Chapter 413 An Intern Not an Intern
Chapter 413 An Intern Not an Intern
As one of the major national laboratories of the Department of Energy, SLAC has very strict security guards.
Chen Zhou felt that if he didn't have a work permit or someone led him.
Even if you are a student at Stanford University, it is estimated that it will be difficult to get in.
After going through a series of security checks, Chen Zhou followed Friedman and others, and finally stepped into the territory of SLAC.
Compared with Yanjing National Laboratory for Molecular Sciences in Huaguo, SLAC is obviously more legendary.
Earlier in 1962, construction began on the Linear High Energy Electron Accelerator, in the hills west of Stanford University.
This project is called "M project", M stands for "monster", that is, Monster.
Later, this monster continued to show its "power".
Quarks, charm quarks and anti-charm quarks are all found here.
As a result, many Nobel Prize winners were born here.
In addition, there are more experimental devices here.
In addition to the linear high-energy electron accelerator, there are electron-positron accelerator rings, synchrotron radiation light sources, electron-positron colliders and linear colliders, etc.
Most importantly, here is the first international network of Beimi.
It was also SLAC's first website to show physicists the potential of the web.
People in the particle physics community have easier access to very busy databases of the scientific literature.
However, SLAC also went through a midlife crisis.
In 2008, the collider's large detector, the SLD, was shut down for storage.
Soaring land prices and construction costs in the San Francisco Bay Area have made it impossible to build a next-generation linear collider.
At the same time, the world's research center for high-energy particles was also transferred from the United States to CERN near Geneva, Switzerland.
That is CERN, which has the largest particle physics laboratory in the world.
At that time, many people wondered whether SLAC could survive without a large collider?
But the result is that SLAC is still alive and well until today.
However, SLAC has gradually transformed from high-energy particle physics to a high-intensity X-ray research center.
This can be regarded as a survival change.
The destination of Chen Zhou's trip is the PEP laboratory.
That is the Electron Positron Collider Laboratory.
This is the collider that started construction in 1980.
The reason for the construction is that the energy of the electron-positron accelerator ring is too small.
The ring diameter of SLAC's positron-electron accelerator ring is only 73 meters, and the energy achieved is limited, and the number of particles produced by collisions is limited.
And the storage ring of PEP is equivalent to 10 times that of the electron-positron acceleration ring!
The number of positron-electron collisions is several times that of the positron-electron accelerator ring!
It's just that the results of PEP are not as brilliant as the electron-positron acceleration ring.
Electron-positron accelerator ring is the accelerator where the charm quark composed of quark and anti-quark is discovered.
For this reason, Burton Richter, who discovered the charm quark, won the Nobel Prize in Physics.
After that, Martin Lewis Pell also used the positron-electron accelerator ring to do physical experiments, and discovered a new particle called tau lepton produced after the positron-electron collision.
Also won the Nobel Prize in Physics.
Therefore, as the successor of the positron-electron accelerator ring, or in other words, the more hopeful one.
PEP does not yet have the results comparable to Big Brother.
However, the staff of SLAC did not give up.
This is also the meaning of this project that Friedman brought Chen Zhou to participate in.
Once the "gumball" is discovered, it must be another Nobel Prize achievement!
Since Chen Zhou entered the laboratory, he followed Friedman obediently.
It's not that I'm afraid of anything, it's just before Friedman arranges work for himself.
Chen Zhou felt that he only needed to watch more, listen more, do less and talk less, and he was fine.
As for Matheson and Coyle, they were arranged by Friedman to leave after stepping into the laboratory.
These two people are old acquaintances in the laboratory, and they are quite familiar with the road.
Listening to the conversation between Friedman and a previous researcher, Chen Zhou also roughly understood.
Friedman is one of the leaders of this project.
There was another one that Chen Zhou hadn't seen yet.
At this time, Friedman turned around and pointed to Chen Zhou, and said to the researcher, "This is my new graduate student, and I plan to hand him over to you."
The researcher froze for a moment, then nodded, "Okay, Professor Friedman."
Friedman said to Chen Zhou again: "This is Professor Cross. From now on, you will follow him to get familiar with the laboratory."
"Okay, Professor Friedman." Chen Zhou's answer was the same as that of Professor Cross.
Friedman left after giving his orders.
For the upcoming experiment, he still has a lot to confirm.
Therefore, it is most suitable to hand over Chen Zhou to others.
Chen Zhou glanced at the bearded Professor Cross, who smiled at him.
Chen Zhou asked, "Professor Cross, where do we start?"
Professor Cross said: "Let me show you around the PEP laboratory first."
After speaking, Cross took Chen Zhou to wander around the PEP laboratory.
Simply put, PEP is an experimental device with a ring at one end and a rod at the other end.
But the area occupied by this thing is not small.
After all, in order to accelerate particles of any kind to extremely high energies, their orbits must be of sufficient length.
Cross was more interested in Chen Zhou than taking Chen Zhou to visit PEP's experimental device.
This was the first time he met Professor Friedman, bringing a graduate student from Huaguo with him.
Not to mention, Friedman brought this Chinese student here.
After introducing some of the experimental devices in front of him, Cross asked Chen Zhou curiously: "Speaking of which, 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: "A week, if you count from the first meeting."
Cross looked at Chen Zhou in surprise.
He thought it was a student who had been with Friedman for a long time, but he didn't expect that he was a pure freshman.
How did Friedman bring him here?
When Cross was stunned, Chen Zhou said, "Professor Cross, let's go to the next location."
"Oh, good." Cross came back home and wanted to ask more questions, but he always felt that it was not appropriate for him to ask.
While introducing the experimental device to Chen Zhou, he touched Chen Zhou's bottom through small talk.
Through Cross's question, Chen Zhou also roughly understood what the other party was thinking.
But Chen Zhou did not hide from the other party, and told Cross truthfully.
For this information, Cross can ask Matheson, Coyle, or even Friedman.
But what Chen Zhou thought was nothing, but to Cross's ears, he just found it incredible.
He couldn't understand such a person from Hua, a student who graduated from Yenching University in Hua.
Even outstanding graduates with a double major in the Department of Mathematics and the Department of Physics have achieved such impressive results in mathematics.
But this is physics, this is the field of high-energy physics, the laboratory of electron-positron colliders.
He didn't understand what Friedman meant.
At least in his opinion, Chen Zhou should be qualified to come here after being polished by the school laboratory and laying a solid foundation, right?
Otherwise, who would dare to let him participate in the project?
After getting acquainted with the PEP experimental device with Cross, Chen Zhou asked, "Professor Cross, what should I do next?"
Hearing this question, Cross froze for a moment.
Regarding Chen Zhou, he felt that no matter how many guesses there were.
This is still just a graduate student who has just entered school.
In the absence of special arrangements by Friedman, probably this kid can only be used as an intern who is not an intern.
"An intern who is not an intern?" Chen Zhou was a little puzzled when he heard the words that Cross did not shy away from.
There are only two updates today. I have encountered something recently and the state is very bad. Sorry!
