Capital.

After the establishment of the fusion design project, a series of scientific and technological conferences were held.

Among them, the conference on the theory of superconducting technology has attracted much attention.

Technical theory will involve not only technology, but also theory, that is, the future research and development direction and development direction.

In the first half of the superconductivity conference, various institutions still released the latest material technology information, so that the participants could see the application research of advanced elements in various material fields.

Deng Huanshan is one of the most beautiful scholars.

As the head of the Superconducting Materials Research Center, many scholars have surrounded him to inquire about the research of superconducting materials, and the results of the Superconducting Materials Research Center are a new first-order iron-based superconducting materials.

This is the material that Wang Hao recommended to the space agency.

At room temperature, the resistivity of the material named 'CWF-071' is higher than that of silver and lower than that of copper, which means that it can be used as a substitute for conventional wires at room temperature.

In addition, the CWF-071 has a transition temperature of up to 201K, and as the temperature decreases, the resistivity also decreases significantly.

In general, the resistivity of conductors will also decrease with temperature, but the decrease is not large, and the CWF-071 can clearly see a significant drop.

"In the future, CWF-071 will be mass-produced, and it can replace conventional conductors in many environments and act as conductive use."

Deng Huanshan said with a smile on his face, "The ultimate research and development goal of superconducting materials is to achieve room temperature superconductivity. ”

"In the field of superconductivity, there is great potential for upgraded materials, and our next goal is to fabricate superconducting materials with higher transition temperatures......"

He also named the set target data - 230k.

That's a staggering statistic.

230K, that is, minus 43.15 degrees Celsius, close to special zones such as the North and South Poles, can reach this temperature.

In fact, Deng Huanshan and other scholars have subconsciously ignored a question--

Current carrying capacity.

All superconducting materials now used in applications are complex metal compounds, and the conductivity is mainly determined by the metal elements.

In the same way as to achieve superconductivity, the current carrying rate of elemental metals is much higher than that of complex metal compounds.

The resistivity of CWF-071 is lower than that of copper, but the current carrying force is far less than that of copper, and the use of CWF-071 at room temperature requires a thicker wire to be able to maintain the resistance value.

Of course.

If the superconducting state can be realized, its performance will suddenly exceed that of copper, and the problem is that even the development of first-order iron-based superconducting materials has encountered the problem of the limit of transition temperature.

The so-called 'limit of transition temperature' means that in the process of research and development, a special temperature value will be found, and the transition temperature of most superconducting materials cannot exceed this temperature value, and it is difficult to exceed too much if a small number can be crossed.

It turns out that conventional elements study superconducting materials, and the limit of the transition temperature is about 180K.

Now with first-order iron, it has risen to 200k.

At the meeting, scholars from the Key Laboratory of Superconductivity of the Academy of Sciences talked about the "limit of transition temperature" and made a research report.

Many scholars think about it.

Wang Hao listened with great interest, and the report he prepared was to explain the research direction of superconducting materials, to a certain extent, that is, to clarify a method to break through the limit problem.

"Advanced Elements and Material Crafting Techniques!"

When Wang Hao came to the stage to make a report, he talked about two points, one is the upgrade element, and there is too much to talk about the upgrade element.

"We can see that after the application of first-order iron, the limit of the transition temperature increases. Many materials teams at home and abroad have developed superconducting materials with a critical temperature close to or beyond 180K. ”

"Due to the limited current carrying force, most materials have no application value."

"But in any case, the discovery of the upgraded element has raised the limit value of the transition temperature."

"In the process of studying the upgraded elements, we found that compared with the conventional elements at the same temperature, the activity of the outer electrons of all the upgraded elements will increase, in short, the resistivity will decrease."

"So we can simply infer that second-, third-, or higher-order metal elements may have superconducting properties at room temperature."

"Of course, that's not possible for the time being."

"We also have a direction, which is to manufacture high-current force-bearing metal materials that are close to superconducting properties at room temperature."

In the end, what Wang Hao said was related to dense materials.

Dense materials can increase the density of materials and effectively reduce the resistivity of metal materials.

They have produced dense silver, which has more than five times more resistivity at room temperature than conventional human silver.

This material is certainly very valuable as a conductor.

Unfortunately, the dense silver produced has a certain degree of radiation and cannot be used as a conventional material, and the annihilation force field experimental team is hoping to produce dense silver without radiation by continuously reducing the strength of the annihilation force field.

……

After the conclusion of the conference on superconductivity technology theory, many people were talking about Wang Hao's report.

The general superconducting materials conference talks about the manufacturing technology of superconducting materials, either to show the latest superconducting materials, or to talk about the research and development direction of superconducting materials.

In the field of superconductivity, the ultimate goal is to achieve room temperature superconductivity.

Wang Hao's report felt a bit 'unreasonable', he talked about the advanced elements and material manufacturing technology, directly from the underlying element base to reduce the resistivity of materials, improve the transition temperature limit.

But what he said made a lot of sense.

Many scholars have sighed, "Therefore, the realization of room temperature superconductivity in the future does not depend on the research of superconducting material technology, but on the research of annihilation force field." ”

"If you want to completely conquer a technology, you have to get out of the technical field to do it."

"That's the norm anymore."

"How many people and how many institutions are studying superconducting materials, just from the composition of elements and manufacturing methods, it is impossible to achieve superconductivity at room temperature."

"What Academician Wang Hao said is too reasonable."

"I'm really looking forward to seeing that kind of high-end element, but I just feel ...... There is no hope for a short time ......"

“……”

This is the case in the field of superconducting materials technology.

It is almost impossible to solve the problem of extreme values of the transition temperature if only conventional studies are relied upon.

Now with first-order iron materials, 200K is close to the upper limit of the extreme value, and I feel that most materials close to the transition temperature of 200K will have various problems, and it is difficult to put them into application.

In terms of application direction, the most widely used is the 141K CW-019.

This is also the signature of superconducting materials industry company, which has the most production and most extensive applications, and has been used in many fields.

A large number of materials institutions have proved with experimental research that it is difficult to break through the extreme problem of superconducting material technology alone, and it is necessary to find ways in other directions.

Wang Hao provided a good idea and a good direction.

It's a pity that most people can't participate in the research, and they can only learn about it.

Wang Hao attaches great importance to the problem of materials, and they have already given a definition of dense first-order iron materials, that is, 'future iron elements'.

'Future Iron Element', named Iron 56 β First Order.

β represents the second order, 56 represents the atomic mass, and the conventional dense material is named the first-order α material.

For example, conventional first-order iron is first-order α iron 56.

On the way back to Xihai University, Wang Hao also thought about the research in the direction of 'future elements', "It seems that the experiment must be started, and the short-term goal is to study several isotopes of iron, hoping to find a future iron element without radiation." ”

This research is related to the technology of strong annihilation force fields.

The 'Future Element' is not affected by specific phenomena, and can support the creation of a high-strength strong annihilation field.

……

After returning to Xihai University, Wang Hao continued to pay attention to the research of the F-ray experimental group and the annihilation force field experimental group.

Both experimental groups are doing well.

At the same time, he will also be involved in the nuclear fusion design project, starting with the formation of the main team of the design project.

This work is still dominated by Tang Jianjun.

Tang Jianjun is very enthusiastic about the research of nuclear fusion, he is already more than 60 years old, and he is still working energetically.

With the support of the Ministry of Science and Technology, the Academy of Sciences, the International Science Foundation and other institutions, the project team quickly decided on the location of the old government office building in Xihai City.

The old government office building is designated as a control area.

The name of the team is called 'Nuclear Fusion Device Design Group', which sounds very low-key, but it has more than a dozen academicians, dozens of researchers, hundreds of engineers, and three academicians stationed in the main research base.

Among them are Deputy Chief Designer Tang Jianjun, Zhou Dongwei of the Institute of Nuclear Physics, and Gong Yunwei of the Institute of Materials of the Academy of Sciences.

There are only two dozen researchers below for the time being.

Two dozen researchers may sound like a lot, but they are too small for a fusion project.

Within the nuclear fusion device design group, a number of professional groups have been set up, including the main design group, the material group, the power group, the magnetic energy group, the energy demonstration group, the power group, the computer group, and so on.

The main design team is directly responsible for Wang Hao, and it is also the core team, responsible for the design of the main framework of the nuclear fusion device, and will assign R&D work to other research groups.

Several academicians are in the main design group.

The material group is the largest.

Half of the energy in the design of the nuclear fusion device is focused on solving the material problem, and the materials group naturally has the most researchers.

The person in charge of the energy demonstration group is Wang Baichuan, whose main job is to do internal energy intensity, reaction intensity and related demonstration and experimental research.

The magnetic energy group is responsible for the outer spiral magnetic field, and the work is to combine the design of the tokamak's 'imperfect magnetic field' with the outer magnetic field of the strong annihilation force field.

Wait a minute.

Wang Hao is responsible for the main design work, and the team also arranges its own manpower, namely Ding Zhiqiang, Yan Jing, Xiao Xinyu and Luo Dayong.

In the past few months, Ding Zhiqiang has been working in the Anti-Gravity Morphology Research Center, participated in a lot of experimental research on the front line, and has an intuitive understanding of the annihilation force field experiment.

This time, the design of the nuclear fusion device also involved Ding Zhiqiang.

Wang Hao is looking forward to Ding Zhiqiang's 'inspiration' contributions to help advance the design of the nuclear fusion device."

Yan Jing and Xiao Xinyu both belong to 'their own people'.

They are all old men from the Anti-Gravity Morphology Research Center, and they have an in-depth understanding of anti-gravity fields, thin layers of strong annihilation force fields, and F-rays, and can be of great help in both experiments and designs.

Wang Hao asked Yan Jing to join the design team, and he also had the idea that he wanted her to be an 'assistant'.

Chen Mengmeng is Wang Hao's first assistant, but she also has a lot of work, and most of the time she has to help deal with information and scholar exchanges, so she can no longer participate in design work.

Yan Jing joins the design team, can be responsible for the planning and recording of meetings, and can also report the research progress of other groups at any time, etc

Luo Dayong is incidental.

Wang Hao just wants to have a few more 'own people' in the design team, not all old academicians and researchers, and Luo Dayong, who focuses on theoretical work and has in-depth research on complexity argumentation, may be able to promote the design work.

Of course.

This must have nothing to do with Zhu Ping, who was so enthusiastic that it gave Wang Hao a headache.

After the framework of the nuclear fusion device design team was built, Wang Hao also came to the research base, convened all the members of the design team and the leaders of each research group, and held the first research meeting.

Many people who heard the news subconsciously thought that it was a personnel meeting, and the research team had just been formed, and there was still a shortage of manpower, that is, everyone got together to get to know each other, and then said a few words of encouragement to mobilize everyone's enthusiasm for work.

That's all.

When they entered the conference room, they found that it was completely different from what they had imagined.

On the projection screen of the conference room, a frame of the design has appeared, which is a large circular installation, and many pipes are painted underneath.

When it came to the design work, they knew that the framework might be a fusion device.

After everyone came to the conference room, Wang Hao also sat on the main seat and said, "Normally, the research group has just been formed, and everyone may have just come to Xihai, and the first meeting is to get to know each other."

"We're not doing research against time, and we don't seem to be in a hurry."

"But I want the design to be completed quickly, to move on to the next step, and to be able to build a fusion device faster."

"Research isn't a race against time, but I don't like to waste time."

"Let's come and see ......"

After Wang Hao finished speaking, he directly entered the state of explanation.

All the participants were a little confused, they didn't expect to go straight to work at the first meeting, and they weren't even prepared for it.

They have been sighing in their hearts, "It is worthy of Academician Wang Hao!" ”

"Resolute!"

"I don't procrastinate at all, maybe it's this kind of work attitude that can complete so much research......

Yan Jing, Ding Zhiqiang, Luo Dayong and others have long been used to it.

Wang Hao has always been like this, doing research is doing research, getting to the point cleanly, and finishing the research quickly is the right thing.

Nothing else matters.

Many people in the outside world, and even in research groups, think that the fusion design work is a long-term study that could last for several years.

But they think......

Perhaps, soon.

It's hard to say how fast.

"If you don't encounter unsolvable problems, it will take about a year...... Enough, right? Xiao Xinyu thought about it and made a judgment.

"Half a year, almost." Yan Jing is like this.

Luo Dayong didn't speak, no one knew what he was thinking.

Ding Zhiqiang......

He was clutching his head and pondering a painful question, "Why did I join the fusion design team?" When will I be able to get out of the clutches of Teacher Wang Hao......"
