Chinese scientists presented in Beijing their detailed plans and the progress they have made so far to create the largest particle accelerator that will have size and capabilities beyond those of the current CERN accelerator.
It is the Circular Electron Positron Collider (CEPC), the construction of which is expected to begin in 2022 and will be completed by 2030. The accelerator will be in a 100 km underground tunnel (compared to 27 km of the CERN), where electron and positron rays will move from opposite directions.
In the future, once the CEPC has been in operation for decades, it will be possible to upgrade to a Super Proton Proton Collider-SppC, which will reach up to 70 TeV versus 14 TeVs from CERN.
Meanwhile, during the first decade (2030-2040), it is expected that the CEPC will produce over one million Higgs bosons, one hundred million W bosons and nearly one trillion Z bosons (W and Z are carriers of the so-called patient strength). Also, by decaying the B buses, billions of quarks of different species will be produced.
The original idea was introduced to the international community in 2012, and thousands of Chinese physicists and engineers have worked together with their foreign colleagues to present it in detail at an event at the Institute of High Energy Physics (IHEP) of the Chinese capital .
“Physicists from many countries will work together to explore the frontiers of science and technology, bringing to a new level our understanding of the fundamental nature of matter, energy and the universe,” said Professor Wang Jiang, director of IHEP and head of the Steering Committee for the construction of the new accelerator.
