Chapter 223: The Underworld (Supplement 2/39)
"Can I take pictures here?" After receiving an affirmative answer, Liu Yuzhou picked up the camera hanging around his neck again and took pictures of this sign.
With the words "where-the-web-was-born" written on it, it was clear that this humble office was the birthplace of the Internet, which revolutionized the world and changed the lives of people all over the world.
"Its server is in the same exhibition hall you just saw, and it says in red ink: 'This machine is a server, please don't turn it off!'" Dr. Voss was surprised by this, and almost every visitor to CERN would stop by to take a picture and then send it to the Internet created by Tim Berners Lee.
"Isn't this the Center for Nuclear Physics, and you're still studying these things that seem to have nothing to do with physics?" asked Liu Yuzhou.
"The original purpose of the Internet was to provide a fast and convenient way for laboratories around the world to communicate, but Tim probably didn't expect it to have such a big impact!" Seeing that the filming was completed, Dr. Voss led them on, "and promoting the development of new technologies is also an important function of CERN." ”
As he passed by another office, he pointed inside, "The team here invented touchscreen technology for accelerator control systems, and then people found it more convenient to use a mouse and abandoned it, but now we are approached by many mobile phone developers looking to buy this technology, and it may not be long before you can use touchscreen phones!"
, I didn't expect this thing to be developed by you too! Lu Qiujian looked at the office, how many young people's waists have you guys cut off!
Glancing twice, Dr. Voss continued to move forward, "Research is underway to treat cancer with high-energy protons and other heavy ion beams, and if successful, CERN will once again bring good news to all mankind!"
Well, just now I cut my waist, and now I'm curing my broken waist. CERN still provides a full set of services! Lu Qiujian secretly complained.
Coming out of the R&D center, Dr. Voss shrugged apologetically at Liu Yuzhou, "It seems that your journey is coming to an end here, and the rest of the place is probably only for Lu and his classmates to enter!"
"Tsk, that's a pity!" Liu Yuzhou was reluctant to look at other buildings in his sight that he hadn't entered, "Then I'll go back to the hotel first, and you can continue to visit!"
After arranging for the staff to take him out, Dr. Voss, Lu Qiujian and others came to the entrance of the ATLAS probe, which is the code name of the largest probe hyper-torus instrument on the LHC;
After a series of complicated procedures such as iris verification and testing, Lu Qiujian calmed down and stepped into the elevator with excitement.
After a one-minute descent, the elevator comes to the platform area 90 meters underground. FROM HERE, THE ATLAS COULD BE SEEN IN ITS ENTIRETY, AND DR. VOSS TOOK OUT A RADIOMETER AND LED THEM OUT AFTER MAKING SURE THERE WERE NO PROBLEMS.
"Wow!" Dietrich, who had come here for the first time like Lu Qiujian, couldn't help but exclaim, only to see a metal structure circular surface radiating from all sides with an extremely thick blue pillar as the center, and the circular surface was covered with dense reflective plates made of unknown materials, which seemed to be the ATLAS detector.
"It is 46 meters long, 25 meters in diameter and weighs 7,000 tons. It's the same weight as the Eiffel Tower!" Dr. Voss proudly introduced, "The reason why it was named Hercules (ATLAS in Greek mythology is a titanic god who supports the sky on his shoulders) is to use its unparalleled power to discover tiny particles that other instruments are not happy to find!"
Well, the power is greater, and even smaller particles can be observed? What kind of logic is this? To use the metaphor of Greek mythology, it seems more appropriate to use the hundred-eyed giant Argos or Thea, the goddess of light and sight?
"ATLAS can take 40 million photos per second. Dr. Voss continued to introduce them to the big guy with great interest. "Only about 500 of them collided head-to-head and were read out for analysis. ”
Those who collide head-to-head will create a microscopic Big Bang, recreating the state of the universe 1 microsecond after the Big Bang. Well, one second equals a thousand milliseconds. One millisecond equals one thousand microseconds, which is a short time.
The work done by Lu Qiujian, Dietrich and others some time ago can be said to be to find out the 500 useful ones from the 40 million photographs in each piece, and then discover new things from these 500 photos.
One can imagine how tedious and long the process is. It can also explain why the work done by Lu Qiujian some time ago brought so much stimulation to Higgs; if Higgs is compared to a capitalist, then Lu Qiujian's new method can make his factory produce twice as much product in the same time, and the capitalist will be so excited when he hears it!
"Alright, let's get to see the other big guy!" Dr. Voss then led them to the Compact Muon Coil, another important detector for the LHC.
"Gentlemen, you are now in the territory of the French Republic! If you do so from the ground, you will probably have to go through some formalities!" said Dr. Voss, joking.
The CMS detector is a cylindrical structure about 21 meters long and 16 meters in diameter, weighing 12,500 tons, located in an underground cavern in the French town of Cessy, which is why Dr. Voss made such a joke.
Well, if you go straight up from here, it will come out of the backyard of Yang Xilan, the former star captain of the Chinese women's volleyball team, and it is said that her villa is in this town.
"The operating conditions of the cooling system, power system, underground air system and other systems will be fed back here!" Dr. Voss asked them to observe the inside of the monitoring room through the glass, and the walls inside were densely covered with monitors, which felt very sci-fi!
With such a large base, Switzerland alone cannot provide enough electricity from the power grid, so France has also taken on the task of supplying CERN with a part of the energy supply, and the power quota has to be negotiated with the two countries at the beginning of the experiment, which shows the investment required for the high-energy physics experiment.
Only a few large countries or international cooperation organizations are capable of accomplishing this feat, and private companies basically don't have to think about it! Otherwise, energy alone will give them a headache. (To be continued.) )
