Chapter 515: Not just 30 minutes

phone-reading
Go to Beijing.
In CTV's "Scientific Way" studio, a program about controlled nuclear fusion is ongoing.
"Welcome everyone to watch this edition of Science Road. I am the host Cheng Nan."
"In sci-fi film and television works or literary works, we can always see the description of controlled nuclear fusion. The word controlled nuclear fusion also seems to condense all our fantasy about energy ..."
"The theme of this episode is the future energy that fascinates us-controlled fusion."
"To this end, we specially invited the director and chief engineer of Huaguo International Nuclear Fusion Energy Program Executive Center and academician Zhou Chengfu of Southwestern Institute of Physics to explain to us the past and present of controlled nuclear fusion ... everyone is welcome!"
Papapa-!
Driven by the host, the audience at the scene encouraged warm applause.
From the backstage of the studio to the stage, the two white Zhou Chengfu nodded to the audience with smiles, and then sat on the sofa at the invitation of the host.
In these days, he met in Shanghai, and just happened to be invited by the "Scientific Road" column group. Since he hasn't been busy lately, he came around and took a lap.
Although scientists and actors are not the same and do not need such things as exposure, it is also necessary for them to be interviewed appropriately for researchers in future disciplines.
After all, after spending so much money, they have to let the public know what they have done and what their research results can change.
"The audience present may have heard of it. Just a few months ago, the stellar STAR device located in Jinling City successfully completed the ignition experiment. Counting this stellar, including the magnetically constrained HT Tokamak devices such as -7 and EAST, as well as the inertia-constrained aura, and the recently proposed anti-field pinch, our national researchers have almost covered all the technical routes of controlled nuclear fusion research, To the forefront of the world. "
"Before the STAR installation, our country ’s research on stellar devices was almost blank. I would like to ask Academician Zhou, what is your opinion on the first stellar device in China?"
After hearing this question, Zhou Chengfu smiled and said humbly: "It is said that the ignition is too exaggerated. After all, plutonium is very expensive. Before solving the two problems of plutonium retention and plasma radiation damage to the first wall material, we generally It ’s all experimenting with hydrogen. "
Moderator: "Do you know about STAR installations?"
Zhou Chengfu smiled slightly: "I don't know much, but I still understand it."
Moderator: "Can you please tell us what are the characteristics of this STAR device?"
Hearing this question, Zhou Chengfu opened his mouth slightly, and said.
"If you want to say features, as you said, it is probably the first real imitator in the real sense in China."
"As for the 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 since 2013 and has been stored in Frankfurt, Germany. Professor Lu When I went to Germany to study, I probably saw it, so I lobbied in both countries and bought it from the Germans with 500 million euros in research funding. "
The host's face showed a startled expression: "500 million euros? If you switch to RMB, it will be almost 4 billion ... Is the research on controllable fusion so costly?"
The audience also looked surprised.
4 billion!
Poverty limits their imagination.
Zhou Chengfu smiled, but didn't feel much about the number he said.
"It depends on what you compare with. It must be a lot more expensive than studying mathematics, but it is slightly cheaper than the space station and hadron collider."
Of course, how much this point is, it is not easy to say.
Moderator: "Do you think that after Nirvana's rebirth, the STAR installation can replicate the 30-minute miracle created by Spiral 7-X?"
It seemed that he was not very satisfied with the word Nirvana rebirth. Zhou Chengfu frowned subconsciously, but soon realized that it was in the program, and then his eyebrows stretched out.
"30 minutes?" Shook his head with a smile, Zhou Chengfuyun said lightly, "It's not easy to run for two minutes continuously."
The host looked at Zhou Chengfu with a look of surprise, and continued to ask, "Aren't you optimistic about this STAR device?"
Hearing this question, Zhou Chengfu said bluntly: "It's not a problem I don't think is good. The reason why Spiral 7-X can complete the 30-minute long-term plasma confinement is mainly due to its special external field coil design. , And the most critical water-cooled diverter. "
"Although this water-cooled diverter is also available on the WEGA device, it is something from more than 20 years ago. It is far worse than the one currently serving on the spiral stone. If the STAR imitator intends to replicate the spiral stone 7 -X's success, he had to at least innovate in the cooling device, but it was clear that he did not do it. "
This is not his nonsense, the success of the spiral stone in the thirty-minute long-term restraint is mainly due to the credit of the water-cooled deflector, at least as the Germans declare it.
The newly designed water-cooled diverter will naturally not appear on WEGA devices.
What's more, even if you don't look at these factors, it's almost two months since the scientific review article was published. So far, the STAR Research Institute has not moved at all.
Now Zhou Chengfu can basically be determined that it is not that Lu Zhou does not want to refute him with facts, but that the STAR device cannot do it at all.
Because of this, when he said this sentence, he was not under any pressure.
"... At present, the mainstream of international controllable fusion research is tokamak, and then the inertial constraint of laser ignition, and the anti-field pinch you have just mentioned."
"In theory, every technical route can work. As long as the various problems we face and the problems we are about to face on this route are solved, the final destination is ultimately the fusion we seek. Energy. It ’s like a pickup and a car are all four wheels, and they can get to high speed as long as they pass the toll station. "
Amused by the metaphor of this image, the audience at the scene showed a knowing smile.
After a pause, Zhou Chengfu continued.
"The star simulator is too difficult in engineering. By contrast, Tokamak's design is simpler and the engineering difficulty is relatively low."
"We don't have to try every technology route ~ EbookFREE.me ~ Instead of trying every possibility, it is better to focus limited resources on the few directions that are most likely to be achieved."
"This is a pragmatic choice than a random attempt without a rule!"
...
After the interview, recalling the applause in the previous studio, Zhou Chengfu leaving the studio was relaxed and only felt happy.
Although speaking on such a popular science program did not have a substantial effect, the thought of the young man who did not bother him was a relief in his heart.
Just then, the phone in his pocket suddenly rang.
After looking at the cell phone, I saw that Jia Liang had called it, so he pressed the connection button and stuck the cell phone to his ear.
"Hey?"
"Zhou, Director Zhou!"
"What's the matter?" Zhou Chengfu frowned at the panic voice.
"It's the STAR Institute!"
Zhou Chengfu said impatiently: "You give me a word to finish, what happened to the STAR Institute."
"Just yesterday, they restarted the experiment!"
Hearing this sentence, Zhou Chengchengfu asked in a hurry.
"They restarted the experiment? I haven't heard anything at all? Tell me, what was the result of his experiment? Is it thirty minutes?"
Listening to this general problem, Jia Liangcai had a bitter smile on his face.
"It's not thirty minutes ..."
Hearing it was not thirty minutes, Zhou Chengfu was relieved.
However, he wasn't half relieved, and he was doomed.
Jia Liangcai, on the other side of the phone, continued to speak in an unbelievable tone.
"... The report I saw in Jinling Daily, they seemed to have confined time for an hour ..."
