The moment Fang Xu saw the files in the USB flash drive, a look of surprise flashed across Fang Xu's face.
At the same time, he subconsciously double-clicked the left mouse button to open the file.
The next moment, a detailed drawing appeared on the snow-white wall!
"This is..." Hong Qiming shrank his pupils suddenly, looked at the blueprint in front of him, and muttered to himself.
Not only Hong Qiming, but Fang Xu and all the researchers in the laboratory froze in place, staring blankly at the blueprint in front of them.
As the head of the nuclear physics laboratory, Fang Xu immediately combined the drawing in front of him with the sketch on the blackboard.
He swallowed slightly, and asked in a hoarse voice, "Lu...Yongchang, is this a detailed drawing of the controllable nuclear fusion reactor?"
Lu Yongchang naturally smiled and nodded: "Of course, to be precise, this is the detailed drawing of the reactor."
"Now, do you believe what I say?"
Hong Qiming also recovered from the shock, looking at Lu Yongchang in front of him, his eyes were shining brightly!
"Good boy... You did this by yourself?!"
Although he already had the answer in his heart, he still couldn't believe it.
Complete such a drawing alone...
Although he doesn't know much about scientific research, he also knows how much knowledge is needed to complete such a blueprint!
Under normal circumstances, this kind of drawing requires several people, or even several teams to work together to complete it!
Lu Yongchang smiled and nodded, affirming Hong Qiming's question.
Hong Qiming's eyes trembled slightly, although he couldn't understand the blueprint, nor did he know its authenticity and reliability.
But...he could see from the expressions of Fang Xu and the researchers, how amazing the blueprint in front of him was!
Fang Xu on the side exhaled slightly, and glanced at Lu Yongchang with complicated eyes.
Just now, he felt that it was a wrong decision to entrust such a heavy responsibility to this brat.
But now, he decided to take back his unspoken words.
Where is this boy? !
This is simply, simply not human!
Fang Xu burst out a swear word from the bottom of his heart!
In the entire history of Xia Kingdom, he had never heard of anyone who could single-handedly complete the blueprint of a large-scale equipment!
Although this is only a part of the blueprint of the controllable nuclear fusion reactor, it is amazing enough!
"You... How long did you spend to complete this drawing?"
Fang Xu asked with a trembling voice.
Lu Yongchang glanced at Fang Xu's face quietly, and said with a smile: "Uh...almost a year?"
Fortunately.
For more than a year, it can be considered acceptable... Shit!
Fang Xu's expression was a little distorted: "It took you just over a year for such a complicated thing?!"
Then these researchers, have they spent nearly ten years on dogs? ?
Chapter 14 Stellarators and Tokmaks
Faced with Fang Xu's doubts, Lu Yongchang could only curl his lips slightly.
This is what I said too much!
If Fang Xu knew that this blueprint was drawn by himself all night, he would probably be on the dissecting table by now, right?
"It's just a blueprint of a reactor, and it's far from the entire controllable fusion reactor!"
Hearing Lu Yongchang's Versailles-like words, the corners of Fang Xu's mouth twitched violently.
In his 45 years of life experience, Lu Yongchang should be the most pretending he has ever seen, right?
But soon, he noticed something strange.
"and many more!"
"This reactor..."
Fang Xu's voice made everyone's hearts twitch.
Hong Qiming couldn't help but looked at him.
Could it be...the blueprint of this reactor is wrong? !
"This is not a tokmak device!"
Fang Xu shouted in surprise!
There was a bit of a smile in the corner of Lu Yongchang's eyes.
As expected of Academician Fang, he really couldn't hide it from him!
"Of course this is not a tokmak device!"
"This is a stellarator."
Lu Yongchang chuckled and said, "If my calculations are correct, ITER's controllable fusion time should be within 30 minutes, right?"
Fang Xu's eyes moved slightly, and he nodded slightly: "That's right, according to the latest experiment results, the fusion reaction lasted for about 26 minutes."
"Could it be that……"
"Hehe..." Lu Yongchang smiled faintly: "If there is no accident, ITER will touch the ceiling of the tokmak device soon!"
Fang Xu's pupils shrank suddenly: "You mean... the tokmak device is not the optimal solution to achieve controllable nuclear fusion?!"
Lu Yongchang nodded in affirmation of Fang Xu's statement.
"How is it possible... If this is the case, wouldn't human beings have been on the wrong path for decades?!"
Fang Xu froze in place, muttering to himself.
He couldn't accept Lu Yongchang's statement!
Lu Yongchang naturally understood Fang Xu's complicated mood at this time.
In the previous life, in order to break the monopoly, all the scientific research strength of the Xia Kingdom was invested in the research and development of the tokmak device!
However, no matter how hard you try, the maintenance time of controllable nuclear fusion cannot exceed 10 minutes!
This was a fatal blow to the confidence of all scientific researchers at the time!
If Fang Xu hadn't learned of the flaws of the tokmak device by chance, Xia Guo would probably make a mistake on the road to realizing controllable nuclear fusion!
"I... how can I verify your statement?!"
As expected, Fang Xu is currently the top scientist in the Xia Kingdom. After a brief absence, he immediately came to his senses and asked Lu Yongchang in a deep voice.
Lu Yongchang shrugged and said lightly: "It's very simple, you just need to find a basic stellarator, use the material I deduced to build a reactor, and then ignite nuclear fusion, which can naturally be verified. "
Fang Xu's eyes moved slightly.
He remembered that in the laboratory, there was indeed an "obsolete" stellarator device that was bought at a high price.
"and many more!"
Hong Qiming's resonant voice suddenly sounded from the side.
"You guys... who can explain to me what the stellarator and tokamak device mean?"
While speaking, Hong Qiming cast his eyes on Lu Yongchang.
Seeing this scene, Guan Hualiang and Fang Xu took a step back and handed the stage to Lu Yongchang.
Lu Yongchang pondered for a moment, and then said, "Hong Bu, you should be clear that controllable nuclear fusion requires a strong magnetic field to confine the fusion material, right?"
Seeing Hong Qiming nodded, Lu Yongchang was slightly relieved.
That's easy to explain!
Otherwise...he still needs to explain the principle of controllable nuclear fusion from the beginning!
Although it is something that can be solved with a few words, it is still a bit troublesome after all!
"To put it simply, the tokmak device's toroidal helical magnetic cage requires plasma current, but the stellarator does not. It can directly generate a twisted toroidal magnetic cage through an external coil."
"Then... is there any difference between these two? Don't they both generate magnetic fields?"
A trace of confusion appeared in Hong Qiming's eyes.
"Snapped!"
Lu Yongchang snapped his fingers lightly.
"That's the point I'm going to say!"
"In the tokmak device, the plasma current is as high as tens of millions of amperes. Such a huge current will inevitably bring about countless problems."
"For example, distortion modulus, magnetic surface tearing, magnetic island generation, etc.!"
"All of this would reduce the ability to confine the plasma."
"The consequences will range from flameout to explosion!"
While speaking, Lu Yongchang made an explosive gesture.
Hong Qiming nodded with a half understanding.
Although he didn't understand the various technical terms that Lu Yongchang said, he understood the last sentence.
Will the tokmak device explode? !
Hong Qiming looked at Academician Fang Xu standing next to him with a complicated expression.
Facing Hong Qiming's gaze, Fang Xu had no choice but to nod his head and said: "There is such a possibility, but... so far, the tokmak device has not had such a serious failure!"
"Not now, what about in the future?" Lu Yongchang said lightly, "When the fusion maintenance time is increased to 30 minutes, maybe serious consequences will appear!"
Fang Xu froze suddenly, and exclaimed in surprise: "You mean, the tokmak device will explode after 10 minutes of fusion three?!"
Lu Yongchang nodded with a complicated expression: "Yes, this is also the biggest trap of the tokmak device."
"Although the poloidal magnetic field formed by the plasma current makes the structure of the magnetic cage very simple, high temperature and ultra-high current will eventually lead to some accidents."
Fang Xu suddenly realized: "So it is! So it is!!"
"What about the stellarator?" Hong Qiming swallowed slightly and asked in a low voice.
He suddenly had a feeling that the immature sophomore in front of him was like an old professor who had been immersed in it for decades in this respect!
Even Fang Xu, in front of him, is like a student!
Hearing Hong Qiming's question, Lu Yongchang said lightly: "The stellarator is simple, you only need to create a closed and twisted ring-shaped magnetic cage inside through the external coil!"
Hong Qiming: "???"
"So simple? Then why didn't you use stellarator before?!"
Fang Xu glanced at Lu Yongchang unhappily, and explained again: "The difficulty of the stellarator is the manufacture of the external coil."
"First, the shape of the external coil is irregular, which is a major difficulty in manufacturing."
"On the other hand, to form a strong enough magnetic field, the material of the coil, it is best to use a superconducting coil, which increases the difficulty."
"After all, there is no breakthrough in normal temperature superconducting technology."
Lu Yongchang's faint voice came from the side: "What if I can solve the problem of room temperature superconducting materials?"
Chapter 15 Carbon Nanomaterials Laboratory
"what?!"
As Lu Yongchang's voice fell, Fang Xu's eyes widened slightly, and he exclaimed in surprise: "Can you solve the problem of room temperature superconducting materials?"
Fang Xu's reaction made Hong Qiming frowned.
"Normal temperature superconductivity... I remember, our country should have this technology?"
"Last time I saw a report that a famous academician of the Academy of Sciences broke through the room temperature superconducting technology!"
Fang Xu glanced at Hong Qiming helplessly, and said softly: "Hong Bu, what you are talking about should be the paper that academician Hu Changping published in Nature magazine some time ago!"
