In nuclear fusion, the deuterium-tritium reaction requires the lowest temperature and pressure, tens of millions of degrees Celsius is enough, and tens of millions of degrees Celsius can also be fusion if the pressure is sufficient.

The temperature requirement for helium-3 fusion reaction is more than 100 million degrees, the deuterium-deuterium reaction needs more than 500 million degrees, and the most common light element hydrogen requires more than 1 billion degrees Celsius to produce a fusion reaction.

Of course, the mathematical model of plasma turbulence does not need to evolve to such a high level, and the data has shown that the higher the temperature, the smaller the difference in plasma turbulence between the two temperature ranges, and when a certain temperature above a certain limit is reached, there will be no difference in plasma turbulence.

Nine days later, Lin Meng and Zhang Qing, who were a little tired, put down the pen in their hands and finally breathed a sigh of relief.

12,983,679 degrees Celsius!

Finally, starting from this temperature range of 12,983,679 degrees Celsius, the data of plasma turbulence no longer changes.

After integrating the idle performance resources of the IDC data centers and data centers of the three major operators, coupled with the previous supercomputing network, the calculation time in each temperature range was shortened to 2 minutes and 53 seconds, less than 3 minutes.

The further I go, the more proficient I am in the application of the mathematical model, and the time to construct the mathematical model for the next temperature range from the first 23 minutes to the back is shortened to more than 9 minutes.

"The tokmak parameters of the EAST project were sent, and we converted the mathematical model into a model suitable for this tokmak, improved the control algorithm of the device, and verified whether the data was accurate."

A mathematical model of plasma turbulence with controlled nuclear fusion temperature has been constructed, but this is not the end, and the relevant data of the mathematical model still need to be verified in practice before it can be calculated.

After a short break of less than two minutes, Zhang Qing took a USB flash drive and inserted it into the computer, and Lin Meng and Lin Meng quickly converted the mathematical model data according to the parameters of the tokmak device above.

After two mathematics professors from CUHK came to help build a mathematical model together, Lin Meng and Zhang Qing took the time to prepare, and now they are really handy in doing it.

"Hey, Uncle Zhang, I've got it done here, let the EAST project get ready, and the relevant data and control algorithm parameters that need to be changed will be sent over later."

Seeing that Lin Meng and Zhang Qing were busy, Lu Yi also took out his mobile phone and called Uncle Zhang.

After 1 hour and 28 minutes, the relevant mathematical model was converted into a model of the Tokmak device suitable for the EAST project, and the corresponding control program algorithms were completed.

The data package is sent out through the high-speed dedicated line, and the EAST project, which has long been ready to go, adjusts the control program of Tokmak according to the data as soon as possible, and then starts the device to start verification......

"Lu Lu, do you think it will be successful, how is the Max Planck lab over there?"

The waiting time seemed to be very long, and Zhang Qing asked Lu Yi next to him a little restlessly.

"There must be no problem, if the data level verification is correct, but the actual is wrong, then there must be a problem with the actual Tokmak device, as for Max Plano's side, it must not be so fast, as far as the computing performance they applied for, it is comparable to our supercomputing network, quantum computers, and IDC computer rooms and data centers backed by 1.3 billion people."

Lu Yi calmly comforted, but the hand in his pocket couldn't help but clench quietly.

He didn't dare to take a peek at the scientific strength of Max Planck Labs, let alone have two Fields Medal winners over there, and maybe he couldn't automate the reciprocating operations here, but they didn't have a problem at all.

Originally, when the temperature range model data was disclosed, Lin Meng did not have a clue about the evolution model, so in addition to whitewashing public opinion, there was also the idea of using the hands of other laboratories to jointly solve this problem.

Unexpectedly, Professor Lin stayed at home for half a month during the Chinese New Year, and she really found a clue about the evolution model, and she had the qualifications to eat alone, but the original model that was thrown out became the capital for others to cut off the beard.

If Professor Lin didn't find a clue, it would be good if there was a breakthrough on Max Plan's side, Lu Yi admitted, how to say that this experimental idea and the mathematical model of the temperature range were proposed by his own side, and whoever completes it will have benefits.

But now that I've completed the evolution model, it doesn't feel the same way.

It's like a treasure chest, throw it out if you can't open it with all your might, and you want to use the power of everyone to open it for your own share, but you don't think that you just threw it out, but suddenly you find a way to open it......

Tick tick!

After two hours of hard work, the computer suddenly sounded and a new email was sent.

You were the shadow to my life......

"Hey, Lu boy, it's really yours, it's really done by you!"

Before Lin Meng and Zhang Qing could open the email to check the content, Lu Yi's mobile phone rang, and Uncle Zhang shouted happily on the other side of the phone.

Done?

Lu Yi was stunned for a moment, ignoring Uncle Zhang, who didn't pay attention to the information on the phone, and hurriedly shouted to Lin Meng and Zhang Qing: "Hurry up and sort out the verified data, send the paper to the PRL physics journal, and send another copy to Yashan, and directly publish it on the Internet around the world." ”

......

Drip!

In Max Planck's lab, Professor Andre made himself a cup of coffee, and before he could take two sips, the computer in front of him suddenly sounded the voice of receiving an email.

Putting aside the coffee in his hand, Professor Andre clicked on the prompt email, which was the message fed back by the bot on the other side of the computing network.

"Huh?"

After just one glance, Professor Andre showed a hint of joy in his eyes and shouted: "Tessky, the results of the calculation are out, the difference completely disappears when the plasma turbulence temperature reaches 12,983,679 degrees Celsius, and the turbulence data behind it no longer changes."

Old man Rupert, Tesky and I are sorting out the data to improve the control program algorithm, and you are going to start the stellarator for data verification. ”

Lu Yi guessed correctly, they can't realize the program automation reciprocating operation for the time being, but on the Max Planck Lab side, the two Fields Medal winners plus the Max Planck Lab engineers themselves have a certain mathematical strength, and there is no difficulty in automating the entire calculation process at all.

"According to the parameters of the stellarumer, the current intensity of coils 034 to 059 is reduced by 0.13 percent, the current intensity of coils 176 to 201 is increased by 0.03 percent, and the current intensity of coils from 1674 to 1679 is reduced by 0.36 percent...... The power of the deflector in zone A is increased by 2.8%, and the power of the debiaser in B is increased by 1.9......."

André took a sip of coffee and quickly adjusted and determined the new control parameters and control algorithms according to the mathematical model of controllable fusion plasma turbulence calculated by supercomputing, and according to the original control parameters of the stellar simulator to be started.

After spending less than twenty minutes to complete the new control parameters and control algorithms of the stellarator, it seemed that he had seen the future of controlled nuclear fusion become a reality, and the names and contributions of himself and others would forever be etched in human history.

"Tessky, hurry up, it's time for our paper to be published." Send the new control parameters and algorithms to Kreber for practical verification, Andrei shouted to Professor Tessky.

He is confident that he does not need to wait for the actual verification results of the stellarator.

As a world-class math master, he has long believed that mathematics is the truth of everything, and the data level has passed, if the reality does not pass the verification, it must be a problem in reality.

"Tsksky, man, hurry up, the Haven lab also applied for computing resources a few days ago, and we need to get the paper published before they go, Tsksky? What happened to you? ”

Andrei shouted several times in a row without getting a reply from another math boss, Teskey, turned his head to see him looking at the computer motionlessly, and hurriedly walked over to check if this guy had a sudden myocardial infarction.

"Andrey, maybe we don't have to publish our paper......" Tessky pushed his computer forward, his eyes full of unwillingness, but he had to sigh and lean back in his chair.

"What?"

Andre leaned in front of the computer, and the information displayed on the screen made him suddenly feel his heart tighten, and his heart muscle felt like ischemia.

"A major breakthrough has recently been made in the research on plasma turbulence led by Professor Lin Meng, and a mathematical model of controllable fusion plasma turbulence has been successfully constructed, which has successfully exceeded 300 seconds for the Tokmak device of the Huaguo EAST project!" 》
