Secondly, when high-energy ions escape from the confinement zone and encounter the first wall, impurities will be introduced into the plasma, reducing the heating efficiency of high-energy ions, directly affecting the plasma performance in future fusion reactors, and becoming a stumbling block to steady-state long pulse operation.

This is a problem that has existed since tokamak was proposed.

The reason why stellarators are now beginning to be viewed favorably by various countries again is that, on the one hand, the development of superconducting materials has solved the problem of unstable magnetic control of stellarators. This is because it does not have the magnetic surface tearing of tokamak, and the plasma

Problems such as magnetic islanding are more suitable for control.

But if problems such as magnetic surface tearing and plasma magnetic islands can be solved, there is no doubt that tokamak is more suitable for achieving controllable nuclear fusion than stellarators.

Because it has huge advantages in increasing the plasma temperature.

But, can it be done?

This chapter is not over yet, please click on the next page to continue reading! To be honest, Peng Hongxi doesn’t know about this issue.

But on today's blackboard, he saw a glimmer of hope.

Although now he is standing in front of the blackboard, listening to the explanation and looking at the calculations, he can't keep up with the rhythm. He can only roughly understand his ideas from some words.

But scientific development is sometimes like this, especially in mathematics, whether an idea is feasible or not, sometimes the first intuition is quite accurate.

". From these data, by changing the central projection angle parameter Λ0 in the high-energy ion distribution function to change the high-energy ion species and their share size loaded into the simulation system, it can explain the resonance of high-energy ions with the 2/1 tearing mode

It is feasible that the interaction excites the dominant resonance relationship of the 2/1-like fishbone model."

"As for the specific situation, I'm afraid we need to wait until the Dawn Device implements the deuterium-tritium fusion experiment and collects enough data to confirm."

In front of the blackboard, Xu Chuan threw the chalk in his hand back into the chalk box and turned to look at Peng Hongxi.

The old man did not answer immediately. He thought for a while and then said with shining eyes: "From your analysis and data, the tearing mode can couple with the Alfvén mode driven by high-energy ions to produce new physical phenomena, and the large-scale

Amplitude Alfvén perturbations can nonlinearly drive tearing mode reconnection and excite macroscopic magnetic islands."

"So, how to stabilize the Alfvén disturbance should be your main idea, right?"

Hearing this, Xu Chuan grinned, nodded and praised: "Yes, Mr. Peng is still awesome! He can see through the core idea at a glance."

"If the occurrence of Alfvén disturbance can be suppressed to a certain extent, theoretically, the phenomenon of magnetic surface tearing will be reduced a lot. This may be a way to solve the problem of magnetic surface tearing."

Hearing Xu Chuan's praise, Peng Hongxi shook his head and said: "What a great thing! I'm old, really old. With your detailed explanation, it would take me a long time to figure it out."

"But judging from what you said, this may indeed be feasible."

After a pause, he continued: "I am looking forward to it even more now. With you here, maybe I can really see the spark of controllable nuclear fusion light up in my lifetime."

ps: I’m stuck today, so let’s start with this chapter.

In addition, I would like to ask if you are interested in this detailed solution to the principle and process of controllable nuclear fusion?
