Chapter 504 CEPC
Jiuquan Satellite Launch Center.
More than 100 scientists watched the launch of the Xinyuan-3 rocket here, and the 50-meter-long fairing made the rocket look very tall, in sharp contrast to the vast Gobi Desert.
The staff of the launch center who followed Penrose and others said:
"This is the ninth module of the Qianqian space station, codenamed 'Shen Monkey', which is a module used to provide electricity and carry scientific facilities, and cannot provide long-term survival conditions for astronauts."
The naming of the 12 cabins was also decided by the Aviation Development Commission on the eve of the completion of the Advance, which directly corresponds to the 12 zodiac signs, the first six zodiac signs are the living cabin, and the last six are the service cabins.
A group of foreigners took a long time to understand that they were still in the clouds, but they still expressed their praise.
After all, you are the only one in the world who can make this kind of giant pod in large quantities, even if it is named after a pet.
The liquid oxygen and kerosene engine used in the Xinyuan-3 rocket is much larger than that of the Saturn V, which made the scientists present addicted.
Just when the rocket was left with only a small spot in the sky, a deafening sound sounded in the sky again.
Stephen Hawking: "Roger, are there rockets again?" ”
Penrose looked up for a long time, then spotted a white object approaching at high speed against the background of a clear blue sky.
"No, it's an airplane, and I think it's a supersonic plane."
Ten minutes later, Penrose and others, who were being entertained at the launch center, saw several people striding towards them.
The man at the head was a little thin, and he walked straight up to Penrose and stretched out his hand to introduce himself:
"Ye Changsi, vice president of Xinyuan, also has research on physics."
The man who followed him followed:
"Cheng Nankai, gentlemen, we have a common purpose."
……
Beijing, the center of the capital's positron and negative electron collider.
The Positron and Negative Electron Collider (BEPC) was built in 1990 and is already one of the world's eight high-energy accelerator centers.
There are two types of particle accelerators, linear accelerators and cyclotrons, which can be subdivided according to the research field at the time of design.
However, in general, particle accelerators can be modified to adapt to different test goals, so the life of a high-energy accelerator can still be used for a long time.
The BEPC is a linear accelerator that has undergone several upgrades since its completion, the most recent of which was started in 2006 and completed in 2009, increasing the energy level of a specialized field by a factor of 10.
Wu Yunfeng is the director of the Institute of High Energy Physics of the Academy of Sciences and the deputy director of BEPC.
But BEPC is behind the times, and it was designed with limited potential as a linear electron accelerator, just over 200 meters long.
The LHC not only has a length of 27 kilometers, but also a more expensive and versatile proton accelerator, and the total cost of BEPC is only 280 million yuan, which is less than a fraction of the LHC.
The Institute realized that domestic accelerators were far from meeting the demand, so it proposed the CEPC (Annular Positron Collider) plan, which is expected to invest about 27 billion yuan to build a 100-kilometer-long toroidal electron accelerator.
The reason why it is not a proton collider is because of the cost as well as the prospect, but more often than not.
Although the LHC, which Europe has spent a lot of effort to manufacture, has made great achievements in recent years, and in 2012 discovered the Higgs boson, which is known as the "God particle", it can only stop there, and it is difficult to conduct further research.
If a new type of proton collider is to be built that is larger than the LHC and can meet the expectations of scientists, the cost will inevitably soar again, and the final consensus of the Institute is that if the ultra-high energy level cannot be achieved in one step, then there is no point in building a new proton accelerator.
So in the end, they chose to plan CEPC, the world's largest and most advanced electron accelerator, but this project has been discussed for five years and still has no intention of starting a project.
It is not that the state cannot afford to pay for it, but it is difficult to convince the upper and lower collectives under the current circumstances.
It's still 2017, only seven years after GDP caught up with the island countries, and last year it was 59% of Aramco.
The current hope of the institute is to be able to launch it in 2020 and then build a new accelerator around 2030.
Wu Yunfeng is planning a scientific exchange meeting between the Academy of Sciences and the Belt Clan, and there are many high-energy physicists who have come over this time, and there are even important leading members of the LHC, so it would be very beneficial if he could take the opportunity to obtain some of the latest results of the LHC.
"Old Wu, Old Wu!"
Wu Yunfeng looked at the panicked Li Shi in surprise, the latter was calling his name before he entered the door, and after coming in, he couldn't wait to say without getting angry:
"Let's go, go to United Mining, there's something big."
"What's the big deal?"
"Accelerator, this time those experts from the country proposed that we build a high-energy proton accelerator, and someone from the Academy of Sciences also made a report, and even Xinyuan Company intends to support and contribute!"
Although he was still confused, Wu Yunfeng still followed Li Shi to the headquarters of United Mining, and the scientists who returned from Jiuquan chose to hold a meeting there.
On the way to the car, Wu Yunfeng learned the whole story from Li Shi:
It turned out that the proposal made by the Penrose trio three days ago was jointly submitted by Lin Ju and Academician She, and then several academicians who were close to the Aviation Development Commission, as well as experts from the nuclear base of Xinyuan Company, got together.
Yesterday, I asked foreign scientists to organize researchers who need particle accelerators in China to do research for a few days.
Yesterday his superiors flew to Vienna for a meeting on the outer space treaty, hoping to get a more definite answer before he returns.
The Academy of Sciences immediately deliberated on the matter overnight, and in the end, those who agreed overwhelmingly reached a collective consensus: to push the superparticle accelerator as much as possible.
The team of experts with him has a limited stay time, and the domestic experts in Hui and Hubei provinces were rushing back last night.
But the most surprising thing is that Xinyuan Company actually intervened, Li Shi didn't know where he heard the gossip, and their two vice presidents persuaded Lin Ju to take out 10 billion funds to support the construction of the accelerator in three years, which is amazing.
10 billion funds, province and province in the country he has the confidence to build another LHC, when is a private company willing to be this kind of wrongdoer?
