China Building 62-Mile-Long "supercollider" to produce a million Higgs Boson



China has been developing a particle pool that is almost four times larger than the LHC and is expected to produce more than one million Higga basin particles during the first decade of operation.

Plans for a circular electron positron colibilizer (CEPC), a 62-mile-long colleague, were first announced in 2012, a few months after the LHC found the Higg boson particle. Now, researchers working on the project have released two new design reports to showcase what they have been working on in the last six years and what they plan to do in the coming decades.

The report shows that the CEPC lacks the LHC, which is only below 17 miles. It outlines how it can exceed the capacity of the LHC in the field of physical experiments that can be done – over 10 years, scientists say they will be able to produce one million Higgs bosons, 100 million W bosons and trillions Z booms.

Like the LHC, the CEPC is a circular shape. It will be located in an underground tunnel and consists of a linear accelerator, a shock absorber ring, an amplifier, transport lines and a collider. It will be a double ring collider, with electron and positron beams, circulating in opposite directions in separate tubes.

The cell in which it is located can be used to capture a super proton proton collier (SppC) – the proposal is under consideration. This "supercollider" could reach an energy level higher than the LHC – the LHC was designed to have a maximum collision energy of 14 TeV, while SppC will work with 70 TeV.

"The conceptual report of the project shows that we have completed the basic design of the accelerator, detector and engineering system for the whole project," said Gao Yuanning, Chair of the CEPC's Institutional Board, Professor Gao Yuanning. "Our next step will be to focus on the research and development of CEPC's core technologies and prototypes."

The design signature was announced at a ceremony organized by the Beijing Institute of Higher Education Physics (IHEP).

Geoffrey Taylor, Chairman of the International Future Accelerators Committee (ICFA) of Melbourne, and the ACFA, said: "This is an important milestone on the way to such an important basic machine tool. I have no doubt that the international community is looking forward to a partnership in the development and operation of the CEPC and in an effort to better understand the core components of the issue. "

In the next five years, scientists will conduct large-scale research, creating prototype CEPC's core technical components. The collision infrastructure will also be built. CEPC is expected to start construction in 2022 and will be completed in 2030.

If the CEPC proves to be successful, scientists are hoping that the SppC supercollider could work at some point in the 2030s. "As the energy limit, the SPPC could detect a whole new set of particles," says a new report. "Dark matter is still one of the most affluent issues in particle physics and cosmology. Strongly interacting massive particles (WIMPs) are still the most likely candidates for dark matter." According to researchers, SppC could be used to "substantially expand" the WIMP search query, possibly giving answers to one of the greatest secrets of the universe.
