BEIJING, China – The Chinese Institute of High Energy Physics has unveiled the project of a 100-kilometer particle accelerator that could be an attempt to lead the field of particle physics.
Earlier, the Chinese tried to build a 50-kilometer accelerator, however, eventually designing a 100-kilometer ring.
The underground facility will be in a Higgs boson factory, called “particle of God.” The Chinese main objective is to demonstrate the existence of new physics and solve the mystery of dark matter.
The Circular Electronic Positron Collider (CEPC) will consist of three installations located in a tunnel, in addition, in a circular ring will be the accelerated phases of particles originated in a linear accelerator. With this, the electron and positron groups will be accumulated in their respective rings, assembling in phases and colliding.
The project will have two moments of interaction between electron and positron phases, where detectors will be installed to record the physical processes.
In order to achieve the desired luminosity, the particle beam must be very dense, maintaining and focusing with strong magnetic fields, but this is not enough, ie it is necessary that the opposite phases collide with the angle and be tightened in a thinner place. To do this, the Chinese used the “crab waist” technology, created jointly by Russian and Italian physicists.
According to Mikhail Zobov, one of the creators of the technology and manager of technological research at the National Laboratory of Nuclear Physics in Italy, the crab waist practically solved the main problem of the non-linear interaction of the phases of charged particles in the collision.
The expert said that he used several works of Soviet and Russian researchers as a reference to develop the project, however, he says that to find the full potential it is necessary to solve some problems, as well as to obtain technical solutions.
One of the issues to be solved is to ensure the stability of the minor phases and high intensity of charged particles.
Experts expect to get one million Higgs boson births in ten years, and they say the project is optimized to use its 100-kilometer tunnel to house the Proton supercolumn from 2040.
However, the project does not appeal to everyone, as is the case of Chinese physicist Chen Ning Yang, a Nobel laureate. The physicist criticized the project because of its high cost.
In addition, there are those who question the safety of the future of science, since the construction of the Large Hadron Collider (LHC) was covered by a cloud of uncertainties regarding high levels of radiation, the creation of black holes and supposedly explosions capable of destroying the planet.
According to estimates, the Chinese accelerator will cost almost $5 billion and its construction is planned for the period between 2022 and 2030.
