Technological power starts with upgrading lenses

Jiangbei Province, ZZ City.

As the temperature gets colder, the belated first snow finally floats in the air.

Before we knew it, a month and a half had passed since the renovation and upgrade of the EAST device.

However, the progress of the engineers so far is still limited to the disassembly of the equipment. After all, every action of this sophisticated large-scale equipment requires professional analysis and evaluation, and there cannot be any errors in the sequence. Parts also need to be numbered and specially stored according to regulations.

The progress cannot be made any faster even if we want to.

Not to mention that Zhong Weijian and the others also received instructions from Kang Chi to delay the upgrade progress as much as possible.

You can't really enter the parts replacement process for at least three months.

Although Zhong Weijian chose to support Kang Chi at the beginning, this person will inevitably become anxious after being idle for a long time, especially since Kang Chi took charge of China's controllable nuclear fusion general project, he has never held a normal technical seminar.

Everyone is like a sheep being herded. Except for the engineer responsible for dismantling and assembling the equipment, everyone else is basically idle.

It’s as if Kang Chi’s appointment is to postpone the research on controllable nuclear fusion...

Zhong Weijian put the journal in his hand on the table, looked up at the snowflakes floating outside the window, and couldn't help but light another cigarette.

"Old Zhong, Professor Cheng is looking for you!" His wife's voice suddenly came from outside the study.

Zhong Weijian stood up quickly, walked to the living room and greeted Cheng Tao with a smile: "I was just thinking about going to your house for dinner, but I didn't expect you to move faster."

"Do you still want to eat?" Cheng Tao shook his head helplessly, "Do you know what just happened?"

Seeing Cheng Tao's serious expression, Zhong Weijian couldn't help but asked nervously: "What happened?"

"This morning, Kang Chi gave an open class to students at Suzhou University."

"Public class?"

"Yes, and it's about controllable nuclear fusion... an open science course."

"What's the problem?"

Zhong Weijian became more and more confused after hearing this.

Isn't it normal for Kang Chi to go to Jiangsu University to give a public class?

What's all the fuss about?

To put it bluntly, he is so idle that he would rather go to the university to give lectures to students than arrange jobs for them...

But there's actually nothing wrong with that.

Anyway, the time of a class will not waste much time, and this will not have a big impact on the huge workload of planning large-scale scientific research directions.

"It's not a problem, it's just his point of view...how to put it, I can't describe it."

As he spoke, Cheng Tao took out his cell phone, did a casual search on the Internet and handed it to Zhong Weijian.

"You'd better see for yourself."

Zhong Weijian took the phone and sat on the sofa, then clicked to start playing.

The content of the video is this open class.

The reason why open classes are called open classes is that students and teachers from Suzhou University can attend them. Suzhou University even conducted a high-profile online live broadcast...

It is well-known as promoting the enthusiasm of all people to learn.

But the brothers and colleges all smelled the strong sense of showing off...

Ordinary classrooms obviously couldn't satisfy the enthusiastic SU students, so the lecture venue was changed to the school's auditorium. Even though the venue was so big, it was basically full.

Since it was an open class in front of the general public, Kang Chi did not intend to talk about anything too professional. After saying hello, he talked about controllable nuclear fusion based on the opinions of students collected by Suzhou University in advance.

This is also an issue that everyone is more concerned about after Kang Chi became the chief engineer of controllable nuclear fusion.

As soon as Zhong Weijian finished reading the beginning, Cheng Tao reminded: "What he said before was all about the importance of controllable nuclear fusion and the current international mainstream research directions. You can fast forward directly to 35 minutes..."

So Zhong Weijian directly dragged the progress bar and started looking at 35 minutes.

"...Take magnetic confinement devices such as tokamak and stellarator as examples. Suppose we have a breakthrough in material technology and have N120 magnetic pole materials and high-temperature carbon-based superconducting materials with k thermal conductivity, as well as other major materials. If the performance reaches the level of this table, then the entire device is upgraded and optimized, using deuterium-tritium as fuel, and assuming a perfect control system, its simulation result in a supercomputer will be-"

Kang Chi released a calculated data:

[Tokamak: magnetic field strength 89.9T, Q value 2.6, first wall damage rate 0%...]

[Stellarator: magnetic field strength 64.3T, Q value 3.2, first wall damage rate 0.0012%...]

After seeing this string of data, Zhong Weijian's pupils shrank immediately, and then he looked up at Cheng Tao: "Do you think this premise... is possible?"

Cheng Tao shook his head: "I'm not sure... If someone else says this, I think it's 100% just a purely technical assumption. But if it's Academician Kang... I personally think it's still possible, or maybe He has great confidence that he can achieve it.”

Cheng Tao's words made Zhong Weijian's hand holding the phone tremble slightly.

Kang Chi didn't even listen to a word of what he said next.

If the premise that Kang Chi just mentioned can really be achieved, then there is no need to consider the constraint time at all, and the device can run as long as it wants.

The constraint strength of 89.9T is enough to lock the nuclear fusion reaction firmly where it should stay.

The simulated damage rate of 0% on the first wall also proves this with data.

The magnetic confinement performance is even a bit excessive.

However, considering that the magnetic field of the stellarator equipment is relatively complex, the magnetic field intensity is reduced, resulting in a damage rate of 0.0012% on the first wall.

The data of Tokamak 89.9T may be the best parameters after optimization.

But no matter what, if this premise can really be realized, the technology of controllable nuclear fusion can definitely be mounted on the rocket and complete a technological leap forward!

After Zhong Weijian calmed down, he dragged the video back to 35 minutes with some complicated emotions, watched it carefully again, and then continued to read.

"Although the Q value of the stellarator can reach 3.2 at this time, it is still unable to meet the commercialization of controllable nuclear fusion. It is like a gas-hungry engine that consumes a lot of fuel but can only output The power is extremely small, and the cost-effectiveness of manufacturing and operating it may take hundreds or even thousands of years to recover the cost.”

A student below immediately raised his hand. After getting Kang Chi's permission, he stood up and asked, "Why don't you just assume the Q value is 5 and work backwards to calculate the device material requirements?"

"Well... this is a good question. I have also conducted such simulations, but the calculation failed. It may be that my mathematical model is not good enough, or it may be that this parameter has far exceeded the scope of the model. In fact, I These material parameters assumed now are already a very difficult standard for us humans to meet..."

When he saw this, Zhong Weijian understood immediately.

Kangchi is not optimistic about the magnetic constraint route!

The tokamak and stellarator included in this route are currently the main research directions of controllable nuclear fusion...
