Half a month later.
Inside the Nuclear Physics Laboratory of Sandaokou University.
Lu Yongchang sat quietly in an office assigned to him alone.
He frowned slightly and used the pen in his hand to quickly calculate some formulas on the A4 paper in front of him.
Half a month later, the room-temperature superconducting wire made of carbon nanotube material has been completed.
It has to be said that the power of the state apparatus is extremely huge!
The moment he learned about the breakthrough in room-temperature superconducting material technology, Hong Bu personally issued the manufacturing order.
Although Lu Yongchang has a complete plan for preparing carbon nanotubes, but... because of the manufacturing process problems at the time, in the entire Xia country, only the Xia Sheng Group, which specializes in the manufacture of high-precision equipment, can mass-produce superconducting wires that meet the standards.
As for those foreign companies...
Hong Qiming is not a fool. If he really gives them the order, it is estimated that within a few days, several Western powers should be able to "master" the room-temperature superconducting technology!
Stimulated by large amounts of funding and administrative orders, Xia Sheng Group's carbon nanotube wire manufacturing capacity continues to expand!
In just half a month, room-temperature superconducting wires worth hundreds of millions of yuan were transported to the nuclear physics laboratory of Sandaokou University.
At this time, an old-style stellarator device had been installed in the nuclear physics laboratory.
However, at this time, the spiral wires on the outer layer of the stellarator had all been removed by the staff.
As for the inner cavity of the stellarator, it had been replaced with a newly manufactured inner cavity a few days ago.
The material used for the new inner cavity is naturally the new material deduced by Lu Yongchang on the blackboard!
According to material tests, the inner cavity of the reactor made of this new material can perfectly withstand the high temperature of hundreds of millions of degrees when nuclear fusion reactions occur!
In addition, when Fang Xu was conducting material testing, he was surprised to find that this new material can perfectly resist the radiation damage caused by nuclear fusion.
While Fang Xu was surprised, he also felt a sense of admiration for Lu Yongchang in his heart.
Such powerful material was actually deduced on paper by a sophomore undergraduate student!
Fang Xu couldn't help feeling a little ashamed.
At his age, he is really living a dog's life!
Lu Yongchang naturally had no idea what Fang Xu was thinking. At this moment, he was sitting in the office carefully checking the size parameters of the stellarator.
According to Fang Xu, this star simulator was originally used for research in Country D.
As for why it is no longer used...it naturally returns to the original question.
The manufacturing difficulty of a stellarator is extremely huge!
Unlike the Tokamaca's regular spiral shape, the stellarator's appearance is like a tangled ball of wool!
The position of each wire needs to be carefully calculated to ensure that it can generate a magnetic field at a specific angle!
At this time, Lu Yongchang was completing this task.
He needs to calculate the precise position of each superconducting wire based on the size parameters of the stellarator to ensure that a closed, twisted annular magnetic cage can be formed in the inner cavity of the stellarator to confine the extremely high temperature plasma.
…
"call..."
Lu Yongchang gently put down the pen in his hand and let out a long breath.
After several days of calculation, we finally achieved gratifying results.
According to his calculations, these superconducting coils can provide a strong magnetic field with an intensity of up to 100T.
This will be the most powerful artificial magnetic field on Earth!
This 100T strong magnetic field can perfectly confine the fusion plasma of hundreds of millions of degrees in the center of the reactor cavity!
He stood up, walked slowly to the office door, and gently turned the doorknob.
The sound of the office door opening attracted Fang Xu's attention.
"Hmm? Have you completed your calculation task?"
Seeing the relaxed expression on Lu Yongchang's face, Fang Xu's eyes flashed with surprise and he asked immediately.
It's only been a few days?
At most, it would be just a little more than three days, right?
Could Lu Yongchang complete such a complex computing task within three days?
Fang Xu didn't believe it from the bottom of his heart.
As if he saw the doubt in Fang Xu's eyes, Lu Yongchang chuckled and said, "Of course it's done!"
As he spoke, he handed a stack of A4 papers to Fang Xu: "How about... you check it?"
Fang Xu took the A4 paper handed over by Lu Yongchang with a look of surprise.
When Fang Xu saw the densely packed calculation formulas above, he swallowed slightly.
Although he didn't want to admit it, he seemed to have trouble understanding the calculation method above.
"Ahem...I believe your calculations!"
Fang Xu returned the stack of A4 paper to Lu Yongchang with a serious face and said, "How about...let Tianhe-1 verify your calculation results?"
Lu Yongchang was stunned for a moment, then nodded slightly, agreeing to Fang Xu's proposal.
As it concerns controlled nuclear fusion, all research resources are given priority to the Sandaokou Nuclear Physics Laboratory.
As soon as the application was submitted, the usage time of Tianhe-1 was allocated.
Fang Xu carefully input each result calculated by Lu Yongchang into the computer, and then Tianhe-1 performed the calculations.
At this time, the role of the supercomputer was fully demonstrated.
In just half an hour, the calculation results appeared in front of Fang Xu and Lu Yongchang.
Success!
…
The release of the superconducting wire layout plan means that the transformation plan of the stellarator has reached the final step.
Coil holders at specific angles are installed outside the stellarator.
These brackets can hold the coil in place.
After all, for a stellarator, even the slightest shift in the position of the external superconducting coil would mean a disaster.
Once the internal annular magnetic cage is destroyed, the plasma at hundreds of millions of degrees will directly touch the inner cavity surface!
I believe no one would want to see such consequences!
Therefore, when completing the final transformation of the stellarator, both Lu Yongchang and Fang Xu were extremely alert, fearing any minor mistakes.
…
Three days later.
The transformation of the old stellarator has been completely completed.
"Yongchang, when do we start the first ignition experiment?"
Fang Xu's voice sounded from the side.
Unconsciously, Fang Xu had already regarded Lu Yongchang as his superior. Before making every decision, he would first ask Lu Yongchang for his opinion.
"Right now!"
Lu Yongchang's eyes flashed, and he moved his eyes away from the A4 paper on the desk and said in a deep voice: "Academician Fang, report it."
"This afternoon, we will start our first ignition experiment!"
As Fang Xu submitted an application to Hong Qiming for the first ignition experiment, some changes also occurred in Sandaokou University.
Dozens of special forces soldiers entered Sandaokou University in plain clothes, and all main roads leading to the nuclear physics laboratory were blocked.
Even on some high-rise buildings near the nuclear physics laboratory, snipers had already set up sniper rifles and observation equipment in advance.
It is no exaggeration to say that at this time in the nuclear physics laboratory, even a bird could not fly safely through!
All of this is to ensure that the controlled nuclear fusion experiment is not interfered with by any external unknown factors!
