Chapter 268 Accelerator Project
With the dazzling light emitted by the LED lights on the wall, Tiger discovered that after the wide hole that several people entered, they entered a room that resembled a sealed cabin. On the white walls hung a long string similar to that of a laboratory. Protective clothing sealing suit.

"Please put on your sealing suit. The internal venue has extremely high dust-proof requirements." The receptionist on the side said while demonstrating the essentials of wearing it. He held up a transparent round helmet in his hand and continued: "No matter what time, You can't take off the helmet. The environment inside is full of inert gas. If you take off the helmet, you will definitely die. When you talk, you can press and hold the call button on your left arm, which has the pattern of a mobile phone printed on it."

Each person removed a suit from the wall and put it on with the help of another person.

When everything was ready, nearly an hour had passed. In the process, Tiger looked around and found a small closed door on the opposite side. There was a red light on the small door and a digital display on it. What is displayed is the various values ​​​​of the table, which are marked in Chinese and English.

The resistance level is XXMPa, and the sealing performance: when the overpressure is 100Pa, the air leakage is ≤0.01m/h.

After the heavy helmet was tightened, Tiger discovered that a transparent display appeared in the upper left corner of the helmet, somewhat similar to a projection screen. It displayed a series of data and charts. Tiger could only determine that this was the internal system of the sealed suit. Self-test status data.

Immediately afterwards, he heard a buzzing sound coming from outside. It seemed that something was activated. The air pressure on the door was also dropping rapidly. Five minutes later, the air pressure dropped to 0. After waiting for another five minutes, the air pressure gradually dropped. When the height reached the normal value, the red indicator light on the door turned into a green light, and the door opened, revealing a long passage, with a ventilation sealed room at the other end.

It took more than an hour for this group of people to truly step into the mysterious accelerator project.

This is a transition cabin from atmospheric environment to vacuum and then to inert gas. If this is the case, the entire cave in front of you should be in this kind of environment. The only thing Tiger can confirm is that the amount of work is unimaginable.

"This is the main control area," the receptionist said.

Liu Zeyi's voice came from the headset, "Comrades, witness the miracle."

"Leader, is there any breakthrough in the research on stone slab crossing?" Tiger asked.

"Everything has just begun. How could it be so fast? The legendary quantum computer still only has a theoretical model, and its realization is far away. But what I didn't expect was that there would be a breakthrough in the research on the most supernatural slate."

"When we first started working on the slate, no, it should be the sealed coordinate information. No matter how we physically touched it, it couldn't work with it. At that time, someone thought that something might work, and that was high-energy particles."

"You mean using a high-energy accelerator?"

Liu Zeyi nodded. High-energy accelerators are the main experimental research tools for high-energy physics.

That is, a strong magnetic field is used to accelerate charged particles, such as electrons and protons, to very high speeds, and then collide with the target material. The result of the collision can produce a large number of new elementary particles or new phenomena.

Through the observation and analysis of these new particles and new phenomena, we can continuously deepen our understanding of the microstructure of matter.

Tiger finally knew the meaning of the accelerator he mentioned before. He should have thought that this is the most commonly used accelerator in high-energy physics experiments, but in his cognitive ability, usually high-energy accelerators are ring-shaped, and this kind of It is a straight line extending for two thousand kilometers through twenty acceleration rings.

At this time, the same question was asked by another person: "Why not use a circular orbit structure?"

"Please explain this principle to Professor Chen," Liu Zeyi said.

"We also use ring structures, but what we need more is to amplify the results. The ring orbit allows charged particles to pass through the same acceleration gap repeatedly. When a radio frequency electric field synchronized with the particle gyration period is loaded on the gap, the particle energy Will be able to grow multiple times.

This kind of cyclotron uses a constant deflection magnetic field to guide the deflection of the particle beam, and uses a constant radio frequency electric field to accelerate the particles. The gyration radius of the particles in the accelerator increases with the energy growth. Its energy limit is mainly determined by the volume of the deflection magnet. The energy Usually lower. "

"And the beacon we are studying, which is what you call the stone slab, the result of this kind of bombardment is too weak, so an acceleration ring is needed to amplify it."

The tiger raised his hand and asked, "How big is it here?"

"This is the head of the accelerator, which is the core part. It is all located 200 meters below the ground. It is divided into the initial acceleration part of a circular tunnel with a circumference of 30 kilometers. It is the ring-shaped accelerator structure just mentioned. It is larger than the largest The LHC is still 3 kilometers long."

Tiger knows about the LHC. He did a lot of homework before coming here. It is the Large Hadron Collider. This international cooperation project was jointly funded and built by universities and laboratories with more than 34 physicists in 27 countries. , including a circular tunnel with a circumference of 50 kilometers. Due to the local topography, it is located between 150 and meters underground. The tunnel itself is three meters in diameter, located on the same plane, and runs through the border between Switzerland and France. Most of the main part is located France.

However, the project here is obviously larger than that of the LHC, because the LHC tunnel itself is located underground, and there are many above-ground facilities such as cooling compressors, ventilation equipment, control motor equipment, and freezing tanks, etc., which are obviously built on top. Located in the Qinling Mountains and surrounded by inert gas, even this large-scale project is only the acceleration part of the entire project and cannot be compared to the same. In this set of circular accelerator channels, two proton beam tubes are mainly placed.

The accelerating tube is surrounded by superconducting magnets and cooled by liquid helium.

The protons in the tube run in the opposite direction around the entire ring accelerator, and are then extracted through the bent crystal beam and enter the synchrotron radiation area along a straight line, followed by the emission area and its data processing center.

The material bombarded by the particle emission is launched into the first acceleration ring a hundred kilometers away.

"You mean to launch protons and accelerate them through twenty accelerating rings? Bombard the stone slab?" Tiger said in shock. The reason why he was so shocked was that experiments in this area had already been done in previous international cooperation research, and there was no What result.

"No, the emitted protons do not bombard the stone slab through an accelerating ring, but directly bombard the stone slab, and then amplify the bombardment results through twenty accelerating rings, and then get the result at the end."

The electric car drove along the two-way lane on the edge of the tunnel wall. Tiger looked at the straight tunnel with no end in sight. If it weren't for the nameplates on the huge cylindrical equipment in the center of the tunnel marking different areas, it would have been as if they were circulating in the same space. .

Can't tell exactly how long it is.

"We don't know the specific principle of making the beacon, but if we don't know, we can use it as a reaction black box, output through it, and then continuously amplify the results. That is, we used this principle to conjecture that we built this equipment."

Along the column, we arrived at a huge space area. This is the black box part of the accelerator. It is a spherical black box that gathers a large number of pipelines. The middle is empty. The stone slabs will be placed here for experiments after all construction projects are completed.

There are currently only two known stone slabs that serve as communication channels between the three worlds, and a large amount of people and materials are exchanged every moment.

"The project is expected to be completed in two years at the earliest." The receptionist's eyes were full of hope and desire, which was the look of a scientist exploring the unknown.

"Will it be useful?" Tiger stood aside and looked up at the spherical black box hanging in mid-air. The entire spherical shape was divided into three layers. The outermost layer was densely connected with three-meter-diameter pipelines. Various devices basically had no shells. , completely without the simplicity of commercial products, but full of roughness and complexity, like the handiwork of a model beginner, "It really looks like a womb."

"We have initially tested pions, protons, neutrons, electrons, deuterons, alpha particles and other heavy ions. We used these directly accelerated charged particles to interact with beacons and found that a variety of charged and uncharged particles can be produced. Secondary particles, look, at least they finally work, right?" The receptionist shrugged, "It's just a scientific experiment."

The tiger followed the receptionist tremblingly as he walked on the 30 cm wide bridge in mid-air. His heavy sealing suit boots made a thumping sound when he stepped on the thin steel plate bridge deck.

He walked forward a few meters and looked back, but no one else followed him.

He walked a few steps, crossed the connecting temporary bridge, and arrived at a five-meter-square fenced platform. At this moment, the guide pointed at the light inside his helmet to indicate that it should be turned off. When his light went out, the guide on his left arm After a few clicks on the keyboard, the lights above the platform went out and it was pitch black.

Just when the tiger was a little panicked, an invisible light suddenly appeared directly in front of the platform. It was very small and very far away, and seemed to be on the mountain wall.

Tiger grabbed the fence and looked up. He didn't understand what the guide meant. The light made the blood in his body freeze. He hated the dark environment.

"People from here often come here." The guide stared blankly at the beam of light, "That is a hanging window, a one-meter square, which is aligned with the direction of the launch of our accelerator. There, we level the A mountain."

In the eyes of the tiger, the hanging window seemed to become smaller and smaller, and finally turned into a point.

The guide clasped his hands together as if praying, "We will eventually crack the secret of the beacon just like we leveled the mountain."

"can you?"

"meeting!"
