Cataclysmic Era: I can unlock the tech tree

half a month later.

Inside the nuclear physics laboratory at Sandaokou University.

Lü Yongchang sat quietly in the office that had been assigned to him.

He frowned slightly, his pen rapidly calculating some equations 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 must be said that the power of the state apparatus is extremely immense!

Upon learning of the breakthrough in room-temperature superconducting material technology, Minister Hong personally issued the manufacturing order.

Although Lü Yongchang had a complete carbon nanotube preparation plan, due to the manufacturing process issues at the time, only Xia Sheng Group, which was responsible for manufacturing high-precision equipment, was able to mass-produce superconducting wires that met the standards.

As for those foreign companies...

Hong Qiming isn't stupid. If he really gave them the orders, it probably wouldn't take more than a few days for several major Western countries to "master" room-temperature superconducting technology!

Stimulated by substantial funding and administrative orders, Xiasheng Group's carbon nanotube wire manufacturing capacity has been continuously expanding!

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At this time, an outdated stellarator device had been installed in the nuclear physics laboratory.

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

As for the stellarator's inner cavity, it had been replaced with a newly manufactured one several days ago.

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

According to material testing, the reactor cavity made of this new material can perfectly withstand the high temperature of hundreds of millions of degrees during nuclear fusion reaction!

Furthermore, Fang Xu was surprised to discover during material testing that this new material could also perfectly resist radiation damage caused by nuclear fusion.

While Fang Xu was pleasantly surprised, a sense of admiration for Lü Yongchang also welled up in his heart.

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

Fang Xu couldn't help but feel a little ashamed.

At his age, he's really wasted his life!

Lu Yongchang was naturally unaware of Fang Xu's thoughts. At this moment, he was sitting in his office carefully examining the dimensions of the stellarator.

According to Fang Xu, this stellarator was originally used for research in Country D.

As for why it's no longer used... that naturally brings us back to the original question.

The manufacturing of stellarators is extremely difficult!

Unlike the regular spiral shape of the Tokamacana, the stellarator's shape is more like a messy ball of yarn!

The position of each conductor needs to be meticulously calculated to ensure that it can generate a magnetic field at a specific angle!

At this moment, Lü Yongchang was completing this task.

He needs to calculate the precise position of each superconducting wire based on the stellarator's size parameters to ensure that a closed, twisted annular magnetic cage can be formed inside the stellarator to confine the extremely high-temperature plasma.

……

"call……"

Lu Yongchang gently put down his pen and exhaled a long breath.

After several days of calculations, we 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 at hundreds of millions of degrees to 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 caught Fang Xu's attention.

"Hmm? You finished the calculation task?"

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

It's only been a few days?

All told, it should only be a little over three days, right?

How could Lü Yongchang complete such a complex calculation task in three days?

Fang Xu didn't believe it at all.

Seemingly noticing the doubt in Fang Xu's eyes, Lü Yongchang chuckled and said, "Of course it's done!"

As he spoke, he handed Fang Xu a stack of A4 papers: "Why don't you... take a look?"

Fang Xu took the A4 paper handed to him by Lü Yongchang with a surprised look.

Upon seeing the densely packed calculation formulas above, Fang Xu swallowed hard.

Although he was reluctant to admit it, he seemed to have some difficulty understanding the calculation method above.

"Ahem... I believe your calculations!"

With a serious expression, Fang Xu handed the stack of A4 papers back to Lü Yongchang: "How about... we have Tianhe-1 verify your calculations?"

Lu Yongchang paused for a moment, then nodded slightly, agreeing to Fang Xu's suggestion.

Since it concerns controlled nuclear fusion, all research resources are prioritized for the Sandaokou Nuclear Physics Laboratory.

The application had barely been submitted when the usage time for Tianhe-1 was allocated.

Fang Xu carefully input each result calculated by Lü Yongchang into the computer, which then performed the calculations on Tianhe-1.

At this point, the role of supercomputers became fully apparent.

In just half an hour, the calculation results appeared before Fang Xu and Lü Yongchang's eyes.

It worked!

……

The release of the superconducting wire arrangement scheme signifies that the stellarator modification plan has reached its final stage.

Coil holders at specific angles are mounted on the outside of the stellarator.

These brackets can be used to fix the coil in place.

After all, for a stellarator, even the slightest displacement of the external superconducting coils would mean a disaster.

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

I believe no one wants to see such consequences!

Therefore, when completing the final modification of the stellarator, both Lü Yongchang and Fang Xu were extremely careful, fearing that any minor oversight might occur.

……

three days later.

The renovation of the old stellarator has been completely completed.

"Yongchang, when do we start our first ignition experiment?"

Fang Xu's voice rang out from the side.

Before he knew it, Fang Xu had come to regard Lü Yongchang as his superior, and before making any research decision, he would first ask Lü Yongchang for his opinion.

"Right now!"

A glint flashed in Lü Yongchang's eyes as he looked away from the A4 sheets of paper on his desk and said in a deep voice, "Academician Fang, report this to the higher-ups."

"This afternoon, we will begin our first ignition experiment!"

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

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

In fact, snipers had already set up their rifles and observation equipment on some high-rise buildings near the nuclear physics laboratory.

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

All of this is to ensure that controlled nuclear fusion experiments are not interfered with by any unknown external factors!
