Li Wu took a long breath and calmed down. The excitement and tension in his mind began to disappear little by little, replaced by calmness. At this moment, girlfriends, soldiers, professors, nuclear bombs, etc. all disappeared from his mind.
Now, he only has work in his eyes.
This is just a slightly complicated job, just do it as usual and complete it, that's all.
The helium-3 bomb is more complex than ordinary hydrogen bombs. It adopts a three-layer ring structure. The innermost layer is the atomic bomb, which is the one transported by the two soldiers; the middle layer is deuterium and tritium, which are the main materials of the hydrogen bomb.
;The outermost layer is helium-3.
In Professor Ding Yidong's design, the innermost atomic bomb detonates first, generating a high temperature of more than 50 million degrees, which ignites the outer layer of hydrogen bombs. Then, the high temperature of 100 million degrees generated by the detonation of the hydrogen bomb ignites the outermost helium-3
layer.
Compared with hydrogen bombs, helium-3 nuclear bombs actually only have an extra outermost helium-3 layer, but don't underestimate this extra layer. Its technical difficulty has increased several times.
Why? First, helium-3 is usually in a gaseous state. Although it can be compressed into a liquid state under high pressure, it still needs a large refrigeration device to store it for a long time. This is too troublesome. A small nuclear bomb certainly cannot be equipped with it.
This kind of thing.
Moreover, helium is an inert gas and basically does not react chemically with anything. How can it be converted into a solid state?
Professor Ding Yidong has been studying for ten years and finally solved this problem, that is, the physical adsorption method. He invented an activated nanocarbon that can absorb a large amount of helium-3 gas at low temperatures. etc.
Return to normal temperature and the adsorbed gas will not be released.
Okay, this problem is solved. Although it can be explained clearly in one sentence, it took ten years of effort.
Secondly, there is another engineering difficulty, because the explosive force of the atomic bomb is so strong that it can destroy the entire device in an instant. This requires that the time for the hydrogen bomb to ignite the helium-3 must be very, very short.
To put it simply, the atomic bomb ignites the hydrogen bomb, and the hydrogen bomb ignites the helium-3. The design is very good, but in practice it is extremely difficult. Often, the entire helium-3 layer is blown away by the atomic bomb before the hydrogen bomb ignites the helium-3.
Of course, it is also possible that only part of the helium-3 is ignited, but this result is still a failure for everyone.
In order to solve this problem, Professor Ding Yidong conducted detailed calculations. The inside of the nuclear bomb is simply a three-ring structure. In fact, it is very complicated. The purpose is to allow the helium-3 layer to be ignited as quickly as possible. Moreover, the deuterium-tritium layer
The thickness must be controlled within an appropriate range so that the deuterium-tritium layer and the helium-3 layer come into contact within the first moment of the explosion.
They designed an iron sheet paper that is only 20 nanometers thick to isolate the deuterium and tritium layer from the helium-3 layer. As long as this layer of iron sheet paper is punctured by force after the atomic bomb explodes, the helium-3 can quickly
It enters the deuterium and tritium layer and is ignited. Of course, there must be an anti-vibration design inside, and the iron paper will not be broken due to ordinary vibrations.
But in this way, the engineering difficulty is very high. First, the quality of the deuterium-tritium layer must be strictly controlled, preferably at the microgram level. Second, during the production process, the pressure of the helium-3 layer is slightly higher than that of the deuterium-tritium layer.
The tritium layer should be a little bigger, but not too big. Otherwise, once the iron paper is broken, everything will be mixed together, causing the experiment to fail.
Therefore, Professor Ding Yidong was very nervous. He only had one chance, and if he failed, he would never have another chance. He wanted to go up to help, but he also knew that going up would definitely be a disservice, so he could only wait helplessly at the back.
.
The same goes for several other people. They have done a lot of work, but they can only watch the last step. The same machine, different people do it, and the final result will definitely be different, just like the same factory, different shifts.
The products made by workers have different yields, and there are definitely some good ones and some bad ones.
There is a hierarchy of knowledge and expertise, so they can only believe in Li Wu unconditionally.
Li Wuze didn't have so many thoughts. He was now in a state of no joy and no worries, just focusing on what was in front of him. His hands began to operate, and each piece of work was like a computer program, without any mistakes, and was completed smoothly.
.
Most of the molds have already been produced in the factory, and the last thing he has to do is assemble them.
He controlled the electronic arm, first took out the atomic bomb from the black box, and carefully placed it in a fixed position. Of course, the shell of the atomic bomb had long been peeled off, leaving only a lead shell wrapped around it. The enriched uranium
The half-life is very long, and the radiation hazard is not very great. A layer of lead shell can basically block it, so no one is afraid of it.
One of the two soldiers was Zhao Yao from the special forces. This fat black man failed to attend the party and was assigned to perform this mission instead. He must be a little unhappy. But now, he dare not say anything and is nervous.
It's amazing, there are really bullets in his shot. If these scientists do anything, they will definitely shoot them.
What he advocates in the military is strength and passion, and he is very fond of the latest weapons and equipment. He has to rush to the first test every time, and he can recite the parameters of any firearms and artillery shells one by one. However, he sees that
When it comes to nuclear weapons, the most ferocious weapons in human history, there is still a strange sense of tension.
"We've finally seen the atomic bomb. We've also seen the hydrogen bomb and the more powerful helium-3 nuclear weapon." Zhao Yao suddenly felt that this trip was quite worthwhile.
As the procedures progressed, the robotic arm operated again and took out some solid compounds glowing with blue light. These are lithium deuteride and lithium tritide, the main materials of hydrogen bombs. The hydrogen bombs of current technology all use solid compounds.
Let’s use liquid hydrogen again.
Historically, the Americans successfully trial-produced the first hydrogen bomb in 1952, using liquid deuterium and tritium as thermonuclear materials. This put a big burden on the hydrogen bomb. To keep deuterium and tritium in a liquid state, a
A complex refrigeration system was installed, so that the first hydrogen bomb weighed 65 tons, which could be loaded on a train car.
This loses its practical significance. People call this type of hydrogen bomb using liquid deuterium and tritium as thermonuclear fuel a wet hydrogen bomb.
Later, scientists discovered that lithium-6, the isotope of the lithium element, is an excellent thermonuclear material. If lithium-6 deuteride and lithium-6 tritide are used as hydrogen bomb materials, not only can thermonuclear reactions be achieved, but also the
The heavy refrigeration system was removed, and the size of the hydrogen bomb was greatly reduced, achieving miniaturization.
Hydrogen bombs containing a mixture of lithium deuteride and lithium tritide are called dry hydrogen bombs.
Now, what Li Wu wants to make is a dry hydrogen bomb. The steps here are very critical. According to the design requirements, the materials are all quantitative. Of course, the higher the accuracy, the better. It is best to be accurate to 0.1 micrograms, which is one
To the extent of one millionth of a gram.
The best electronic scales now can barely reach this level. It is too difficult to achieve this accuracy. No matter how hard the average person works, they can only achieve the milligram level (1 gram = 1000 mg = 1000000
Micrograms), no matter how much my hands shake, it fluctuates around tens of milligrams, but Li Wu is different.
His hand is so stable that it is possible to achieve microgram accuracy. It is just a matter of time and patience. The robotic arm keeps moving and uses an extremely fine needle to extract the last few micrograms, but at this time, there is no
The manpower became more flexible. Li Wu immediately went into battle and began to manually extract.
He is constantly trying to enter a mysterious state. This state has often appeared before and is the pinnacle of experience and luck. Sometimes when the state is up, it can be completed in one fell swoop.
This may be a kind of practice that makes perfect, or it may be a personal talent. In short, it is difficult to explain clearly. Sometimes when I go to the vegetable market to buy vegetables, the pork seller can accurately cut the mass of a piece of meat without relying on an electronic scale, and the accuracy is accurate to the gram.
Li Wu thought that he might also have this kind of talent, but he was obviously countless times more powerful than the meat seller, and he could be accurate to micrograms.
