro and micro parameters of the high-temperature pressure plasma inside the reactor.

Theoretically, this thing is used in the stellarumer, in the tokmak device, and even in addition to nuclear fusion engineering, many studies involving plasma can be used.

The papers are available in ITER's conference proceedings and in many bibliographic databases, and are considered public information, and there are no secrets to speak of.

Contrary to the world of public fantasy, in reality, the entire nuclear fusion project can be called classified only by laser ignition technology related to nuclear tests......

Looking at this colleague, Ren Yong said speechlessly: "How long have you not paid attention to the trends in the academic world?" ”

Liu Changle coughed dryly and diverted the topic.

"You said that if the Chinese Academy of Sciences invited this great god back one day, would we all be driven to accompany him to tinker with the stellar mimic thing?"

Ren Yong: "Come on, you say it's a great god, and others can afford our little temple?" Regardless of whether they can be invited back or not, it will not be possible to come to us at that time. ”

Liu Changle frowned and said, "If you don't come to us, where else can you go?" ”

After all, it is "future science", and there are only a few research units engaged in controlled nuclear fusion in China.

The temple was even smaller.

Ren Yong said with a smile: "It's a simple matter to build another research institute." ”
