Chapter 548: In full swing

Early October.
The entrance of the base was a bit hilarious.
I saw that beside the construction site, several heavy trucks were parked there. With the assistance of the site construction staff and lifting equipment, they had carefully completed the unloading work.
Standing next to Lu Zhou, watching the heavy equipment transported into the base, Xiao Le said with emotion.
"It was originally sold to iter, but they probably won't buy it now."
The device in front of the two of them is the legendary icrf heating antenna.
This device consists of a transmitter, a transmission line, an impedance matcher, and the most critical heating antenna. rf output energy can reach 3mw level, frequency adjustable range is between 30-110mhz.
As one of the key components of the fusion device, this gadget can be said to be the second largest black technology in addition to the full superconducting d-type cross-section design of the Luyang Material Research Institute.
In addition to being purchased by General Atomic Energy, this billion-dollar facility also received orders for iter demonstration reactor projects.
But now it seems that Europeans will probably not buy it.
After a pause, Xiao Le continued: "This equipment was originally intended to be shipped to France after disassembly, but our cooperation with them has been interrupted. With this gadget, we can quickly remove the plasma inside the reactor Heating to more than 100 million degrees, it can be said that this is one of the most advanced plasma heating technologies in the world! "
Lu Zhou nodded and looked at the device with interest.
Although the name is icrf heating antenna, compared to the antenna antenna he understands, this thing is more like an air conditioner that is enlarged by dozens of times.
The reinforced support under the entire device is not much different in shape from the reinforced support that is lifted under the air conditioner. The forwardly protruding protection limiter and current band in the entire device are like the combination of air conditioner filters and fan blades.
Further to the back are tubular vacuum transmission lines, hydraulic drives, and critical vacuum feeds.
In the experiment, the protection limiter as the "air conditioning fan blade" is located at the forefront of the icrf heating antenna. Together with the current band next to it, it forms a plasma heating component and a "Faraday shield box". While heating the plasma Isolates the plasma from the current band while preventing the electrostatic field from coupling into the plasma.
Because it directly faces the plasma in the vacuum chamber, 43 cooling pipes with an outer diameter of 10 mm are also welded on it.
Although the entire device looks complicated and huge, and lacks some sci-fi beauty, no single design is superfluous on the entire device, and even each welding joint has been carefully designed.
Therefore, it is not easy to change these designs.
At this time, an old engineer with a hard hat and a gray coat came over and looked at Lu Zhou with a smile.
"How's it going? It looks ok, right?"
After hearing this, Lu Zhou smiled and said, "It looks quite reliable, but I hope it can run normally on the stellar."
The old engineer waved his hand: "You can rest assured that even if it doesn't work now, I promise to make it work."
The old gentleman standing in front of Lu Zhou is named Li Jiangang, a member of the Chinese Academy of Engineering, and also the vice president of the University of Science and Technology and the vice president of the Institute of Material Research of the Chinese Academy of Sciences.
Although the old man was studying ship power undergraduate, somehow he started studying plasma physics halfway. Later, he caught up with the tide of major scientific projects in the Ninth Five-Year Plan. The research on controllable fusion has become more and more important in China. His academic career can be considered as a peaceful development along with the development of the historical process. Later he was rated as an academician.
Before Hua Guo retired from iter, he was still a member of the Hua Guo Expert Committee. ICRF heating antenna technology can be widely recognized internationally, and his credit is also indispensable.
As for now, Hua Guo has retired from iter, and his status has become a consultant of the National Fusion Energy Program Implementation Center, and is responsible for coordinating the work of the Luyang Material Research Institute in the demonstration reactor project-that is, the entire demonstration reactor. Heating parts.
Xiao Le, who was standing next to Lu Zhou at the moment, was his student, and it was he who recommended it.
Lu Zhou still believes in this big cow's guarantee.
"It's bothering you, then I will simply say a few requirements."
Professor Li took out the notebook he took with him and did not make nonsense.
"You said."
Lu Zhou nodded, recalling the engineering details that had been discussed at previous meetings for a while, and said.
"Corresponding to several different types of plasma in the stellar discharge experiment, the heating antenna needs to be able to move in the radial direction, with a range of negative 150 mm to positive 150 mm, and the adjustment accuracy is one millimeter. It can be done ?"
Professor Li thought without hesitation: "This problem is not big."
Lu Zhou nodded and continued.
"The characteristic impedance requirements of natural vacuum feeders, transmission lines and other components must meet the design requirements of 50Ω, and the allowable voltage requirements of the inner and outer conductors are 45kv."
"The current band and Faraday shield both need to be designed with independent cooling circuits, and their cooling capacity is required to be able to withstand thermal loads at the level of mw / m2."
"Also, while considering the assembly and maintainability of the antenna, while minimizing the welding parts, it is required to ensure that the total leakage rate of the antenna is less than 10 ^ -10pa · m ^ 3 / s."
"..."
At first, Academician Li's expression was still relaxed. However, after listening to the landing boat Lianzhu Cannon, it seemed that his relaxed smile gradually disappeared on his face, and he felt scalp tingling for a while.
Then I said a dozen pieces of requirements piece by piece. I felt a little thirsty land boat, took mineral water from Wang Peng's hand, drank it, threw the plastic bottle back, and then added it later. One sentence.
"... The basic situation is like this. I might say a little bit faster. When the outline of the meeting is to be done in the evening, I will send you more specific requirements."
Hearing this latter sentence, Li Jiangang stopped the pen in his hand.
Staring at the notebook in his hand for a while, his brows frowned for a while, and finally a narrow smile came out of his face.
"... You really will give us problems, and it's not as many things as you do in the European engineering bidding conference."
After hearing this, Lu Zhou smiled lightly and said, "After all, it is the first reactor. A good start can only make a good demonstration. I want to make it as perfect as possible."
Although the system does not specify specific "acceptance criteria" for the demo demonstration reactor, there is no doubt that the task reward is directly proportional to the results. The more powerful this demonstration is, the higher the mission reward will naturally be.
What's more, from a practical point of view, the stronger the performance of the demonstration reactor, the smaller the resistance encountered in the technology promotion stage. From the perspective of a researcher, he also hopes that his research can be recognized by the country and the world.
Closing the notebook, Academician Li said, "Okay, wait until tomorrow's business is done. I'll have a meeting in the institute to study and give you results in two days."
Lu Zhou nodded: "Well, please."
...
After the last work was arranged, the work on the star-2 demonstration reactor base was basically on track, and it was in full swing on the project site and in the institute.
The demonstration reactor is like a torch, illuminating the future of the entire domestic nuclear fusion research.
Even if there is no impassioned mobilization speech, everyone working here has a strong sense of mission.
They are doing a great job.
Their research has moved ahead of the world.
Until now, under the leadership of the project leader, they have achieved countless staged results, achieved countless victories, and proven themselves countless times.
In addition, everyone has no doubt that as long as the designer Lu is present, they will continue to win until they cross the final finish line.
In such a working environment, it is difficult to generate negative emotions.
It can be said that even the chefs in the cafeteria are working with enthusiasm.
If things are optimistic, all components can be completed years ago.
As for whether it is before New Year's Day or before the Spring Festival ~ EbookFREE.me ~, it depends on luck.
For Lu Zhou himself, there are only two things that he needs to solve now.
One thing is to go back to the Star Imitation Research Institute on the side of Zijin Mountain and use the star experimental reactor device to complete the final design of the liquid lithium neutron recovery system as soon as possible.
Others are so powerful, they can't hinder themselves.
As the most core component of the entire nuclear fusion reactor, it can be said that the design of this part directly determines the success of the star-2 demonstration reactor project. If this part is completed, following the "plasma control technology", he will overcome the second major obstacle of controllable fusion: "stagnation retention".
At the same time, this is the last difficulty.
As for what unit to use to generate electricity, what device to use to generate heat, and install "insurance" under the reactor, etc., all these structures just decide whether the fruits of victory can be more perfect.
As for the other thing, it is to solve the problem of supercomputing algorithms.
At present, the plasma control of the star experimental reactor is completed with the assistance of Xiao Ai.
When the demonstration reactor is completed, he can't get Xiao Ai to the main control computer of the demonstration reactor, right?
After all, no matter from what angle, Xiao Ai is not suitable for showing up in front of people, at least not right now.
Ideally, the algorithm related to the plasma control scheme is separated from its main program.
If these two problems are solved, then all the "puzzles" are assembled.
The completion of the demonstration reactor is just around the corner.
Thinking of this, Lu Zhou's heart could not help but feel a little feverish.
Countless days and nights of effort.
This day is finally about to be waited for by him.
