“The collider will have a circumference of 100 kilometers, with a center-mass energy up to 240 giga electron-volts both setting a world record,” Wang said. The collider should produce more Higgs boson particles, the essential, inevitable quarry of modern particle physics, He noted.

The conceptual design for the Circular Electron Positron Collider (CEPC) passed international examinations in September, Wang said.

The collider will provide light at a million electron-volt power level, creating the most advanced conditions for research on new materials and nuclear physics.

Scientists from the U.S., Europe and Japan have participated in designing the project, will work on the building process and conduct research with the collider.

In a bid to maximize the project’s service life, scientists are mulling upgrading the electron positron collider around 2040 into a proton collider.

By then, the center-mass energy for the CEPC will have reached about 100 tera electron-volts, seven times as powerful as the Large Hadron Collider (LHC) in Switzerland.

The Large Hadron Collider is being upgraded to 14 TeV collision energy in 2018.
