After the celebration banquet, Xu Chuan finally took off his white coat and left the base of Qixia Mountain.

He handed over the overhaul and maintenance of the Daybreak fusion equipment to Peng Hongxi and Zhao Hongzhi, the team leader who went to the Planck Plasma Research Institute for training.

The former is in charge of the overall situation, while the latter is more familiar with the original ASDEX device, after all, he has been training for so long on the Germanic side.

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

At present, the longest operating time of tokama devices or tokamak-like devices in the world is more than 120 seconds created by the superconducting tokamak device in France, and controlled heat release is achieved to generate energy.

However, the sophistication and performance of a controlled fusion reactor is not just about the length of operation.

If you look at the running time alone, back in 2012, the EAST unit achieved a 20 million degrees Celsius high-parameter deflector plasma operation for up to 403 seconds.

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

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

However, at present, no country has been able to achieve a net energy gain of fusion reaction on the 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 running time to the pursuit of hundreds of millions of temperatures while pursuing running time.

For example, Korea has set a running time of 100 million temperatures and 20 seconds this year, breaking the world record of 100 million temperatures.

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

In other words, if he wants to break the record in one fell swoop, the duration of the 100 million temperature must be at least 100 seconds or more to be able to sit at the same time as the ESAT.

But for him, a 100-second runtime is not the goal.

The first run of the Daybreak Fusion Device, his goal is in thirty minutes!

If this goal is placed in the field of controlled nuclear fusion, others will definitely think that he is crazy.

Not to mention the tokamak device, it is a stellarite simulator with unique advantages in the control system, and the longest running time is only more than six minutes.

Half an hour, it's a fantasy.

But setting this goal, Xu Chuan is still a little sure.

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

The first is the numerical control model of plasma turbulence, although the previous acceptance run only lasted for a short time, but from the feedback data, this mathematical model he built up single-handedly is more perfect than he imagined.

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

Moreover, compared with the 25T magnetic field that EAST can provide, it can provide more than 40T confined magnetic field dawn, which is obviously more advantageous.

So after half an hour of operation, Xu Chuan is still sure to do it.

On the second day of the successful ignition of the dawn fusion device, the media invited to participate in the acceptance experiment such as "Nuclear Industry News" and "Science and Technology Innovation Herald" reported 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 go around the Qixia Nuclear Fusion Industrial Park and made some concerned inquiries and cares to show their attention to the Qixia Controlled Nuclear Fusion Project.

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

Because this will be his return to NTU.

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

However, on the side of Nanda, there is a person who has a good relationship with him from the United States side.

With a hint of cheerfulness, Xu Chuan rushed back to NTU.

Pushing open the door of the office, he also had a smile on his face when he saw the familiar figure.

"Long time no see, senior sister!"

Rushed back from the United States, it was Liu Jiaxin, who rushed to Princeton to study in 18 years, and today, more than two years have passed.

In the past two years, although the contact has never been broken, Xu Chuan has only met her at the beginning of 19, and the following time, on the one hand, because the air ticket is too expensive, this senior sister rarely comes back, and on the other hand, he is too busy after returning to China, and he misses it every time the senior sister comes back.

"Long time no see." Seeing Xu Chuan, Liu Jiaxin's face bloomed with a smile of joy, and she whispered hello as before.

"Congratulations on graduation!" Xu Chuan stepped forward with a smile and congratulated.

From September '18 to now, it's only two years, and two years to finish school from Princeton, which is quite good.

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

The first is to participate in the 'automatic cloud detection algorithm' jointly developed by Princeton and the Spanish company Ubotica, and has made a lot of contributions to the algorithm.

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

After the processing of the automatic cloud detection algorithm, a large number of blurry and useless images containing clouds in the satellite photos have been identified and deleted, and only the usable photos are transmitted back to the ground, saving 30% of the bandwidth and significantly reducing the transmission cost.

The second is even more heavyweight, when she was studying at Princeton, where she reimagined Princeton's AI-powered cybersecurity platform with the School of Information to detect sophisticated cyberattacks faster, more accurately, and more thoroughly.

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

This is definitely a huge breakthrough for the development of cybersecurity. And this senior sister is one of the core main forces of this refactoring platform.

I have to say that after solving the difficulties in life and stepping into a higher-level learning platform, Xu Chuan was amazed by her outstanding talent.

After a few words of greeting, Xu Chuan asked with a smile, "I shouldn't go out again when I come back this time, right?" ”

Liu Jiaxin nodded and said softly, "Well, don't go out." ”

"Have you figured out where to work?" Xu Chuan smiled and asked: "With your current ability, I'm afraid you won't refuse to submit a resume to any company that develops artificial intelligence, right?" ”

"I haven't been in contact with it in China for the time being." Liu Jiaxin shook her head and said.

After she completed the reconstruction of Princeton's artificial intelligence network security platform before graduation, famous companies such as Google and Apple sent her offers, and the highest annual salary of the offer even reached 1.6 million meters.

Although this 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 been in contact with a domestic company, why don't you come to work with me?" ”

"As you should know, I opened a materials research institute and made a computational model for materials research. As the institute grows, work on cybersecurity is a big problem. ”

"Since the announcement of high-temperature copper-carbon-silver superconducting materials at the end of last year, the institute has encountered many cyber attacks, coupled with future scientific research and development, I am ready to make a protective platform first."

"In addition, including the future development of artificial intelligence and big data, I also need a reliable person to do the management."

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

He thought about this after he was disrupted by representatives of the AMSC superconducting company at a press conference on high-temperature copper-carbon-silver superconducting materials last year.

There is no doubt that the protective platform is indispensable.

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.

In these two aspects of development, he is ready to set up a new company to carry out a certain degree of layout, not necessarily to seek how much market or how big it is, but at least to ensure that he is qualified to enter the industry and ensure his own development.

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

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

Xu Chuan also knew, but there was nothing he could do at the moment.

It is impossible for him to give up on the project he is currently working on to optimize the material calculation model, so he can only put it down for the time being.

At the beginning of the year, he was going to find a suitable person to support this work through headhunting, but the things on the controllable nuclear fusion project have been busy and have been stranded.

Now that this senior sister is back, with her current ability, there shouldn't be a big problem in supporting this work.

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

The speed of the promise was so crisp that Xu Chuan didn't react for a while.

After a pause, he said with a smile: "You didn't talk about the salary or anything, and you agreed?" ”

"I'm not afraid that I'll sign a contract for you to pay to work."

PS: There is one more chapter in the evening, ask for a monthly pass!
