(Before going to bed at night, I always felt that Chapter 504 was not finished, so I got entangled. After lying in bed, I got up and revised the plot. If you have already subscribed, you can go back and read it again. No new charges will be charged.)

Hearing this question, Xu Chuan smiled, leaned back on his chair, and said, "It is impossible to give up magnetic constraint. It can be said that we have almost no research on the route of inertial constraint."

"And magnetic confinement has now successfully realized fusion power generation. With such advantages, it is impossible for us to give up magnetic confinement and use inertial confinement."

"As for which route to change."

After a pause, he continued: "Of course, whichever route has more advantages in plasma confinement will depend on which one we take."

Hearing this answer, Liang Qu said without hesitation: "If plasma confinement has more advantages, of course it is the stellarator."

In the decades since humans have developed controllable nuclear fusion, magnetic confinement and inertial confinement have been two completely different categories.

Inertial constraints are now negated, and under magnetic constraints, tokamak devices and stellarators were undoubtedly the most promising routes ever.

Of course, the one that can realize the fusion route now is naturally the tokamak device.

After all, the Dawn Fusion Reactor has spoken for itself with facts.

However, when it comes to plasma control advantages, the tokamak device is not the best. Whether it is inertial confinement or the stellarator in the magnetic confinement route, it is better than the tokamak device in constraining high-temperature plasma.

After a slight pause, Liang Qu remembered something, looked at Xu Chuan with some confusion, and asked cautiously: "It's just... wasn't this route something you personally denied?"

When we first studied the Dawn Fusion Device, everyone discussed which specific route to take.

The star-simulator route that this boss personally denied at the beginning is now brought up again and he wants to go back. Does this count as reversing the track?

Hearing this, Xu Chuan smiled and explained: "Yes, when I was studying controllable nuclear fusion, I personally decided on the tokamak route, but I never said that the stellarator would be the way to go. It doesn’t make sense.”

Liang Qu recalled it carefully, and it seemed that this person had never said such a thing.

After thinking for a while, he said: "But the internal temperature of the stellarator is probably difficult to compare with that of the tokamak device? It will be more difficult to achieve ignition."

Xu Chuan nodded and said: "Indeed, this is the disadvantage of the star-simulating device."

“The reason why I initially felt that the tokamak device had more advantages was that the plasma performance in the tokamak device chamber far exceeded that of the stellarator.”

"The tokamak device can easily achieve high plasma temperatures of hundreds of millions, but it is far more difficult for a stellarator to achieve a temperature of hundreds of millions than other magnetic confinement routes."

"You also know very well that for controllable nuclear fusion, what really affects the fusion efficiency is the reaction cross section, which is the probability of collision between positively charged nuclei in the plasma."

"The higher the temperature, the more active the plasma, and the greater the probability of collision between positively charged nuclei. Therefore, after solving various problems, the tokamak device is more suitable for large-scale power generation than the stellarator."

"But when it comes to plasma confinement, among all the magnetic confinement routes, none can compare to the stellarator."

"The external magnetic field of the stellarator is the strongest, and there is no ohmic transformer inside to start the plasma current, and there is no need to consider issues such as twisted membranes, magnetic surface tearing, resistive wall membranes, etc."

"The disadvantages are that on the one hand, engineering and manufacturing are very difficult, and on the other hand, the internal plasma temperature is low, making it difficult to achieve ignition and fusion."

"But there should be ways for us to solve these two points."

Liang Qu thought for a moment and said, "But we don't have a stellarator."

After a slight pause, he added: "Don't talk about us, we don't even have complete stellarator technology in China. As for foreign countries, the only ones studying stellarator are the Germanic countries and the small island countries."

Before the controllable nuclear fusion technology was realized in the Dawn Fusion Reactor, the two main fusion methods taking the magnetic confinement route were tokamak devices and stellarators.

Compared with the internationally mainstream tokamak devices, the influence of stellarators is much smaller.

Before the dawn fusion reactor was realized, there were only two countries that were studying stellarators and had detailed and complete stellarator technology.

One is a Germanic country and the other is a small island country.

Other countries, even the United States, do not have complete technology.

On the one hand, it is too difficult to manufacture stellarators, and on the other hand, the United States mainly studies inertial constraints.

Some other countries, such as Australia, India, South Korea and other countries, although they have star-simulating devices in name, in fact they are basically fake and can only do simple experiments.

As for China, there is indeed no complete stellarator.

Originally, two years ago, Nanhua University finalized cooperation with Australia and planned to introduce Australia's H-1 stellarator in the second half of this year.

But after the Dawn Fusion device was successfully commercialized for ignition and power generation last year, this matter naturally disappeared.

After thinking for a while, Xu Chuan said: "I will figure out a solution to this problem. You can continue to conduct experiments and collect more data."

Liang Qu nodded and said: "Okay, let's continue to conduct experiments step by step and collect data."

Liang Qu left, and Xu Chuan leaned on the back of his chair and stared at the white ceiling again and again.

China does not have a star simulator at all, so it is simply unrealistic to build its own star simulator from beginning to end.

If you start researching and building it from scratch, you don’t know how long it will take.

Even if everything goes well, it is estimated that it will take five or six years. If there are some problems in the middle, the time will start from ten years upwards.

Although the manned spaceflight and lunar exploration projects are far less urgent than the controllable nuclear fusion project, they can be taken slowly.

But spending so much time on this is not worth it to him personally.

After ruling out self-research and development, the only way left is to buy ready-made products from others and then conduct research and transformation.

"I wonder what's going on with the Spiralite-7X at the Planck Institute of Plasma. Is there any chance to buy it back? If not, the predecessor of the Spiralite, WEGA, should be able to buy it, right?"

Staring at the ceiling, Xu Chuan muttered to himself.

The last time he took away the ASDEX device from the Planck Institute of Plasma Research, he transformed it and completed the research and development of controllable nuclear fusion technology.

Although controllable nuclear fusion technology has little to do with the ASDEX device, I don’t know if the Planck Institute for Plasma Research thinks so.

In this case, will the other party still sell?

Or if he sells it, what price will he have to pay?

Forget it, don’t think about it so much, let’s write a letter first.

Shaking his head, Xu Chuan looked away and took out the letter from the drawer.

"On the Feasibility of Stellar Simulators in Controlled Fusion Miniaturization Technology and the Application Prospects of Miniaturized Fusion Reactors"

Regardless of whether he could succeed or not, he had to give it a try first to get some funds.

"Dear"

PS: Yesterday's chapter was not finished. I revised it and then couldn't sleep. I might as well write one more chapter to make up for the last update (one more update left). There are two more updates today. Please vote for me.
