It's reasonable for me to have a two-way foil for a second-level civilization, right?

It can be said that as long as there is a slight error, the production of this room temperature superconducting material will fail!

While thinking wildly in his mind, he flipped the switch of the test instrument.

Start powering up!

A number appeared on the screen of the test instrument.

Resistance value: 0 Ω!

It worked!

A hint of excitement flashed in Lu Yongchang's eyes.

"Increase some more current!"

Fang Xu's excited voice came from the side.

Lu Yongchang immediately turned the knob and slowly increased the current.

After seeing the resistance value on the screen of the instrument without any fluctuations, all the researchers in the laboratory let out a soft exclamation.

Unlike the researchers around him, Lu Yongchang still had a serious expression on his face.

The test is not over yet.

He also needs to test how the material performs in low pressure environments!

Lu Yongchang winked at Fang Xu who was on the side.

Fang Xu nodded lightly, and turned on the vacuum equipment beside him.

With a low humming sound, the air inside the glass cover was gradually drawn out.

Seeing the value on the barometer decrease slowly, even Lu Yongchang broke into a cold sweat.

You must know that the response of superconducting materials to environmental changes is extremely violent!

For superconducting materials in the past, once the temperature or pressure changes a little, it will directly lead to the disappearance of the superconducting effect!

Under the action of such a strong current, once the superconducting effect of the wire disappears, even if the resistance value is small, extremely powerful heat will be generated instantly.

The consequence...of course, is to fuse the only room-temperature superconducting wire in the world!

Dozens of seconds later.

Looking at the calm resistance curve on the screen of the testing instrument, Lu Yongchang finally showed a bright smile on his face.

He gently wiped the sweat from his forehead, raised his right hand high, and shouted: "Success!"

"We made it!"

Fang Xu on the side turned off various instruments excitedly, rushed to Lu Yongchang's side excitedly, and patted him on the shoulder vigorously: "Good job!"

"The normal-temperature superconducting technology is available, Academician Fang, it's time for us to prepare for the transformation of the stellarator!" Lu Yongchang quickly withdrew from the joy of success and said in a deep voice.

Fang Xu nodded excitedly.

"I'm going to inform the staff in the laboratory that the transformation of the stellarator will start this afternoon!"

Chapter 18 Transforming Stellarator

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 quickly calculated some calculations on the A4 paper in front of him with the pen in his hand.

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 Hongbu learned of the technological breakthrough in room-temperature superconducting materials, Hongbu personally issued the manufacturing order.

Although Lu Yongchang has a complete plan for the preparation of carbon nanotubes, but... because of the manufacturing process problems at this time, the entire Xia Kingdom, only Xiasheng Group, which is responsible for the manufacture of high-end equipment, can mass-produce superconducting materials that meet the standards. wire.

As for those foreign companies...

Hong Qiming is not an idiot, if he really wants to give them the order, it will probably take a few days, and several major Western countries should be able to "master" the room temperature superconducting technology!

Stimulated by a large amount of funds and administrative orders, Xiasheng Group's carbon nanotube wire manufacturing capacity continues to expand!

In just half a month, room-temperature superconducting wires worth hundreds of millions were shipped to the Nuclear Physics Laboratory of Sandaokou University.

At this time, an old-style stellarator device has been installed in the nuclear physics laboratory.

However, at this time, all the spiral wires on the outer layer of the stellarator have been removed by the staff.

As for the inner cavity of the stellarator, it was replaced with a newly manufactured inner cavity a few days ago.

The material used for the new inner cavity is naturally the new material that Lu Yongchang deduced on the blackboard!

According to material tests, the reactor chamber made of this new type of material can perfectly resist the high temperature of hundreds of millions of degrees when the nuclear fusion reaction occurs!

In addition, when Fang Xu was conducting material tests, he was surprised to find that this new type of material can perfectly resist the radiation damage caused by nuclear fusion.

While Fang Xu was pleasantly surprised, a hint of admiration for Lu Yongchang suddenly rose from the bottom of his heart.

Such a powerful material was deduced on paper by a sophomore undergraduate!

Fang Xu couldn't help feeling a little ashamed.

At his age, he really lived like a dog!

Lu Yongchang naturally didn't know the thoughts in Fang Xu's mind. At this time, he was sitting in the office and carefully checking the size parameters of this stellarator.

According to Fang Xu's words, this stellarator was originally used by the research institute in country D.

As for why it's not used... Naturally, it returns to the original question.

The manufacture of stellarator is extremely difficult!

Different from the regular spiral shape of Tokamacana, the shape of the stellarator is simply like a mess of woolen balls!

The position of each strand of 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 strand of superconducting wire based on the size parameters of the stellarator to ensure that a closed, twisted ring-shaped magnetic cage can be formed in the inner cavity of the stellarator to confine the extremely high-temperature plasma body.

……

"call……"

Lu Yongchang gently put down the pen in his hand, and exhaled a long breath.

After a few days of calculation, finally achieved gratifying results.

According to his calculations, these superconducting coils can provide a strong magnetic field with a strength of up to 100T.

This will be the most powerful man-made 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 door of the office, and gently twisted the doorknob.

The sound of the office door opening caught Fang Xu's attention.

"Huh? Have you completed the calculation task?"

Seeing the relaxed expression on Lu Yongchang's face, Fang Xu's eyes flashed with surprise, and he asked immediately.

How many days is it?

It's only a little over three days, right?

Can Lu Yongchang complete such a complex calculation task in three days?

Fang Xu couldn't believe it in his heart.

As if seeing the doubt in Fang Xu's eyes, Lu Yongchang chuckled and said, "Of course it's done!"

While talking, he handed Fang Xu a stack of A4 papers in his hand: "How about...you check it?"

Fang Xu took the A4 paper handed over by Lu Yongchang with a look of surprise.

Fang Xu swallowed slightly when he saw the dense calculation formulas above.

Although he didn't want to admit it, he seemed to be a bit confused about the above calculation method.

"Ahem... I believe in your calculation results!"

As he said that, Fang Xu returned the stack of A4 papers to Lu Yongchang with a serious face: "How about...let Tianhe-[-] check your calculation results?"

Lu Yongchang was stunned for a moment, then nodded slightly, agreeing to Fang Xu's proposal.

Regarding controllable nuclear fusion, all research resources are given priority to the Sandaokou Nuclear Physics Laboratory.

As soon as the application was submitted, the use time of Tianhe-[-] was allocated.

Fang Xu carefully entered each result calculated by Lu Yongchang into the computer, and then Tianhe-[-] performed the calculation.

At this time, the role of supercomputers is fully revealed.

In just half an hour, the calculation results appeared in front of Fang Xu and Lu Yongchang.

It worked!

……

The release of the superconducting wire layout plan means that the transformation plan of the stellarator has reached the final step.

Coil brackets with specific angles are installed outside the stellarator.

These brackets can play the role of fixing the coil.

After all, for the stellarator, once the position of the external superconducting coil shifts a little, it means a disaster.

Once the inner annular magnetic cage is destroyed, the plasma of hundreds of millions of degrees will directly touch the surface of the inner cavity!

I believe no one would want to see such consequences!

Therefore, when completing the final transformation of the stellarator, both Lv Yongchang and Fang Xu were very energetic, for fear of any minor mistakes.

……

three days later.

The transformation of the old stellarator has been completely completed.

"Yongchang, when will we start the first ignition experiment?"

Fang Xu's voice sounded from the side.

Before he knew it, Fang Xu had already regarded Lu Yongchang as his superior. Before making every research decision, he would first ask Lu Yongchang for his opinion.

"Now you can!"

Lu Yongchang's eyes flashed, he looked away from the calculation A4 paper on the desk, and said in a deep voice: "Academician Fang, please report."

"This afternoon, we will start the first ignition experiment!"

As Fang Xu submitted an application to Hong Qiming for the first ignition experiment, some changes occurred in Sandaokou University.

Dozens of soldiers from special forces entered Sandaokou University in casual clothes, and all the main roads leading to the nuclear physics laboratory were blocked.

Even, on some tall buildings near the nuclear physics laboratory, snipers have already set up sniper rifles and observation equipment in advance.

It is no exaggeration to say that even a bird cannot safely fly over the nuclear physics laboratory at this time!

All of this is to ensure that the controlled nuclear fusion experiment will not be disturbed by any external unknown factors!

Chapter 19 Ignition

Naturally, the changes in Sandaokou University cannot be hidden from some caring people.

"What's the situation... Well, why are these roads closed?"

Several boys walked in Sandaokou University, their faces full of depression.

"Could it be that... a big shot has come to the school?"

A boy looked at the blocked road and made a guess.

The other boy shook his head slowly, and said in a deep voice, "It should not be a big shot. I looked at the forum just now, and it seems that all the roads leading to the nuclear physics laboratory have been blocked!"

"what?"
