Chapter 218 Chapter 215 Level 2 Civilization

However, the change from quantitative change to qualitative change has made humans truly feel how powerful the secondary civilization is.

Of course, scientific advancement is never achieved overnight.

The realization of heavy nuclear fusion by humans is also the accumulation of countless years and countless related technologies. The process of winning the crown of heavy nuclear fusion technology is also achieved step by step.

In the past eighty years, humans have continued to climb on the basis of helium nuclear fusion.

The first to be achieved was carbon fusion into neon.

Using high temperature and high pressure resistant materials as fusion furnaces, humans relied on materials copied from the crashed alien spacecraft on Callisto to withstand the high temperature environment of carbon fusion into neon.

However, when it comes to the stage of neon fusion into oxygen, this material can no longer withstand it, because the temperature required at this stage has exceeded 150 million degrees Celsius. And this temperature is obviously higher than the melting point of this metal.

Fortunately, humans did not foolishly use materials to resist it, but built equipment and high temperature and high pressure resistant components based on this material, and then constrained the fusion through super-strong magnetic fields.

With the participation of magnetic field, there is no need for materials and equipment to directly bear high temperature and high pressure.

This is easy to imagine, because the high temperature and high pressure required for fusion is not the high temperature and high pressure of the inner wall of the container, but the high temperature and high pressure of the fusion material itself.

Under the condition of magnetic field confinement, as long as the environment of the fusion material itself meets the fusion environment, nuclear fusion can occur.

Humans also took advantage of this point to complete the breakthrough of neon fusion into oxygen.

As for oxygen nuclear fusion, it is the fusion of oxygen nuclei into magnesium, and the lowest temperature is 200 million degrees Celsius with the pressure environment generated by the gravity of ten suns.

For humans, it is obviously easier to increase the temperature than the harsh pressure environment.

In addition to the previous experience of neon nuclear fusion, humans quickly thought of a solution, or the direction of progress.

That is to continue to strengthen the magnetic field, and then continue to increase the speed of the plasma jet to increase the temperature. When the temperature is increased, the pressure requirement will naturally decrease.

Finally, after 17 years of struggle, humans have made a breakthrough.

When breaking through magnesium nuclear fusion, it is actually when the relevant scientists of humans said that it would take another 30 years.

Students who have recited the periodic table know that after magnesium is aluminum, and after aluminum is silicon. Silicon fusion is the goal of human heavy nuclear fusion.

Creating pressure bearing pressure is more difficult than raising temperature bearing temperature, so human scientists decided to use the old method and old route to continue to increase the temperature and the speed of plasma flow.

Raising the temperature and the speed of plasma flow is simple to say, but it is actually very difficult.

As we all know, nuclear fusion raw materials are not directly thrown into the fusion furnace, but the fuel material is first heated and vaporized into plasma before being pumped into the reaction chamber.

Because only plasma can be constrained by the magnetic field, normal matter without charge cannot.

You can imagine how high the technical requirements are here.

First of all, humans must have enough ability to vaporize matter into plasma, and here. Confinement fusion technology plays a key role.

And the so-called pumping into the reaction chamber, this process requires humans to have a super strong magnetic field to accelerate the plasma to the extreme. Only a super strong magnetic field can ensure that the reaction chamber made by humans will not be broken down by ultra-high-speed plasma.

So the thirty years mentioned at the beginning were actually mostly budgeted for research on how to increase the intensity of the magnetic field and how to control the super strong magnetic field.

How to obtain a super strong but stable and controlled magnetic field has also become a topic that humans have been studying hard for the past thirty years.

So how to enhance the magnetic field?

The answer is all in Maxwell's equations.

First, electric current. The magnetic field generated by passing current through a conductor is an electromagnetic field, so the magnetic field strength can be increased by increasing the current strength.

Second, solenoid. Winding a wire around a solenoid and passing current through it can also create a strong electromagnetic field. The more layers of winding, the stronger the magnetic field.

Third, reflector, also called electromagnetic wave reflector. The principle is to reflect electromagnetic waves through the reflector to enhance the magnetic field strength.

Fourth, laser, laser can be used to generate high-frequency electromagnetic waves, and high-frequency electromagnetic waves gathered together will produce extremely strong magnetic fields.

Fifth, high-voltage discharge. Using high-voltage discharge, a very strong magnetic field can be generated in the surrounding environment, but this method is generally only used to study the behavior of electromagnetic fields in different environments.

There seem to be many ways, but in the final analysis, it is still current and coils.

And this is back to the problem of materials science and the research and development of super-strong magnetic field superconducting magnets. Only superconducting magnets can enable humans to obtain ultra-strong magnetic fields with very small changes in magnetic field intensity and remain stable. Because of the material properties of superconductors, it can generate a stable magnetic field in the perpetual current mode, and there is no need to worry about the heating of the conductor due to ultra-strong current.

So how to obtain superconducting magnet materials?

Well. This question is not a big one. After all, as early as the 21st century, scientists used refrigerator conduction cooling to make superconducting magnets, which generated a magnetic field of more than 10T without the use of liquid helium. Some countries have even successfully established a high-magnetic field laboratory of more than 20T through research on superconducting magnets.

T, that is, Tesla, a unit of magnetic field.

The magnetic field strength of 1T is about the magnetic field strength of a 13KG large loudspeaker. The MRI in a hospital is about 3T. The magnetic field strength of a sunspot is about 10T.

The laboratory that can make a frog float in the air can produce a magnetic field strength of about 16T.

In the 21st century, the Chinese Academy of Sciences once created a strong magnetic field of 45.22T, which once broke the record held by America for 23 years.

This magnetic field strength is 900,000 times that of the earth's magnetic field.

However, these magnetic field strengths are far from enough for today's new humans, and are not enough to bind super plasma in a heavy nuclear fusion environment.

You can imagine how difficult it is.

God will not let down those who work hard. Human beings have stood on the steps of countless science and technology. After 30 years of research, they have finally overcome this difficulty. Human beings have finally taken another step forward on the road to climbing the electromagnetic force, the second most powerful force in the universe.

Human beings have finally created a super-strong magnetic field that can bind super plasma in a heavy nuclear fusion environment.

This marks that humans have finally leaped into the ranks of secondary civilizations.

At this time, humans were surprised to find that the super-strong magnetic field they had worked so hard to develop could not only be used to bind the heavy nuclear fusion reaction chamber, but could also be improved and placed in other locations on the warship, forming an array through several super-strong magnetic field generators, and then forming a magnetic field shield.

After achieving heavy nuclear fusion, the technology that was studied for the realization of heavy nuclear fusion was transformed into a magnetic field shield generator for the warship, and everything came to fruition.
