Institute of Plasma Physics, Chinese Academy of Sciences.

Highly confined plasma discharge is an advanced and efficient operation mode preferred for magnetic confinement fusion reactors in the future.

Since the 80s of the last century, many tokamak devices around the world have been exploring various ways to achieve high-confinement discharge, and constantly trying to extend the high-confinement discharge time.

The advancement of any scientific program will inevitably encounter difficulties, and the same is true for the Oriental Superring Program.

In the research room of the center, Song Lizhang and a group of scientists are discussing issues such as high-confinement discharge and extending the discharge duration.

After Ding Sheng came here, he didn't disturb the conversation of the scientists, but chose to stand aside silently and wait for Dean Song to find time.

"At present, the high-confinement discharge time of tokamak devices in operation around the world is less than 10 seconds, and only the JT-60U device in Yamato-kuni Province has achieved a high-confinement plasma discharge of 28 seconds by using strong current neutral beam heating in 2003.

"The stability of the JT-60U device is too poor, and the input cost is too large, the economy is too low, and the people and money are lost. ”

"In the end, it is too short to maintain the plasma duration of the deflector at 20 million degrees, it would be nice if it could reach more than 200 seconds."

"Let's change the control accuracy of some plasma first, and try more solutions. ”

After no discussion for a while, Dean Song asked everyone to continue the experiment according to the plan proposed earlier, hoping to obtain some useful data and information in the experiment.

The experimental cycle of the Oriental Super Ring Project is initially expected to be within four months, and there is a way that you can't eat hot tofu in a hurry, and the same is true for science.

At this moment, Ding Sheng silently raised his little hand.

"I have a suggestion. ”

Ding Sheng didn't mean to eavesdrop on the conversations of these scientists, nor did he plan to do the same, after all, according to Dean Song's progress, they could completely solve these problems within four months, and they didn't need him to do anything at all.

But he came here today to ask Dean Song about the problem, the so-called coming without being rude, since he has already heard it, why not give it a touch.

"Ding Sheng, if you have any ideas, just say. ”

Song Lizhang has heard Ding Sheng's anecdotes from Yang Huaigu and Chen Tingqiu, this kid has put forward effective suggestions at critical moments of major meetings more than once, and in the end, there is no doubt about his personal ability.

Having said that, even if there is no respect from the two academicians, Yang and Chen, Dean Song Lizhang knows his fate and has the world in mind, and he will definitely not ignore the academic proposals of others, even if the other party is just a young graduate student.

"At present, under the premise of precise plasma control, can the synergistic effect of low clutter and radio frequency wave achieve stable and repeatable high-confinement plasma discharge under low recirculation conditions?"

For Ding Sheng, the meaning of this sentence is completely "will 3 2-5 be equal to zero under normal operation"?

He joined the question, just not wanting to make himself look too inhuman.

Ding Sheng's words, like every previous time, really made everyone present fall into deep thought.

"Although this proposal will involve the safe operation of fully superconducting magnets, effective heating and drive, and plasma-wall material interaction, it is generally feasible. ”

According to the strength level, Dean Song was the first to react and couldn't help nodding.

A word wakes up the dreamer.

Soon, after other researchers cleared their minds, they also agreed with Ding Sheng's proposal.

As for the problems that Dean Song just said, of course, Ding Sheng can also immediately propose specific solutions and end the Oriental Super Ring plan ahead of schedule, but in this way, he seems too incredible to explain the following problems.

"Ding Sheng, I really didn't expect you to have such a deep study of the tokamak device, can you tell me how you came up with this plan?"

With the new plan, Dean Song still didn't forget to ask questions in his busy time, so everyone's ears in the central research room were pricked up, and they all wanted to hear Ding Sheng's answer.

"Since joining the team, I have been studying the papers and materials on tokamak devices from all over the world in recent decades. ”

Ding Sheng could speak, and while explaining things clearly, he also praised everyone in the research room.

I like that.

For a time, in the minds of everyone, Ding Sheng had jumped from a well-known mechanical engineer to a genius boy in the field of controlled nuclear fusion.

With a little cultivation, it is the blessing of China.

You must know that Ding Sheng is only a graduate student, and many academicians, professors, and senior researchers have already made a small calculation in their hearts, and are ready to invite him to his own school or scientific research institution to study for a doctorate.

"Ding Sheng, are you interested in staying at the Institute of Plasma Physics to continue your studies?"

It's a pity that before the others have time to speak, Song Lizhang has already killed the game first and threw out the olive branch of the doctorate.

"Academician Yang, you don't have to worry about it, there are a lot of double bachelors and doctors in Huaxia, and after you finish here, it's not too late to go to the machine response laboratory. ”

Yang Huaigu is Ding Sheng's teacher, as long as the development of quantum radar in Yuzhou is completed, it is natural for Ding Sheng to become a doctoral student.

It's just that who doesn't like talents, not to mention that they are still geniuses, Song Lizhang can be regarded as the first to strike.

What's more, the Plasma Physics Research Laboratory is directly affiliated to the Chinese Academy of Sciences, and even if Ding Sheng is studying for a doctorate here, he will still be a member of the Chinese Academy of Science and Technology in the future.

Although Song Lizhang is the president of the Chinese Academy of Sciences, he doesn't want to be found fault by the old people in the academy, such as Li Chunbai and Yang Huaigu.

And other researchers who were willing to invite Ding Sheng were also dead set upon at this time.

Not to mention that Ding Sheng will most likely not refuse Dean Song's invitation, even if he refuses, Dean Song will dig the corner of Yang Huaigu and Li Chunbai, and he will still show his old face

There are not many other people here who dare to think cranky.

"Good. ”

Of course, Ding Sheng had to agree, didn't he deliberately show a wave just now just to get close to the relationship, and besides, he finished the degree he should have taken earlier, restored his "free body", and returned to the base camp of the neighboring state to develop is the king.

Dean Song nodded with satisfaction, a smile on his face.

"You said on the phone that you were looking for me something, what is the matter?" After handing over the work to the other researchers, he took Ding Sheng to an office, and Dean Song asked.

"Then can I say it directly?" Ding Sheng said bluntly, but in fact, he was still tempting.

Say. ”

"The industrial equipment of our space-time technology in the major state-owned enterprise machinery groups has been stopped at the same time, do you know what is going on, Dean Song?"

Of course, Ding Sheng knew that it was because Catherine Oxton cut the line, and the reason why he asked like this was just to make a joke.

When Dean Song heard this, he didn't look out of the ordinary, but laughed, "What should I do, I know about this, yesterday Liang Shuang brought Catherine's girl to the Chinese Academy of Sciences, saying that the United States was willing to exchange technology, and asked us to help make a batch of experimental equipment immediately, and after discussion in the academy, they agreed." ”

"Liang Shuang, Catherine?" Ding Sheng said curiously.

"Liang Shuang, you should have seen that after the new controller was launched, she was fully responsible for scheduling. Catherine is a genius physicist in the United States, and at the same time a very pure scientist, she is very powerful. ”

Song Lizhang paused, thought about it, and finally didn't come up with any more suitable words.

"And what about the technology that the United States uses in exchange?"

Spare such a big circle, this is the main purpose of Ding Sheng's coming here today, if you want to cut off Catherine Oxton's research, the simplest and rude way is to draw money from the bottom of the kettle and make it difficult to give birth to the equipment she wants.

Then this technology as an exchange is the key.

"Space engines. ”

There was a little difference from what Ding Sheng expected, but he didn't expect Dean Song to say it directly without a little hesitation. u
