CERN unveils proposal to build new bigger and more powerful particle accelerator.

The Future Circular Collider (FCC) is a proposed particle accelerator in Geneva, with a circumference of about 100 kilometers, nearly four times larger than the Large Hadron Collider (LHC). The design and construction are expected to take 20 years, with the project being built in phases. Initially, it will collide electrons and positrons, followed by electrons and lead nuclei. By 2050, the FCC aims to achieve proton-proton collisions at 100 TeV, seven times the LHC's capacity. The FCC will include advanced components like a radiofrequency acceleration system, cryogenic plants, and high-field magnets.

What types of particles will the FCC collide in its early stages?
