"Today, we're going to the opening ceremony of the Particle Collider." Sitting on the spaceship, Wang Dao hugged Yi Xiaoxiao next to him and said with a smile.

After three years of cultivation, Yi Xiaoxiao has become more and more impressive.

"What kind of particle collider? Is it worth it for you to attend the opening in person? Yi Xiaoxiao asked suspiciously.

She is a liberal arts student, and she doesn't care too much about these scientific things, and it's normal that she doesn't know.

The particle collider is a device developed on the basis of the high-energy synchrotron large particle collider, the main function is to accumulate and accelerate the flow of two particles injected by the pre-accelerator in succession, and make them collide when they reach a certain intensity and energy to produce a sufficiently high reaction energy.

The construction of this thing costs a lot of money, but its significance should not be underestimated, and it is of great significance to the scientific and technological progress and development of mankind.

"I'll give you a simple example, you've definitely heard of antimatter, right?"

Seeing that Yi Xiaoxiao was dizzy by professional terms, Wang Dao patiently changed his words.

"We can use the particle collider to find antimatter and how to synthesize it, and of course, that's just one of our main goals."

Antimatter is incredibly powerful, and the energy generated by the annihilation of matter in just a small amount of antimatter is comparable to that of a nuclear bomb with a yield of several million tons.

Because the conversion rate of the annihilation of matter and antimatter is 100%, which is dozens of times that of a nuclear bomb.

The replacement of fusion power by antimatter-powered spacecraft is the main goal of the next phase.

No matter how efficient nuclear fusion is, it is not as good as antimatter, and if it flies beyond the speed of light, it is counting on antimatter.

After chatting for a while, the two arrived at the construction site of the particle collider - the far side of the moon.

"Welcome Mr. Wang, Mrs. Wang!" Chief scientist Bai Xiang led a group of people and greeted him from afar.

Who said that scientists don't understand human feelings? Mrs. Wang screamed and Yi Xiaoxiao smiled.

Wang Dao and Yi Xiaoxiao are not married yet, but their relationship is very stable, like a couple of immortals, but they envy many people.

To say that these scientists, in order to fight for scientific research resources, throw away the festival and everything, this Mrs. Wang's cry is extremely natural.

Although there is a steady stream of resources in space, there are too many projects being carried out at the same time, first of all, the construction of spacecraft cannot be stopped, and the construction of various spaceport stations is also necessary.

There are countless other scientific activities, large and small, and a lot of resources and funds are needed everywhere, and although the particle collider is a key project, it is good to be able to win one more person and a dollar.

So Bai Xiang decisively took the lady route, after all, for men, the power of a twelve-level typhoon is not as powerful as the pillow wind.

Through the window of the science station, Yi Xiaoxiao was stunned by the scene in front of him, a ring that could not be seen at a glance, as if it was set on the moon, quietly staying in space.

"The Luna-1 collider is a standard ring with an acceleration channel twenty meters thick and a total length of 8,600 kilometers, which can theoretically accelerate particles to the speed of light!" Bai Xiang's pride is overflowing, full of pride and excitement.

At present, the largest particle collider is in Europe, with a total length of only 27 kilometers, which is not worth mentioning.

"Inside this accelerator, two streams of high-energy particles propagate forward infinitely close to the speed of light before colliding with each other.

The two streams of particles travel in opposite directions through different beam tubes, both of which are in a vacuum.

A strong magnetic field causes them to orbit around that acceleration ring, which is obtained using superconducting magnetics.

These superconducting magnetics are made using special cable wires, and they operate in a superconducting state, effectively conducting current with no resistance consumption or energy loss. ”

This is explained by Bai relative to Yi Xiaoxiao, no matter whether he can understand it or not, what should be explained still has to be said.

Wang Dao knows all about these theoretical things, but he didn't stop it, so let's just popularize science.

The Luna-1 particle collider was built on the far side of the moon to reduce construction costs and ease of maintenance.

In order to reduce the interference of other particles, most particle colliders are buried deep in the ground, using natural rock and soil to filter other particles.

However, no matter how thick the rock and soil is, it is impossible to exceed the thickness of the moon, and the entire moon is used as a filter layer, is there anything more perfect than this?

"The optimal working temperature of superconducting magnets is minus 271 °C, which is lower than liquid nitrogen.

Now it would be nice to be exposed directly to space, because the temperature of this space is already close to absolute zero because it is avoided by the sun's rays.

There must also be a vacuum in the pipe, that is, in space, we can obtain an environment of near absolute vacuum. ”

Wang Dao took over the task of explaining and said to Yi Xiaoxiao.

Absolute vacuum is impossible, matter is everywhere, there will always be all kinds of particles that we don't recognize, so we can't do anything.

Handing Yi Xiaoxiao an observation glass, Wang Dao pointed to the collider again, and continued: "Look at the transparent glass and those black squares on the outside of the pipe. ”

Because of the propagation nature of waves, even on the far side of the moon, a small amount of light waves from the sun will run into this area, although the amount is small, and it will interfere with the experiment.

There are also light waves and particles in other directions, which are almost ubiquitous, and there are two countermeasures to these unavoidable mischief.

The black square is a force field generator that uses the deflection effect of the force field to cause the uninvited particles to change direction and move away from the collision pipe.

Transparent glass is not ordinary glass, but a polymer organic material that can absorb all kinds of known particles and clean up uninvited guests who are unwilling to change direction.

With this double layer of protection, it is guaranteed that any known particles will not interfere with the test.

Although Yi Xiaoxiao was not interested in this, she could basically understand it, so she nodded in response.

"Husband, is the money to build such a particle collider enough to build a 100-million-ton spacecraft?"

Yi Xiaoxiao suddenly turned her head and replied to Wang Dao.

This thinking jumped too fast, so that the royal road of wisdom and demons was also stunned for a moment.

Pulling up Yi Xiaoxiao's soft wattle, Wang Dao smiled and replied uncertainly: "Probably yes, but science is priceless, as long as there is a need, then it must be made at any cost." ”

Saying that, Wang Dao also quickly calculated it in his heart, it's not okay, but he feels that his heart is dripping blood.

According to the purchasing power of the renminbi when Wang Dao first entered university, it would take almost 10 trillion yuan to build such a particle collider.

Well, it's not much, one-eighth of China's GDP that year.

After the system self-test, Wang Dao pressed the start button and launched this weapon to explore the microscopic universe.

The so-called ritual does not have many flower heads, and scientists do not pay attention to this.

Subsequently, Wang Dao stayed for another two days, discussed some related issues with the scientists, and then left the workstation with Yi Xiaoxiao.

The next time we come back, it's time for a big new discovery.
