As one of the main national laboratories of the Ministry of Energy, Slac has very strict security guards.

Chen Zhou felt that if it weren’t for having a work permit or someone led it.

Even students from Stanford University will probably be difficult to get in.

After a series of security checks, Chen Zhou followed Friedman and others and finally stepped into Slac's territory.

Compared with the Yanjing National Laboratory of Molecular Science in China, Slac is obviously more legendary.

Earlier in 1962, construction of a linear high-energy electronic accelerator started in the hills of Stanford University.

This project is called "m project", and m means "monster", which is also monster.

Later, the monster kept showing its "power".

Quarks, charm quarks and anti-charm quarks are all discovered here.

Therefore, many Nobel Prize winners were born here.

In addition, more experimental devices here have also become.

In addition to linear high-energy electronic accelerator, there are also positive and negative electron acceleration rings, synchronous radiation light sources, positive and negative electron colliders and linear colliders, etc.

Most importantly, there is Beimi’s first international network here.

It is also the first Slac to show physicists the potential of the network through its website.

People in particle physics can more easily access very busy scientific literature databases.

However, Slac also experienced a midlife crisis.

In 2008, the collider's large detector SLD was shut down and stored.

The high land prices and construction costs in the San Francisco Bay Area have made it impossible to build the next-generation linear collider.

At the same time, the World High Energy Particle Research Center has also been transferred from the United States to the European Nuclear Research Center near Geneva, Switzerland.

That is, it owns the world's largest particle physics laboratory.

At that time, many people suspected that the Slac without the Large Collider could exist?

But the result is that Slac is still alive today.

However, Slac has gradually transformed from high-energy particle physics to a high-intensity x-ray research center.

This is also a transformation to survive.

The destination of Chen Zhou and his team's trip is Pep Laboratory.

That is, the positive and negative electron collider laboratory.

This is a collider that began construction in 1980.

The reason for construction is that the energy of the positive and negative electron acceleration ring is too small.

The ring diameter of the positive and negative electron acceleration ring of slac is only 73 meters, the energy achieved is limited, and the number of particles generated by the collision is limited.

The storage ring of pep is 10 times that of positive and negative electron acceleration ring!

The number of positive and negative electron collisions is several times that of positive and negative electron acceleration rings!

However, Pep's results are not as brilliant as positive and negative electronic acceleration rings.

The positive and negative electron acceleration ring is an accelerator that discovers charm quarks composed of quarks and antiquarks.

Therefore, Burton Richter, who discovered the charm quark, won the Nobel Prize in Physics.

After that, Martin Lewis Pell also used positive and negative electron acceleration rings to perform physical experiments and discovered a new particle called lepton produced after positive and negative electrons collided.

He also won the Nobel Prize in Physics.

Therefore, as the successor, or more hopeful, of the positive and negative electron acceleration ring.

Pep is indeed not comparable to Big Brother.

However, the slac staff did not give up.

This is also the significance of this topic that Friedman brought Chen Zhou to participate in.

Once the "glue ball" is discovered, it will inevitably be another Nobel Prize-level achievement!

Since Chen Zhou entered the laboratory, he has followed Friedman honestly.

It's not that I'm afraid of anything, but before Friedman arranges work for himself.

Chen Zhou felt that he just needed to watch more and listen more, do less and speak less, and that would be OK.

As for McSyson and Coyle, they were arranged to leave by Friedman after entering the laboratory.

These two people are old acquaintances in the laboratory and are quite familiar with each other.

Listening to the conversation between Friedman and a researcher ahead, Chen Zhou also roughly understood.

Friedman is one of the people in charge of this topic.

There is another one, Chen Zhou, who has not seen yet.

At this time, Friedman turned around and pointed at Chen Zhou, and said to the researcher: "This is my new graduate student, and I plan to hand him over to you."

The researcher was stunned for a moment, then nodded: "Okay, Professor Friedman."

Friedman said to Chen Zhou again: "This is Professor Cross. From now on, you can follow him to get familiar with the laboratory."

"Okay, Professor Friedman." Chen Zhou's answer was the same as Professor Cross.

After Friedman gave the order, he walked away.

He still has many things to confirm for the upcoming experiment.

Therefore, it is most suitable to give Chen Zhou to others.

Chen Zhou glanced at Professor Cross with a big beard, and the other party smiled at him.

Chen Zhou asked: "Professor Cross, where do we start?"

Professor Cross said: "I'll take you to visit the Pep Laboratory first."

After saying that, Cross took Chen Zhou to stroll around in the Pep Laboratory.

Simply put, pep is an experimental device where one end is a ring and the other end is a root rod.

But the area of ​​this thing is large.

After all, to accelerate various particles to extremely high energy, their orbits must reach sufficient length.

Compared to taking Chen Zhou to visit the experimental device of Pep, Kroos is more interested in Chen Zhou.

This was the first time he met Professor Friedman and brought a Chinese graduate student.

Not to mention, Friedman also brought this Chinese student here.

After introducing some of the experimental devices in front of him, Kros asked Chen Zhou curiously: "Talk about it, are you a new graduate student this year?"

Chen Zhou nodded: "Yes, I just came to MIT to enroll."

Cross asked again: "How long have you been in contact with Professor Friedman?"

Chen Zhou replied: "It's about one week, if we count from the first meeting."

Cross glanced at Chen Zhou in surprise.

He thought this was a student who had already had a relationship with Friedman, but he didn't expect that he was a pure freshman who had just entered school.

Then how could Friedman bring him here?

While Cross was stunned, Chen Zhou said, "Professor Cross, let's go to the next location."

"Oh, OK." Cross came back to his country and wanted to ask something more, but he always felt that it was not appropriate to ask like this.

While introducing the experimental device to Chen Zhou, he touched Chen Zhou's bottom through chatting.

Through Cross's question, Chen Zhou also roughly understood what the other party was thinking.

But Chen Zhou did not hide it from the other party and told Cross truthfully.

Cross can ask about this information by just looking for Madsyson, Coyle, or even Friedman.

But Chen Zhou thought there was no information, but when he heard it, he felt it was incredible.

He couldn't understand that such a Chinese person was a student who graduated from Yanjing University in China.

Even outstanding graduates from the Department of Mathematics and Physics have achieved such impressive results in mathematics.

But this is physics, this is the field of high-energy physics, and it is the laboratory of the positive and negative electron collider.

He didn't understand what Friedman meant.

At least in his opinion, Chen Zhou should have been polished by the school laboratory and laid a solid foundation before he was qualified to come here, right?

Otherwise, who dares to let him participate in the project?

After following Cross briefly got to know Pep's experimental device, Chen Zhou asked: "Professor Cross, what should I do next?"

Upon hearing this question, Cross was stunned.

Regarding Chen Zhou, he felt that no matter how many speculations there were.

This is always just a graduate student who has just entered the school.

When Friedman did not have special arrangements, this kid could only be used as an intern who was not considered an intern.
