I am the only one who practices magic: I practice magic in the city

Chapter 429 Hand-Rubbing Tokamak (4653)

Main plane, Mount Omiz.

In Adrian's life laboratory, the original creation capsules had already been put away by Fang Yu, and replaced by dozens of Weichai 2000-kilowatt diesel generator sets.

These diesel generators were obviously running, but due to the effect of "silence magic", no roar was heard.

"Flow regulator."

"Pulse power."

"High vacuum pump."

"SIB interface board."

……

In front of the workbench, Fang Yu was concentrating on using various tools to assemble a spherical object with a diameter of more than 40 centimeters.

Every time Fang Yu said the name of a part, Youzi would use the magician's hand to hand the corresponding part to Fang Yu.

“The cavity accuracy ± deviation value meets the design requirements.”

Every time Fang Yu installed a component, Youzi would scan it to check whether it was consistent with the design drawing.

It's just that the voice sounded muffled, without the previous liveliness and excitement.

"This is a crucial step."

Fang Yu held a piece of processed original furnace slag and cyber steel in his hands. With a slight movement of his mind, he used the primary transformation essence. The slag of the original furnace began to deform in his hands and automatically turned into hundreds of long wires.

At the same time, the Cybertron steel in Fang Yu's hand began to change. The hard insulating metal flowed upward along each wire like venom, coating the wires formed by the superconducting slag with a coating no more than 10 microns thick.

Next, these hundreds of wires are wound around 12 coil substrates made of Cybertron steel in an extremely complex spiral winding manner.

In just one or two minutes, twelve delicate coils with a diameter of only four or five centimeters were floating quietly in the air. No. 12 collected them one by one, put them in a box, and then put a label of TF coil on it.

This process was repeated several times, and dozens of coils of various sizes were made. Fang Yu then used instruments to check the current passing through one by one, and then installed these different coils at different positions on the spherical object.

The tokamak device is extremely complex. Even if the slag of the original furnace has extremely good superconducting properties and can maintain superconducting properties and current density comparable to gold within 500 degrees Celsius, and no longer requires a large-scale and complex liquid nitrogen cooling system for hollow cooling, it is still a very arduous challenge for one person to build a functioning tokamak.

Fortunately, Yuzi’s design plan is very complete. Except for superconductors and thermal insulation materials, most other parts can be found in customized manufacturers in Da Zhou. The only problem is cost.

Cost is not a problem for Fang Yu.

The two most core sets of superconducting coils and plasma cavity need to be handled by Fang Yu himself.

For Fang Yu, who has mastered the essence of primary changes, it is relatively simple to make these components made of a single material.

"Huh, it's basically done. We can use nitrogen to test the stability of the magnetic field that confines the plasma."

Fang Yu rubbed his hands with interest.

Finally, it was done. As long as the subsequent experiments are really successful, the energy crisis of mankind will disappear completely!

The tokamak miniaturization solution proposed by Youzi adopts a spherical tokamak solution. In addition to not requiring a cooling system, it also eliminates the central magnetic field coil, further reducing the size of the tokamak.

What makes Fang Yu most satisfied is that the material breakthrough of Cybertron steel and superconducting slag avoids material degradation of the entire system caused by radiation and high-energy particle bombardment. Therefore, the tokamak made using this solution no longer requires the intermediate conversion of nuclear energy - thermal energy - mechanical energy - electrical energy.

In simple terms, we finally don't have to boil water to generate electricity. The high kinetic energy of high-speed charged particles is directly converted into electrical energy through electrostatic and magnetoelectric converters, which greatly improves the energy conversion efficiency and reduces energy loss. At the same time, it also simplifies the system and greatly reduces the manufacturing cost and complexity of the maintenance system.

In addition, by controlling the fusion reaction through magnetic confinement, the fusion reaction and energy conversion process can be precisely controlled, and it can also have a faster response speed, adapt to changes in electricity demand, and have less impact on the power grid.

Before conducting a real fusion experiment, it is necessary to first use nitrogen to verify the effectiveness of the entire system in confining plasma.

Nitrogen itself is not a fuel for fusion reactions, but by exciting nitrogen into plasma, its physical behavior can be used to verify the effectiveness of the device.

If it works, we will continue to study using a large model of the tokamak control unit to improve the control effect.

Fusion testing can only be carried out after the safety of the system has been thoroughly verified.

"Using 380V and 50A will produce an internal magnetic field strength of approximately 12.5 Tesla, which is sufficient to confine the plasma."

After Yuzu said this, she fell silent again.

The magnetic field strength of 12.5T has far exceeded the highest strength of 3T in nuclear magnetic resonance, but this strength is mainly internal strength, which is used to confine the plasma in the sphere. After internal cancellation, the magnetic field strength outside the device is already negligible.

The strength may be only about 0.02T, which is not even as strong as a stronger magnet.

The outer shell also has radiation and magnetic field shielding layers, which lock the remaining magnetic field firmly inside the tokamak.

Fang Yu connected the tokamak to the laptop, turned on a few switches, and performed a system test first.

Everything is working fine with the system.

After injecting a small amount of nitrogen into the spherical tokamak through the injection port, Fang Yu pressed the ignition switch on the back of the tokamak. With a hum, the nitrogen in the spherical plasma chamber began to rotate rapidly, and at the same time, the temperature of the nitrogen in the chamber began to rise.

Under the heating effect of the electric current, the temperature of the nitrogen in the cavity gradually rose to the 180,000 Kelvin temperature required for nitrogen ionization. At the moment the temperature was reached, the nitrogen in the cavity turned into a ball of shining blue-purple light.

Under the constraint of the magnetic field, this ball of plasma emitting blue-purple light rotated rapidly along the magnetic lines, gradually forming a vortex of blue-purple light like the Milky Way.

The first step of the experiment was successful!

Fang Yu waved his fist vigorously.

This shows that the magnetic confinement of high-temperature plasma by this spherical tokamak is effective!
Next is the second step of the experiment.

Fang Yu turned off the power, picked up the tokamak and put it into a dark metal box. The data cable and power cable of the equipment came out through a hole at the bottom of the box. After reconnecting the power supply and computer, he threw a Geiger alarm into it and then closed the door.

We just tested the plasma magnetic confinement capability of this micro tokamak by heating nitrogen to 180,000 degrees to achieve an ionized state, but a real fusion reaction requires a high temperature of at least 100 million degrees.

However, if one wants to maintain a stable and controllable fusion reaction and have sufficient economic benefits, a high temperature of 300 million degrees is the basic requirement.

Next, what Fang Yu needs to do is to gradually increase the temperature inside the tokamak to 300 million degrees to test whether the tokamak can withstand such a high temperature and whether high-energy particles will penetrate the shielding layer and cause radiation.

Nitrogen plasma will not produce fusion, but at a high temperature of 300 million degrees, almost all matter will lose electrons and become extremely radioactive.

At the same time, such high-temperature plasma will become more unstable, placing higher demands on the magnetic confinement capabilities of the tokamak.

Fang Yu's life essence has been elevated to the pinnacle of carbon-based life. Radioactivity basically does not cause damage to his DNA. He is not worried about radiation. He is mainly worried that after he is contaminated with radiation and returns to Blue Planet, it will affect the people around him.

After restarting, the tokamak quickly heated up to over 180,000 degrees and the plasma was re-formed.

The difference is that this time the heating method in the device is not just electric current heating. The radio frequency heater and high-frequency microwave generator integrated in the tokamak start to heat the plasma at the same time, and the temperature of the plasma rises rapidly. In just a few tens of seconds, the temperature of the plasma has reached more than 50 million degrees! At this time, a small nozzle made of cyber steel in the tokamak sprays a small ball of neutral hydrogen towards the plasma vortex.

Under high temperature, this ball of neutral hydrogen quickly formed hydrogen ions, further increasing the plasma temperature in the tokamak's spherical cavity!

Sixty million! Seventy million! Eighty million!
……

On the computer screen, the plasma temperature monitoring kept jumping at an extremely exaggerated speed, quickly exceeding the 100 million Kelvin temperature that Fang Yu had seen on the ETPD in Kevin Stone's experiment some time ago.

One hundred million Kelvin is basically equivalent to one hundred million degrees Celsius, with little difference.

When the temperature reached 180 million Kelvin, the temperature stopped increasing.

The more than 20 diesel generators around it are also running at full speed, continuously providing energy to this small tokamak through superconducting wires.

This is the heating limit that this micro-tokamak can achieve when relying purely on electric current heating, radio frequency heating, microwave heating, and neutral beam heating.

So far, there has been no movement from the Geiger alarm in the box, indicating that the shielding layer of this small tokamak does indeed completely shield the particle radiation generated under high temperature.

At the same time, at this temperature, the tokamak's confinement of the nitrogen plasma can still remain stable.

Although this has reached the required temperature for the deuterium-tritium reaction and even the deuterium-helium-3 reaction, it obviously still does not meet Fang Yu's requirement of million Kelvin.

But this is already the temperature limit that can be achieved in such a small tokamak with current technology.

Of course, if it is real nuclear fusion, Fang Yu can try to use the self-reaction heating device inside the tokamak, and use the energy generated by fusion to continue heating the plasma until the temperature requirement reaches more than 300 million degrees.

But obviously, there is no way to achieve self-reaction heating when using nitrogen plasma.

Fang Yu opened the lead box, picked up an octagonal black stone next to it, stuffed it into a triangular depression at the top of the tokamak, and lightly tapped his fingers, injecting two hundred units of magic power into the black crystal.

"Incendia Crescere Ignis!"

Along with Fang Yu's spell, red lines appeared on the octagonal black stone, which seemed to be runes one by one.

Inside the spherical tokamak, at the north, south, east and west poles, four tiny magic arrays engraved on the cybernetic steel on the inner wall of the cavity also lit up at the same time. Four white rays of light suddenly shot out from the magic arrays and intersected in the vortex formed by the nitrogen plasma!

Almost instantly, the nitrogen plasma burst into an intense blue-white color!
The temperature on the laptop also suddenly jumped to 350 million degrees!
"Temperature Multiplication", a 4th-ring array of the School of Transmutation, was a array often used by alchemists on the main plane before the construction of the original furnace.

This magic array can increase the temperature of the alchemy furnace by up to twice.

The moment the temperature soared, the plasma vortex in the cavity twisted violently, as if it was about to break free from the surrounding magnetic field and pounce on the inner wall made of cyber steel!
But then, the magnetic lines of force in the spherical cavity changed, continuing to firmly confine the leaping plasma within the magnetic field.

After a few seconds, the blue-white plasma resumed its stable rotation, like a rapidly rotating galaxy floating in a spherical cavity.

Call ~
Fang Yu breathed a sigh of relief.

He had already prepared to unplug the power cord if things didn't work.

After waiting for another minute or two, the tokamak continued to run stably and there was no movement in the Geiger counter.

OK! It works!
Now it's just a matter of keeping it running smoothly and seeing how long it lasts.

Fang Yu looked at the time and found that there were still ten minutes left before the one and a half hour agreed upon by him and Liu Feifei.

"Okay, Yuzu, we can switch back to Blue Star. We'll leave this thing here for now. The generator has enough diesel to run continuously for three days. We can come back in two days to check on the operation status."

Fang Yu was in a good mood and patted Youzi who had been silent.

Huh? Why is the ball so obedient today?

If it were in the past, it would have already started bragging after giving some symbolic compliments, right?
"Master." An unusual bluish-gray color appeared on Yuzu's body, making her look a little melancholy.

"Can I ask you for something?"

Fang Yu's mind moved, and combined with the nature of this ball, he guessed: "A request? About Liu Feifei? You saw it, I don't want to touch her."

"No, Master." Yuzu was silent for a moment, "I want you to help her, she is so pitiful."

"How can I help her? Her current life is her own choice. She wants it this way. What can I do?"

Fang Yu, who had been accustomed to seeing beautiful women in Tongque Tower since he was a child, had never had the intention of "persuading prostitutes to become good women".

"But, but this is not her own choice!"

Yuzu's body glowed, "She just forced herself to accept it. Besides, she was so young at the time and had no right to make her own choice."

Fang Yu rolled his eyes. This ball was really innocent. He and Huang Xiang could have something in common.

Fang Yu didn't have any idea that "She earns more money in a day than an ordinary person earns in his entire life. Instead of feeling sorry for such a female star, you might as well care about how much money you can earn."

Because this is an "irrelevant comparison", a very typical logical fallacy, it will cause bugs if used in a program.

This "if you pity A, you don't care about B" statement actually sets up a false dichotomy. The two are not contradictory, and people can care about both at the same time.

Besides, who isn't curious about gossip, especially gossip about female celebrities?

Obama also gossiped about how Mariah Carey got divorced.

You pretend to be aloof from the world all day long, while everyone else is drunk and you are the only one sober. Aren't you tired?
The point is that when you say this, I don’t see you making any extra money.

However, even so, Fang Yu did not want to interfere in Liu Feifei's life. If he did not want to find the secret of spiritual power growth through Liu Feifei, after the Bazaar Charity Night, he might never have any intersection with her in this life.

"Although she is not the real Ling'er, she is much more pitiful than Ling'er. You can see that her life has been shattered under her mother's control."

Yuzu's voice was very low: "Master, I just hope she can be happier, or at least help her solve the problem of her second personality. If this goes on for a long time, I'm worried that she will eventually collapse spiritually."

Fang Yu sighed and patted Youzi: "Happiness is a subjective feeling. What I can do is to give her more resources. Her second personality has already been formed. In a sense, it is also a separate person. Let me ask her if she is willing to merge the two personalities again. If she is willing, I can help her merge them."

"But don't hold your hopes too high. She probably doesn't want to merge."

"Why?" Yuzu didn't understand.

Fang Yu hummed and said nothing.

Two personalities fall in love with each other and can fall in love just by being in a daze. How diverse is this situation that does not even cover the 97 gender and orientation identities.

Fang Yu picked up Youzi and took another look at the status of the tokamak. Well, it was still running normally, and then he started the switch.
