Technological Supremacy Chapter 507: Fusion! fusion! fusion! (4,600 words)

“Go!”

Following Luo Jia’s order, the double-helix stellarator fusion reactor, located 117 meters underground, started its first operation.

Fusion takes place inside the reaction furnace, and people cannot see the reaction process from the outside. The most intuitive manifestation is the constantly beating temperature on the screen.

Five thousand degrees!

Twenty thousand degrees!

One hundred and fifty thousand degrees Celsius!

The temperature is rising rapidly, and it will soon exceed the limits of ordinary people’s imagination.

The boiling point of water at standard pressure is 100 degrees Celsius, the melting point of iron is 1,535 degrees, and the melting point of tungsten is 3,422 degrees. The temperature of controllable fusion can be easily Reach tens of millions of degrees Celsius, or even hundreds of millions of degrees Celsius.

All the materials known so far cannot resist the high temperature of hundreds of millions of degrees. According to normal logic, because the outer wall of the reactor cannot resist the high temperature, it will be melted soon, eventually leading to disaster.

However, this is precisely where science is interesting. To explain it with the simplest example, it is taking a bath.

As we all know, the temperature of water vapor is 100 degrees Celsius. When we take a bath, white water vapor curls up, passes over our body, and forms a layer of white water mist on the mirror. During the bath, We are exposed to 100-degree water vapor, but are we harmed?

Obviously not, because there is a problem of energy density involved.

Hot water of more than 50 degrees can scald you like a pig, but you can bear the steam of 100 degrees. It is precisely because the density of steam and water is different that the results are also different.

Of course, assuming you die and enter the relatively dense water vapor, after about 30 minutes, the delicious steamed human beings can be served on the table.

In addition, the shell of the fusion reactor is not in direct contact with the high-temperature plasma. The plasma is confined in the longitudinal magnetic field. , then the charged particle has a motion component along the direction of the magnetic field line, and the circular motion will become a spiral motion.

Anyway, charged particles cannot fly out of the plasma membrane. Only neutrons can fly out, which is the phenomenon of neutron bombardment mentioned by Luo Jia before. The solution to neutron bombardment depends on more advanced reactants and supercomputers Forcibly decipher the laws of motion and make fine adjustments to the magnetic field.

In short, the plasma is confined in the vacuum chamber, and the heat is also confined in it. Although the controllable fusion temperature is exaggerated, it is very safe.

“One million degrees Celsius has been broken!”

“So far, there have been no problems with the reactor! The core temperature is steadily increasing!”

“As expected of Xingchen Technology, you know, this is their first fusion experiment, and they can do it to such a degree!”

Everyone was surprised and said that failure is the mother of success. However, this law does not seem to apply to Xingchen Technology. They are a group of men with overdeveloped minds, and they are also a group of lucky men. The smoothness of the first test was beyond everyone’s expectations.

“After all, it is the design of energy civilization. The double helix stellarator has already existed in energy civilization. It has been more than four epochs. It is a very mature product. Even if it is weakened according to the earth’s technology, there will be no problem. Yes.”

“However, the double-helix stellarator is not the strongest technology of energy civilization. It is said that before the era of war, energy civilization used antimatter as an energy source, and the power of antimatter is far more than that of controllable fusion. Unfortunately, in the later era of civilization annihilation, all technologies related to antimatter disappeared mysteriously.”

Luo Jia was thinking in his heart that he didn’t take everyone’s surprise seriously, and if he copied the technology of energy civilization and made mistakes, Luo Jia should doubt his own IQ.

“Three million degrees Celsius! Mr. Luo, how do you measure the fusion temperature?” Someone asked.

Luo Jia smiled slightly, “We can’t use a resistance thermometer to measure things like nuclear fusion. The way we use it is to shoot laser light into the plasma. After all, the temperature is different, the optical properties are different, and the spectrum is also different.”

“Look at you asking this question, Star Technology has a lithography machine production line, and their optical department has long been the number one in the world!” Someone praised the optical department of Star Technology.

“I can’t be wrong. Senior Lu Chengfeng is the leader in the domestic optical field, and Zhang Yuechuan’s strength is obvious to all. As for the laser project, I heard that Wen Chengling has been in charge of it for the past two years.”

“Wen Chengling? Two brothers, one engaged in life sciences, the other engaged in lasers, those two brothers who disappeared for some reason?”

“It’s them. I heard that because their parents died in Amazon, they couldn’t think about it for a while, so they lived in seclusion in Brazil. They were just invited back by Xingchen Technology two years ago.”

“This is the attraction. Star Technology is now the company that scientists in the world most want to join. There is no one. Even Japanese and Korean scientists have come here. Luo Jia and the others have also made contributions to the East Asian Union.”

Everyone whispered, everyone praised Xingchen Optics, but they didn’t know much about the Wen family brothers, mainly because the Wen family brothers deliberately concealed the past. The unbearable sad past has also completely changed the fate of the two geniuses, turning the two once simple scientists into one of the few ruthless scientists among scientists, who dared to step forward on the ground full of corpses and blood without taking any The hesitant kind.

“Ten million degrees!” A few minutes later, someone exclaimed again.

About the high temperature required for nuclear fusion, there is actually no fixed number. The core temperature of the sun is 15 million degrees, which is lower than most artificial fusion devices, but can you say that the temperature of the sun is not high enough?

To understand the issue of nuclear fusion temperature, we first need to know what nuclear fusion is.

Nuclear fusion is a process in which light nuclei collide with each other and fuse with each other through strong interactions to become heavy nuclei. Since the binding energy of heavy nuclei is greater than that of light nuclei, a large amount of energy will be released.

So how does nuclear fusion happen?

As we all know, the nucleus is positively charged, and electrons surround the nucleus at lower temperatures, and electrons are more in the way. To do something, it is best to get rid of the light bulbs around you first, so at this time, you need to resort to the first condition of nuclear fusion, plasma.

Plasma is the fourth state of matter. In a high temperature state, the nucleus will be separated from the electrons, and the light bulbs that are in the way around you will be thrown away. You, the nucleus, finally have the ability to be alone with the nucleus named girlfriend. Chance.

Of course, in the great business of picking up girls, it’s not enough to just get along alone. There is electrostatic repulsion between atomic nuclei. matter.

So, how to overcome the electrostatic repulsion, so that you and your girlfriend can truly blend in harmony, body and mind?

This requires two conditions, one is high temperature and the other is high pressure.

Now, everything is finally revealed. Although the sun’s core temperature is only 15 million degrees, it is the sun after all, and its core pressure is as high as 2.5 million atmospheres!

When the heat is not enough, the pressure can be combined, so the sun can easily achieve nuclear fusion. Earth scientists can’t create such a sky-defying pressure, so they have to increase the temperature as much as possible. When the pressure is not enough, the temperature can be combined. First release

So, nuclear fusion is actually trying to increase the pressure and temperature, forcing the nuclei to fuse with each other, just like when you went back to your hometown, your parents forced you to go on a blind date. First launch https://https://

Nuclear fusion does not have a fixed temperature or pressure, everything can be adjusted according to the situation, if you want the reactor to output high energy, increase the temperature and pressure, otherwise, decrease the temperature and pressure.

“Fifty million degrees!”

“The operation state of EAST has been reached!”

Everyone couldn’t help exclaiming, the full name of EAST is full superconducting tokamak nuclear fusion experimental device, located in the Hefei Institute of Physical Science, Chinese Academy of Sciences, before the double-helix stellarator fusion device of Xingchen Technology, EAST was the world’s largest nuclear fusion device. The most powerful tokamak-type fusion device.

The highest record of EATS is continuous operation for ten seconds at 100 million degrees Celsius, and 10.6 seconds for stable operation at 50 million degrees Celsius. This is the world record so far.

It is not difficult to see from this that fusion reactors operate at extremely high temperatures, and the difficulty will increase accordingly. EAST can run for a hundred seconds at 50 million degrees, and can only run for ten seconds at 100 million degrees.

The ambition of Xingchen Technology obviously does not stop at 50 million degrees, and the number on the screen is still climbing rapidly.

“Seventy million degrees!”

“Mr. Luo, what is the temperature setting for your experiment?” Someone finally couldn’t help asking.

Luo Jia turned his head, glanced at everyone’s faces, and then said lightly: “150 million degrees Celsius.”

Boom~

The feeling of sudden blood congestion in the brain made everyone dizzy. You must know that the super tokamak fusion device ITER, which has not yet been built, weighs 23,000 tons, and has concentrated the world’s top scientific research forces, Its limit operating temperature is only 150 million degrees Celsius, and the first fusion experiment of Xingchen Technology rushed to a record high! ?

French ITER and Huaxia CFETR have not yet been built. In the face of future fusion devices, the combined performance is not as good as the double-helix stellarator of Xingchen Technology. What kind of madness is this! ?

It should be known that both ITER and CFETR are super fusion reactors weighing tens of thousands of tons, while the double-helix stellarator is only a small test reactor, weighing only 142 tons.

It has to be said that the gap between different civilizations is too great. It is difficult for people on earth who are still in the stage of primary planetary civilization to imagine the development of the cosmic society.

“100 million degrees! It’s reached 100 million degrees Celsius!”

“The fusion device remains stable!”

“The temperature is still increasing rapidly, it’s unbelievable, what kind of magic did Star Technology use!?”

Everyone exclaimed in a low voice, inside the double-helix stellarator, under the unimaginably terrifying high temperature and pressure, the atomic nuclei are undergoing ferocious fusion reactions.

When the fusion device really climbed to the predetermined high temperature of 150 million degrees, the people at the scene became silent instead. They didn’t want to make a sound and destroy the sacred meaning of this night.

150 million degrees, this is a brand new record, the previous highest record was at 100 million degrees Celsius, running for ten seconds, this record was also created by Chinese scientific researchers.

However, with the addition of Xingchen Technology, the old records are completely dead. According to Luo Jia’s words, the reason why all records exist is to be broken!

One minute…

Three minutes…

Five minutes…

Ten minutes…

“Okay, let’s end.” Luo Jia said casually to Dr. Xie Tian in the communicator: “The first experiment does not need to run for too long, the important thing is to collect data.”

Until Dr. Xie Tian executed the order and the temperature of the reactor began to drop, everyone woke up like a dream.

This is not a question of the reactor running for ten minutes, nor is it a question of how many kebabs can be grilled at a temperature of 150 million degrees, but that Xingchen Technology has been able to retract and release freely, perfectly controlling every step of the fusion reaction. One step! It’s like walking in a garden!

Long live!

People could no longer bear the excitement in their hearts, embraced each other, shouted loudly, and shed hot tears.

This is an epic miracle. Human beings without controllable fusion are like children lying on the crib of the earth. Controllable fusion is the long-awaited pair of wings that will help human beings grow up , to the stars and the distance.

The unstoppable history is coming, the seventh year of Star Science and Technology, on March 5th, the test of the double helix stellarator was successful!

“The test was successful, Luo Jia’s fusion reactor test was successful!”

“It ran for a full ten minutes, and Luo Jia ended the operation on his own initiative. He said he was not in a hurry. It was the first time to mainly collect data, and we will do it after the fusion reactor durability test.”

“Can you imagine? When Luo Jia said that he was not in a hurry, the expressions of the leaders of the Chinese Academy of Sciences, they looked at Luo Jia as if they were looking at a monster! The eyeballs were so hanging that they didn’t fall to the ground!”

“Now all the experts are in a frenzy! They’re celebrating like crazy, drinking champagne glass after glass.”

“General, are you listening, General?”

Lu Junlin immediately called the general who was far away in the capital to report the good news of the success of the experiment, and the general stayed up all night, sitting on the sofa in the living room and waiting, looking at the wall clock.

“Well, I’m listening.” The general said after a moment of silence: “I’ve understood what you said, congratulate Luo Jia for me, and invite him to come over after finishing his business in Chengdu. I’m going to the capital, and I’d like to treat him to a drink.”

“Are you buying him a drink?” Lu Junlin was slightly taken aback.

“Is there something wrong?” The general said disapprovingly: “Tonight’s success is not only the success of Luo Jia and Xingchen Technology, but also the success of our entire Chinese nation!”

“The greatest glory of being a soldier is nothing more than being loyal to the country, wrapping the body in horse leather, resisting foreign enemies, and expanding the territory!”

“A hundred years of humiliation in modern times, every inch of land that has been lost is like a sharp knife, deeply inserted in the hearts of us soldiers. We only hate that the international order has been established, and we are unable to get back what we lost.”

“But Luo Jia made me see hope. He kept saying that the earth is too small. If human beings want to develop, they must go to the sea of ​​stars. Our China has already missed the first era of great navigation. , when the second era of great voyages begins, we, Huaxia, should take the lead!”

“For this ~Soverse.com~ Luo Jia told me a story.”

“A story?” Lu Junlin showed a puzzled expression on his face.

“Yes, Luo Jia told me a story written by Liu Cixin called Xiyang. Okay, the fleet circled the Cape of Good Hope and finally arrived in Europe, then pointed to London, bombarded Amsterdam, and established the Ming Dynasty across Eurasia.”

“In a blink of an eye, hundreds of years have passed, and China’s rule has spread to every corner of the world. Everyone is proud of speaking Chinese, learning Chinese etiquette, and being proud of marrying a Chinese. Opera, Chinese painting, calligraphy, and poetry are all swept away. Global.”

Lu Junlin was stunned. He had only read Liu Cixin’s books, just like 90% of people who claim to be science fiction fans have only read the Three-Body Problem. Lu Junlin didn’t read many science fiction works, let alone Liu Cixin. This guy actually wrote such flirtatious things, he has a lot of emotions in his bones, and he is also a nationalist.

However, thinking about it carefully, Lu Junlin couldn’t help his heart beat faster and his blood was racing. As a soldier, whenever he thought of the humiliation of the modern century, he couldn’t help but get red eyes.

*** once said that although Russia’s territory is vast, not an inch is superfluous.

This is not the case in China! ?

At this time, the general said excitedly: “Luo Jia said that he will open the road to the stars and the sea, and our soldiers will complete the expedition that we failed to complete hundreds of years ago in the second era of great navigation. ! For the Chinese nation, expand the territory!”
