Into Unscientific

"."

At this moment.

Yu Yu, who had already entered the state, did not notice Xu Yun's gaffe, but kept talking to himself:

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

"In this case, the radiation channel will form an approximate blackbody radiation cavity with uniform temperature, and the low atomic number material in the radiation channel is heated by X-rays into high-temperature plasma."

"But the interaction cross section of light element materials with X-rays is extremely small, they are almost completely transparent, and it is difficult to interact with X-rays."

"Our light core team has been stuck in this part for a long time. We have thought of nearly ten ways, but none of them can solve this problem."

"But now it seems that if we change the convergence angle and consider quantum tunneling, this seems to be feasible."

"No, I have to do the math!"

Say it.

Yu Da then picked up his little notebook again and began to write as if no one else was watching.

Xu Yun, who was opposite him, was in a daze for a while, and then slowly came back to his senses.

Goddess Shunzi is on top, what the hell did I hear?

As everyone knows.

In 2023, when Xu Yun traveled back in time, weapons such as hydrogen bombs have always been controversial.

It can be said like this.

Except for the ignition method, all other information about the hydrogen bomb is just speculation or speculation without any solid evidence.

The information related to the hydrogen bomb that anyone can find is the kind of papers written by people who participated in the development of the hydrogen bomb. The most recent one was in 1971.

Among them, structure is the focus of debate among all parties.

For example, many people believe that the hydrogen bomb does not actually exist in a sensitive configuration at all, and that the rabbits and the other side of the sea are actually in the T-U configuration.

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

[Although the Yu Min configuration reported online is powerful, it cannot reduce the maintenance cost and extend the service life of the hydrogen bomb. The rabbits have basically the same principle as the hydrogen bomb across the sea, and the nuclear charge also uses lithium deuteride 6. Lithium deuteride is a compound that does not have a so-called decay period. No matter what configuration it is, it cannot change its physical and chemical properties, so there is no way to extend its lifespan. 】

[In fact, the lifespan of a hydrogen bomb mainly depends on its electronics, plastics, rubber and other parts that are prone to aging, and the lifespan of these parts mainly depends on their own materials and processing techniques. Haidian has an obvious advantage in this regard. The average thermonuclear warhead The lifespan is close to 30 years, while the average in other countries, including China and Damao, is only about 15 years, which is far from that across the sea. 】

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

It is filled with a lot of professional terms from beginning to end, making you sound unclear and providing evidence for its "authority".

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

But actually.

This kind of popular science ignores a very important, even core, detail:

Gas-assisted detonation is the detonation mechanism.

This is actually the lifeblood of the hydrogen bomb!

Students who have developed hydrogen bombs should all know this.

The logical structure of the hydrogen bomb is actually to install a small atomic bomb inside the reaction equipment. The atomic bomb will release a large amount 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 a fusion reaction at extremely high temperatures, and the hydrogen bomb explodes.

But if you really follow this method, you won't be able to 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 the use of gas-assisted explosion.

The primary gas-assisted explosion is to install high-pressure tritium gas in a small gas tank inside the nuclear warhead. Only when the nuclear warhead needs to be activated, is it manually introduced into the nuclear ball.

In general.

When 1.5 grams of tritium participates in the reaction, a typical small fission trigger made of 4.5 kilograms of plutonium can emit neutrons that directly fission 120 grams of plutonium. The second generation neutrons will fission 660 grams of plutonium - this is the gas of an ordinary atomic bomb. Assist explosion.

If you want fusion, it's easy, just increase the amount.

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

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

Finally, it is half tritium, 25% each of deuterium and protium.

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

In the end, the reaction speed and power will become less than 1/8, and it will probably not explode.

But if tritium is not injected at ordinary times and then injected when needed, the time and operation required will be very complicated-this is the origin of the statement that hydrogen bombs cannot be stored for a long time across the sea.

For larger configurations, this step is not needed, and maintenance will naturally be much simpler.

So after seeing this, many people must be able to understand.

That's right, whether it's the rabbits or the hydrogen bomb across the sea or Da Mao, lithium deuteride 6 is indeed used.

But the concept of this thing is only equivalent to the CPU. The difference between the larger configuration and the T-U configuration is to assist in the heat dissipation of the CPU.

For heat dissipation, you can use air cooling or water cooling. Water cooling is divided into 240 and 360. There is a lot to talk about here.

Those so-called science popularizations point to Lithium Deuteride 6, a CPU masterpiece, saying that both 13490 and 12490 use Intel's processing framework - but who is talking about CPU?

What should be discussed is obviously whether different heat dissipations have a good heating effect on the same CPU?

Of course.

Although that kind of science popularization is a typical concept of stealing and avoiding the important, it is indeed wrong to say that only rabbits have hydrogen bombs.

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

Under normal circumstances, tritium barrels that are not on duty and the neutron source of the atomic bomb will be kept in the warehouse all year round. In fact, the tritium barrels of the bomber force are filled by whoever goes to the sky, and they are unloaded if they are not in the sky.

The statement that only rabbits have hydrogen bombs is largely attributed to Professor Jin Canrong. He 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 a three-phase bomb, and further back it can be traced back to the news of the destruction of the last two-phase bomb across the sea.

Still using graphics cards as an example, three-phase bombs are 40 series graphics cards, and two-phase bombs are 10 series graphics cards.

Now Haidian has lost his 10 series graphics card and replaced it with a 4080. Although the performance is slightly different from our 4090, you obviously can't say that Haidian doesn't use a graphics card anymore.

Naihe guessed that this old man didn't understand the difference between three-phase bombs and two-phase bombs. Just when he saw the other side of the sea saying "We lost the 10 graphics cards", he thought they would never use graphics cards anymore, so the rumors became more and more popular. The spread spread.

Therefore, there is no need for those engaged in finance and politics to mix too much with scientific and technological knowledge, especially those influential public figures. They enjoy themselves by talking loudly, but they inexplicably attract hatred from the technology circle.

all in all.

The existence of the larger than configuration is not a question in the military field. 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 larger configuration is the removal of the U238 neutron reflection layer that removes the secondary bomb.

Some people believe that the essential difference between the T-U configuration and the larger configuration lies in how to guide the light pressure source generated by primary fission.

Others think that the special feature of Da Da is that it has designed a multi-layered nest-like structure that can give birth to seven gourd babies at a time.

All kinds of speculations have always been a hot topic in military forums.

But now judging from the reaction of greater than.

If nothing else, the big idea should be X-ray laser nuclear fusion.

As everyone knows.

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

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

Judging from the last paper written by Taylor and his wife that year, which was also the one that conferred the title of god.

What they expected was that the X-rays generated in the primary quickly filled the radiation channel, forming an approximate blackbody radiation cavity with uniform temperature, and the low atomic number materials in the radiation channel were heated by X-rays into high-temperature plasma.

But Yu's thinking takes into account the existence of gradient compression between columnar secondary levels, and these gradients form some 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 Yu Yu's calculations.

I am stronger than I am.JPG.

This time the calculation took much longer than before. More than an hour passed before he put down his pen with some hesitation.

"Comrade Xu Yun."

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

"Look at my train of thought, right?"

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

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

"Comrade Xu Yun, I calculated a pressure-time curve along the axis, and finally found that 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 more The primary mechanism producing the ablative effect.”

"So I designed a special structure that can delay the first ablation of the secondary proximal end and take advantage of the tunneling effect. I called it an X-ray lens."

Say it.

Yu Da used the end of his ballpoint pen to tap on the arithmetic paper in front of Xu Yun, and at the same time made a circle-drawing motion:

"According to the design drawings of our atomic bomb, the X-rays emitted from the primary are radial compared to the secondary. In order for the secondary to receive as uniform X-ray radiation as possible, the X-rays need to be transformed into a concentrated form."

"But X-rays themselves are very special. The photons have extremely high energy. They can penetrate most materials almost without loss, and the refractive index will be 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 if you want total reflection to occur, you can only use grazing incidence."

"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 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 404 situations.

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 Da Da said in the second half, judging from the content of the first half, Yu Da’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 much more about the larger than the configuration, so that’s the end here. Keep writing, don’t talk about the book, I guess you won’t even see me.
