This has its own small kingdom, so it is natural to do a lot of it, and many experiments that I didn't dare to do before are now ready to do it!

In the future, many experimental equipment and devices that were previously restricted in China and were afraid to be carried out are quietly being carried out here.

In a relatively remote part of the scientific research area, an experimental building the size of ten basketball courts covers an area, and the roof of the building is all green optical panels like circuit boards.

The trees around this place are not like other places, they are tall and dense, and all trees above a certain height have been cut down!

Moreover, it is also covered with the Yuan Force magic array depicted by Liu Qingquan layer by layer, and the energy fluctuations of the magic circle everywhere are extremely obvious.

Here is the team leader Liu Qingquan, Level 3 scientists Jiang Zhipeng, Mo Qingming and the genius Chinese scientist Bruce Lee from overseas to participate, more than 200 Level 2 scientists, 600 Level 1 scientists, plus 200 top architectural engineers, such a luxurious and huge scientific research team to design and complete!

This is the laboratory used by Qingquan Technology to study nuclear fusion!

Yes, Qingquan Technology has directly bypassed the research process of nuclear fission and directly started nuclear fusion research!

Nuclear fusion, also known as nuclear fusion, refers to a form of nuclear reaction in which atoms with small masses, such as deuterium and tritium, under certain conditions (such as ultra-high temperature and high pressure), polymerize with each other's nuclei to produce neutrons and helium-4, accompanied by a huge energy release.

The nucleus contains a huge amount of energy, and according to the mass-energy equation E=mc^2, the static mass change (mass loss) of the nucleus causes the release of energy.

If it is changed from a heavy nucleus to a light nucleus, it is called nuclear fission, such as an atomic bomb explosion; If it is changed from a lighter nucleus to a heavier nucleus, it is called nuclear fusion, such as the energy source for stars to continue to shine and heat.

Compared with nuclear fission, nuclear fusion has much less environmental problems such as radioactive contamination, such as the nuclear fusion reaction of deuterium and tritium, and its raw materials can be taken directly from seawater, and the source is almost inexhaustible, so it is a more ideal way to obtain energy.

In addition, for the people of Qingquan Technology, it is very simple to obtain the raw materials for nuclear fusion, which can be extracted from seawater, but the heavy nuclear materials needed for nuclear fission, such as uranium or plutonium, cannot be bought with money, and the purchase of these materials will definitely be discovered by other countries.

Therefore, everyone at Qingquan Technology unanimously decided to go directly to nuclear fusion research!

Nuclear fusion has great advantages over nuclear fission, first of all, the acquisition of the raw materials mentioned above is more simple and easy to obtain, the world's reserves are very amazing, and there is a large amount of He3 on the moon; Secondly, the energy released by nuclear fusion is much larger than that released by nuclear fission, and the reaction energy release effect is extremely high. The product is non-polluting, non-radioactive and many other advantages!

If nuclear fusion has so many advantages, why is there not a single truly operational fusion reactor in the world? You must know that there are hundreds of nuclear fission power stations in the world.

Nuclear fusion has its own natural limitations, and this limitation has plagued the scientific community for more than half a century!

The reaction conditions required for nuclear fission are very weak, and natural uranium ore can decay under natural conditions at room temperature. However, compared with the nuclear fission process, the most troublesome reaction condition for nuclear fusion is that it requires an instantaneous high temperature of hundreds of millions of degrees to cause a nuclear fusion reaction, and such a high temperature cannot be achieved by traditional heating methods.

When mankind developed the hydrogen bomb, a solution to this problem was given: detonate the hydrogen bomb with a nuclear bomb! That is, the temperature of the nuclear fusion reaction is obtained by the detonation of the nuclear bomb, which causes the nuclear fusion to explode the hydrogen bomb, so there is a small nuclear bomb inside the hydrogen bomb.

But this kind of nuclear fusion is uncontrollable, for human beings can only be used to destroy, and there is no other use, really want to achieve the same as nuclear fission, the whole process of nuclear fusion control, but also need to solve two major difficulties!

First, how do you heat the raw materials for nuclear fusion to such a high temperature? Nuclear fusion requires temperatures of up to hundreds of millions of degrees!

Second, what will be used to heat the raw material for nuclear fusion to such a high temperature? The temperature of hundreds of millions of degrees is comparable to the temperature of the sun, and it can melt everything!

The research of nuclear fusion by human scientists began in the 50s of the last world, and the first time it was definitely the hydrogen bomb, and then how to achieve controlled nuclear fusion, because controlled nuclear fusion is of great significance to human beings, and the hope of solving the human energy problem lies in this.

For the two problems encountered in controllable nuclear fusion, there are currently some research results, Qingquan Science and Technology people are naturally the predecessors planted trees and the descendants take advantage of the shade, closely following them, and Liu Qingquan also actively refers to the early research results of nuclear fusion in the Alfa person, and the two are integrated with each other!

For the first problem, how to heat the raw materials of nuclear fusion to hundreds of millions of degrees, this Qingquan science and technology people still refer to the research ideas of the earth target scientists, the method of heating the alpha is too out of the current level of science and technology, and it is impossible to learn at present!

As for how to heat, since the 60s of the last century, the invention of lasers has opened up ideas for the question of how to heat matter to extremely high energies.

It was the Soviet experts who first considered using lasers to heat the raw materials for nuclear fusion, because the method is energy-intensive and does not need to come into contact with the heated substance, which is simply similar to focusing the sun and igniting wood chips.

However, the energy of a single laser is too low, so in order to solve such a problem, the energy of multiple lasers needs to be focused on the same point.

This problem seems simple, but in fact it is very difficult, because it is necessary to ensure that in a short heating time, all directions of the heated object are heated evenly, and the ball collapses uniformly, which is simply understood as imagining the heated substance as a football, if you want to squeeze the air inside the football, the best way is to force it together from all sides to compress its volume. If you push the force from only two directions, the ball will deform, and the effect of the air inside the ball being squeezed will be greatly reduced.

This requires not only the extremely precise control of the direction of each laser, but also the strict control of the energy of each laser in this extremely short period of time, and the United States is currently making the fastest research progress in this field, and its "National Ignition Device" is currently able to focus 192 lasers on the same point.

The same is true for the nuclear fusion laboratory of Qingquan Technology, which is built with reference to the U.S. National Ignition Facility, which can focus 365 laser beams on the same point and instantly produce hundreds of millions of degrees of high temperature, which is enough to ignite the materials of nuclear fusion.

Moreover, compared to the U.S. national ignition device, which can only conduct an ignition experiment every few hours, this ignition device of Qingquan Technology can achieve 10 ignitions per second and release 10 pulses!

The ignition device of Qingquan Technology first enhances the external laser by 10,000 times, then splits a laser into 2 lasers, and then splits the 2 lasers into 4 beams, so it finally splits into 365 beams step by step, and continuously enhances the beam in the process of splitting, and its total energy increases to 5000 trillion times the energy just started, and finally focuses on a deuterium-tritium nuclear fusion fuel with a diameter of 3 mm, which can produce a high temperature of more than 100 million degrees and a pressure of more than 100 billion atmospheres. And then enough to trigger nuclear fusion!

Some people may ask, how much energy does it take to ignite it?

The photons of the laser are all directional, unlike the general light source, the photons are divergent, you think the sun shines on the earth, it will not burn the paper, but focus the light, then at a point, the energy will be greater, you can burn the paper, the principle is the same.

Laser energy is highly concentrated, but the energy contained in it is not necessarily very large, and the energy consumption is not too terrifying!

Well, the first problem has been solved, we rely on laser technology to create the conditions needed for nuclear fusion, and can ignite nuclear fusion fuel, so what device is used to hold this nuclear fusion reaction of up to hundreds of millions of degrees?

At present, geoscientists have proposed a variety of methods to control nuclear fusion, including ultrasonic nuclear fusion control method, laser confinement control method, inertial confinement control method, magnetic confinement control method and so on.

Among them, the most feasible is the magnetic confinement control method, the development of the "superconducting tokamak" device is to achieve the ability to store hundreds of millions of degrees of substances in it, the specific principle is very simple, high school physics textbooks have mentioned, it is to confine these substances in a closed ring to make them rotate at high speed, to fix them in a confined space, so as to achieve the disguised bloom.

It seems that the two major difficulties of nuclear fusion have been solved by the earthlings a long time ago, but there is a more serious problem at present, that is, there is no way to combine these two solutions for the two difficult points respectively!

That is, at the current level of the earth, it can only ignite nuclear fusion fuel or use "superconducting tokamaks" to install it, but it is very difficult to concentrate hundreds of lasers on such a small point!

The fusion substance needs to be stationary at the specified target position to wait for heating and ignition, and the superconducting tokamak device belongs to the magnetic confinement process, if the fusion material is stationary, it cannot be confined in a designated confined space by the corresponding Lorentz force in the magnetic field.

Therefore, although scientists on Earth have solved the two major problems of nuclear fusion, they still cannot achieve controlled nuclear fusion, and these two solutions can only find a way to solve the other problem when they have a great advantage in solving one problem.

For the second problem, the people of Qingquan Technology naturally want to learn from the Alfa person, what method will the Alfa use to control the nuclear fusion at a temperature of hundreds of millions? (To be continued.) )
