Chapter 648 Yu Min's Configuration Is Released! (Part 2)

“.”

At this moment.

Dayu, who had already entered the state, did not notice Xu Yun's loss of composure, but spoke to himself:

“Comrade Xu Yun, according to the information we have learned, in the T-U configuration, the primary generated X-rays will quickly fill the radiation channel.”

“In this case, the radiation channel will form a black body radiation cavity with a nearly uniform temperature, and the low atomic number material in the radiation channel will be heated by the X-rays into a high-temperature plasma.”

“But the light element material has a very small cross-section with X-rays, and is almost completely transparent, making it difficult to interact with X-rays.”

“Our light nucleus group was stuck in this part for a long time before, and we thought of nearly ten ways, but none of them could solve this problem.”

“But now let’s see if we change the convergence angle and consider quantum tunneling, which seems to be feasible.”

“No, I have to calculate!”

After that.

Dayu picked up his little notebook again and began to write as if no one was around.

Xu Yun opposite him was in a daze for a long time before slowly coming back to his senses.

Goddess Shunzi, what did I hear?

As we all know.

In 2023, when Xu Yun traveled through time, there has always been a lot of controversy about hydrogen bombs.

You can say that.

Except for the ignition method, all other information about hydrogen bombs is just speculation. Or it can be said that there is no real evidence to prove it.

The hydrogen bomb-related information that everyone can find is the papers written by people who have participated in the development of hydrogen bombs. The most recent one was in 1971.

The structure is the focus of debate among all parties.

For example, many people believe that hydrogen bombs do not actually exist in the Min configuration. The rabbits and the other side of the sea are actually T-U configurations.

In order to prove this statement, there is even a so-called popular science:

[The Yu Min configuration circulated on the Internet is powerful, but it cannot reduce the maintenance cost of hydrogen bombs and extend their service life. The principles of the hydrogen bombs of the rabbits and the other side of the sea are basically the same, and the nuclear charge also uses lithium deuteride 6. Lithium deuteride 6 is a compound, and there is no so-called decay period. No matter what configuration, it cannot change its own physical and chemical properties, so there is no such thing as extending its life. 】

【In fact, the life of a hydrogen bomb mainly depends on its electronic, plastic, rubber and other aging parts, and the life of these parts mainly depends on their own materials and processing technology. The opposite side of the sea has a clear advantage in this regard. The average life of its thermonuclear warhead is close to 30 years, while other countries including China and Russia have an average of only about 15 years, which is far behind the opposite side of the sea. 】

This is actually the most disgusting and vicious type of popular science.

It is full of professional terms from beginning to end, which makes you sound mysterious and powerful, providing evidence for its "authority".

At the same time, more content sounds simple and clear, as if people can understand the so-called truth at a glance, which is extremely misleading.

But in fact.

This type of popular science ignores a very important and even core detail:

Gas-assisted explosion, that is, the detonation mechanism.

This is actually the lifeblood of the hydrogen bomb!

Students who have developed hydrogen bombs should all know it.

The logical structure of the hydrogen bomb is actually to install a small atomic bomb inside the reaction device, and the atomic bomb will release a lot of heat and neutrons after nuclear fission explosion.

Then lithium deuteride 6 quickly decomposes into deuterium and lithium, and lithium combines with neutrons to produce tritium.

Finally, tritium and deuterium undergo fusion reaction at extremely high temperature, and the hydrogen bomb explodes.

But if you really follow this method, you can't make a hydrogen bomb. The three next door are the best examples.

Because the most critical part of this step is not the generation of tritium and deuterium, but how lithium deuteride 6 decomposes into deuterium and lithium-this step requires gas boosting.

The primary gas boosting is to put high-pressure tritium gas in a small gas tank inside the nuclear warhead, and only when the nuclear warhead needs to be activated, it is manually introduced into the nuclear ball.

Under normal circumstances.

1.5 grams of tritium participates in the reaction, and can release neutrons that directly cause 120 grams of plutonium to fission in a typical small fission trigger made of 4.5 kilograms of plutonium, and the second generation of neutrons will cause 660 grams of plutonium to fission-this is the gas boosting of ordinary atomic bombs.

If you want fusion, it is also simple, just add more directly.

This step requires high-pressure tritium gas, and the half-life of tritium is 12.5 years.

That is, after 12.5 years, the tritium of the finished product is only half of the previous one, and the other half decays into helium-3, and a neutron inside will become a proton plus an electron and combine into protium.

In the end, it is half tritium, 25% deuterium and 25% protium.

The density of tritium is half, the reaction speed becomes 1/4, and half of the neutrons will be absorbed by protium and deuterium, and the neutron density becomes 1/2.

The final reaction speed and power will become less than 1/8, and it is very likely that there will be no explosion.

But if you don't inject tritium at ordinary times and inject it when you need it, the time and operation required will be very complicated-this is the origin of the saying that hydrogen bombs cannot be stored for a long time on the other side of the sea.

The larger configuration does not need this step directly, so it will be much simpler to maintain.

So seeing this, I think many people should understand.

That’s right, whether it’s the rabbits, the other side of the sea, or Russia’s hydrogen bombs, they all require lithium deuteride 6.

But the concept of this thing is only equivalent to the CPU. The difference between the greater than configuration and the T-U configuration is to assist the CPU in cooling.

For cooling, you can use air cooling or water cooling. Water cooling is divided into 240 and 360. There are too many things to say here.

Those so-called popular sciences point to the CPU of lithium deuteride 6 and say that whether it is 13490 or 12490, they all use Intel's processing framework-but who discusses the CPU?

What should be discussed is whether different cooling has a good pressure-heating effect on the same CPU?

Of course.

Although that kind of popular science is a typical concept substitution, it is indeed wrong to say that only rabbits have hydrogen bombs.

Nowadays, both the opposite side of the sea and the next door Russia have hydrogen bombs, but the tritium barrels are not fully equipped, and there are only two or three lids for 10 pots-except for the strategic bombers and submarines on duty.

Generally, the tritium barrels and neutron sources of atomic bombs that are not on duty are kept in warehouses all year round. The tritium barrels of the bomber units are actually fully equipped by whoever goes to the sky, and they are unloaded if they don’t go to the sky.

The saying that only the rabbits have hydrogen bombs is largely "attributed" to Professor Jin Canrong, who once joked in a lecture:

[China is the only country in the world that still has 30 usable hydrogen bombs].

The hydrogen bomb he mentioned should actually refer to the three-phase bomb, and it can be traced back to the news that the last two-phase bomb was destroyed across the sea.

Still using the graphics card as an example, the three-phase bomb is the 40 series graphics card, and the two-phase bomb is the 10 series graphics card.

Now the other side of the sea has thrown away its 10 series graphics card and replaced it with 4080. Although the performance is slightly different from our 4090, you obviously can't say that the other side of the sea doesn't use graphics cards anymore.

However, I guess this old man doesn't understand the difference between three-phase bombs and two-phase bombs. Just seeing the other side of the sea say "We threw away the 10 graphics card", he thought they would no longer use graphics cards, so the rumor spread more and more.

So it is unnecessary for those who are engaged in finance and politics to mix too much with scientific and technological knowledge, especially those influential public figures. They are so happy that they talk big, but the technology circle is inexplicably hated.

In short.

From the military field, the existence of the greater than configuration is not a question. The controversy mainly lies in the specific difference between it and the T-U configuration across the sea.

Some people think that the special feature of the greater than configuration is that the U238 neutron reflection layer of the secondary bomb is removed.

Some people think that the essential difference between the T-U configuration and the greater than configuration is actually how to guide the light pressure source generated by primary fission.

Others believe that the special feature of Dayu is that he designed a multi-layer nest structure that can give birth to seven gourd babies at a time.

All kinds of speculations have their own reasons, which have always been a hot topic in military forums.

But now, judging from Dayu's reaction.

If nothing unexpected happens, Dayu's idea should be X-ray laser nuclear fusion.

As we all know.

The radiation energy of the fission primary is concentrated in the X-ray band, so all hydrogen bombs must be designed around the X-ray radiation implosion.

And as of now, heavy element push layer ablation is the only way to use X-rays.

According to the last paper of Taylor and his team, which was also the one that was made famous.

They expected that the X-rays generated by the primary would quickly fill the radiation channel, forming a blackbody radiation cavity with a nearly uniform temperature, and the low atomic number materials in the radiation channel would be heated by the X-rays into high-temperature plasma.

But Dayu's thinking took into account the gradient compression between the columnar secondary, and formed these gradients into a kind of potential barrier through the scenario of quantum tunneling.

This is really a genius idea.

Then Xu Yun sat quietly on the bed, quietly waiting for Dayu's calculation.

Da Yu and I are really strong.JPG.

This time, Da Yu took much longer to calculate than before. After more than an hour, he put down his pen hesitantly.

"Comrade Xu Yun."

Then Da Yu handed his calculation paper to Xu Yun and said to him:

"Do you think my idea is correct?"

Xu Yun originally wanted to say that he didn't understand a word about the structure of the hydrogen bomb, but thinking that the calculation paper in front of him was probably about the legendary thing, he couldn't help but take it and read it.

At the same time, Da Yu also took the initiative to introduce:

"Comrade Xu Yun, I calculated a pressure-time curve along the axis, and finally found that the foam plasma alone should not be able to guarantee a uniform X-ray radiation field in the cavity - that is, the diffuse reflection of X-rays by the inner wall is the more important mechanism for producing ablation effect."

"So I designed a special structure that can delay the secondary proximal ablation and use the tunneling effect at the same time. I call it an X-ray lens."

After that.

Dayu tapped the paper in front of Xu Yun with the end of his ballpoint pen and drew a circle:

"According to the design of our atomic bomb, the X-rays emitted from the primary are radial relative to the secondary. In order to make the secondary get as uniform X-ray radiation as possible, the X-rays need to be transformed into a convergent form."

"But X-rays themselves are very special, with extremely high photon energy. They can penetrate most materials almost without loss, and the refractive index is slightly less than 1."

"So if you want to make an X-ray lens, the lens shape should be close to a concave lens, and you can only use grazing incidence to achieve total reflection."

"Of course, this design will lose a considerable amount of X-rays, which is the reduction of the convergence angle I mentioned before, but with the assistance of the gradient of the tunneling effect, the remaining X-rays can achieve high-precision convergence."

Da's introduction was very concise. Even a layman like Xu Yun, who didn't know much about the structure of hydrogen bombs, showed some understanding on his face at this time.

I see

To put it bluntly, the idea of ​​"greater than" is actually just one sentence;

Materials with different ablation speeds and post-ablation recoil velocities were selected to balance the time difference between the distal and proximal ends.

Generally speaking, heavy elements have higher opacity to X-rays, that is, they are more able to absorb the energy of X-rays. This problem can be solved by using more light element materials at the proximal end of the secondary:

By replacing part of the ablation-push layer originally made of heavy elements with light element materials, the corresponding ablation rate is reduced, thereby achieving the purpose of secondary uniform compression.

This way.

when the device starts.

Hundreds of high-intensity laser beams will hit the deuterium-tritium ball at the center of the ball within 1 nanosecond, ionizing the surface of the ball and compressing the center of the ball to reach the conditions for the fusion reaction.

Suddenly.

Xu Yun then thought of the X-ray laser nuclear fusion project of later generations of rabbits. That project used X-ray lasers to heat a metal beryllium sphere to make it emit X-rays, and then radiate them uniformly to the fuel sphere.

Xu Yun then opened another page of calculation paper and prepared to continue reading.

But what surprised him was a little bit.

On the last page of the calculation paper, a mosaic filled the screen. When I spoke in front of me, I could only see the mouth shape but could not hear the content.

Another moment passed.

A bright red number 404 appeared on the calculation paper, and it kept floating in front of Xu Yun.

Seeing this situation, Xu Yun understood something instantly.

really.

The specific configuration of the hydrogen bomb will be an absolute secret in 2023. The third brother next door claims to have mastered fusion weapons, but in fact it is just an enhanced bomb.

If you are exposed to too much in this area, it is indeed easy to encounter a 404 situation.

Not to mention that I still have Uncle Tong, Sister Jiao, Elbow and the poisonous milk buff from the newspaper seller on my body, so I really should be cautious at this time.

So in the next time.

Xu Yun performed a pantomime in front of Yu Da, pretending to be enlightened while hearing nothing.

This situation reminded Xu Yun inexplicably of when he was in junior high school. This was how he dealt with the teacher when he was taking courses he didn't understand.

that's all.

After about half an hour, Xu Yun's voice sounded in his ears:

"Comrade Xu Yun, what do you think of my idea?"

After hearing this, Xu Yun thought for a moment and gave a thumbs up to Da Da:

"middle!"

Although I don’t understand what Yu Da said in the second half, judging from the content of the first half, Da Yu’s idea is obviously the legendary one.

Yu Min's configuration!

This is a plan that has been tested in actual combat, and Xu Yun can believe it without any hesitation.

Greater than configuration, that’s it.

This world!

Soon, Xu Yun realized another thing:

Although the larger configuration looks the same as the wall-mounted structure in history, it has been released more than two years and almost three years ahead of schedule.

In other words.

If all goes well, maybe there's a chance for a hydrogen bomb

Marrying with "Miss Qiu"?

Note:

I really can’t write more about the larger than the configuration, so this is the end. Keep writing, don’t talk about the book, I guess you won’t even see me.
