Great Country Academician

After the celebration banquet, Xu Chuan finally took off his white coat and left Qixiashan Base.

He entrusted Peng Hongxi and Zhao Hongzhi, the team leader who went to the Planck Institute of Plasma Research for training, to overhaul and maintain the Lexiao fusion equipment.

The former is responsible for controlling the overall situation, while the latter is more familiar with the original ASDEX device, after all, it has been trained in Germany for such a long time.

After the acceptance work is completed, the next step, as Xu Chuan said at the celebration banquet, is to officially start the ignition and operation experiment of the Lixiao fusion equipment.

At present, the longest operating time of Tokama device or Tokamak-like device in the world is more than 120 seconds created by the superconducting Tokamak device in France, and it realizes controlled heat release to generate energy.

However, the advancement and performance of a controllable nuclear fusion reactor is not just based on the length of operation.

If you just look at the running time, as early as 2012, the EAST device achieved a high-parameter divertor plasma operation at 20 million degrees Celsius for 403 seconds.

But this is only a small step forward on the road to controllable nuclear fusion.

Because in addition to the long running time, there are two key indicators: plasma temperature and plasma density. Of course, the most important thing is the energy gain coefficient.

However, at present, no country has achieved the net energy gain of fusion reaction in terms of energy gain coefficient (Q).

Therefore, this indicator is basically excluded from the fusion performance at present, and the latter will only be considered when the first three conditions are met at the same time.

At present, countries have adjusted from the simple pursuit of operating time to the pursuit of operating time while pursuing billion-level temperatures.

For example, the country of Korea created a 100 million temperature run time of 20 seconds this year, breaking the world record at a temperature of 100 million.

However, this record will soon be exceeded. Xu Chuan remembers that next year, in May 21, the EAST device in Luyang achieved repeatable plasma operation at 120 million degrees Celsius for 101 seconds and 160 million degrees Celsius for 20 seconds. , extending the original record of 20 seconds at 100 million degrees Celsius by a full five times.

In other words, if he wants to break the record in one fell swoop, the duration of the billion-level temperature must be at least 100 seconds, so that he can sit with ESAT at the same time.

But for him, a runtime of 100 seconds was not the goal.

The first run of the Dawn fusion device, his goal was in thirty minutes!

If this goal is placed in the field of controllable nuclear fusion, others will definitely think that he has lost his mind and is crazy.

Not to mention the tokamak device, it is the stellarator with unique advantages in the control system. The longest running time at present is only more than six minutes.

For half an hour, this is simply a fantasy.

But Xu Chuan is still somewhat sure of setting this goal.

Compared with other controllable nuclear fusion devices in the world, it has two obvious advantages!

The first one is the numerical control model of plasma turbulence. Although the previous acceptance run lasted only a short time, judging from the feedback data, this mathematical model he built by himself is more perfect than he imagined.

The second advantage is the modified and optimized Daybreak device, which is now a full superconducting confinement fusion device just like EAST.

Moreover, compared with the 25T level magnetic field that EAST can provide, the advantage of being able to provide more than 40T confinement magnetic field is obviously greater.

So Xu Chuan is still sure to do it for half an hour.

On the second day after the successful ignition of the Lixiao fusion device, "Nuclear Industry News", "Science and Technology Innovation Herald" and other media invited to participate in the acceptance test made a phased report on the research progress of Qixia's controllable nuclear fusion project .

After receiving the news, the leaders of Jinling City also organized a delegation to visit the Qixia Nuclear Fusion Industrial Park and made some inquiries and care to express their importance to the Qixia Controllable Nuclear Fusion Project.

However, Xu Chuan, whom the city leaders most wanted to see, did not see him in this operation.

Because of this meeting, he has already returned to Nantah University.

It is not that there is any important scientific research work that needs to be carried out at Nantah University. The overhaul and maintenance of the Lixiao fusion device has just begun, and the experimental data generated by the acceptance operation has not yet come out.

But on Nantah's side, there is a person who has a good relationship with him who came back from the United States.

With a tinge of joy, Xu Chuan hurried back to Nantah University.

Pushing open the door of the office and seeing that familiar figure, he also had a smile on his face.

"Long time no see, senior sister!"

The one who came back from the United States was precisely Liu Jiaxin, who rushed to study in Princeton in 2018. Today, more than two full years have passed.

In the past two years, although the contact has never been broken, Xu Chuan only met her once at the beginning of 2019. In the following time, on the one hand, because the air ticket was too expensive, this senior seldom came back. On the other hand, he was too busy after returning to China, and missed every time the senior sister came back.

"Long time no see." Seeing Xu Chuan, Liu Jiaxin had a joyful smile on his face, and greeted him softly as before.

"Congratulations on graduating!" Xu Chuan walked forward with a smile and congratulated.

From September 2018 to the present, it has only been two years. It took two years to complete my studies from Princeton, which is already quite excellent.

And during the two years of study, this senior also participated in two large-scale projects that could be world-class.

The first one is to participate in the "Automatic Cloud Detection Algorithm" jointly developed by Princeton and the Spanish company Ubotica, and has made considerable contributions to the algorithm.

The main purpose of this technology is to use artificial intelligence technology to solve the problem that the photos taken by artificial satellites are often covered by clouds.

After being processed by the automatic cloud detection algorithm, a large number of fuzzy and useless images containing clouds in the photos taken by satellites have been identified and deleted, and only usable photos are sent back to the ground, saving 30% of bandwidth and significantly reducing transmission costs.

The second one is even more important. When she was studying in Princeton, she joined the Institute of Information Technology to reconstruct Princeton's artificial intelligence network security platform, which can detect complex network attacks faster, more accurately and more thoroughly.

The optimized platform can quickly detect anomalies, assist in identifying attack patterns, and identify unknown threats based on a large amount of multi-source heterogeneous data and algorithms, shortening the time required to detect advanced persistent threats (APTs) from an average of three months to Days.

This is definitely a huge breakthrough for the development of network security. And this senior sister is one of the core forces of this reconstruction of the platform.

It has to be said that Xu Chuan was amazed by her burst of talent after solving the difficulties in life and stepping into a higher level of learning platform.

After exchanging a few words of pleasantries, Xu Chuan asked with a smile, "I'm sure you won't go out again this time, right?"

Liu Jiaxin nodded, and said softly, "Well, I won't go out."

"Then have you decided where to work?" Xu Chuan asked with a smile: "With your current ability, I'm afraid you won't refuse to submit your resume to any company that develops artificial intelligence, right?"

"I haven't contacted them in China yet." Liu Jiaxin shook her head and said.

After she completed the reconstruction of the artificial intelligence network security platform at Princeton before graduation, well-known companies such as Google and Apple have sent her offers, and the highest offer even offered an annual salary of 1.6 million yuan.

Although the annual salary is indeed considerable, she still wants to come back and contribute to the development of the country more than working abroad.

Xu Chuan smiled and said, "If you haven't contacted domestic companies, why don't you come and work with me?"

"You should know that I opened a materials research institute before and made a calculation model for the direction of materials research. With the development of the research institute, work on network security is a big problem."

"Since the high-temperature copper-carbon-silver superconducting material was announced at the end of last year, the institute has encountered many cyber attacks. Coupled with future research and development, I plan to build a protection platform first."

"In addition, including the development of artificial intelligence and big data in the future, I also need a reliable manpower for management."

Establishing his own protection platform for the Chuanhai Materials Research Institute, as well as developing things in the fields of artificial intelligence and big data, is not a sudden decision he made now.

After he was disrupted by a representative of AMSC Superconducting Company in the United States at a press conference on high-temperature copper-carbon-silver superconducting materials last year, he thought about this.

A protective platform is indispensable, there is no doubt about it.

And artificial intelligence and big data, this is the future development trend.

Whether it is daily life or scientific research, it is impossible to bypass artificial intelligence and big data.

For the development of these two aspects, he plans to set up a new company to carry out a certain degree of layout. He does not necessarily want to seek a large market or grow in it, but at least to ensure that he is qualified to enter this industry and guarantee his own development.

For example, the material calculation model of the Chuanhai Materials Research Institute, the underlying architecture was written by him before, but he doesn't know much about the program, and the current architecture has limited subsequent development.

Academician Zhang Pingxiang clearly pointed out this problem when studying and optimizing high-temperature copper-carbon-silver composite superconducting materials.

Xu Chuan also knew, but he had nothing to do at the moment.

It is impossible for him to give up the current project and optimize the material calculation model, so he can only put it down temporarily.

At the beginning of the year, he planned to find a suitable person through headhunting to support this job, but he was always busy with the controllable nuclear fusion project and ran aground.

Now that the senior is back, with her current ability, it shouldn't be a big problem to support this job.

After listening to Xu Chuan's words, Liu Jiaxin agreed almost without thinking: "As long as you don't dislike me."

The speed of agreeing was so straightforward that Xu Chuan didn't react for a while.

After a pause, he smiled and said, "You didn't talk about salary or treatment, so you agreed?"

"I'm not afraid that I will sign a contract and let you pay to work."

PS: There is another chapter tonight, ask for a monthly pass!
