Magus Tech

Richard appears at the magical proving ground at the bottom of the pit in the Garden of Eden.

This is already the seventh day after the start of nuclear weapons production.

After a week, he completed the first four important processes for the production of nuclear weapons, as well as many tedious processes behind, and pushed the progress to 60%, with 40% of the progress remaining, waiting to be completed .

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 loads, neutron sources, and shells.

The high-energy explosives are the energy source for pushing and compressing the reflective layer and the nuclear charge.In other words, it is the high explosive, which slammed the metal core uranium components that were manufactured before and reached a supercritical state, and then triggered 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 be exploded.

But 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 can be exploded, but also meet the standards.

What does it mean to meet the standard?

Generally speaking, implosion-type high-explosives are installed in the shape of an ellipse with dozens or hundreds of them arranged in an oval shape, which looks like a pearl necklace.

In order to allow the metal uranium component to be squeezed to the greatest extent, it must be ensured that each "pearl (explosive block)" on this "pearl necklace" can be detonated together, and then the impact force of the explosion passes 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 subtle, that is one millionth of a second.

Because the speed of explosive explosion is very fast.

The low-grade explosives such as mercuric acid can reach a detonation rate of several kilometers per second, while the high-grade explosives such as "Horsogin", "Tai'an" and "Oktojin" can reach a detonation rate Ten thousand meters per second.

"CL-20 (hexanitrohexaazaisowurtzitane)", "DNAF (4,4'-dinitro-3,3'-azofuran)) and other monsters, the detonation speed directly exceeds ten thousand per second At the rice mark, further explosives such as pentazole anion salts and metal hydrogen exist ①.

Even if the blasting speed of the explosive is controlled at eight kilometers per second, the gap of one microsecond is eight millimeters, which is close to one centimeter.

This distance is okay to put elsewhere, but in nuclear weapons, it is fatal, so it must be detonated at the same time.

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

You should know that the spread of explosion and the release of power are extended from a point to a ball.Even if it can really ensure that all explosives are detonated at the same time, it also uses countless "spherical pressure surfaces" to squeeze the metal uranium components.

It is like using countless blown basketballs to squeeze a huge dough, it is impossible to ensure that the surface of the dough does not appear depressed.

If there is a depression, there is a defect.

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

According to the design requirements of implosion-type atomic bombs, the spherical pressure must be turned into a plane pressure, and the metal uranium component should be squeezed with a plane, so that the metal uranium component can be squeezed tightly enough to reach a higher supercritical state and greater Use of hard-won nuclear materials in quantities.

But how does a sphere become a flat surface?

Explosives are not obedient and will not be spread by outsiders as long as they spread. It will only faithfully release its power according to physical rules.

Between two points, the line segment is the shortest.

As long as the distortion of space is not considered within the framework of classical mechanics, then according to the law of the shortest path, the power is transmitted from a point to the surroundings, and the final result is a sphere.

Always a ball.

ball!

In order to solve this ball, there is only one way, that is to use compound explosive blocks.

Yes, compound explosive block.

The compound explosive block, as the name suggests, is composed of a variety of different explosives.

As everyone knows, different types of explosives and different detonation speeds, then it is possible to design explosive blocks in this way: the middle is a low-speed explosive, the outside is a medium-speed explosive, and the outermost is a high-speed explosive.

When explosives detonate, low-speed explosives will spread slowly, followed by medium-speed explosives, and high-speed explosives 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, certain optimization can also be carried out.

For example, only two explosives with different detonation speeds are needed. In each explosion zone, the ratio of low-speed explosives to high-speed explosives can be adjusted to control the propagation speed of explosives.

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

The peripheral explosive zone, the produced explosive column, can be filled with one-sixth of the low-speed explosive and the lower five-sixth of the low-speed explosive, so that the speed of the entire explosive column will be balanced to about 2.7, which is different from the central explosive zone, and finally produced 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 whose ratio of explosives can meet the requirements.

Standing in the magic research field, Richard took out the explosive columns from the iron ring of space and began to arrange them carefully around a fist-sized test target.

The arrangement was completed and detonated decisively.

"Boom!"

In the magical proving ground, explosions continued to sound, and Richard continued to test.

It has to be said that in order to find the most suitable value for nuclear weapons and explosives, very tedious testing is required.Moreover, every test requires no error at all.

Because at the high detonation speed of explosives, every error will be amplified by thousands of times, resulting in a shortfall.

Fortunately, with the guidance of mathematics, you can eliminate more than 99% of the wrong options in advance. You only need to repeatedly test those that are calculated correctly and find the optimal solution.

"Boom!"

Time is passing.

...

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

In three days, Richard conducted dozens of explosion tests and hundreds of explosion tests at the magical proving ground, finally solved the problem of explosives, determined what kind of compound explosives are most suitable, and produced enough quantities. Come.

In other words, in three days, a big step towards the complete manufacture of nuclear weapons.
