Chapter 488: The Hope of Miniaturized Controlled Nuclear Fusion and Aerospace Engines

Ten days is not a long time, but for Xu Chuan, it is enough to solve the problems of HiSilicon and Huaxin.

Originally, he thought it might take one or two months to do it, but after understanding the neural network architecture and the underlying mathematical logic and modeling foundation, he found that this kind of thing is almost entirely based on mathematics.

Although there are some things like chip design mixed in, it is not difficult for him to understand these things.

Days passed one by one, and in the first week after the Lantern Festival, the Sichuan Hai Materials Research Institute came with good news.

With the overtime efforts of the modeling personnel in the institute's computing laboratory, the mathematical mechanism model for the strong anti-magnetic mechanism of KL-66 material was established.

Upon receiving this news, Xu Chuan's eyes brightened.

Superconducting materials with strong critical magnetic fields are one of the cores of miniaturized controlled nuclear fusion and aerospace engine systems.

Only when the critical magnetic field breaks through the original scope can it provide a stronger confinement magnetic field and acceleration magnetic field.

The mathematical mechanism model for the strong anti-magnetic mechanism of KL-66 material is undoubtedly the most critical beginning.

After deploying the experimental arrangement, Xu Chuan also happily accelerated the speed of solving mathematical problems.

After solving the problems of HiSilicon and Huaxin, the next step is his own.

The development of aerospace is the first step towards space and the deep space of the distant universe.

After staying up for two nights and speeding up the problems of HiSilicon and Huaxin, Xu Chuan handed the answers and methods to Mao Shun and quickly rushed to the Chuanhai Materials Research Institute.

The breakthrough in the chip field is not his credit.

Using mathematical ability to help HiSilicon and Huaxin solve problems is just icing on the cake.

But Xu Chuan is still very happy about it.

After all, technological breakthroughs cannot rely on one person.

This is reality, not a novel, and he can't drive the development of all fields by himself.

Unless, like in the novel, he is given a universal system and a thousand years of life, he may have the opportunity to touch and familiarize himself with every field.

Just like the development of chips, this can be said to be a field that is as complex as controlled nuclear fusion technology.

From design, manufacturing, packaging, and testing, each link has derived numerous branches.

Let alone other things, just the manufacturing link, a lithography machine, is enough to block most countries.

Although AMSL can produce the most advanced EUV lithography machine in the world today, it is not the achievement of Windmill Country alone.

This jewel in the crown of industry is the result of the joint efforts of more than a dozen Western countries and dozens of top companies to complete the research and development and manufacturing.

It is naturally difficult for China to pursue the results that surpass more than a dozen countries on its own.

So for the development of science and technology, Xu Chuan naturally hopes that more people will enter this field.

All the way to the Chuanhai Materials Research Institute, Xu Chuan called Fan Pengyue, and the master Xiong quickly rushed down.

"What's the situation?"

Looking at the senior brother wearing a familiar white coat, Xu Chuan didn't waste any words and asked directly.

Fan Pengyue reported briefly: "The model has been established, and the mechanism of high-temperature copper-carbon-silver composite superconducting materials has also been introduced. We are currently doing simulation experiments to see if we can find a way to improve the critical magnetic field of superconducting materials through the model."

"Take me to see it first."

Xu Chuan nodded, and without saying much, he walked towards the laboratory.

It is not so easy to improve the critical magnetic field of superconducting materials. Since 1911, Kamerlingh Onnes discovered that mercury has zero resistance in an extremely low temperature environment of 4.2K.

The superconductivity phenomenon has attracted widespread attention in the physics and materials science community. A large number of researchers have invested in the research and development of new materials with high current carrying capacity and the research boom of revealing the mechanism of superconducting current transmission.

But to this day, superconducting materials still have not made much breakthrough.

If he hadn't brought high-temperature copper-carbon-silver composite superconducting materials, the current scientific community would still be far from the large-scale application of high-temperature superconducting materials.

As for how to improve the three critical properties of superconducting materials, that is, superconducting properties, it is still a cutting-edge discovery in scientific research.

Although researchers today can improve the critical magnetic field strength of some superconductors by controlling the microstructure of superconductors, adding doping elements, and superimposing magnetic field strength.

But it is still a huge problem for the critical magnetic field of superconductors themselves.

So even if the theoretical work has been done, Xu Chuan dare not say that he can 100% produce superconducting materials with high critical magnetic field strength.

In the laboratory, the computational model carrying the strong anti-magnetic mechanism of KL-66 materials is running on the supercomputer of Nanjing University.

Through the underlying mathematical architecture, the supercomputer is simulating the inversion symmetry of electrons in the Fermi arc state.

In this way, the Cu atoms in the high-temperature copper-carbon-silver composite superconducting material are introduced into the position of the C atoms to form stress deformation, which in turn produces non-trivial quantum phenomena and promotes the generation of magnetic traps.

In theory, it is no problem to use this method to improve the critical magnetic field of high-temperature copper-carbon-silver composite materials.

But in fact, for materials such as superconductors, any slight change will bring about a chain reaction.

So when the critical magnetic field is increased, it is bound to cause changes in other properties, such as the upper limit of the critical current intensity, the reduction of the critical temperature, etc.

Of course, it is also possible to increase.

After all, the experimental results have not come out, and no one can say how this material will eventually change.

However, in Xu Chuan's view, the possibility of other superconducting properties decreasing in the direction of low performance is far greater than that of improvement.

But as long as the reduced performance is within an acceptable range, it is enough.

In the laboratory, Xu Chuan looked at the real-time logs generated when the computational model was running for a while, then looked at Fan Pengyue and asked, "Speaking of which, how is the supercomputer I asked you to prepare at the end of last year?"

Fan Pengyue: "I have arranged for someone to handle it. I originally planned to find IBM to make a supercomputer in the field of computing materials. After all, IBM is very good at this."

"But after discussion and communication, because of security and confidentiality, we re-contacted Huake Suguang in China and are discussing customization with Huake."

"The current estimated funding is around 1 billion."

Hearing this, Xu Chuan frowned slightly: "1 billion? Why is it just this little?"

1 billion yuan in funding sounds like an astronomical figure, but in the field of supercomputing, if you want to customize a high-performance supercomputer, it is far from enough.

Take the supercomputing center "Tianhe-2" built in Yangcheng ten years ago, for example, its cost reached 2.5 billion.

Although supercomputers built by individuals and private enterprises do not pursue performance beyond national supercomputing centers, 1 billion yuan in funding is indeed not enough in his opinion.

Fan Pengyue smiled and said, "The total cost is more than 1 billion. The total cost of the customized supercomputer negotiated with Huake is about 3.5 billion, which is about 3.5 times the 1 billion budget."

"But our Chuanhai Materials Research Institute is a key science and technology innovation enterprise supported by the state. It not only has preferential tax policies, but also various subsidies when building such large scientific research equipment."

"Not only direct scientific research funding subsidies, but also subsidies that can reduce prices when purchasing and building such equipment."

"So after all the calculations, we only need to pay less than one-third of the funds to build the supercomputing center, and the rest is subsidized by the state or borne by Huake."

Xu Chuan thought about it and finally remembered that after the nuclear waste project was completed, he was given an application document to include the newly built Chuanhai Materials Research Institute in some policy.

He didn't pay much attention to it at the time, but today he found out that this thing is so exaggeratedly subsidized?

The computational model carrying the strong anti-magnetic mechanism of KL-66 material has been running on the supercomputer of Nanjing University for four days. Xu Chuan waited for two more days in the research institute before the simulation test results came out.

After receiving the data sent back by the supercomputer of Nanjing University, Fan Pengyue came to him as soon as possible.

Xu Chuan: "What's the result?"

Fan Pengyue said quickly with excitement on his face: "From the simulation results, it is theoretically successful! The critical magnetic field is greatly improved!"

Xu Chuan took a deep breath and did not continue to ask questions. He quickly came to the printer room.

The printer was buzzing.

Soon, Xu Chuan got what he wanted, the simulation test results of introducing strong anti-magnetic mechanism for high-temperature copper-carbon-silver composite superconducting materials.

Holding the information, Xu Chuan did not return to his office, but flipped through it directly in the laboratory.

One by one, the data charts and forms continued to appear in his pupils.

"Cu that crosses the Fermi level is far from being filled in the flat band. Theoretically, this should be formed by the hybridization of Cu orbits and C 2d orbits."

"At the bottom of the conduction band and the top of the valence band, the Cu atoms have spin polarity after the simulation of the introduction of holes. From the results, this new material has become a bipolar magnetic semiconductor at room temperature. It's interesting."

Touching his chin, Xu Chuan flipped through the materials in his hand.

What surprised him was that, from the simulation results, after special nano-methods were used to adjust and introduce additional Cu atoms to occupy the orbits originally formed by the hole effect, the properties of the copper-carbon-silver composite material unexpectedly changed, from the original ceramic-like material to a semiconductor-like material.

This was something he had not expected.

Although many ceramic materials are semiconductors themselves, this property appeared in the high-temperature copper-carbon-silver composite material that he developed, which really surprised him.

After all, after he developed this material in his previous life, he must have gone through many tests and verifications, but he did not find that it still had this property.

It can only be said that this additional change does not know whether it will greatly affect the original superconducting properties.

As for the impact, there must be some.

After all, the properties of the material have changed.

But overall, most of the changed area is the non-superconducting part, which should not cause it to fall directly out of the field of superconducting materials.

After all, it is extremely difficult to synthesize an absolutely pure superconductor, which will contain other phases besides the required superconducting phase.

For example, the superconducting phase in copper oxide-based yttrium barium copper oxide is mainly yttrium barium copper oxide 123 phase, but there is also a non-superconducting 211 phase. The superconducting phases in BSCCO are 2223 phase and 2212 phase, and the critical temperatures of these two phases are different.

The same is true for high-temperature copper-carbon-silver composite superconducting materials. Its main superconductor is composed of a copper-carbon-silver-based composite structure, which is its superconducting phase. In addition to the superconducting phase, there are various other composite structures formed by copper-carbon-silver materials.

These composite structures are not superconducting. It is these non-superconducting phases that are changed by the model.

Using the generation of magnetic wells and cooperating with the original superconducting phase to further improve the critical magnetic field is an academic discourse.

In simple terms, it is to further dope composite materials on the composite material to continue to improve its performance.

The words are rough, but the logic is not rough. Using the characteristics of Cu atoms to form magnetic wells on non-superconducting phases is what he does.

Thinking, Xu Chuan continued to flip through the simulation experiment results in his hand.

After completing the optimization of the material, the supercomputing center of Nanjing University calculated the superconducting properties of the optimized superconductor through first-principles calculations and material calculation models.

The data are listed in the table one by one.

Various conventional properties such as hardness, toughness, phase purity, phase ratio, hardness, and plasticity first caught his eye.

Xu Chuan simply glanced at the common properties of these materials, and his eyes fell on the superconducting properties behind.

[Simulated critical temperature (Tc): 121.6-134.3K]

[Simulated critical magnetic field (Hc): At 152K, Hc can reach 37.4T-42.7TT, and at 77K, Hc can reach a maximum value of 47.268T. ]

[Simulated critical current (Ic): It is estimated to reach 5100A/mm2 at 40T. ]

[Critical current density (Jc): ]

[Thermal conductivity: 5k]

Three critical data appeared in Xu Chuan's eyes.

The critical temperature really dropped from the original 152K to the simulated 121.6K, but the impact was not large, and it was still within the cooling range of liquid nitrogen.

The key point is the simulated data of the critical magnetic field, which increased from the original 20T to 37T, and the maximum value reached 47T, which is almost more than doubled.

"Beautiful! 40T critical magnetic field, this intensity is definitely enough!"

Looking at the A4 paper in his hand that still exudes residual warmth and ink fragrance, Xu Chuan's pupils are filled with joy and excitement.

The huge increase in critical magnetic field undoubtedly confirms his previous theoretical calculations.

If this superconducting data can be reproduced in the next real experiment, there is no doubt that the hope of miniaturized controlled nuclear fusion and aerospace engines has been achieved!

The critical magnetic field of 40T can be easily achieved by superimposing magnetic fields to more than 60T, or even higher.

And this level of magnetic field intensity, whether it is for the confinement of high-temperature plasma or the construction of accelerating magnetic fields, can be greatly improved on the existing basis.

PS: There is another chapter in the evening, but it should be too late before 12 o'clock. I have to check some information and ask for monthly tickets.
