China aims to start construction of its Circular Electron-Positron Collider (CEPC) in 2027, aligning with the country’s 15th five-year plan, according to a recently unveiled design report on the project.

According to the Global Times, CEPC is a circular Higgs factory proposed by the Chinese particle physics community in 2012. The project, to be hosted in China in a circular underground tunnel of approximately 100 kilometers in circumference, is a double-ring collider with electron and positron beams circulated in opposite directions in separate beam pipes, and the detectors are installed at two interaction points.

It represents a crucial component of the global strategic plan for high energy physics. Once completed, it will foster collaboration among scientists worldwide and drive advancements in the understanding of the fundamental nature of matter, energy, and the universe, read a technical design report (TDR) on the project released on 3rd June.

According to the TDR, the CEPC team hopes to present the C
EPC proposal (including accelerator, detector and engineering) for selection by the Chinese government around 2025. The construction of the CEPC is set to commence around 2027 and is projected to span 8 years, reaching completion by 2035.
