From Almighty Scholar to Chief Scientist

"This, this, this...isn't it incredible?"

Zhang Ran obviously also heard this shocking result, so he was also dumbfounded.

Just kidding, he has been engaged in neutron irradiation for so many years, which material has he not seen?

And in the neutron irradiation experiment, which of these materials did not show that they were easily smashed to pieces by neutrons?

That is to say, a small number of materials such as tungsten plates can still persist for a while, but it is impossible to have no loss at all.

Results now?

This time, there is really no loss at all. As a scientific view of [no material can resist neutron irradiation], he only feels that his scientific view has been greatly challenged.

"This... how did you do it? What kind of material is your material?"

He turned his head with some difficulty, looked at Lin Xiao next to him, and his tone was full of thirst for knowledge.

When he studies neutron irradiation, he also studies materials, so he also really wants to know the principle of this material.

It's just that Lin Xiao didn't seem to hear his question. He supported his right arm with his left hand, and then pinched his chin with his right arm, thinking about the problem.

Seeing this, Zhang Ran also sighed, shook his head, put away his thoughts of continuing to ask Lin Xiao, and probably Lin Xiao would not tell him.

This kind of material can already be called a state secret. Zhang Ran is very clear that since the new type of tungsten plate in this experiment can achieve a DPA value of 0, it means that it is more suitable for the inner wall material than the tungsten plate. up.

The preparation method of this material must be a state secret, just like a room temperature superconductor.

Thinking of this, Zhang Ran couldn't help but look at Lin Xiao a few more times. It was so difficult for everyone to research materials, but why did Lin Xiao act like he played the cracked version?

This time he didn't feel like Miss Li again.

And just when he shook his head and sighed, Lin Xiao finally came back to his senses.

However, there was still no expression of joy on his face.

At this time, a researcher walked over excitedly and asked, "Academician Lin, do you want to continue the experiment?"

Lin Xiao looked flat, and said, "Well, we can continue."

"Ok!"

The researcher responded immediately, and then immediately returned to his post, probably because the material was so novel that they, the researchers, wanted to see more.

However, these researchers basically did not notice that Lin Xiao was not as excited as they were, and as the developer of this material, Lin Xiao should have been the happiest.

Of course, Zhang Ran noticed it, so he asked: "Academician Lin, what's the matter? Is it possible that this kind of result can't satisfy you?"

"This is not true. Meeting expectations is meeting expectations, but not all expectations."

Lin Xiao said.

"Although your neutron irradiation can indeed simulate the environment of neutron bombardment, it cannot simulate the energy of neutron bombardment in real nuclear fusion."

"Given the self-limiting effect of tungsten, it didn't meet all my expectations."

"That's right, it's true."

Zhang Ran nodded. Indeed, as Lin Xiao said, the neutrons emitted by their neutron irradiation equipment could not be as real as in a real nuclear fusion reaction.

The reason why metal tungsten is often selected as the inner wall material in controlled nuclear fusion experiments is because of the self-limiting effect of metal tungsten, which can prevent the tungsten plate from being worn out in the face of long-term neutron bombardment There are too many, that is, the particles with a temperature of more than [-] million degrees will not make it too miserable.

So this experiment can't explain much.

It’s like wanting to destroy these tungsten plates, the energy needs to reach at least 100, but in the radiation test, the energy of neutron bombardment is only 60 at the highest, which makes it impossible to break through this value no matter how bombarded. The internal structure of this special tungsten plate cannot be destroyed.

"So, don't you intend to...?"

Thinking of this, Zhang Ran suddenly thought of a possibility.

Lin Xiao smiled and said, "Yes, let's see its final performance in the controllable nuclear fusion first."

Zhang Ran's eyes widened suddenly, Lin Xiao actually planned to do this!

At this time, Lin Xiao patted him on the shoulder and said, "I'm going back to the hotel first, so I'll trouble you to take a look here first."

"Oh... good!"

Zhang Ran came back to his senses and responded quickly, but at the same time, he also had great expectations for what Lin Xiao said.

If Lin Xiao really intends to directly test the strength of this new type of tungsten plate through nuclear fusion experiments, it is obviously the most appropriate.

And in this way you can also find the limit of this tungsten plate!

Take a look at how much energy it can withstand neutron bombardment!

Zhang Ran is looking forward to hearing a news that will make people all over the country excited!

……

After Lin Xiao left the research institute, he called Li Gang and told him about the results of the experiment.

No need to think too much, Li Gang of course also showed great shock.

"What? After one hour of the neutron irradiation experiment, the radiation damage value is 0DPA?" Li Gang exclaimed in disbelief, "Oh my God, today is not April Fool's Day, Mr. Lin, are you sure it is?" Really? Isn’t there something wrong with the testing equipment?”

Lin Xiao said with a smile: "Could it be fake? There must be no problem. The DPA value of the ordinary tungsten plates in our control group has been detected. It is the same as last time, and it is still around 0.024."

"It's… okay."

Li Gang accepted this fact with difficulty, but Lin Xiao could still hear Li Gang muttering "this is unscientific" and "how is it possible?" through the microphone.

Lin Xiao smiled, didn't care too much, and said directly: "Okay, Academician Li, don't get too excited. The experiment this time is just ordinary neutron irradiation, not nuclear fusion neutron irradiation."

"So, my next plan is to directly test the ability of this new material in nuclear fusion. In other words, what you said last time, leaving the Eastern Super Ring to me for experiments, should be promised. .”

And Li Gang also came back to his senses, and after hearing Lin Xiao's words, he suddenly said excitedly: "Of course, I have been waiting for this day for a long time!"

"And your new material is so strong, this time, we can definitely make history!"

"Wait, I'll go find Song Tao right away and prepare the Dongfang Chaohuan within a week."

"Then hang up first..."

"Hey hey!" Lin Xiao shouted quickly, not knowing whether to laugh or cry: "Don't be so anxious! We still need to prepare in advance, a week is too fast, just transporting the tungsten plate from Jinmen to your Dongfang Chaohuan At least another week."

Li Gang also realized that he was too excited just now. Of course, there is nothing he can do about it. He is so old and has almost dedicated his life to the nuclear fusion business. I'm a little excited.

"Okay, I'm really in a hurry, so tell me about your arrangement."

"Well, let's first..."

Lin Xiao then talked about his plans for the future.

After Li Gang listened to it, he was surprised by one of them: "Do you want to optimize the magnetic field layout of our Eastern Hyperloop?"

"Well." Lin Xiao said: "After all, we can't wait to replace all the superconductors in the Eastern Superring with our room temperature superconductors. The niobium-titanium alloy used in the Eastern Superring is still too weak to provide an electromagnetic field, so Let me first optimize your Dongfang hyperloop magnetic field circuit, which is also more convenient for our experiments."

"What about the circuit optimization of your conch-type nuclear fusion device?"

Lin Xiao said with a smile: "Mathematics is common. After helping Dongfang Chaohuan to optimize, I naturally understand the conch-style optimization method better."

"That's it... OK, I see, I'll make arrangements now."

"Ah."

Putting down the phone, Lin Xiao heaved a sigh of relief. Next, it was the critical moment.

The experiment on the Eastern Super Ring will be the moment that decides everything!

Chapter 435 Ignition!break the limit!

The arrangement for the next experiment has basically been determined, that is, to use their particle accelerator to produce more special tungsten plates to prepare for the verification on the Eastern Super Ring!

It takes two months to produce the total amount of tungsten plates required for Dongfang Chaohuan, which is almost half of the conch device designed by Lin Xiao.

This is mainly because the volume of the Dongfang Super Ring is still relatively small. Even if it can really achieve stable nuclear fusion, the energy it can provide is not enough to meet all the electrical energy required by the entire Beijing-Tianjin-Hebei economic circle.

Of course, the inability to provide it is mainly due to technical problems. In theory, even a disc with a diameter of less than ten centimeters can achieve nuclear fusion, but the most critical problem is how to achieve nuclear fusion in this ten-centimeter disc. , to create a magnetic field strong enough to confine the flow of plasma that undergoes fusion reactions inside.

Obviously, to achieve this point, the magnetic field strength has to be at least hundreds or thousands of tesla, and it is impossible for any current superconductor to provide such a strong magnetic field without quenching.

After all, the black technology contained in Iron Man's luminous disc less than ten centimeters cannot be produced in reality.

Of course, for now, they don't need to pursue that level of technology, and they will first give out a commercially available nuclear fusion reactor.

Therefore, two months later, when all the tungsten plates are produced, it is time to prepare for the real chapter.

Of course, there was another more important thing during the period, and that was Lin Xiao's optimization of the magnetic field line of the Dongfang Hyperloop.

To some extent, this point is more important for this experiment than the production of special tungsten plates.

Although the general direction of the magnetic field of the tokamak device is fixed, the magnetic field line is not fixed, which means that the line of the current-carrying conductor that provides the electromagnetic field can be designed more specifically.

Whether this design is good or not is related to the stability of the entire reaction.

This is because in the plasma flow of controlled nuclear fusion, any slight disturbance may cause a subsequent chain reaction, which will greatly reduce the life of the device.

For example, originally these plasma flows have been controlled in the center of the reaction device to carry out a stable reaction, but two of them collided with each other, and after colliding with each other, they collided with other plasmas, so in the end, the plasma The flow will become turbulent again, so that these equally high-energy plasmas will hit the inner wall, causing damage, and the life of the device will naturally be reduced.

So at this time, careful design is required so that the plasma flow can only participate in the reaction rather than the destruction.

In this way, for their experiment this time, the error of the experiment can be reduced. After all, this experiment is to verify the performance of the special tungsten plate under the neutron bombardment of the nuclear fusion reaction, and the bombardment of the plasma flow Obviously there will be errors.

Of course, in addition to this purpose of this experiment, they also have another purpose, which is to see how long their Eastern Super Ring can light up the sun this time!

The best results achieved by Dongfang Super Ring are the repeatable 1.2-second plasma operation at 101 million degrees Celsius and 1.6-second plasma operation at 20 million degrees Celsius.

This kind of achievement is good, at least in the world, it is very good, but at the same time, it is also very bad.

Because whether it is 101 seconds or 20 seconds, compared with the ultimate goal that requires long-term operation to generate electricity, this time is not enough at all.

This is not to mention sending electricity for such a short period of time, which is even more worthless compared to the resources invested.

But this time, they replaced it with a material that can achieve complete resistance in ordinary neutron irradiation, coupled with Lin Xiao's optimization of the electromagnetic field circuit, how long can they resist this time?

Everyone at the Plasma Institute is looking forward to it.

However, during this process, some people really wanted to know how Lin Xiao would optimize the route.

Especially in just two months.

The superconductor circuit of the entire Eastern Superring is quite complicated. Even a slight movement of the ground may affect the overall magnetic field, so how to optimize the circuit has a lot to do with it, and it can almost be said that it affects the whole body.

Moreover, the circuit they originally designed has reached a very good level. If it is further optimized, where can it be optimized?

Many people are curious.

Li Gang was also included.

……

"It's been a month, and this month's 250 fusion tungsten plates have been shipped to Dongfang Chaohuan."

In the cafeteria of the Golden Crow Project Research Institute, Lin Xiao and Li Gang were sitting and eating together. After a few mouthfuls, Li Gang said something.

Fusion tungsten plate refers to the new type of tungsten plate. Why is it called so? It is because they all put their hope of successful fusion on this tungsten plate, so they use this name to express their expectations. up.

"Ah."

Lin Xiao nodded, "Just follow the time, don't worry."

Li Gang smiled, "I'm not in a hurry, but the problem is on your side."

"Optimizing the route shouldn't be that simple, right?"

Lin Xiao smiled and said, "It's really not very simple, but it's not a big problem. I have a VIP account of Pangu Supercomputing here."

Li Gang was taken aback, "Pangu super calculation?"

"Ah."

Lin Xiao nodded.

A surprised expression suddenly appeared on Li Gang's face: "Didn't you just build this? You already have an account?"

Lin Xiao spread his hands and said, "Theoretically, Pan Guchao calculated the most money from our Dingguang Research Institute. Of course I have an account."

A look of envy suddenly appeared on Li Gang's face.

The Pangu supercomputer, which is known as the strongest supercomputer of human beings, has attracted all kinds of attention from the scientific community since it came out, including the people in their plasma institute. After all, the research on the plasma fluid in the tokamak device In the problem, the use of supercomputing to assist research is an indispensable means.

So when the news of the Pangu supercomputer first came out, it had already attracted their attention, not to mention the amazing computing power that Lin Xiao showed when he first used it, and even showed a kind of It will regain the momentum of the world's number one supercomputer.

After such a long time, the Pangu supercomputer has been built some time ago, but it has not yet been opened for use. After all, it still needs a period of internal debugging.

However, Lin Xiao's Dingguang Research Institute is the party that pays, so Lin Xiao can naturally use it in advance.
