After hearing Xu Yuan's answer, Li Guojian nodded frequently. His originally worried heart finally calmed down. As long as the supply of room-temperature superconducting materials can be guaranteed, a new tokamak device can be built quickly after dismantling the original device.

Then the two left together and continued to discuss the next work content on the way.

Perhaps everyone wants to see the Tokamak nuclear fusion device, which is made entirely of room-temperature superconducting materials, built and ignited as soon as possible.

After everyone learned about the existence of room-temperature superconducting materials, they began to take concrete actions in the afternoon as soon as the decision-making meeting ended in the morning.

The efficiency is quite fast.

Mainly because it is not an easy task to even dismantle such a large tokamak device.

The entire process needs to be professional.

Normally, even at the fastest speed, it would take at least several months to complete.

Moreover, during this period of time, nuclear fusion experiments cannot be carried out normally.

If this happened in any other nuclear fusion laboratory, it would be impossible for this to happen.

It will not be passed.

After all, not everyone can have room-temperature superconducting materials.

It can only be said that the artificial sun project of Science Island entered a new level the moment Xu Yuan joined, which is totally incomparable to other laboratories.

that's it.

In the following period of time, the work of the artificial sun project members at the Institute of Plasma Physics on Science Island changed from previous experiments to dismantling the device.

And Li Guojian was personally in charge of the command.

Fortunately, what happened inside was kept confidential. If outsiders saw it, they would probably think that the Chinese were planning to give up the research on controlled nuclear fusion devices.

The main problem is that not only will the project not progress, but it will also be overtaken by other countries that are catching up.

Lost the original leading advantage.

However, all the project members became more and more motivated as they worked harder.

There was no drop in energy levels.

As for Xu Yuan, he was naturally not idle. In addition to controlling the synthesis of room-temperature superconducting materials, he also often stayed in the office to design new tokamak device design drawings.

First of all, the supply of room-temperature superconducting materials is definitely the key issue.

As the emperor of the materials world, although its production cost is only slightly higher than that of new aerospace materials, its synthesis cycle is relatively long, which leads to very limited production capacity.

In addition, the construction of a specialized material production base has not yet begun, so even less material can be produced at present.

However, without enough room-temperature superconducting materials, the new tokamak nuclear fusion device cannot be built.

If the original equipment in the courtyard is dismantled, it will lose its meaning.

It will further delay the research progress of nuclear fusion.

This is obviously what Xu Yuan does not want to see.

What's more, he had already promised Li Guojian that he would definitely do a good job on this matter and ensure the supply of room-temperature superconducting materials.

I will definitely not let what I say go to waste.

So, after the Academy of Sciences and higher authorities gave the green light, material laboratories at major domestic universities all got involved and jointly synthesized room-temperature superconducting materials to meet the needs of Science Island.

Even if a laboratory wants to keep samples for research, it is not allowed for the time being.

With this method, the urgent problem was temporarily solved.

According to estimates, it will have little impact on progress.

As for the design work of the Tokamak nuclear fusion device, since the new device has changed the materials, the original design drawings are definitely no longer applicable.

The most intuitive problem is the size of the device.

The low-temperature superconducting materials used in the past require a large number of bulky equipment to be arranged on the temperature control system to ensure that the reaction temperature is at the critical temperature. Therefore, the appearance, floor space and volume of the Tokamak device reported on the Internet look very large and shocking.

Now the material has undergone an upgrade and can exhibit excellent superconducting properties at room temperature.

All the original ancillary equipment can be discarded.

You can focus all your attention on the tokamak device itself.

Consider how to maintain temperature for a long time.

With the help of the panel progress bar, Xu Yuan can find the direction in which the progress bar grows the most.

If we design it in this direction, I believe that the tokamak nuclear fusion device that will eventually be built will not disappoint everyone.

Surprises are a must.

As time passed, it was already the end of October.

After several months of hard work, the dismantling of the tokamak device is progressing very smoothly.

It's basically coming to an end.

This made everyone in the hospital feel very happy, as if a huge stone had been lifted off their shoulders.

There are basically no problems with the materials.

With the joint efforts of laboratories of major domestic universities, the production capacity has almost reached expectations.

However, because there has been no news about the Plasma Research Institute and Xu Yuan on the Internet during this period, netizens are somewhat worried, fearing that even if Xu Yuan is there, the progress of the artificial sun cannot be improved.

After previous overseas national nuclear fusion laboratories, they expressed pessimism about the tokamak device in the articles they published.

This incident also spread to the country.

Because everyone firmly believed that the tokamak device would work, but several months passed and not even a splash was made.

It's inevitable to feel a little lost emotionally.

In addition, many overseas media seized the opportunity and began to export their own views to the country.

To sum up, they are touting their laser nuclear fusion and criticizing the tokamak device.

The subsequent discussion about this matter even became a hot topic, attracting heated discussions among many netizens, who expressed their opinions on the situation.

"It's been almost half a year, and there's no progress at all. Logically speaking, with Dean Xu's participation, the project should be progressing very quickly."

“It doesn’t feel good.”

"After all, this is controlled nuclear fusion research, the ultimate challenge facing human civilization. Even Dean Xu shouldn't be able to solve it so quickly. It's normal that there's no news now."

"The main tokamak device does have limitations, and it will be difficult to develop further without breakthroughs in materials."

"I feel that overseas laser nuclear fusion is a feasible method. After all, it imitates the temperature and pressure of the sun. Maybe we can switch directly to the research of laser nuclear fusion now."

"So many past examples have told me that if I trust Dean Xu, everything will be fine."

"That's right. Anyway, I believe in President Xu. We will definitely be the first country in the world to master nuclear fusion."

"Not to mention that it's only been less than half a year. It's normal for nuclear fusion to have no news for five years. Let's just wait and see."

……

It is no exaggeration to say that at this time, Xu Yuan put all his energy into popularizing nuclear fusion devices.

I don’t pay any attention to what is being said online.

After a period of hard work, he finally completed the design schematic of the room-temperature superconducting material tokamak device. In addition, the original device had been successfully dismantled, so he could officially start construction and prepare for the subsequent ignition test.

10 month 28 day.

on Monday.

That morning, a discussion meeting on the Tokamak device was held again in the lecture hall.

As the meeting proceeded according to the process, a researcher in his thirties soon stood up and summarized and reported on his work in recent months.

……

"We have now successfully dismantled the tokamak device and eliminated all safety hazards."

"We can start the next step of construction planning at any time."

After listening to the report, Xu Yuan and Li Guojian also had a bright smile on their faces.

Because this means that they are finally going to start building a brand new tokamak device.

When I think about the device built with room-temperature superconducting materials, and what kind of data alcohol will show after the ignition reaction test, I can't help but feel excited.

After listening to this report, Xu Yuan also let out a sigh of relief.

I thought I had finally completed all the preparations.

Because he successfully conquered room-temperature superconducting materials, he was sent to Science Island by the institute to conduct research on controlled nuclear fusion. He definitely wanted to complete this ultimate problem of human civilization in the shortest time possible.

Now that all preparations are ready, the construction of the new Tokamak nuclear fusion device can be slightly accelerated.

The discussion meeting will continue as normal.

Some professors and researchers also proposed their own optimization solutions.

But they are basically improvements based on the original ones, and may not be suitable for the tokamak device made of room-temperature superconducting materials.

As a result, the final construction plan has not been finalized.

The reason why Xu Yuan did not come up with his own plan right away was that he wanted to give others more opportunities, which would also help improve their level.

When he saw that the argument had reached a bottleneck, he decided not to keep it a secret any longer.

He first coughed twice to attract everyone's attention, and then took over the conversation directly.

"In fact, in the past few months, in addition to being responsible for the synthesis of room-temperature superconducting materials, I also found time to complete the design drawings of the new tokamak nuclear fusion device."

"Now we can discuss it together and finalize the final design plan as soon as possible."

"This way we can start construction sooner."

Almost as soon as Xu Yuan finished speaking, a design drawing suddenly appeared on the screen in the lecture hall. A closer look revealed that it was the tokamak device.

At this moment, no one in the lecture hall, including Li Guojian, had obviously expected that Xu Yuan had even prepared the design drawings.

Although the main students are talented in many fields, this time they came here under the name of conquering room-temperature superconducting materials, which made everyone involuntarily assign Xu Yuan to the materials focus.

As for the design drawings of the new tokamak nuclear fusion device, they still need to complete them.

The actual situation turned out to be completely different from what was imagined. Xu Yuan actually completed the design drawings of the Tokamak device while ensuring the supply of room-temperature superconducting materials. After hearing what Xu Yuan said, everyone was stunned for two seconds before they came to their senses and carefully examined the drawings.

At a glance, the drawing still shows a circular container, but both in terms of volume and size, it is obviously much smaller than the original device.

However, everyone is a professional in charge of this project and is aware of the rationality of the design of the tokamak device.

Basically, it doesn't take too long to judge whether it is good or bad.

Then decide whether to adopt it.

Xu Yuan remained silent for the time being, giving others time to digest his design drawings.

So as time passed, everyone first studied it seriously, and then began to communicate and discuss in a low voice with others around them.

Later on, the expression on his face became more and more excited.

It is obvious that they are very recognized.

Among them, Li Guojian's reaction was the greatest. While others were still studying, Li Guojian had already turned his body around.

He suppressed his excitement and said to Xu Yuan:
"Xu Yuan."

"Do you know what I'm thinking right now?"

"Anyway, I regret it very much."

"If I had known that you had done such in-depth research on the tokamak device, I should have applied to the institute earlier to transfer you to participate in our artificial sun project."

"In this case, maybe we are already close to achieving controlled nuclear fusion."

Although the last sentence was said with a joking tone, it showed genuine admiration for Xu Yuan.

It seemed that he had been impressed by Xu Yuan's strength.

Xu Yuan listened to everything Li Guojian said, and felt a little embarrassed by such praise.

"Dean Li thinks too highly of me. I'm not that capable yet."

"Besides, even if I had participated earlier, it would have been impossible to achieve controlled nuclear fusion without conquering room-temperature superconducting materials."

"That's indeed true." Li Guojian nodded in agreement.

Then Xu Yuan took the initiative to ask the other party in detail about his design drawings.

"I wonder if Dean Li thinks my design is feasible. If you have any doubts, we can discuss them with each other."

"I think there is no need to discuss this in the next meeting. This plan is definitely the best choice." Facing this question, Li Guojian took a deep breath and said seriously: "If it is the previous low-temperature superconducting material, then the size of this device alone will not be adopted. But after using room-temperature superconducting materials, the adaptability of this design is too high."

"I propose that we finalize the plan as soon as possible and then officially start the construction of the room-temperature superconducting material tokamak device."

As Li Guojian finished speaking, this response was also recognized by other researchers at the scene.

Then they couldn't help but agree.

"Many aspects of the design of this proposal are very clever, and I think it can effectively ensure the stability of strong magnetic field confinement."

"With the characteristics of room-temperature superconducting materials and this solution, the usability of the device can be greatly improved, and more usage environments can be unlocked in the future."

“It seems that the problems we found in the ignition test before can be effectively improved or even avoided through some structural designs in this plan.”

"Director Xu and Director Li, I think this plan does not need to be modified and can be put into use and constructed immediately."

Li Guojian, sitting on the main seat, listened to everyone's responses, and the smile on his face became even bigger.

After all, it is a very happy thing that another problem in the development of controlled nuclear fusion was solved so easily.

And if we proceed as it is now, to some extent, it will save them a lot of time.

We can start building a new tokamak nuclear fusion device at the fastest speed.

The thought stayed here, and Li Guojian took the initiative to suggest:
"It seems that everyone agrees with this plan. In this case, I propose that we start the construction of the device as soon as possible."

"I also really want to see what this new tokamak nuclear fusion device looks like when it is ignited."

When Xu Yuan came up with this design plan, he originally had the idea of ​​starting the construction of the tokamak device as soon as possible.

Now that everyone has reached a consensus, he naturally won't say anything more.

With a faint smile on his face, he immediately made the final decision.

"Well."

"If everyone has no objection to this plan, the project will officially start from tomorrow."

"I'll leave it to you guys from now on."

-

Finally, with everyone excited, the morning discussion meeting was officially declared over.

Starting tomorrow, Xu Yuan and Li Guojian will serve as chief designers to carry out the construction of the room-temperature superconducting material tokamak device.

Because the use of room-temperature superconducting materials makes the Tokamak device smaller than before, the construction period will definitely be shorter.

After detailed calculations and predictions, the Plasma Research Institute finally gave a construction period.

The plan is to successfully build this tokamak nuclear fusion device within a year.

And carry out ignition test.

All project members are undoubtedly looking forward to this day the most.

After all, judging from the current situation, the stable response time of the ignition test of this tokamak device will definitely far exceed the previous record of more than ten minutes.

It may even be possible to achieve stable operation directly.

If this is true, it can definitely be called the most shocking miracle since human civilization began studying nuclear fusion.

Because no one would have thought that someone's research on controlled nuclear fusion would be so successful.

Time flies. In order to ensure that the construction of the tokamak device can be completed within the originally planned time, the holiday time left for project members during this year's Spring Festival is very short.

It can be said that working overtime has become the norm.

For this reason, Xu Yuan and Chen Yuran's family deliberately spent the New Year in Luyang and did not choose to return to Yanjing.

After the new year, the construction of the tokamak device continued in full swing.

It is precisely because of this that the progress is very rapid.

If nothing goes wrong, I believe we will be able to conduct the first ignition test by the end of the year.

Before this, the entire process was kept secret, and even the previous news reports were no longer available.

In contrast, from time to time, national nuclear fusion laboratories overseas have reported news of laser nuclear fusion ignition, and have even announced partnerships with other international nuclear laboratories.

The two sides will share their technical experience and work to accelerate the research on laser nuclear fusion.

It seems that in their understanding, their own laser nuclear fusion is the most advanced nuclear fusion reaction device in the world.
