Magus Tech (Technological Wizard)

Richard appeared at the spell testing ground at the bottom of the Tiankeng in the Garden of Eden.

This is the seventh day since nuclear weapons production began.

After a week, he completed the first four important processes of nuclear weapon production, as well as many subsequent tedious processes, and advanced the progress to 60%, leaving 40% of the progress, waiting to be completed .

But now, what he has to do is the more important step in the 40% progress - the experiment of nuclear weapons detonating explosives.

As mentioned before, nuclear weapons such as atomic bombs are composed of detonation control systems, high-energy explosives, reflective layers, nuclear components containing nuclear charges, neutron sources, and shell casings.

The high-energy explosive is the energy source for pushing and compressing the reflective layer and nuclear charge. In other words, it is a high explosive, which suddenly backlogs the previously manufactured "Crystal Heart" metal uranium components, reaches a supercritical state, and then triggers a nuclear explosion.

If it is a gun-type atomic bomb, the setting of high-energy explosives is extremely simple, as long as it can explode.

However, in order to avoid waste and save hard-won uranium-235 nuclear raw materials, the atomic bomb made by Richard is not a gun type, but an implosion type.

This requires that high explosives not only be able to explode, but must also explode in accordance with the standards.

What do you mean by conforming to the standard?

Generally speaking, the implosion-type high explosives are arranged in an oval shape of dozens or hundreds of pieces and installed inside the nuclear weapon, which looks like a pearl necklace.

In order to allow the metal uranium components to be squeezed to the greatest extent, it is necessary to ensure that each "pearl (explosive block)" on this "pearl necklace" can be detonated together, and then the impact force of the explosion is passed through the rhenium-tungsten alloy. The conduction of the component acts on the metal uranium component at the same instant.

The most important thing is at the same time.

must be at the same time.

The error cannot exceed one microsecond, which is one millionth of a second.

Because the speed of explosive explosion is very fast.

Low-grade explosives like mercury fulminate have a detonation velocity of thousands of meters per second, while high-grade explosives such as "Hessokin", "Tai'an", and "Octokin" have a detonation velocity close to that of every second. 10,000 meters per second.

"CL-20 (hexanitrohexaazaisowurtzitane)", "DNAF (4,

4'-dinitro-3,3'-azofurazan)" and other monsters, the detonation speed directly exceeds the mark of 10,000 meters per second, and there are also ultimate explosives such as pentazolium anion salt and metal hydrogen Existence①.

Even if the detonation velocity of the explosive is controlled at 8,000 meters per second, the gap of one microsecond is still eight millimeters, which is close to one centimeter.

This distance is nothing to put elsewhere, but in nuclear weapons, it is fatal, so they must be detonated at the same time.

And just detonating the explosives at the same time is just the beginning.

You must know that the propagation of the explosion and the release of its power extend from a point to a ball. Even if it is really possible to ensure that all explosives detonate at the same time, countless "spherical pressure surfaces" are used to squeeze the metal uranium components.

Just like using countless blown basketballs to squeeze a huge dough, it is impossible to guarantee that there will be no depressions on the surface of the dough.

Where there is a dent, there is a defect.

Therefore, even if the detonation time error of all explosives is strictly controlled within one microsecond, it still cannot meet the design requirements of an implosion atomic bomb.

According to the design requirements of the implosion-type atomic bomb, it is necessary to change the spherical pressure into a plane pressure, and use the plane to squeeze the metal uranium components, so that the metal uranium components can be squeezed tightly enough to achieve a higher supercritical state. Quantities of hard-won nuclear material are utilized.

But how does a sphere become a plane?

Explosives are not obedient, and will not spread as outsiders say. It will only faithfully release its power according to the laws of physics.

The shortest line segment is between two points.

As long as the distortion of space is not considered under the framework of classical mechanics, then according to the law of the shortest path, power is transmitted from one point to the surroundings, and finally a spherical surface is formed.

Always a ball.

ball!

In order to deal with this ball, there is only one way, and that is to use a block of composite explosives.

Yes, composite explosive blocks.

Composite explosive blocks, as the name suggests, are composed of a variety of different explosives.

As we all know, different types of explosives have different detonation velocities, so the explosive block can be designed like this: the middle is a low-velocity explosive, the outside is a medium-velocity explosive, and the outermost is a high-velocity explosive.

When explosives are detonated, low-velocity explosives will travel slowly, medium-velocity explosives next, and high-velocity explosives very quickly. In this way, the pressure surface, which is originally a spherical diffusion, will have a certain degree of depression, and a plane will be formed in a certain direction.

In actual operation, some optimization can also be carried out.

For example, only two kinds of explosives with different detonation velocities are needed, and the propagation speed of the explosives can be controlled by adjusting the ratio of low-velocity explosives and high-velocity explosives in each explosion zone.

To give an example: For example, the detonation velocity of high-velocity explosives is 3, and the detonation velocity of low-velocity explosives is 1. In the middle explosive section, make an explosive column, fill the upper third with low-velocity explosives, and the lower two-thirds with high-speed explosives, so that the velocity of the entire explosive column will be balanced to 2.

As for the peripheral explosives partition, the explosive column made can be filled with low-velocity explosives in the upper one-sixth, and low-velocity explosives in the lower five-sixths, so that the velocity of the entire explosive column will be balanced to about 2.7, which is different from the central explosives partition, and finally produces pressure plane.

What Richard is doing now is to use different explosives and adjust different ratios to test which types of explosives are the most stable and which ratios can meet the requirements.

Standing at the spell research field, Li Cha took out explosive columns one by one from the space iron ring, and carefully arranged them around a fist-sized test target.

After the arrangement is complete, detonate decisively.

"Boom boom boom!"

In the spell testing field, the sound of explosions kept ringing, and Li Cha continued to test.

It has to be said that in order to find the most suitable value for detonating explosives for nuclear weapons, very tedious tests are required. Moreover, every test requires no slightest error.

Because under the high detonation velocity of explosives, every error will be magnified hundreds of times, resulting in a failure.

Fortunately, with the guidance of mathematics, more than 99% of the wrong options can be eliminated in advance, and it is only necessary to repeatedly test the correct calculations to find the optimal solution.

"Boom boom boom!"

Time keeps ticking.

...

In a blink of an eye, another three days passed.

In three days, Li Cha conducted dozens or hundreds of explosion tests in the spell testing ground, and finally solved the problem of detonating explosives, determined what kind of composite detonating explosives is the most suitable, and produced enough quantities Come.

In other words, within three days, a big step has been made towards the successful manufacture of nuclear weapons.
