China plans world’s largest supercollider
Beijing, China – Chinese scientists are racing to complete plans for a supergiant particle collider that, when built, will dwarf every other accelerator on the planet.
The underground particle-smashing ring aims to be at least twice the size of the globe’s current leading collider – the Large Hadron Collider (CERN) outside Geneva. With a circumference of 80 kilometres, the Chinese accelerator complex would encircle the entire island of Manhattan.

… the construction of the electron accelerator and then the more powerful proton collider.
Within the same 80km tunnel, the collider complex plans to be divided between two different super colliders. The Circular Electron Positron Collider (CEPC) smashes together electrons and anti-electrons, while the Super Proton Proton Collider (SPPC) will be used to study the super-speed collisions of protons. The CEPC is designed to study with precision the Higgs boson and how it decays following a collision. The SPPC might uncover a new range of particles beyond those already known.

This is superb. I went along to the conference on high energy physics where the Higgs Boson was announced, and the plans laid out there for future colliders were quite modest, involving either enhancement of the existing Large Hadron Collider or the building of smaller devices that would operate at lower energy but at higher intensity.
With the formal discovery of the Higgs, and the rejection of supersymmetry, the explanation of neutrino mass, and the rejection of large miniature black holes (due to large string roll-up dimensions) and other exotic particles, the next hurdle in high energy physics is dark matter. This new proposal should help a lot.
