From Almighty Scholar to Chief Scientist

【Two chapters in one】

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.

But soon, Li Gang came back to his senses and said, "Although you can use the Pangu supercomputer now, it doesn't affect your design of the magnetic field circuit of the Dongfang Superring, right?"

Lin Xiao spread his hands: "It doesn't really affect it, but as for the magnetic field circuit, I actually designed it a long time ago, and I have been running simulations on Pangu Chao recently."

"It doesn't matter..." Li Gang was nodding his head, then suddenly his eyes widened and he looked at Lin Xiao.

"?"

"What are you talking about? You have already designed it? So fast?"

"Hmm..." Lin Xiao touched his chin and said, "It can't be said that it has been designed, but I have been making further optimizations based on the simulation of the supercomputer during this period of time."

Li Gang: "..."

How do you manage to say such incredible things with such calm words?

"My Academician Lin, are you sure you're not joking? It's only been a month! You've already designed it?"

According to Li Gang's original idea, he has already made plans to wait a few more months before Lin Xiao has finished optimizing.

In the end, Lin Xiao told him back that not only the design was completed, but even the details are being polished now?

No matter how he thought about it, he couldn't figure out why.

But Lin Xiao smiled, spread his hands and said, "Don't be so surprised, why don't I take you to the office after dinner?"

Li Gang nodded immediately and said, "Okay, I'll go and see after eating."

Although he has been shocked by Lin Xiao many times for so long, he has to be shocked every time, and he can't get used to it at all.

This time, he wanted to see how Lin Xiao optimized the magnetic field circuit within a month.

As for Li Gang's surprise, Lin Xiao just shrugged and continued to eat.

After finishing their meal soon, they left the cafeteria and went to Lin Xiao's office.

After arriving at the office, Lin Xiao turned on the computer and showed Li Gang the running interface of the supercomputer.

After seeing the simulation animation above and the large amount of data that popped up next to it, Li Gang finally confirmed that what Lin Xiao said was true!

He really built this superconducting circuit in just one month!
And Li Gang took a closer look at the above simulation situation, good guy, the simulation has been running continuously for fifteen days.

Of course, this [-]-day continuous operation is an accelerated calculation realized by computing power, not that the program has been running for [-] days in reality.

It's just that, after running for [-] days based on this accelerated calculation, the degree of wear on the inner wall shown above is actually less than one-thousandth!

That is to say, in this simulation, Lin Xiao optimized the magnetic field circuit so that the wear of the plasma flow on the inner wall of the device is almost negligible!
After all, it takes less than 360/[-]th of the wear in [-] days, and about [-]% wear in [-] days a year, and they plan to carry out maintenance every three years, which is equivalent to replacing the inner wall material every three years. As a result, the wear rate of the plasma flow can only reach [-]% at most.

So in this way, you only need to face the radiation damage caused by neutrons with peace of mind.

Seeing this, Li Gang couldn't help looking at Lin Xiao next to him, still feeling very unbelievable.

"How did you do it? It's only been a month!"

But Lin Xiao spread his hands and said, "That's how it works."

"How did you do it like this?" Li Gang still couldn't figure out how to complete so much work in one month.

Lin Xiao sat down on his office chair, put his head in his hands, and said, "Well, Academician Li, you should also know that the existence and smoothness of solutions to the Navier-Stokes equations are Did I prove it?"

"Well, of course I know that."

"So, the plasma flow in nuclear fusion, we can treat it as a compressible fluid, and then calculate it according to the Navier-Stokes equation."

"Well, since I am the prover of this problem, doesn't it mean that I have a relatively deep understanding of the Navier-Stokes equations, so it is not troublesome for me to optimize this electromagnetic field circuit."

"This……"

Li Gang didn't know what to say this time.

At first glance, what Lin Xiao said made sense, but the most important question was how to complete such a large amount of work in one month?

Even if it is calculated using the Navier-Stokes equation, it is not uncommon for them to use this method before. It also requires a lot of effort. For any situation, it is necessary to use the NS equation to calculate again Sometimes it is very complicated, and the equation needs to be rewritten. Even if the mathematics is as strong as Lin Xiao, the workload required is still a lot, right?

After all, the problem that Lin Xiao solved at the beginning was only the existence and smoothness of the solution, not a general solution. Unless it is a general solution, all these workloads can be simplified, right?

But there is no news that Lin Xiao has also solved the Tongjie?
At this time, Li Gang even began to think in his heart, could it be that Lin Xiao doesn't need to sleep at night, and then he can do the avatar technique?

But if Lin Xiao knew the guess in his mind, he would probably praise him for his good guess.

Because, he really relied on the general solution of the NS equation to simplify this problem, so he easily solved the entire optimization problem.

So for him, the problem of line optimization is basically not worried.

Mastering the general solution of the NS equation is equivalent to mastering the mysteries of various fluids in a sense, and plasma fluid is also among them, but if you want to compare ordinary fluids, the variables that need to be added to plasma fluid are Just a little more.

"So, according to what you said, is it equivalent to completing the optimization now?"

Finally, Li Gang recovered from his surprise, and then asked.

Fifteen days of less than one-thousandth of the wear and tear has fully met the expected requirements, or completely exceeded expectations.

Although this is only a supercomputing simulation, not a real scene, there is a high probability that the simulated performance will not be much different from the performance of the real scene. It may even be that in real nuclear fusion, the degree of wear and tear can be even higher. How about lower?

Thinking of this, Li Gang is looking forward to the day of the formal experiment.

On that day, for researchers in the field of nuclear fusion abroad, it is estimated that it will be a dark day.

Of course, if they wait until they really develop nuclear fusion, it will not only bring darkness to the foreign nuclear fusion field, but darkness to everyone abroad.

After all, once they develop nuclear fusion, the world's economic balance will tilt from the other side of the Pacific Ocean, which has the hegemony of the dollar, to them, and even the hegemony of the dollar will become precarious.

After all, the hegemony of the US dollar is based on the hegemony of oil, but when controllable nuclear fusion appears, the position of oil in energy will inevitably be replaced.

For a moment, various predictions about the future situation flashed through his mind, and Li Gang could no longer calm down.

So he stared at Lin Xiao again, waiting for his answer.

But Lin Xiao smiled and said, "No hurry, anyway, we can continue to optimize, don't worry, let me see if I can control the wear and tear to 30/[-]th in [-] days."

"One-thousandth of a wear in 30 days?"

Li Gang stared again, then sighed again.

Want to say something, but don't know what to say.

From [-]/[-] wear in [-] days to [-]/[-] wear in three days, in the past, he would definitely say "greedy", but now...

He waved his hand and said: "Forget it, I don't care, you are the chief engineer and you have the final say. I think I should drink tea every day and go shopping in Jinmen City. I will apply for retirement after the Golden Crow Project is over." .”

"What do you call it in the language of young people? It's bad?"

"Well, I'm screwed."

And Lin Xiao looked at the appearance of the old academician, finally touched his nose, and said, "This should be called lying flat."

"Lie flat?" Li Gang was taken aback for a moment, then said "Oh", and said, "I forgot, academician Lin, you are still a young man, you know better than me."

"It's nice to be young..."

He shook his head, waved to Lin Xiao at last, and walked towards the door of the office.

Looking at this scene, Lin Xiao couldn't help touching his nose, why did he feel like he accidentally hit an old man?
Of course, he also saw a sense of relief from Li Gang's leaving back. Perhaps for this old scientist, this time "laying down" was his willingness to lie down?

Lin Xiao stopped thinking about it, sat down again, and then looked at the data on the computer, and continued to optimize the magnetic field circuit.

……

In the blink of an eye, another month has passed.

And counting, it has already passed two months.

All fusion tungsten plates have been prepared and shipped to the Plasma Institute in Feishi.

Similarly, half a month ago, Lin Xiao had already taken out his optimized circuit, and after half a month, the superconducting circuit of Dongfang Superring had also been rebuilt according to his plan.

So far, all preparations have been completed.

"According to the plan, our experiment needs to be ignited twice. The first ignition is a control experiment. The ordinary tungsten plates and the fusion tungsten plates are arranged crosswise. After ignition, take a look at the irradiation of different tungsten plates. The degree of damage, and then compare."

"The second ignition is based on the premise that the fusion tungsten plates meet the expected conditions after the first ignition, and all internal tungsten plates are replaced with fusion tungsten plates to conduct limit ignition tests."

"Okay, this is all the plan for this experiment, for the rest, please follow the original arrangement!"

"Yes!"

After Lin Xiao announced all the plans for this experiment, everyone started working immediately.

Of course, the most important work is the replacement of tungsten plates.

This work needs to drill into the Dongfang Super Ring, and then install the tungsten plates one by one, but the staff have drilled many times before, so it is not a big problem.

In this way, half of the fusion tungsten plates and half of the ordinary tungsten plates were quickly installed inside.

"Okay, all staff began to evacuate the restricted area, and the first ignition will be carried out soon."

Lin Xiao held the walkie-talkie and gave his instructions.

After a while, a response came from the intercom: "All have been withdrawn!"

"Very well, then, the countdown to ignition begins now."

Lin Xiao said again.

Everyone also held their breath, waiting for the moment when the ignition would start.

"10!"

"9!"

"8!"

"7!"

"..."

At this moment, the entire plasma laboratory has almost fallen into silence, only the countdown on the radio, accompanied by echoes, reverberates throughout the laboratory.

"3!"

"2!"

"1!"

"ignition!"

As the final "ignition" sounded, Lin Xiao pressed the button representing ignition. Of course, it actually turned on the current.

Heating is carried out through electric current, and the temperature is heated to hundreds of millions of degrees. Of course, there are many kinds of heating methods involved. Only with the assistance of various heating methods can it reach hundreds of millions of degrees.

And as the ignition started, everyone also looked at the big screen, which displayed the temperature in the fusion furnace.

I saw the number representing the temperature on the big screen soaring rapidly, from tens of degrees at the beginning to hundreds of degrees, then thousands of degrees, and ten thousand degrees.

The numbers are getting bigger and bigger, which also means that an artificial sun is being born in this device.

What you need to know is that even the surface of the sun is only a few thousand degrees. As for the temperature in the center, it is only 2000 million degrees Celsius, and their temperature is heading straight to [-] million degrees!
This is the great cause of human beings!
In this way, as time passed, the temperature, which was only normal temperature at first, finally reached more than 900 million degrees.

"I'm coming!"

Seeing this scene, everyone in the institute clenched their fists and began to wait.

Finally, the temperature reached 1 million degrees!

And when the temperature reached [-] million degrees, a timer was displayed on the big screen, and it started counting. This was to record how long they could last above [-] million degrees!
At the same time, all the researchers couldn't help but silently read this number.

"1."

"2."

"3."

"4..."

I followed the silent recitation second by second, but the temperature was still rising rapidly, and soon, the temperature finally reached above 1.2 million degrees.

Last time, they burned for 1.2 seconds above 101 million degrees. How long can they burn this time?

Of course, at the same time, the temperature is still rising and has reached 1.6 million degrees.

Seeing this scene, the people present became even more excited.

Can the 1.6 million degrees this time exceed the 20 seconds last time?

Everyone silently counted the seconds again.

"1..."

"2..."

"3!"

"..."

until--

"20!"

"21!"

"22!"

"Breakthrough! More than last time!"

All the researchers cheered when they saw this scene.

They broke through last time!
However, this time, what limit can they reach?
Everyone has great expectations!
