Chapter 743: From the Max Planck Institute for Plasma Physics in Germany

In early April, the atmosphere of early spring was stronger, and the busyness of the research institute reached its peak since its establishment.

There were no heroic words.

Just on Monday, Xu Qingzhou held a routine meeting for everyone as usual and threw himself into busy work.

The process of integrated installation was quite cumbersome.

The most core vacuum chamber integration required precise alignment of the negative triangular plasma configuration with the toroidal vacuum chamber to ensure that the error of the distance between the plasma boundary layer and the first wall was ≤1mm.

The Materials Ding Liyan opened full-load mode, and days passed by.

The news Xu Qingzhou expected from the Southwest Institute of Nuclear Physics did not come, but he waited for the news from the Max Planck Society first.

The Max Planck Institute for Plasma Physics in Germany announced.

Just on April 1, the W7-X stellarator passed the experiment to maintain the peak of the triple product for 70 seconds, officially completing the leap of the stellarator triple product peak from the second level to the minute level.

This news can be considered to have set off a stormy sea in the field of controllable nuclear fusion.

It means that in just half a year, the energy confinement capability of the W7-X stellarator has increased by more than 60%.

Previously, there had always been a technical dispute between tokamaks and stellarators.

But due to high construction costs, greater technology, etc., the world mainstream still chose the former, and even international cooperation controllable nuclear fusion used tokamaks.

But now the stellarator has created records again and again, further verifying the engineering feasibility of the stellarator technical route.

It can be foreseen that a large amount of funds will definitely flow into the field of stellarator development in the next period of time.

Klinger even specially sent an email to Xu Qingzhou, providing some parameters for the operation of superconducting magnets, to express his gratitude for the superconducting magnets provided by Xu Qingzhou and the others.

Xu Qingzhou accepted it calmly. A large part of the reason why the stellarator can operate for long pulses is due to the substrate-free Nb3Sn thin film. He roughly looked at the data of the W7-X stellarator and turned his attention back to the work at hand.

Rongcheng.

"The tea is on the table, brew it yourself." In the office, Academician Liu Fanyang lowered his head and looked at the materials in his hand, saying to the fat old man who came in.

The fat old man was not polite either, brewing tea on his own, "The weather in your Rongcheng, it's only this season and autumn that people can live."

The fat old man is called Wang Pingbai, an expert in nuclear physics invited by Liu Fanyang from the United States.

Complaining, Wang Pingbai asked again: "Looking at the data from Germany?"

"Hmm, just finished reading."

Liu Fanyang closed the materials in his hand and sighed with Wang Pingbai: "Minute level... Old Wang, I have a premonition that controllable nuclear fusion commercialization is getting closer and closer to us."

"Yes, currently W7-X needs to coordinate the millisecond-level precision of particle injection and microwave heating for every second of confinement time added. Maintaining 70 seconds represents a generational leap in the control system, and can even shorten the design cycle by 90%. This is a very terrible data."

Wang Pingbai said in a deep voice: "It cannot be denied that in stellarator technology, the Max Planck Society is still the only one."

"The gap exists. Even if we have obtained plasma confinement optimization and diagnostic and heating technology, we still cannot keep up in a short time. But we have successfully verified the quasi-helical symmetric magnetic field configuration in CFQS-T, and we will have our own first prototype in two years, which can be considered as taking the first step."

Liu Fanyang's mentality was quite good.

Plasma confinement optimization and diagnostic and heating technology belong to one of the core technologies of W7-X, involving plasma time and magnetic field strengthening. Although their technical route is different from W7-X, the essence of plasma confinement time and magnetic field control is the same.

Once the stellarator design is completed, it will achieve the world's first ultra-high-precision "quasi-toroidal symmetric magnetic field configuration," reducing neoclassical transport losses and improving plasma confinement performance.

It will definitely be able to take a place in the stellarator field.

The results of the first stage are very gratifying, but the subsequent work is still difficult.

The biggest obstacle is still talent.

In the past year, many scientists have been attracted by high wages, but in terms of talent reserves in the stellarator field, they still cannot compare with giants like the Max Planck Institute for Plasma Physics. ===== CHAPTER 744 =====
