The Circular Electron Positron Collider (CEPC) is a proposed Chinese electron positron collider for experimenting on the Higgs boson. It would be the world's largest particle accelerator with a circumference of 100 kilometres (62 mi).[1]
CEPC was proposed by the Chinese Academy of Sciences' Institute of High Energy Physics in 2012.[2][1] Projections in 2023 were for a proposal to be submitted to the government in 2025, and construction taking place from 2027 to 2035; the projected cost was CN¥36.4 billion, including experiments.[3]
The design was produced by a team of international physicists.[1] The technical design report was released in December 2023.[3]
