This civilization is very strong, but the technology tree is a bit crooked.

Chapter 115 Superconducting Breakthrough, Electromagnetic Gauss Gun.

"Maglev!"

"Complete diamagnetism of superconductors!"

Seeing this carbon nanowire floating above the magnet suddenly, Chen Yi was taken aback, showing surprise at any moment.

Virtually learned about condensed matter physics.

Chen Yi understood that the magnetic levitation of superconductors.

The essence is a kind of Meissner effect.

To describe it vividly, the resistance of a superconductor is zero.

When a magnetic field appears around a superconductor, it induces a current due to changes in the external magnetic field.

Because the resistance of a superconductor is zero, the resulting current does not decrease.

Then the magnitude of the external magnetic field strength is the magnitude of the induced current generated.

According to Lenz's law.

The magnetic field generated by the induced current must hinder the change of the magnetic flux that causes the induced current.

This law determines that the magnetic flux inside the superconductor is always zero.

The phenomenon shown is that when a superconductor has no current and no magnetic field, a magnetic field suddenly appears around it.

Then the superconductor will generate an induced current because of the appearance of this magnetic field, and the induced current will generate an equal magnetic field, and the two magnetic fields will counteract each other, causing the superconductor to float.

This process of generating a magnetic field due to the induced current and counteracting the characteristics of the external magnetic field, resulting in the zero magnetic flux of the superconductor is called the Meissner effect, and it is also called the complete diamagnetism of the superconductor.

as a standard superconductor.

In addition to zero electrical resistance, complete diamagnetism is also a core property of superconductors.

Superconductors, forever rejecting external magnetic fields from entering their bodies.

"The attribute interface has completely changed."

Chen Yi looked at the property interface of the carbon nanowire.

It is found that after the anti-degeneration breaks through 100, the entire attribute interface has completely changed.

The original properties such as anti-degeneration and conduction have disappeared, replaced by the three core properties of superconductivity.

[Item: Hydrocarbon nano-superconducting material]

[Attributes: critical current x37, critical magnetic field x45, critical temperature x30, tensile strength x64]

[Detecting that a certain attribute exceeds the initial value, do you want to read the information?whether! 】

[Note: This is a carbon nanowire that surpasses the limits of conventional materials, surpasses the current technological ceiling, and involves quantum force field technology. 】

"Carbon and hydrogen nanomaterials. Tensile strength, not falling but rising."

Chen Yi looked at the names and properties of superconducting materials.

Recalling the various properties of hydrogen and the properties of carbon nanometers, I seem to understand something in my heart.

"Read!"

A large amount of technical information and countless electromagnetic-related formulas, including the principles, emerged in Chen Yi's mind.

Even with the assistance of the system, it took Chen Yi nearly ten hours to fully understand it this time.

"Sure enough, as I thought"

After digesting all the information and principles, Chen Yi's eyes showed a hint of bewilderment.

Follow his knowledge of superconducting materials.

What is current superconductivity under normalization, the superconducting gap of Goodstone mode, the phase of electron motion, etc. are too esoteric to talk about.

To give an example in a simple way.

Superconducting material is a special electronic bridge.

Because of the existence of thermal motion.

Normally this bridge of electrons is always shaking, not to mention, there are often some atoms passing through from other places, and Xia Jiba runs around on the bridge.

The electrons don't run smoothly through the bridge deck.

From time to time, it will collide with atoms on the bridge deck, resulting in energy consumption.

But at this time, through an ultra-low temperature, the thermal movement of the substance is suppressed.

The bridge will become stable, and at the same time, other atoms will not be able to pass through other places because of the low temperature and lack of mobility, and run to the bridge deck to hinder the movement of electrons.

Electrons can pass through the bridge smoothly and quickly.

At the same time, it will not collide with other atoms, resulting in energy consumption.

This is the ordinary superconducting material, showing two states of non-superconducting at room temperature and superconducting at low temperature.

The room temperature superconducting material is through a special structure.

Make the bridge more stable, and at the same time build railings to prevent atoms from running to the bridge deck,

In this way, electrons can run extremely smoothly without the need for low temperature.

And now.

This carbon-hydrogen nanomaterial.

It is to build a stable bridge through carbon nanometers, and build a smooth electron channel through hydrogen elements, realizing the characteristics of room temperature superconductivity.

"Thousands of layers of carbon nanoscrolls wrap the hydrogen element in the middle, and then split hydrogen molecules into hydrogen atoms at ultra-low temperature through special electric and magnetic fields.

In the state of hydrogen atoms, the chemical bonds are broken, the electrons bound by molecules become shared electrons, and the covalent bonds become metal bonds, making hydrogen a superconductor.

Afterwards, the electric and magnetic fields are removed.

With the help of strong bearing pressure of carbon nano-rolls.

Maintain the atomic state of hydrogen and maintain the characteristics of room temperature superconductivity. "

"To describe it vividly, this is a multi-layer carbon nanotube that wraps a metal hydrogen core."

"In addition, the structure of carbon nanoscrolls has also undergone some adjustments.

Adjusted carbon nanoscrolls, in addition to the properties of conventional carbon nanotubes.

When the nearby or passing current exceeds a certain threshold, a special gauge field is also formed. "

"This gauge force field can form a Josephson supercurrent effect between each layer of carbon nanoscrolls, forming flux quantization, and turning carbon nanoscrolls that are not superconducting into a superconductor."

Digest the last message.

There was a hint of surprise in Chen Yi's eyes.

If according to the physical characteristics of the normative force field of carbon nano-rolls.

Strictly counting this carbon-hydrogen nano-superconducting material, the main body is still carbon nano-scrolls, and the metal hydrogen inside can only be regarded as a starting core.

Because when the current reaches a certain level, the carbon nanoscroll itself will undergo the Josephson supercurrent effect, changing from a non-superconductor to a superconductor.

However, there is no conduction of metal hydrogen in the middle.

Just relying on the carbon nano-scrolls at normal temperature, if the required current cannot be reached at all, it will be overloaded and blown due to the resistance value.

If you want to start it, you can only start it at ultra-low temperature, and then remove the low temperature without stopping the power supply.

Once the power is turned off and you want to restart, you only have to repeat the process once.

The intervention of metal hydrogen is equivalent to acting as a starting condition, and superconductivity can be started without ultra-low temperature.

"Such a superconducting structure means that it is easier to improve superconducting performance."

"Just the number of stacks is enough."

"The more layers, the stronger the Josephson supercurrent effect, and the stronger the superconducting performance."

"It was a pleasant surprise."

Chen Yi sighed in surprise.

Just because normal-temperature superconducting materials are manufactured, it doesn’t mean they can always meet the demand.

It's the same as a chip.

Different superconducting materials also have different superconducting properties.

The three critical points of a superconductor are critical magnetic field, critical current, and critical temperature.

When the strength of the external magnetic field reaches a certain level, the superconductor will lose its superconducting properties.

When the internal current reaches a certain level, the superconductor will lose its superconducting properties.

When the temperature reaches how much, the superconductor will lose its superconducting properties.

These three limits represent the practicality of superconducting materials. If they are too low, even superconducting is useless.

"Test the critical performance of this carbon-hydrogen nano-superconducting material."

Chen Yi went to the laboratory, spent four days to produce a carbon-hydrogen nano-superconducting wire with a length of more than ten meters, and then conducted some tests.

Finally, approximate performance parameters are obtained.

"The critical current is 13.3KA/mm^2, the critical temperature is 47.8 degrees Celsius, and the critical magnetic field cannot be fully filled due to site and equipment constraints. Only the strength of 16.2 Tesla can be measured, and the superconducting phenomenon still exists."

Chen Yi recalled that the EAST nuclear fusion project team realized that the stable magnetic field strength achieved in the tokamak seemed to be less than 13 tesla.

Now that's at least a magnetic field strength of 16.2 Tesla.

Not only can it meet the basic requirements for confinement ignition, but it can also reduce the magnetic field range of nuclear fusion to achieve high-constraint and high-density operation.

"So this wire can be used as the basic material for a nuclear fusion device?"

"It's fake! I didn't use much force."

Chen Yi's expression was both strange and surprised.

Although, it took him a virtual learning opportunity to engage in room-temperature superconducting materials this time, three days plus three days plus one day, and it took him a week before and after.

But here, it is mainly chemical production, which is too anti-technical and time-consuming for him.

99 preparations, [-] failures, nine out of ten successful ones are also defective and unusable.

It's a perfect expression of his chemistry talent.

If you go to make explosives, [-] lives may not be enough to explode.

If it wasn't for Yifei's rich, local tyrants, he wouldn't care about the cost.

At the same time, more than a dozen instruments and dozens of groups are used together, and a large amount of precious raw materials are used at no cost.

I am afraid that Chen Yi is still in the laboratory holding test tubes and preparing liquids.

The time spent on actually researching superconducting materials is probably less than a day.

Chen Yi calculated the breakthrough of room temperature superconducting materials in his heart.

What kind of improvement effects can be brought to some technologies at this stage.

"Controlled nuclear fusion cannot be fully calculated for the time being."

"However, if the critical current of 13.3KA/mm^2 is used to improve laser weapons, replace the wires and capacitor materials of the light source conversion device, and replace all the wires.

The efficiency can be increased by at least 60%, and the power can be increased by 40%.

Equipped with a redundant cooling system, this can also be greatly reduced for lightweight design. "

"Ion propulsion, as well as the polar magnetic motor of the new moon landing drone, can be replaced by superconducting wires, and the efficiency can also be increased by more than 50%."

"For new energy motors, if the superconducting wire is replaced, the overall efficiency can be increased by more than 30% without the heavy cooling system."

"This room temperature superconducting technology is indeed the foundation for civilization to go to the stars."

"A breakthrough is a breakthrough in comprehensive technology."

"Make something, actually try the performance of the superconducting wire."

"Think of it as relaxation and reward after a week of hard work."

Looking at the loss after testing, there were only a little over 10 meters of carbon-hydrogen nano-superconducting wire left, and Chen Yi immediately became interested.

Nuclear fusion is still not working, magnetic confinement is improved, and problems such as plasma turbulence have not been resolved.

It is not enough to solve superconducting materials now.

As for laser weapons, it needs to be tested by drones or intercepting missiles to truly reflect the effect, which is a bit troublesome in a short time.

"Superconducting, Electromagnetic"

"Multi-stage coil reluctance electromagnetic accelerator is commonly known as Gauss gun, this one can."

Chen Yi remembered the Gauss gun he had played with in private before.

At that time, because I was afraid of too much punishment, and the conductivity of the copper wire was not enough, the resistance generated too much heat.

The power and acceleration performance of the coil can't be added at all.

Slightly increasing the voltage will burn the coil, and it will cool down after a few shots, which is not pleasant to play at all.

Now, if you use a supercapacitor of a laser weapon, pair it with a superconducting wire, and build a Gauss gun, the power will definitely be different.

"The boy who saw Gundam."

"Who doesn't dream of owning a Gaussian gun that shoots satellites from the ground."

Do what you want.

Chen Yi quickly found some basic accessories and started making.

The 1.3-meter-long acceleration guide rail and the 18-level acceleration coil allow the warhead to have enough acceleration time.

At the same time, the special magnetic resistance design can perfectly offset the kinetic energy of the reaction force through the buffer of the magnetic field, and then convert it into heat energy and release it.

In order to ensure that the heat will not affect the superconductivity of the superconducting wire, Chen Yi specially designed a heat insulation layer for the coil and an efficient heat dissipation pipe.

The magazine for 6 warheads is made of high-strength and high-temperature-resistant tungsten alloy, and some superconducting materials are embedded on the surface to improve the electromagnetic acceleration efficiency.

The gun body and shell made of carbon fiber ensure the lightweight design of the gun body while ensuring strength.

The supercapacitor of the laser weapon can release energy instantly to form the most powerful pulse acceleration effect.

Using the latest breakthrough of Yifei, the 2000wh/KG carbon-silicon lithium battery pack is packaged into a gun stock and handle.

The total capacity reaches 14 kWh, and the detachable design makes it easy to replace the energy magazine at any time.

Finally, consider the accuracy of ballistic aiming, in addition to conventional scopes and infrared sights.

Chen Yi also thoughtfully designed a simple online radar sight.

It can wirelessly connect the radar and the fire control computing unit, calculate the flight trajectory of the target and the orbit of the space satellite, and provide support for the design of the trajectory, so as to achieve one shot into the soul.

Because it's just technology integration, no new technology is involved, and Chen Yi has previous experience.

Less than three hours.

An electromagnetic Gauss gun weighing 13.4 kilograms, dark all over, and plain in appearance appeared in Chen Yi's hand.

[Item: Space Grade - Electromagnetic Gauss Gun]

[Attributes: Energy x23.4, Attack x49.8, Strength x19.8, Control x34.9, Aim x16.7 (59.8)]

[Note: This is an electromagnetic Gauss gun that transcends reality, is well-designed, and has a big brain hole. The acceleration of multi-level superconducting coils can accelerate bullets beyond the second speed of the universe.

Bases up to the moon, satellites in space, and aircraft and tanks down to planets are all within its attack range. 】
