Scholar’s Advanced Technological System

Shangjing City.

In the studio of tv "The Road to Science", a program about controlled nuclear fusion is going on.

"Welcome everyone to watch the road of science in this period, I am the host Cheng Nan."

“In film and television works or literary works on science fiction, we can always see a description of controlled nuclear fusion. The word “controllable nuclear fusion” also seems to condense all our fantasies about energy...”

"The theme of this program is the future energy-controlled nuclear fusion that makes us fascinated."

"To this end, we specially invited the director of the China National Nuclear Fusion Energy Program Executive Center and the chief engineer, Academician Zhou Chengfu of the Southwest Institute of Physics to explain the past and present life of the controllable nuclear fusion... Welcome!"

Hey!

Driven by the host, the audience at the scene encouraged a round of applause.

From the behind-the-scenes of the studio, the two white-faced Zhou Chengfu nodded to the audience with a smile, and then sat on the sofa at the invitation of the host.

These days, he was in a meeting in Beijing, just in time to meet the invitation of the "Science Road" column group. Since he was not very busy recently, he came over and made a turn.

Although scientists and actors are different and do not need exposure, it is necessary for them to be interviewed appropriately for researchers engaged in future disciplines.

After all, spending so much money, they have to let the public know what they have done and what their research results can change.

“The audience may have heard of it. Just a few months ago, the star-studded star device in Jinling City successfully completed the ignition experiment. Counting this imitation star, including magnetically constrained ht -7 and east tokamak devices, as well as the inertial restraint of the gods, and the recently proposed reverse field pinch, our national researchers have almost all the technical routes of controlled nuclear fusion research, walking in The forefront of the world."

"Before the star installation, our country's research on the imitation star is almost blank. I would like to ask Zhou Academician, what do you think about this first domestic satellite device?"

Upon hearing this question, Zhou Chengfu smiled and said modestly: "It is too exaggerated to say that the ignition is very expensive. After solving the two problems of stagnation and plasma irradiation on the first wall material, we generally They are all experimenting with hydrogen."

Moderator: "Do you know about the star device?"

Zhou Chengfu smiled faintly: "There is not much to understand, but it is still understood."

Moderator: "That can ask you to talk to us, what are the features of this star device?"

Upon hearing this question, Zhou Chengfu opened his mouth and said a little.

"To say the characteristics, as you said, it is probably the first imitation star in the true sense of the country."

"As for its prototype, you may not have heard of it, but I can tell you that it is actually a German wega device. This device was probably retired from 2013 and has been stored in Frankfurt, Germany. Later, Professor Lu When I went to Germany to study, I probably just took a fancy, so I lobbied in the two countries and spent 500 million euros on research funding to buy it from the Germans."

The host’s face showed a surprised expression: “500 million euros? It’s nearly 4 billion in exchange for rmb... Is the research on controlled nuclear fusion burning money?”

The audience also showed strange expressions.

4 billion!

Poverty limits their imagination.

Zhou Chengfu smiled and didn't feel much about the number he said.

"It depends on what you compare with, and it is definitely more expensive than studying mathematics, but it is a bit cheaper than the Space Station and Hadron Collider."

Of course, it is not so good to say how much this point is.

Moderator: "Then you think that after the Nirvana rebirth, the star device can copy the 30-minute miracle created by the spiral stone 7-x?"

It seems that he is not very satisfied with the word Nirvana rebirth. Zhou Chengfu frowned and frowned, but soon realized that it was on the show, so the brow stretched out in a flash.

“30 minutes?” Shaking his head with a smile, Zhou Chengfu said with a light wind, “It’s not easy to run for two minutes in a row.”

The host looked at Zhou Chengfu with amazement and continued to ask: "Are you not optimistic about this star device?"

Upon hearing this question, Zhou Chengfu said: "It is not a problem that I can't look good. The reason why the spiral stone 7-x can complete the 30-minute long-time plasma constraint is mainly due to its special external field coil design. And the most critical water-cooled divertor."

"This water-cooled divertor, although there are also on the wega device, but it is something more than twenty years ago, it is still too far worse than the one that is currently serving on the spiral stone. If the star imitation star is going to copy the spiral stone 7 The success of -x, he had to at least make innovations on the cooling device, but obviously he did not."

This is not because he said that the success of the spiral stone in the 30-minute long-term restraint is mainly due to the contribution of the water-cooled divertor, at least to the Germans.

The newly designed water-cooled divertor will naturally not appear on the wega device.

What's more, even if you don't look at these factors, it is almost two months since the scientific review article came out. Until now, the Star Imitation Institute has not had any movements.

Now Zhou Chengfu can basically decide, not that Lu Zhou does not want to use the facts to refute him, but the star device can't do it at all.

It is precisely because of this, when he said this sentence, he has no pressure.

"... At present, the mainstream of internationally controlled fusion research is still the Tokamak, and then the inertia constraint of laser ignition, and the inverse field pinch that you have just mentioned."

"In theory, every technical route can be made. As long as we solve the problems we face on this route and the problems we are about to face, the final destination is ultimately the fusion we are pursuing. Energy. Just like pickup trucks and cars, they are all four wheels. As long as they pass the toll booth, they can go on high speed."

It was amused by the metaphor of this image, and the audience at the scene showed a smile.

After a pause, Zhou Chengfu continued.

“The imitation star is too difficult in engineering. In contrast, Tokamak’s design is more succinct and the difficulty in engineering is relatively low.”

“We don’t have to try every technical route. Instead of trying every possibility, it’s better to focus limited resources on the most likely directions.”

"This is a pragmatic choice compared to a random attempt without rules!"

......

After the interview, I recalled the applause in the previous studio. Zhou Chengfu, who left the studio, was relaxed and only felt happy in the mood.

Although the speech on this popular science program did not have much substantive effect, but in the thought that the bird did not bird his young man, his heart was a relief.

Just then, the phone in his pocket suddenly rang.

When I touched the mobile phone, I saw that Jia Liang was only called, so he pressed the button that was connected and put the phone in his ear.

"Hey?"

"Week, Director Zhou!"

"What?" Zhou Chengfu frowned at the flustered voice.

"It's a star research institute!"

Zhou Chengfu said impatiently: "You give me a word to finish the words, what happened to the star research institute."

"Just yesterday, they restarted the experiment!"

Upon hearing this sentence, Zhou Chengcheng Fu was in a tight heart and hurriedly asked.

"They restarted the experiment? I haven't heard anything about it? Tell me, what is the result of his experiment? Is it 30 minutes?"

Listening to the general problem of this cannon, Jia Liangcai showed a bitter smile on his face.

"It’s not thirty minutes..."

It was not thirty minutes to hear, Zhou Chengfu breathed a sigh of relief.

However, his tone has not been loosened to half, and he is destined to be unable to come out.

Jia Liangcai at the end of the phone continued to speak with a bitter and unbelievable tone.

"...I saw the report in the Jinling Daily. They seem to have magnetically constrained time for an hour..."
