The Daya Bay slow neutron irradiation experiment has been completed. Judging from the relevant test reports, this carbon composite material made of zirconia as an additive and catalyst has excellent performance in neutron irradiation resistance.

Although it is only a slow neutron radiation detection in low-energy areas, the excellent data is enough to support Xu Chuan to turn on the dawn fusion device again to test the neutron radiation resistance of this material in a truly high-energy environment.

The research and development of first wall materials is a very difficult thing in itself.

They are already lucky to find a path to the other shore in the fog.

As for how far the other side is, you will know after the actual test is completed.

The relevant preparations are carried out in an orderly manner under the busyness of many engineers and researchers.

After a New Year, the sleeping fusion pile will start again, but I don’t know if it will bring good news of joy this time or if it will bring them back to the fog of chaos.

Meanwhile, on the other side.

Europe, in the Plasma Planck Institute in northern Germany.

A group of plasma physicists from EU countries are discussing and discussing in a large general control room.

The advanced achievements of the Dawn Fusion Device have made the United States worry about its international status and have further taken more measures and means.

Iter's seven member states have thus become six today.

Professor Xu also responded to this as usual, and the cancellation of the sale of high-temperature copper-carbon-silver composite materials to the IR and related member states is a response.

I have to say that the United States is really a messing stick.

Iter has been shaking in recent years. A little fusion light that finally reignites, but it is immediately shaking by the other party.

Perhaps they think that after clearing China from iter, they can stop and slow down the other party's research progress on controlled nuclear fusion.

But the one who led the Dawn fusion device forward was that Professor Xu, who was good at creating miracles, would have to be that simple.

Now, iter is almost dead in name only. In Europe, after losing the opportunity to obtain high-temperature copper-carbon-silver composite superconducting materials from that person, the Planck Plasma Research Institute is the only seedling.

Although the Planck Plasma Research Institute and Professor Xu traded technology rather than materials, the relevant contracts also stipulate that high-temperature superconducting material technology is limited to the Planck Plasma Research Institute's own use.

Of course, there are many ways for them to get around this contract agreement, but how could the German and Planck Institute of Plasma give up their advantages?

Is it not good to let countries gather funds and funds here?

Anyway, there are reasons, and the question is the contract agreement.

Based on this, other EU countries have no choice. The best choice is to cooperate with the Planck Plasma Institute.

It has to be said that after the entire EU gathered together, with sufficient scientific research funds and the support of a large number of scientific researchers, the progress of Spiral Stone 7 in the field of controlled nuclear fusion is quite fast.

Originally, it had to risk damage to the first wall to run the high-density plasma barely for nearly an hour. After scientific researchers from other countries joined, especially mathematicians in France redesigned a control plan for the high-density plasma turbulence of the spiral stone 7, the running time was close to the two-hour record created by dawn.

After seeing hope, the Planck Plasma Research Institute also followed Xu Chuan's footsteps and began to deepen the fusion of deuterium and tritium raw materials.

Unfortunately, the problem of neutron radiation is always like a roadblock, standing on the road ahead.

Even if we gather experts in the material field, we can never advance that little distance on this road.

Of course, the first wall material itself is a super problem, and it is normal for no progress in a short period of time. However, this is a bit unacceptable for the various financial leaders behind the Spiral Stone 7.

In the control room, his eyes were locked on the device that was gradually stopping through the surveillance screen. The supervisor Robert Mc, who was standing in the main control room, looked at Tilman Rent on the side.

"When can we keep up with China and conduct ignition experiments?"

Hearing this problem, Tilman Rent couldn't help frowning and said with a headache: "It is impossible to guarantee that the radiation problem of the first wall has never made any progress. If this problem cannot be solved, forcibly igniting will cause great damage to the spiral stone 7."

"What about neutron anti-materials? Is there any progress?" Robert Mc continued to ask: "I always need some results to explain to the top."

Upon hearing this, Tilman Lent smiled bitterly and said, "The materials have been tested a lot, whether it is tungsten, molybdenum, or austenite steel used in China, or even ceramics. It cannot break through the previous records."

After a pause, he continued: "And, judging from the progress of the materials laboratory, most metal materials may not be used on the first wall, whether it is tungsten, molybdenum, or zirconium. "

"These metal materials are exposed to high-energy neutron beams of 14.1 mev level, and the off-position effect and swelling effect of metal bonds are too serious."

"If we only resist neutron radiation simply, we have some solutions, but the neutrons produced by deuterium-tritium fusion are the key to maintaining tritium self-sustainment, and we cannot reflect them all back."

"Perhaps, the metal path may not be suitable for the first wall materials. We should consider ceramics, carbon nanomaterials, such as graphene or carbon nanotubes."

Robert Mc frowned and said, "Nanoceramics and carbon nanomaterials are old things, so have you not found anything new?"

Tilman Rent shrugged helplessly and said, "There are indeed many non-metallic materials, but you don't know how harsh the environment the first wall material needs to face."

"High temperatures of thousands of degrees, impacts of various high-energy particles, radiations of various radiations, and the most troublesome high-energy neutron beams, each of which is a big trouble."

Robert Mike sighed, how could he not know these questions as the director of the Planck Plasma Institute?

Just to catch up with or even surpass China, they must take the lead in the first wall material.

After thinking for a while, Robert suddenly asked, "You said, how would that Professor Xu solve this problem?"

Hearing this question, Tilman Rent fell into deep thought. After a while, he smiled bitterly and shook his head, saying, "I don't know, I can't think of it."

"He is a man who is good at creating miracles and a real genius. To be honest, this genius who is rare throughout history may have a completely different perspective than ours."

"Otherwise it would be hard for me to imagine how he did so many great achievements at such a young age."

Looking at the spiral stone 7 behind the screen, Tyrman paused for a moment and then said, "It would be great if China did not leave iter. In this way, we might be able to visit and communicate with China through iter."

"After all, sometimes one way of thinking is enough to push the progress far away."

On the side, Robert didn't say anything, but just sighed slightly.

Stop dreaming.

China has left, and it is impossible to think about this now.

What's more, in a sensitive field such as controllable nuclear fusion, no one can selflessly share the advanced technology in their hands.

The United States is really awesome, it can be demolished wherever it goes.

It's not just that iter is almost overwhelmed, but I heard that life in Cern is not easy either.

Under the semi-forced nature, Cern had already reached cooperation, and even had a contract to transport some high-temperature superconducting materials, which were forced to terminate.

Although Sakura Kingdom and the United States quickly signed a new contract and paid part of the scientific research fund, it is not known how long it will take for the restart of LHC.

After losing the high-temperature superconducting materials and the support of Professor Xu, the detection and discovery of dark matter and dark energy can be said to be indescribable and hopeless.

Many scholars in the fields of high-energy physics and particle physics have extremely pessimistic views on this.

Even Cern might fall into the footsteps of iter.

On the other side, China and Jinling.

Xu Chuan was not very clear about the progress of the Planck Plasma Research Institute. This was not true in the previous life when the EU joined forces.

However, controlled nuclear fusion is not a problem that can be accumulated and solved by manpower.

Human resources can accelerate the research and development and advancement of some conventional technologies, but those top world problems

For example, mathematical model of plasma turbulence, first wall material, or high-temperature superconducting materials with excellent performance are not technologies that can rely on human-powered piles.

At least it is impossible in a short period of time, and there may be a glimmer of hope for long-term investment.

Of course, it's just a glimmer of hope.

For example, the mathematical model of plasma turbulence is based on the perfect solution of n-eq, and the precondition is a millennium mathematical conjecture.

Not to mention the latter material.

Unless you have a lot of luck in top-quality materials, you can only rely on experience to explore a little bit.

Although he is concerned about the progress of Europe in controlling nuclear fusion, in contrast, he is more concerned about the performance of carbon composite materials synthesized by zirconia under high-energy neutron radiation after the Dawn Fusion Device is turned on this time.

After all, it is better to keep your advantage and be ahead than to expect others to be outdated.

Under the leadership of Zhao Hongzhi, the engineer team placed ten groups of zirconia carbon composite materials and ten different control materials on the first wall.

Immediately, the comprehensive inspection was completed, and the steel giant beast lying quietly in the core experimental area made a light sound, which was the sound of a powerful current flowing through the outer field coil.

Supported by the excellent superconducting performance of high-temperature copper-carbon-silver composite superconducting materials, electrical energy is quickly converted into a magnetic field, controlling the high-temperature deuterium-tritium plasma in the reactor chamber to run.

In the main control room, Zhao Guanggui stood nervously behind Xu Chuan, his eyes switching back and forth between the console and Xu Chuan's back.

For him, controlled nuclear fusion engineering is the largest project he has ever participated in, not to mention that he has also taken on the important task of solving problems related to the first wall materials.

I heard that this project has spent more than 50 billion rmb of funds so far, but it feels terrible to think about it.

He even couldn't fully understand what the concept of 50 billion was.

The cost of this dawn fusion device in front of me is as high as 2.5 billion, not to mention that it has been renovated many times one after another, each time with a fund of tens of millions or even hundreds of millions of dollars.

If the zirconia carbon composite material does not have such an ideal effect this time, he doesn't know how to face the experimental results.

p: Yesterday I took my father to the last Xiangya Hospital for follow-up visit. The relevant examinations have been basically completed. I prescribed medicine and got the order. It was already evening. I took him back to my hometown and rushed back to Changsha today. So yesterday's update was posted today (because time was urgent, I didn't bring any computers or anything else).

There are two more chapters today.

In addition, I promised you to build a group after handling this matter. It has been done. There is a link at the end of the chapter. Those who are interested can come in and play.
