China Aims to Build World's Largest Particle Accelerator

TapTechNews June 28 news, according to the report on the website of the British weekly 'Nature' on June 17, China hopes to start building the world's largest particle accelerator within three years, taking a step ahead of the large accelerator proposed by Europe.

The report said that the proposal of China's CEPC (Circular Electron Positron Collider project) is expected to be submitted next year and may be included in China's next five-year plan.

According to a comprehensive technical design report released on June 3, if the project can get government support, it may start construction in 2027 and take about 10 years to build. The report estimated that this super-large accelerator will cost 36.4 billion Chinese yuan (about 5.2 billion US dollars), and the construction and operation costs are much lower than the 17 billion US dollars of the Future Circular Collider (FCC) proposed by Europe. If approved, the construction work of the FCC will begin in the 2030s.

This latest report contains a detailed blueprint of the accelerator layout design and prototype components, said Wang Yifang, director of the Institute of High Energy Physics of the Chinese Academy of Sciences. TapTechNews noted that the report also evaluated three possible locations: Qinhuangdao, Changsha and Huzhou. Wang Yifang said: 'We now believe that this is a facility that we can actually build.'

This technical design report proves that China has the ability to complete the construction of the CEPC accelerator basically without the participation of international researchers, said Cohen, a member of the CEPC International Advisory Committee, 'As long as they want to build this accelerator and take action, they can build it.' But he also said that China may need external expert forces to develop the detector equipment of this collider, which is not in the discussion scope of this report.

However, Wang Yifang believes that the CEPC will be a global cooperation. He pointed out that international researchers have accounted for 30%-50% in the working teams of some large-scale physical facilities in China - including the Jiangmen Neutrino Experiment in Kaiping which is planned to be put into use this year. He said: 'We believe that the CEPC will be about the same.'
