Chapter 483 Tokamak Device
Yes!

During Qin Yuanqing's retreat period, time unknowingly turned over the special year of 2020, entered 2021, and came to January 2021, 1, December 8 of the lunar calendar!

It just so happens that this day is also the time when all departments of Mizuki, including scientific research institutions, are on the Spring Festival holiday. Whether it is researchers, lecturers, or professors, they all ushered in their own long Spring Festival holiday!
Qin Yuanqing, who was physically and mentally exhausted, became more determined to resign as the head of Mizuki. After all, scientific research alone consumed most of his energy, and he even wanted to split himself in half. Words are really a burden.

He basically pushes the specifics to Xu Jiayi and the other vice principals now, and they have handled it well, so there is no need for him to occupy the hole and not shit!
"Why do you want to resign as the head of Shuimu?" When Qin Yuanqing teased the two children and mentioned his plan to his wife, Jing Tian was completely puzzled.

The head of Mizuki, this is a very prominent position, whether it is in terms of rank or social influence, it is very prominent. I don't know how many people have struggled for the rest of their lives to become the head of Mizuki.

As a result, my husband disliked the identity of the head of Mizuki, and his position was a burden, and he wished to get rid of this burden.

What is this!
"After the Spring Festival, the main energy is still on scientific research. I really don't have time to deal with trivial matters. Moreover, Xu Jiayi has done a good job during this time. It's almost time to push her to the top!" Qin Yuanqing said: "The big change that hasn't happened in a century, The trend of history is rolling, if I don’t seize the opportunity, I will regret it for life! The mission of the times is hard to shirk!”

Qin Yuanqing can't tell his family about controllable nuclear fusion technology, anti-gravity technology, etc., because it's not a good thing for others to know about such a high-level confidential project.

Jing Tian was also very speechless, what was all this about, but she had never understood Qin Yuanqing.

WeChat Group's A-share listing is known as the largest listing financing in the history of the world, and the largest capital feast in history. The market value of WeChat Group broke through 1.3 trillion US dollars when it was listed, and the daily limit was directly raised on the day of listing.However, as the largest shareholder of WeChat Group, Qin Yuanqing did not appear on the stock exchange, and did not even send a message, as if he disappeared without a sound.

It seems that WeChat Group has nothing to do with Qin Yuanqing!

It is Jingtian, and Qin Yuanqing can only be seen at 12 o'clock every night.

She dared not say anything, dared not ask anything!
"How about we go back to our hometown for the New Year this year?" Qin Yuanqing looked at his wife.

"Maybe it's too hasty, and I have to attend a meeting on New Year's Eve." Jing Tian hesitated for a moment, shook his head and said.

Now she is also the head of a large group, and she is also very important in the industry. There are many meetings that need to be attended throughout the year. Some meetings can be attended by others, and some meetings have to be held in person.

And this meeting is one that cannot be shirked!

The time crisis, the entertainment industry and the hotel real estate industry are also in crisis, and many companies are struggling to support them. If this predicament can be reversed, it will be a theme of this meeting.

Even the Qingtian Group has suffered great difficulties. Dozens of film and television dramas that have been cast have been postponed for more than half a year or for a year. In addition, although the movie theater is relatively bleak, it has not opened for more than half a year, and everyone’s income has been greatly reduced. Watching movies There will be a little more consideration on the aspect, so that the box office for the whole year is less than one-third of the total box office in 2019.

Not to mention, the revenue of the hotel has also been greatly reduced, causing Qingtian Group to suffer huge losses. If Qingtian Group does not have bank loans on its books, it may face bankruptcy crisis.

Qin Yuanqing was a little disappointed, but he didn't force it. After all, people can't help themselves in the rivers and lakes. Since they choose this line of work, they will sacrifice a lot.

The entire Spring Festival was better than last year, but overall it was still a lot worse. The excitement of the previous Spring Festival has not yet been fully restored. Everyone also reduced visits to relatives and friends, minimized going out, and then became a melon-eating crowd with peace of mind. .

Qin Yuanqing also took advantage of the Spring Festival to cultivate his mind and character. He didn't start to go to work until the eighth day of the Lunar New Year, but the work was mainly concentrated on the heads of various departments. Seven will officially go to work.

However, Qin Yuanqing did not have such a good fate. On the tenth day of the new year, Qin Yuanqing participated in a joint meeting. The theme of the meeting was about controllable nuclear fusion technology. Qin Yuanqing submitted the project proposal of controllable nuclear fusion technology to his superiors. It's been a while.

This meeting involved almost all the heads of departments, as well as nuclear technology experts in the fields of nuclear fusion and nuclear power plants. As the world's first echelon in the field of nuclear technology, Huaxia has already established a complete team in nuclear technology , and even the fourth-generation nuclear power plants are at the leading level in the world.

"Everyone, you must have read the "Project Proposal on Controllable Nuclear Fusion Technology" written by Academician Qin himself. This meeting is to discuss whether the project proposal is feasible, reasonable, and advanced." The host of the meeting said in a deep voice.

A nuclear expert coughed, drawing attention, before saying, "The promise of controlled nuclear fusion is undeniably promising, and that's what I would answer to anyone who would ask me that question. But know that , The ITER project is not optimistic so far. The annual budget is exceeding the standard by 7 million U.S. dollars, but the results are not satisfactory. The governments of various countries, including the United States, have gradually lost patience. X freed up funds and has shut down the WEGA experimental group."

"Controllable nuclear fusion is a systematic project. Whether it is inertial confinement or magnetic confinement, or tokamak and stellarator, it is only after a series of questions are answered that it is possible to finally solve this problem. But now, None of the problems we are facing has been fundamentally resolved." The expert said slowly.

The faces of the others changed, and then they looked at Qin Yuanqing at the front, because this expert, although only 50 years old, is a well-known nuclear technology expert in China. He participated in the capture and construction of the fourth-generation nuclear power plant technology. The list of the latest achievements in nuclear fusion also has his name.

In terms of the right to speak about controllable nuclear fusion, he can be ranked in the top ten in the country!

Qin Yuanqing looked at the expert with great interest, and then asked with a smile: "Professor Ma, what problems do you think need to be solved?"

This nuclear technology expert was very popular when he was elected as an academician, but unfortunately he lost the election by three votes, but it cannot be denied that he belongs to Huaxia Nuclear Physics and has a lot of say in controllable nuclear fusion.

Professor Ma thought for a while, and then said: "Only in terms of engineering, we need a larger electromagnetic field to complete the magnetic confinement of the plasma. However, this is not easy to solve. A large magnetic field means a large current, and When the current passes through the conductor, heat will be released. We must soak the wire with liquid helium, on the one hand to reach the superconducting temperature, and on the other hand to prevent the heating effect of the current from causing the wire to heat up."

"Just having a magnetic field is not enough, we have to find a way to control the magnetic field... Regardless of whether it is the current stellarator device or the tokamak device, there are obvious advantages and disadvantages. At present, there is no device that can Control the magnetic field." Professor Ma said: "Of course, after talking about so many problems, in the final analysis, we still have to return to the material."

"If there is a material that can achieve superconductivity at room temperature, or at least under less extreme conditions, we can create a larger artificial electromagnetic field to confine the plasma, and many problems will become fundamental. Not a problem." Professor Ma shook his head when he said this, obviously not optimistic about it.

"The tokamak device and the stellarator device don't work, so we need to develop a new device to realize it. Why should we be limited in our thinking, but we have to fight to the end with these two devices!?" Qin Yuan smiled lightly.

Both the tokamak device and the stellarator device are containers that use magnetic confinement to achieve controlled nuclear fusion in the current international research on controlled nuclear fusion.

The tokamak device is a ring-shaped container that uses magnetic confinement to achieve controlled magnetic confinement to achieve controlled nuclear fusion.It was originally invented by Azimovich et al. at the Kurchatov Institute in the 20s.The center of the Tokamak is a ring-shaped vacuum chamber with coils wound around it. When the Tokamak is powered on, a huge spiral magnetic field will be generated inside the Tokamak, which will heat the plasma to a very high temperature to achieve nuclear fusion. the goal of.

It is precisely because of the development of the Katomak device that Azimovich announced the realization of the T-1968 Tokamak at the Third International Conference on Plasma Physics and Controlled Nuclear Fusion Research held in Novosibirsk in 3. The electron temperature is 1 keV, the proton temperature is 0.5 keV, and nτ=10 to the 18th power m-3.s. This is a major breakthrough in the research of controlled nuclear fusion, and thus set off a tokamak boom in the world. A number of large-scale tokamak devices have been built or rebuilt successively in various countries.

For example, ST Tokamak, a large-scale rebuilt stellarator-C in Preston, USA, Almak of Oak Ridge National Laboratory; TFR Tokamak of France's Vonkenai-O-Rods Institute; Cleo ( Cleo); Pulsator Tokamak of the Max Planck Institute in Germany.

It is Huaxia. On September 2006, 9, the new generation of thermonuclear fusion device EAST, which took 28 years and cost 8 million yuan to independently design and build, successfully completed the discharge test for the first time, obtaining a current of 2 kA and a time close to The core of the 200-second high-temperature plasma discharge actually belongs to the tokamak device.

It can be said that the tokamak device has made great contributions to the international research on controllable nuclear fusion. Many scientists believe that the tokamak device is the key for people to master controllable nuclear fusion and the key to open a new world.
