Magus Tech Chapter 1024: Early success and subsequent manufacturing

Eden, the main lab.

Li Cha walked in, sat in front of the circular experimental table, and glanced at a simple calendar on the table.

The so-called simple calendar is a scroll, which is divided into twelve large grids from top to bottom, representing twelve months in a year. There are almost 30 small cells in the large cell of each month, which contain different numbers such as one, two, three, four, five, etc., representing each specific day in each month.

At this time, more than half of the small grids on the scroll have been circled with a quill pen, which means that the date has passed.

Under normal circumstances, this is drawn by him in his spare time. Occasionally, Pandora will draw a few strokes with great interest.

You can clearly see the difference between the circles on the scroll: most of the circles are very standard, this is drawn by him; a few circles are very standard, as if drawn with a compass, this is drawn by Pandora, since Pandora studied deeply After mathematics, he showed an amazing talent for drawing images, and drawing by hand can almost reach the precision of drawing with tools. In addition, there is a lone circle that is flat, which is the handwriting of the old lich.

At this moment, he saw that the latest circle had been drawn to the end of the eighth large grid. But that circle is different from all the previous circles, it can't even be called a circle, because it is square.

Fang?

Li Cha looked at it, and couldn't help raising his eyebrows. A thought flashed through: This square pattern was definitely not drawn by him, and Pandora is also impossible, because the twists and turns are not standard at all. In this case, only Old Lich Ah Fu is the only one. It seems that the other party has been a little busy recently.

It's a little free.

The thought disappeared in a flash, and Li Cha didn't think much after confirming that it was the old man Lich, he just kept the date in his heart.

September 1st.

"Today is September 1st, the first day of the cold moon, and the beginning of autumn." After confirming the date, Li Cha said silently in his heart, with some emotion.

If memory serves me correctly, the nuclear weapons research and manufacturing program started in the autumn of last year.

To be precise, it was the frost moon of October last autumn.

At that time, Joseph from the Teresa branch of the Truth Society met him and gave him the crystal ball used for the Truth Society’s communication. It was during the meeting that he felt the erosive energy on the other person's body, which was later confirmed to be nuclear radiation residue, and he gradually found the source of the nuclear radiation in the uranium mine outside the small town of Shambhala.

Then acquired mines, built equipment, extensively mined, refined and purified, step by step to the present.

This long process took almost eleven months, almost a year.

The nearly one-year cost is completely worth it at present, because he has obtained a sufficient amount of weapon-grade nuclear material uranium-235, and completed the most critical step in the nuclear weapon research and manufacturing plan.

This is not an exaggeration. The acquisition of raw materials is extremely important in the manufacture of nuclear weapons, and it is also the most difficult. As long as this step is completed, the subsequent manufacturing process is extremely easy.

So far, his plan can actually be declared successful in advance, because under the premise of having enough nuclear materials, he can produce a nuclear explosion if he piles up the nuclear materials. This is the principle of the first generation of nuclear weapons .

The principle of the first generation of nuclear weapons is extremely simple. You only need to clarify three terms: continuous nuclear chain reaction, critical mass, and mass-energy equation.

Generally speaking, in the real world, heavy elements such as uranium and plutonium will undergo spontaneous fission due to radioactive decay, and nuclear reactions will also be triggered by foreign neutrons. They are called "fissionable substances".

These "fissionable substances" will release part of their own free neutrons in the process of spontaneous fission. The half-life of a free neutron is about 15 minutes, which means that after 15 minutes, it will decay into protons and beta particles.

However, in some special cases, free neutrons can hit other atoms before the half-life is reached, triggering nuclear fission of the remaining atoms, and then releasing more free neutrons. If these more free neutrons can hit the atom again, it will further produce nuclear fission.

When there are enough nuclear materials in a narrow space, once nuclear fission occurs, it will continue to proceed, forming a continuous nuclear chain reaction.

The amount of nuclear material that can sustain continuous nuclear fission is called the critical mass.

The critical mass is very important. Once the nuclear material reaches the critical mass, as long as one atom in the nuclear material undergoes nuclear fission and releases a neutron, or an external neutron source gives a neutron, a nuclear explosion can be produced .

In a nuclear explosion, a large number of atoms are broken, and the mass is damaged. The damaged mass will be converted into shocking energy and released. c2, just the loss of one kilogram of matter can release energy of (more than 8 billion billion) joules, which is equivalent to the detonation of 20 million tons of TNT explosives.

In a word, the principle of the first generation of nuclear weapons, that is, the atomic bomb, is to let the nuclear material reach a critical state and produce a continuous nuclear chain reaction. Based on the mass-energy equation, the lost mass is converted into terrifying energy and released, resulting in destructive Effect.

Because of this, he said that the nuclear weapons research and manufacturing program can already be declared successful in advance. As long as he wants, he can create a nuclear explosion at any time by accumulating nuclear materials.

However, he was unwilling to do so.

The principle of the first-generation nuclear weapons is very simple, but it is still a little bit difficult to actually make them.

The key point is that nuclear materials cannot be piled up casually to cause a nuclear explosion. Because the utilization rate of nuclear materials is extremely low, the final result may be that only one percent or even less than one thousandth of the atoms in all nuclear materials successfully undergo fission and release destructive energy, and the rest of the nuclear materials will be bombed. Fly, become radiation dust and float into the air.

To put it simply ~IndoMTL.com~ using the most direct and brutal way to trigger a nuclear explosion is easy, but it is a huge waste of nuclear materials.

Waste is shameful, waste makes him feel bad.

It took him almost a year to obtain a sufficient amount of nuclear materials. He wanted to make the best use of them and try to squeeze out all the value of these nuclear materials. He was definitely not satisfied with just listening to the sound.

So, in order to achieve his goal, he has to do something next. Specifically, it is to let the nuclear materials in hand reach the critical mass in a better way through special nuclear devices, and produce nuclear explosions and release energy with a higher utilization rate.

And to do this, it is necessary to use some knowledge that is not common.

After all, not everyone knows how the real atomic bomb is made, and even if they know, they don't think about it every day and talk about it.

"I'm going to that place again." Li Cha thought softly to himself.
