Chapter 301 The Manuscript Was Stolen? ? ?

The leaders of Jinling City left, and took Gao Hongming with them to discuss the settlement of controlled nuclear fusion.

In the huge villa, only Xu Chuan and Peng Hongxi were left.

"I didn't expect you to solve the nuclear waste problem so quickly." Peng Hongxi sighed after taking a sip of tea.

When the young man in front of him invited him to join the project last year, he never thought that such a large project could be completed in a year.

Xu Chuan smiled and said, "It's just luck. I chose the right direction, so the research will naturally be faster."

Peng Hongxi shook his head slightly and said, "How can there be luck without strength? I have seen your solution to the energy level and stability of the linear particle accelerator. If you don't have a deep understanding of physics, you can't come up with such a solution."

After a pause, he continued, "Let's not talk about this, let's talk about controlled nuclear fusion."

"I heard that this controlled nuclear fusion project is independent and you are responsible for it. So have you considered the route of controlled nuclear fusion? Which one are you going to take, magnetic confinement? Or inertial confinement?"

Magnetic confinement and inertial confinement are the two mainstream international routes for studying controlled nuclear fusion. Among these two routes, the United States is more optimistic about inertial confinement and has gone relatively far on it. China has placed its bets on the magnetic confinement route and has gone further on it.

Xu Chuan thought for a while and said, "Compared with inertial confinement, I am more optimistic about magnetic confinement."

"Why?" Peng Hongxi asked with interest.

Xu Chuan pondered for a moment and said, "Inertial confinement does not use magnetic fields to control fusion plasma, but uses shock waves to compress it to the huge density required for fusion. The plasma only maintains its shape for a moment through inertia, and then expands and releases energy."

"Compared with magnetic confinement, inertial confinement has a fatal disadvantage. The current laser energy enhancement is destined to its laser can only be fired once every few hours, and it cannot produce continuous and stable energy. It is difficult to commercialize it, and the actual output energy is far lower than the input energy."

"And how to increase the central pressure in the fuel hot spot to billions of times the atmospheric pressure is one of the keys to achieving commercially viable nuclear fusion."

"If these two points are not solved, it can be said that it is a long way to achieve commercial power generation in inertial confinement. In comparison, even magnetic confinement has some problems, but I am more optimistic about it."

"Then are you going to study tokamaks or stellarators?" Peng Hongxi asked.

Xu Chuan shook his head and said, "Neither."

"Huh?" Peng Hongxi cast a puzzled look at the young man sitting opposite him.

Xu Chuan leaned back on the sofa with a relaxed smile on his face: "Both tokamaks and stellarators have their own shortcomings."

"Tokamaks are currently the more mainstream magnetic confinement method, with advantages such as very little waste generated by reactions and good reproducibility, but there are still technical difficulties, such as how to stably confine plasma."

"Although stellarators have inherent advantages in energy confinement and their confinement of plasma far exceeds that of tokamaks, the confinement performance of stellarators is far lower than that of tokamaks, and it is currently unable to achieve precise quasi-symmetry. This means that any slight violation of symmetry may lead to a significant enhancement of neoclassical transmission."

Peng Hongxi asked curiously: "What is your choice?"

Xu Chuan smiled and said: "Multiple magnetic mirrors, tight ring control."

"Multiple magnetic mirrors, tight ring control?" Peng Hongxi repeated with some confusion in his eyes. He has been engaged in nuclear fusion for so many years, and this is the first time he has heard of this term.

Of course, from the name, he can probably understand what it is. It's just that this device doesn't seem to have any precedent, which is equivalent to starting from scratch. Not to mention the difficulty, controlled nuclear fusion itself is a super difficult problem. If you start from scratch, who knows when you can get some results.

Xu Chuan nodded, his eyes were a little erratic, as if he was lost in memories or other things, but this did not delay his communication with Peng Hongxi.

"Although the tokamak and stellarator have developed into two almost completely different fusion devices, if we put aside the differences in shape, they are actually both made based on the principle of magnetic confinement."

"The advantage of the stellarator is that it can directly generate a twisted toroidal magnetic cage through an external coil, thereby enhancing the confinement of the plasma, but the tokamak cannot do so because its structure itself cannot do so."

"But what if parts of the two are combined to make a new fusion device?"

"The multiple magnetic mirror tight ring control device is a new device conceived based on this concept. It is a new thing made by further optimizing the tokamak device and the stellarator device and combining part of the spherical bed design."

After a pause, Xu Chuan regained his attention from his distraction, smiled at Peng Hongxi, and added: "Of course, it only exists in my mind at present."

Indeed, the multiple magnetic mirror tight ring control device only exists in his mind at present, but it will not be in the future.

In his previous life at Princeton, he received support to transform the spherical torus experimental magnetic fusion device (NSTX-U) of the Princeton Plasma Physics Laboratory.

The modified NSTX-U was upgraded to NSTX-UX1, and NSTX-UX1 achieved fusion reaction control for up to 30 minutes.

He participated in the whole process of this project, so he was fully confident about how to adjust the fusion equipment.

Of course, NSTX-UX1 is an optimization based on room-temperature superconducting materials, so before that, he had to get the superconducting materials out first.

On the other side, after listening to Xu Chuan's explanation, Peng Hongxi couldn't help but frowned.

"I don't know what the fusion device you conceived is like, but I have to remind you that a device with a complex and twisted shape is most likely not suitable for controlled nuclear fusion, and the plasma turbulence in the internal chamber is not so easy to control."

Peng Hongxi felt that Xu Chuan was a little whimsical, maybe because he was too young, and he had solved all the problems smoothly along the way, so that his thoughts on controlled nuclear fusion were so jumping.

Of course, he has such qualifications.

At the age of 21, he won the Nobel Prize and the Fields Medal, two of the top awards. In addition to his research on nuclear waste, it is not an exaggeration to say that he is the first in the Chinese scientific community or even the world scientific community.

It is just a combination of tokamaks and stellarators, and then the spherical bed is cut and fused together to make a new fusion reactor device. It is not known whether there will be successors in the future, but it is definitely unprecedented.

For all aspects, he must at least remind that controlled nuclear fusion is not so easy to solve.

He does not want to see the young man in front of him squandering the country's resources and money because of his ideas.

Perhaps this is indeed a feasible path, but based on his decades of experience in controlled nuclear fusion, not to mention that it cannot be realized, even if it can be realized, trial and error on a brand new path will probably cost countless funds.

Xu Chuan smiled and said, "What if I have a way to solve and control the plasma turbulence in the reactor chamber?"

"That's impossible!"

Peng Hongxi refuted without thinking, but then he was stunned, staring at Xu Chuan without blinking, and his breathing became heavy involuntarily.

He suddenly remembered that the man in front of him had pushed the NS equation to a new height in the first half of the year, and the proof paper had been published in the "Annals of Mathematics".

This result is being studied by the mathematics, physics and even industry. It can be said to be the hottest emerging field in the current scientific field, because it solves the difficult problems in the field of fluid mechanics and has great help to the development of science and technology.

But if we talk about who is absolutely top in this field, I'm afraid no one can match the young man who has pushed the NS equation to a new height.

"Have you found a way to control plasma turbulence?" Peng Hongxi asked in disbelief, breathing heavily and trembling slightly.

Xu Chuan smiled and said, "In theory, I have indeed found a way to model plasma turbulence. The results were made not long ago and have not been made public yet. Do you want to see it?"

"Where is it? Of course."

Peng Hongxi asked quickly. If he had not forced himself to sit on the sofa, he would have stood up directly. In this case, he continued to lean forward, as if the closer he was, the closer he would see the solution.

Xu Chuan just wanted to get up and go to the study to get the manuscript paper, and he slapped his head. His previous research was still at Nanjing University. He had not had time to get it back these two days because he was dealing with issues such as the location of controlled nuclear fusion.

"The manuscript paper is in the office at Nanjing University. I'll call my students to send it over. It should be delivered in ten minutes." Xu Chuan smiled embarrassedly, took out his mobile phone from his pocket and called Gu Bing.

"Hello, Gu Bing, are you in the office?" After dialing the phone, Xu Chuan asked quickly.

"Yes, professor. What's the matter?" Gu Bing replied quickly.

"There is a manuscript paper held together with a long-tail clip in the drawer of my desk. Please help me deliver it to my villa."

"Okay, wait a moment." Gu Bing answered on the phone and stood up and walked towards the tutor's desk.

After flipping through the drawer, Gu Bing's doubtful voice came from the phone: "Professor, are you sure it is in the drawer? I searched the three layers of drawers, and there is no manuscript paper held together with clips as you said. There are only some unused A4 and pens?"

"No? No, I remember putting it in the drawer." Xu Chuan had a question mark on his face. Did he remember it correctly?

When modeling plasma turbulence before, because I needed to use those theoretical foundations, I just clipped it with a clip and put it in the drawer for my own use.

"Really not, did you take it back, professor?" Gu Bing replied affirmatively. He searched all three layers of the drawer in front of him, but didn't see the manuscript paper or anything like that the tutor said.

"Strange, okay, I know." Xu Chuan responded and hung up the phone.

"What's wrong?" Peng Hongxi asked quickly after seeing Xu Chuan hang up the phone.

"The manuscript paper I put in the office seems to be missing. Maybe I brought it back here?"

Xu Chuan replied uncertainly, got up and walked towards the study.

He clearly remembered it correctly, could it be that he really brought it back?

Usually he does research in the study of the villa or in the office of Nanjing University.

After the nuclear waste project was completed, he had to make up for the classes he had missed before, so he spent more time in Nanjing University.

It didn't make much difference to him. Nanjing University also had an independent office anyway. There was no one else except Gu Bing and Amelia.

"The manuscript paper is missing?" Peng Hongxi looked at Xu Chuan in confusion. His first reaction was, "What a coincidence?" After all, they were both talking about this thing just now.

Xu Chuan: "Maybe I brought it back here. I'll look for it first."

Hearing this, Peng Hongxi also stood up and followed him to the study room, watching Xu Chuan bending over and searching everywhere in the study room.

After a while, Xu Chuan stood up, scratched his head, smiled awkwardly at Peng Hongxi, and said, "It seems that there is nothing here either. I'll call and ask again."

Then, he called Gu Bing again.

"Hey, Gu Bing, ask Amelia if she has touched the manuscript paper in my drawer?" Xu Chuan asked.

Gu Bing asked and quickly replied: "No, we don't usually touch your things, and we won't touch your desk when we clean."

"That's strange."

Xu Chuan looked confused. He clearly remembered that the manuscript paper was in the drawer of the desk. If he brought it back, it wouldn't be in the study. He couldn't throw such things anywhere else.

As for what Gu Bing and Amelia lied about, it basically didn't exist, after all, there was no need.

"Do you want to go and take a look together?" Peng Hongxi asked.

Xu Chuan nodded and said, "Okay."

After calling Zheng Hai, Xu Chuan and Peng Hongxi quickly rushed to Nanjing University.

"Professor, Academician Peng."

In the office, Gu Bing and Amelia were doing their own research. When they saw Xu Chuan and Peng Hongxi, they quickly stood up and greeted them.

Xu Chuan nodded, walked to his desk, and opened the drawer.

The scene in front of him made him stunned for a moment, and then quickly flipped through other drawers.

In the empty drawers, not only the manuscript paper that was clipped together with a binder clip, but also the messy and unorganized manuscript papers were gone.

His office seemed to have been robbed?

Someone took away the manuscript paper he put in the drawer, not only the theoretical results, but also some other manuscript papers.

Now the entire three-layer drawer is clean, except for a few pens and a stack of brand new A4 paper, nothing is left.

This incident has a prototype. Hua Luogeng must be familiar to everyone. His manuscripts were stolen, and they were stolen from the School of Mathematics of the Chinese Academy of Sciences.
