The Daya Bay slow neutron irradiation experiment has been completed, and from the relevant test reports, the carbon composite made by using zirconia as an additive and catalyst has excellent performance in resisting neutron irradiation.

Although it is only a slow neutron irradiation detection in the low-energy region, the excellent data is enough to support Xu Chuan to turn on the dawn fusion device again for a deuterium-tritium ignition to test the material's ability to resist neutron irradiation in a truly high-energy environment.

The research and development of the first wall material is a rather difficult thing in itself.

They were lucky to find a way to the other side in the mist.

As for how far the other side is still there, we will know after the real test is completed.

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

After a new year, the sleeping Daybreak Fusion Reactor will be activated again, but it is not known whether this time it will bring joyful good news or knock them back into the fog of chaos.

At the same time, the other side.

Europe, in the northern Germanic state of the Plasma Planck Institute.

A group of plasma physicists from all over the European Union are discussing in a large general control room.

The advanced results achieved by the Daybreak fusion device have made the United States worry about its international status, and further adopted more measures and means.

This makes the seven member states of ITER six today.

And that Professor Xu also responded to this as always, and the cancellation of the sale of high-temperature copper-carbon-silver composites to ITER and relevant member states was a response.

I have to say that Mi Guo is really a-stirring stick.

ITER has been crumbling in recent years, and it has finally rekindled a little fusion light, but it has been crumbling by the other party immediately afterward.

Perhaps they will think that by removing Hua Guo from ITER, they will be able to stop and slow down the progress of the other party's research on controlled nuclear fusion.

But the one who led the dawn fusion device forward, but Professor Xu, who was good at creating miracles, really had to be that simple.

Today, ITER is dying in name, and on the European side, after losing the opportunity to obtain high-temperature copper-carbon-silver composite superconducting materials from that person, the Planck Plasma Institute is the only seedling.

Although the Planck Institute for Plasma Research and Professor Xu were originally trading for technology rather than materials, the relevant contract also stipulated that the technology of high-temperature superconducting materials was limited to the Planck Institute for its own use.

Of course, there are many ways for them to get around this kind of contractual agreement, but how could the Germanic and Planck Institute for Plasma Research give up their advantage?

Wouldn't it be good for countries to gather money and funds and study them on their side?

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

Based on this, the rest of the EU has little to do, and the best option is to cooperate with the Planck Plasma Institute.

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

Originally, it had to risk damage to the first wall to barely manage the high-density plasma to run for nearly an hour, but after researchers from other countries joined in, especially mathematicians in France, who redesigned a control scheme for the high-density plasma turbulence of the Spiral Stone 7X, the running time was close to the two-hour record set by Daybreak.

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

Unfortunately, the neutron irradiation challenge remains a roadblock.

Even if we gather experts in the field of materials, we have never been able to advance that little distance on this road.

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

In the control room, the eyes locked on the equipment that was gradually ceasing through the surveillance screen, and Robert Mac, the director standing in the main control room, looked at Tillman Lent on the side.

"When will we be able to keep up with Huaguo and conduct ignition experiments?"

Hearing this question, Tillman Lent couldn't help frowning, and said with a headache: "There is no guarantee, there has been no progress in the irradiation problem of the first wall, and if this problem cannot be solved, forced ignition will cause great damage to the spiral stone 7X." ”

"What about anti-neutron materials? Any progress? Robert Mack continued, "I always need something to account for to the above." ”

Hearing this, Tillman Lent smiled bitterly and said, "There have been many experiments on the materials, whether it is tungsten, molybdenum, or austenitic steel used in China, or even ceramics, etc. None of them were able to break the previous record. ”

After a pause, he continued: "Moreover, judging from the progress of the materials laboratory, most of the metal materials may not be able to be applied to the first wall, whether it is tungsten, molybdenum, or zirconium and other alloys. ”

"The off-site effect and swelling effect of these metal bonds are too serious under the irradiation of a high-energy neutron beam of the 14.1Mev class."

"If it's just a simple resistance to neutron irradiation, we still have some solutions, but the neutrons produced by deuterium-tritium fusion are the key to maintaining tritium's self-sustaining, and we can't reflect them all back."

"Perhaps, the road of metal may not be suitable for the first wall material, we should consider ceramics, carbon nanomaterials, such as graphene or carbon nanotubes or something."

Robert Mack frowned and said, "Nano ceramics and carbon nanomaterials are all old things, don't you have any new discoveries?" ”

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

"Thousands of degrees of heat, the impact of various high-energy particles, the irradiation of various radiations, and the most troublesome high-energy neutron beam, each of which is a big trouble."

Robert Mack sighed, how could he, as the director of the Planck Plasma Institute, not know about these problems.

It's just that if they want to catch up with or even surpass the footsteps of Huaguo, they must take the lead in the first wall material.

After thinking for a while, Robert suddenly asked, "You say, how will that Professor Xu solve this problem?" ”

Hearing this, Tillman Lent fell into deep thought, and after half a sound, he shook his head with a wry smile and said, "I don't know, I can't think of it." ”

"He's a man who works miracles, and he's a real genius. Honestly, this kind of genius, which has been rare throughout history, may have a completely different perspective than we do. ”

"Otherwise, it's hard for me to imagine how he managed to do so much at such a young age."

Looking at the Spiral Stone 7X behind the screen, which was conducting experiments, Tillman paused for a moment, and then said, "It would be nice if Huaguo hadn't left ITER." In this way, we may be able to visit China through ITER. ”

"After all, sometimes one idea is enough to push the progress far."

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

Stop dreaming.

Hua Guodu has already left, and it is impossible to think about it now.

What's more, in such a sensitive field as controlled nuclear fusion, it is impossible for anyone to selflessly share the advanced technology in their hands.

The country of rice is really **, where to dismantle it.

It's not just that ITER is about to be tossed and finished, but I heard that life on CERN's side is not very easy.

Under the semi-forced nature, CERN had already reached a cooperation, and even the contract to ship some high-temperature superconducting materials was forced to terminate.

Although Sakura and Mi quickly signed a new contract and paid part of the scientific research funds, it is not known how long it will take for the resumption of the LHC.

After losing the support of high-temperature superconducting materials and Professor Xu, the detection and discovery of dark matter and dark energy can be said to be far away and there is no hope.

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

Even CERN might fall into ITER's footsteps.

On the other side, Huaguo, Jinling.

The progress of the Planck Plasma Institute is not very clear, and the EU as a whole has not been united in the last lifetime.

But controlled fusion is not a problem that can be solved by manpower.

Manpower can speed up the development and advancement of some conventional technologies, but those top world problems

For example, the mathematical model of plasma turbulence, the first-wall material, or the high-temperature superconducting material with excellent performance are not technologies that can be stacked by manpower.

At least not for a short period of time, and there may be a glimmer of hope for a long period of investment.

Of course, there is only a glimmer of hope.

For example, the mathematical model of plasma turbulence is based on the perfect solution of the NS equation, and the precondition is a millennial mathematical conjecture.

And the latter material is not to mention.

Unless you are lucky enough to make top-notch materials, you can only rely on experience to explore them a little bit.

Although he is concerned about the progress of controlled nuclear fusion in Europe, he is more concerned about the performance of carbon composites synthesized from zirconia under high-energy neutron irradiation after the dawn fusion device is turned on this time.

After all, instead of expecting others to pull their hips, it is the truth that it is better to keep yourself ahead of the curve.

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

Immediately, the full examination was completed, and the steel behemoth lying quietly in the core experimental area let out a soft roar, which was the sound of a powerful electric current flowing through the coil of the field.

Supported by the excellent superconducting properties of high-temperature copper-carbon-silver composite superconducting materials, electrical energy is rapidly converted into a magnetic field, which controls the operation of the high-temperature deuterium-tritium plasma in the reactor chamber.

In the general 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 fusion engineering is the largest project he's ever worked on, not to mention being tasked with solving problems related to the first wall of material.

I heard that this project has spent more than 50 billion RMB so far, and I feel terrible when I think about it.

Even, he can't fully understand what kind of concept 50 billion is.

The cost of the dawn fusion device in front of me is as high as 2.5 billion, not to mention that it has been transformed many times in the future, each time it is tens of millions or even hundreds of millions of dollars.

In case the effect of the zirconia carbon composite material this time is not so ideal, he doesn't know how to face the experimental results.

PS: Yesterday I took my dad to the last trip to Xiangya Hospital for a follow-up, the relevant examinations have been basically completed, the medicine was prescribed, the list was obtained, the time has come to the evening, sent his old man back to his hometown, and only rushed back to Changsha today, so yesterday's update was put today (because the time was urgent, I didn't bring the computer or anything back).

There are two more chapters today.

In addition, I promised you before.,Build a group after dealing with this matter.,It's been done.,There's a link at the end of the chapter.,If you're interested, you can come in and play.。
