Great Country Academician

According to the original plan, after the Helix-7X was transported from the Planck Institute of Plasma, it was officially renamed the ‘Huaxing Fusion Device’.

This is China's first stellarator.

Although it was purchased from someone else, it also filled a gap in the field of star-simulating devices in China.

With the personnel and equipment in place, the research plan on the small-scale controllable nuclear fusion project has officially entered the next stage, officially switching from the tokamak device to the stellarator route.

For Xu Chuan, after having completed the magnetic confinement controllable fusion technology, he does not have many projects that require personal research on the re-ignition and fusion of stellarators.

The disadvantages of the stellarator are that it is very difficult to manufacture and the internal plasma temperature is low, making it difficult to achieve ignition and fusion.

But for China, this is not something difficult to solve.

The former can rely on a complete industrialization system and huge manpower and material resources for processing. With the mobilization of red-headed documents, I believe that no country can compete with China for efficiency.

The solution to the latter lies in improved superconducting materials and plasma turbulence numerical control models.

With the help of the powerful critical magnetic field of the improved superconductor material, the binding force can be effectively increased. The strength of the outer magnetic field can greatly reduce the 'neoclassical transmission' effect of the stellarator and maintain the thermal effect.

The so-called 'neoclassical transmission' effect refers to the fact that in a toroidal device, the magnetic field on the inside of the torus is stronger than the outside. The curvature and gradient of the magnetic field can cause the plasma to drift, resulting in particle loss and heat loss.

To put it simply, if the entire fusion device is compared to a heat source, the tokamak device naturally has the advantage of thermal insulation, and its structure can maintain and reduce the heat loss of this 'heat source'.

The stellarator is at a disadvantage in this regard.

Because the stellarator is based on an extremely complex magnet configuration drawn by artificial intelligence, its magnetic field has much greater ripples than a tokamak.

Although it can control the plasma more effectively and maintain the flow for a long time.

But these designs and construction will result in neoclassical transport levels and high-energy particle loss levels higher than those of tokamak.

More heat is lost, and a large amount of fusion energy leaks out of the reactor chamber.

Just like a vehicle driving on a highway, the Tokamak device is like a highway in Qilu, a wide and straight area where you can drive at will.

The stellarator is like a mountain road in Qiangui, with many twists and turns.

In these two situations, it is self-evident which road is more likely to cause a car accident.

The improved superconductor is like widening the mountain road in Guizhou and Guizhou, and the CNC model of high-temperature plasma turbulence is like adding navigation and intelligent control systems to the vehicle.

Of course, this is just a simple metaphor. In fact, the operation of high-temperature plasma in a fusion reactor is far more complicated than this.

But overall, they do have enough strength to re-take the fusion ignition route on the stellarator.

Therefore, he who has led the team through this road once has no need to stay at Xinghai Research Institute and personally direct the work.

With the successful ignition of the Dawn Fusion Reactor, Xu Chuan is quite confident in the successful ignition of the Huaxing Fusion Reactor to complete the fusion technology.

Even if this time he would not devote himself to taking charge of the overall situation in the institute, but would allocate all the work, he still has enough confidence.

He believes that the Xinghai Research Institute, which was transformed from the Qixia Controlled Nuclear Fusion Project, has sufficient capabilities to independently complete the assembly and debugging of the ‘Huaxing Fusion Device’.

What he wants to do is to solve the problems that arise during the miniaturization process after the Huaxing device achieves fusion ignition.

As for now, it's not time for him to be busy yet.

Of course, another benefit of this is to cultivate talents.

At his level, sometimes what needs to be considered is not only the success of the project, but also the accumulation of relevant talents during the research process of the project.

After all, a country is made up of countless people, and a large-scale project cannot be supported by one person.

Although he led the team to complete the research and development of controllable nuclear fusion technology, subsequent optimization, expansion, updates and other aspects require a large number of talents to complete.

And now is the best time to cultivate.

After spending a few days at the Xinghai Research Institute and assigning work related to the Huaxing Fusion Reactor, Xu Chuan returned to Nanda.

In the mid-spring season, the sun is shining brightly and all kinds of flowers are in bloom, turning the formerly green campus into a colorful layer.

"Professor, the report on miniaturized and controllable nuclear fusion that you asked me to pay attention to has been reported by the "Nuclear Industry Times" and "Hua Xin News" today."

In the office, Tang Ran held two newspapers in his hands, put them on the desk, and said softly.

Hearing this, Xu Chuan was stunned for a moment, and then quickly realized what Tang Ran was talking about.

Mainly because it took so long that he almost forgot about it.

"Well, thanks, I'll take a look first."

Xu Chuan smiled, thanked him, and picked up the newspaper from the table.

On the page, the report on miniaturized and controllable nuclear fusion occupies a small arc, just like a normal nuclear industry media interview and news.

Looking through it, there is not a lot of content. It mainly contains some regular interview news of Liang Qu, as well as some non-confidential things such as the follow-up research work of Xinghai Research Institute.

However, a small detail worth noting is that the miniaturized tokamak device, that is, the picture of the fusion reactor of about five meters, was released.

Under normal circumstances, without permission, it is impossible for such photos involving core technologies to pass review, even if it is just an appearance.

But now that it has been released, it undoubtedly increases its credibility.

After flipping through the newspaper, a smile appeared on Xu Chuan's lips.

Now it's his turn.

Putting down the newspaper in his hand, Xu Chuan opened arxiv and submitted the manuscript he had prepared.

At the same time, he clicked on his email and found the email of the editor of PRX (Physical Reviews X). He attached the relevant papers and manuscripts to the email and sent it out.

I have to say that when the email was sent, he felt a sense of "refreshment" about doing bad things secretly.

Although there is nothing wrong with the paper he wrote, all plans and routes are based on the results that Xinghai Research Institute has already produced, and there is no falsehood at all.

But this paper is quite misleading to be honest.

He is not very clear as to which countries will be affected, but there is no doubt that the United States will be the first.

There is no other, because the United States itself has a compact small-scale nuclear fusion research device - the 'Alcatel C-Mod Compact Fusion Reactor'!

I believe he will see news about the restart of this compact fusion reactor soon.
