After the last reunion of friends in the junior dormitory, Lu Yi drove back to the laboratory.

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

"Senior Sister Xu Ying, what's wrong?" Just halfway back, the mobile phone suddenly rang, and Xu Ying called.

"Lu Lu, the Gang Max Planck Laboratory issued a notice that the confinement time of the Spiral Stone 7-X plasma exceeded 190 minutes, and it is planned to start the formal test construction of the DEMO demonstration reactor."

"What?" Lu Yi was startled, and subconsciously raised the accelerator with his right foot.

The speed of the car slowed down, and after looking at the passing vehicles, Lu Yi frowned and said, "Let Zhang Qinglinmeng, Hu Feng and those two engineers go to the conference room together, and I will go back in about 15 minutes." ”

"Okay." Xu Ying responded.

15 minutes later, Lu Yi returned to the laboratory, and Zhang Qinglinmeng was already waiting in the conference room.

"Lu Lu, I think this may be a cover, this data of plasma confinement for 190 minutes has been verified to be true, but the construction of the DEMO demonstration reactor is very likely to be fake, and it is a plan to interfere with other controllable nuclear fusion laboratories."

Seeing Lu Yi coming in, Zhang Qinglinmeng, who was looking at the experimental data of Max Plank's laboratory, raised his head and said.

The breakthrough in the plasma turbulence model has allowed the capital and academic circles to see the dawn of nuclear fusion, and since then the major nuclear fusion laboratories have entered the competition.

Capital is invested, researchers are expanded, everyone is catching up, and some means of interfering with other laboratory plans are no problem.

Because the benefits involved in controlled nuclear fusion are too great, even if the environment is driven by whoever takes the lead in making a breakthrough, all countries need to share it, but this sharing is not free of charge, and the first institution and country to grasp the opportunity to master the patent will get huge benefits from it.

"It won't be fake, if it's fake, they can't hide the power of capital."

Lu Yi shook his head, it had only been a few months since Max Planck Lab felt the power of capital, and it was impossible to think that a false plan could hide from capital.

If they know that they can't hide it, they won't be stupid enough to adopt a false plan, which will be a big loss of their reputation and prestige in the academic world.

"Lu Lu, the Spiral Stone 7-X should have undergone further improvements, according to the parameters provided by the two Bakers before, I have combined the plasma turbulence model for mathematical modeling analysis.

Even if the original Spiral Stone 7-X had a plasma turbulence model, 130 minutes was the limit, and any higher it would melt the first layer of inner wall material. ”

Lin Meng said the results of a mathematical modeling analysis he had conducted before, suggesting that the Spiral Stone 7-X stellarator must have undergone significant improvements.

This improvement does not mean adjusting the control scheme and adjusting the parameters of the external magnetic field coil, but involves the fundamental improvement of the stellarator.

For example, the replacement of inner wall materials that are more resistant to plasma temperatures, the value-added cladding that can persist in neutron radiation for a longer period of time, or the external magnetic field coil that can generate a stronger and more stable magnetic field, and a more efficient deflector, etc.

"Brother Hu, our superconducting graphene wire hasn't been sent over yet, has it?"

Lu Yi tapped his fingers on the table, and suddenly turned his head to look at Hu Feng.

"Not yet, I plan to send it tomorrow, don't you plan to send it again?"

"Send it, why don't you send it."

Lu Yi shook his head, turned his head and asked the two Baker engineers in English: "Beck, when you were in Max Planck Laboratories before, did you know if there were any other hidden and unused technologies in the research of Spiral Stone 7-X, or other research plans?" ”

The two Baker engineers looked at each other, thought for a while and replied: "The technology will not be hidden, at that time, the stellar project funding was limited, and the laboratory needed to give investors hope, so once the new technology conditions are ripe, it will be applied as soon as possible."

However, the laboratory once had a backup plan for the delay in the breakthrough of better superconducting materials, resulting in the inability to increase the magnetic field strength and causing the first inner wall material to be seriously irradiated by plasma.

Perhaps this backup solution can explain the current situation of Spiral Stone 7-X. ”

"What's the backup?"

"In front of the first inner wall material, add one or more layers of active plasma-resistant irradiation material that wraps the magnetic confinement track, and use this material to bear the plasma penetrating the magnetic field first, and reduce the pressure of the first inner wall in the rear."

"Can this kind of plan be realized in engineering?"

Lu Yi and the others glanced at each other, as we all know, the stellarite process is precise, and the annular orbit that constrains the magnetic field is distorted and irregular.

The high-precision, twisted and irregular doughnut, coupled with the precision of the entire stellarumer, is divided into various functional layers, as well as an external magnetic field coil.

In this way, it is conceivably difficult to create such an active interlayer between the first inner wall material and the magnetically confined track.

"Yes, the magnetic field confines the orbit to compress inward or the first inner wall to move outward, which can give space for activity.

The external magnetic field coil is not tightly integrated, and the space between some coils can also meet this scheme, so there is no need to change the coil scheme.

As for the irregular twisting of the track, this does not affect because the sandwich material is wrapped around the outer diameter, like a piece of cloth to wrap a swimming ring.

Because it can come out to cool down after running a circle, the thermal conductivity of this layer of material does not need to be too good, as long as the penetration of neutrons is ensured to meet the needs of the tritium proliferation cladding layer behind.

With such relaxed conditions, the range of materials to choose from will be very large. ”

Baker opened his laptop and connected it to the projector, and then opened a dynamic diagram inside.

A twisted and irregular doughnut is a metaphor for the orbit of a stellar mimic plasma, with a layer of chain-like or woven cloth coming through a opening, wrapping around clockwise and exiting through the opening.

"This scheme could not be realized before, because the plasma turbulence model was not broken through at that time, and the optimization of the control scheme failed, resulting in too serious plasma irradiation, and the interlayer melted before it could run a circle.

Now that the plasma turbulence model allows the control scheme to be optimized, the plasma irradiation intensity is greatly reduced so that the material can withstand for a longer period of time, then there is room for this solution, according to our calculations, this layer of material can reduce the radiation of the first inner wall by 40 to 60 percent. ”

After listening to Beck's account, Lu Yi, Zhang Qing and the others were a little silent, can the stellar mimic still play like this? This engineering design and industrial precision are too unbelievable.

"Lu Lu ......"

Xu Ying, who was taking minutes of the meeting next to her, suddenly said: "If that's the case, then our tomorrow's stellar simulator can also adopt this plan." ”
