Vol 2 Chapter 516:

As for the topic of urban networks, with the withdrawal of the announcement, it has gradually disappeared from the Internet, and new topics have become the object of discussion.
At midnight on November 15th, it was sunny.
On this day, the holographic city plan was officially opened, and people led by Zhao Jun naturally held a lively launching ceremony.
When Zhao Jun held their launching ceremony, the young men and women of Anhe naturally ran their streets with their Pokémon.
For them, today, it is not only the full launch of the holographic city plan of Anhe City, but also the holographic game that they are more concerned about is also landing in this city.
In this cross-generational game, the map scale is one to one. If you want to catch more elves, it is almost impossible to stay at home.
The game also encourages everyone to go out often to find those Pokémon hidden in the streets or park bushes.
Zhang Chao is an anime fan who loves Pokémon. Of course, he has not missed any game related to Pokémon.
When the holographic game appeared, he immediately followed. On the first day of the sale, he started with professional equipment, an elf ball, and a magnetic bracelet.
The day of November had begun to cool down, and Zhang Chao was wearing a long beige sleeve with a Pokémon printed on his chest.
Beige long sleeves with a pair of black sports trousers, and a pair of white canvas shoes, coupled with the short hair he deliberately repaired, the whole person looks extremely spirited.
At this point, Zhang Chao was walking with his original elf, the little fire dragon, in an alley not far from his house.
A few meters away from him, the same man looked at the alley with a small fire dragon.
Zhang Chao didn't bother with that person, his gaze also glanced around, "The game has begun, why haven't you seen the wild Pokémon?"
Zhang Chao looked for a moment and found nothing, which made him frown.
Just as he was going to change places to look around, he suddenly heard the sound of "Dangdang" next to a trash can he was passing by.
Zhang Chao quickly turned around and looked. The trash can is a common white rectangular trash can in the city with red letters on it, but what attracts him most is the thing next to the trash can.
This is a pokemon that looks like a fox. It has short and thin four legs, and has watery brown eyes, the same color as its entire body of hair.
The fluffy tail was flicking lightly at this moment.
"This is ... Ibrahim!" Zhang Chao took a breath, and there was a touch of excitement in his eyes. Ibrahim, this is a very rare elf!
Just as Zhang Chao was stunned, this freshly baked wild Ibrahimovic suddenly screamed softly, turned around and jumped away, Ibrahimovic was fast, and disappeared in the sight of Zhang Chao in the blink of an eye.
Zhang Chao stayed a bit, although the technology crystallization company has been emphasizing that this game is very real, but this experience is the first time!
When he reacts and catches up, where can I still see Ibrahimovic's shadow.
"I rub it, this is running too fast!" Zhang Chao looked at the disappearing invisible Ibra, and cursed with his in place.
Without Ibrahimovic, Zhang Chao could only curse and leave this alley, walking towards the road.
At this point, the elf becomes more and more, but you can see very common and common elf. For example, the green caterpillar on his head is spinning ...
"Um, it's better than nothing." Zhang Chao was going to grab one head first. If he wasn't satisfied in the future, he could release it.
And there are too many people who have the same experience as Zhang Chao. After seeing the wild Pokémon for the first time, they will hold on, and then look at each other.
But when they were watching, these wild elves had already run away.
Not to mention that these people started playing their own games, Cheng Yuan has been paying attention to the construction progress of the particle accelerator during this time.
After all, on the satellite side, Zero has been monitoring and controlling, and the asteroid trap has no problems, so his focus naturally shifted to the particle accelerator.
The construction of particle accelerators should not be careless. Because the building above adopts a new anti-gravity technology building, it can be said that there is no weight!
In this way, the tunnel where the particle accelerator was excavated earlier was very embarrassing, because without the above weight, his rotating tunnel of 60 meters underground and 8 meters in diameter naturally appeared a lot.
Moreover, the reinforcement of the walls around the tunnel was also wasted. In this regard, Cheng Yuan could only indicate that his plan could not keep up with the changes. At the beginning, he did not expect to build a cutting-edge laboratory into an anti-gravity technology building.
It is not far away and these reinforcements have not been cancelled. Anyway, the materials are ready. As long as the engineering robot is installed, it will not waste much time.
At this time, Cheng Yuan was building a small titanium pump on the test bench.
Titanium pump is an important joint point in the internal structure of particle accelerator. The structure of particle accelerator generally includes three main parts.
The first part is the particle source, which is the particles that need to be accelerated, such as electrons, positrons, protons, antiprotons, and heavy ions.
The second part is the vacuum acceleration system. Its role is to prevent the particles from being affected by the scattering of air molecules, so that the entire vacuum tube maintains a high vacuum inside the vacuum chamber.
The last one is the guidance and focusing system. This system is the electromagnetic field in the particle accelerator. Cheng Yuan was also worried about the influence between the magnetic fields, and that is it.
The particle accelerator Cheng Yuan wants to make is not the accelerator that needs to be controlled by vacuum tubes. The particle accelerator he created is a huge annular space.
In addition to protecting this special particle accelerator on the wall reinforcement, another reason is that a large number of superconducting magnets need to be installed inside.
Except for the annular part, the whole space is covered by superconducting magnets.
In other words, Cheng Yuan intends to turn the entire annular space into a huge vacuum chamber. Such a move is undoubtedly the most daring!
The so-called Yi Gao people are bold, and Cheng Yuan has such technology. Naturally, he will not worry about any problems, but the theory is theory. In practice, Cheng Yuan still needs to pay attention to it.
And the titanium pump is one of the keys!
When the particle accelerator is working, it is required to maintain a very high vacuum state inside. Under this high vacuum state, a high electric field is allowed to build up inside without sparking, and at the same time to prevent cathode pollution.
And titanium pump is a kind of equipment for manufacturing high vacuum environment!
The titanium pump in Cheng Yuan's hand is different from the general titanium pump. The general titanium pump is "concave". In the middle, a thick stainless steel cylinder with a thick thumb is arranged. These stainless steel cylinders are arranged in a honeycomb shape. The "magnet" and these stainless steel cylinders are separated by a titanium cathode plate, and the anode stainless steel cylinders just cause the effect.
But Cheng Yuan ’s titanium pump is like a CD disc. The main body is a superconducting magnet. The surface is covered with a titanium cathode plate. The round hole reserved in the middle is where the stainless steel sheet is installed.
There are a total of six test benches, one row and two rows in three rows, connected to the line, and Cheng Yuan handles them to the assembly room.
In the assembly room, several robotic arms have temporarily set up a half-height black box with a circular slot in the middle of the six sides. The size and shape are exactly the same as the titanium pump in Cheng Yuan's hand.
Cheng Yuan installed the six titanium pumps in his hands, plugged in the stainless steel sheet, "zero, start the device. Let's try its effect." Cheng Yuan patted the top cover of the black sunspot and instructed.
Cheng Yuan got up and stood three meters away from the black box. He opened a holographic screen and was ready to observe the internal state of the box at any time.
When the power is turned on, when the current is turned on, the electrons quickly pass through the titanium cathode and the stainless steel anode. The electric field pressure inside the box changes instantly. A high voltage is applied between the cathode and the anode, and the electrons inside the black box begin to change the direction of movement.
Because the titanium pump is circular and diffused, when six titanium pumps act on the inside at the same time, the electrons inside form a special circular movement.
Cheng Yuan stood outside and observed through the holographic screen ~ EbookFREE.me ~ to find that the gas molecules inside the black box collided madly with electrons, generating a large number of positive ions and secondary electric ions.
This efficiency is more than ten times faster than ordinary titanium pumps!
When Cheng Yuan watched this change with his whole body's attention, the information on the holographic screen was changed again. Positive ions bombarded the titanium cathode and sputtered out titanium atoms. The titanium atoms fell in the middle of the stainless steel anode to form a titanium film. .
The role of this layer of titanium film is to absorb the active gas inside the black box, and then the internal inert gas is ionized and discharged.
This process is extremely fast, and Cheng Yuan can't fully see it. In his holographic screen, he only sees an internal circular electric field.
This circular electric field is not only more efficient than ordinary, but also produces a more pure vacuum environment. However, after the experiment, Cheng Yuan found through monitoring that at the end of the experiment, the purity of the vacuum environment was even more subtle!
He frowned and hurried forward to check.
"Sir, the anode is scrapped," said Zero when Cheng Yuan stepped forward.
After turning off the power, Cheng Yuan picked up the titanium pump and took out the stainless steel sheet acting on the anode in the middle. It was found that the smooth stainless steel sheet had many dense points at this time, like the surface of a cement wall.
"It's completely scrapped!" Cheng Yuan reluctantly threw away the stainless steel sheet in his hand, but he didn't want to replace it. After all, the particle accelerator is not a commonly used device, and this is just a small experiment, a half-height black box It is really embarrassing these six titanium pumps.
According to Cheng Yuan's estimation, at least three can be installed on each side.
The most important thing is that Cheng Yuan has proved through his own experiments that this thing is completely effective, and there is no error caused by the change of shape. (To be continued.) How good is the book, the book's home! Unique URL:
