China is building particle particles almost four times larger than the Large Hadron Collider (LHC) and is expected to produce more than a million Higgs Boson particles in the first decade of operations.
Plans for Circular Electronic Positron Collider (CEPC) – a 62 millimeters long coefficient – were first announced in 2012, a few months after the Higgs boson particles were detected at the LHC. Now researchers working on the project have published two new design reports to showcase what they have been doing over the past six years and what they are planning to do over the coming decades.
The report shows how the CEPC follows the LHC, which has a volume of just under 17 miles. It says that it can pass through the LHC capabilities in terms of physical experiments that can be performed – for 10 years, scientists say it will be able to produce a million Higgs bosons, 100 million V bosons and a trillion Z bosons.
Like the LHC, the CEPC is a circular shape. It will be located in an underground tunnel and consists of a linear accelerator, damping ring, acceleration, conveying lines and collisions. It will be a two-colored collider, with electronic and positronic sheaves circulating in the opposite directions in separate tubes.
The tunnel in which it is located can also be used to host the Proton Proton Collider (SppC) – which is currently under consideration. This "supercollider" would reach energy far beyond the LHC, LHC was designed to have a maximum amount of energy of 14 TeV, while SppC would work with a power of 70 TeV.
"The design concept report indicates that we have completed the basic design of accelerators, detectors and construction for the entire project," said Professor Gao Iuanning, chairman of the CEPC Institute, in a statement. "Our next step will focus on research and development of key technologies and prototypes for CEPC."
The design report was published at a ceremony held by the Institute of High Energy Physics (IHEP) in Beijing.
Geoffrey Tailor of the University of Melbourne, Chair of the International Committee for Future Accelerators (ICFA) and the Asian Committee for Future Accelerators (ACFA), said: "This is a significant milestone on the way to such an important object for basic physics. I do not doubt that the international community expects partnership in the development and work of CEPC and in the search for a better understanding of the basic components of matter. "
Over the next five years, scientists will conduct detailed research, construct prototypes of key technical components for CEPC. Collision infrastructure will also be built. It is expected that CEPC will begin in 2022 and will be completed in 2030.
If CEPC is successful, scientists hope that SpcC supercollider can function at some point in the 2030s. "As an energy border machine, SPPC could discover a whole new set of particles," the new report said. "The dark matter remains one of the most controversial problems in particle physics and cosmology. The poor interaction of solid particles (VIMPs) remains the most reliable candidates for dark matter." SppC, according to researchers, can be used to "significantly expand" the search for VIMPs, has, potentially providing answers to one of the greatest mysteries in space.
