Cern plans even larger hadron collider for physics search - BBC News
Currently called the Future Circular Collider (FCC), it will be built in CERN's Geneva site along with the Large Hadron Collider and its predecessors, it will have four times the LHC's size and accelerate particles to ten times the LHC's energy. An electron-positron version may go online in 2040 and a proton version in the 2050's.

Future Circular Collider Study FCC publishes concept design for a post-LHC future circular collider at CERN
It will have a circumference of around 100 km, giving a radius of around 16 km.
It may first be used for electron-positron collisions at 90 to 365 GeV per particle at high luminosity. It will be a "Higgs factory", a maker of lots of Higgs particles.
After some years of runs, it will be turned into a proton-proton collider, much like the LHC, but going up to 100 TeV per particle. That will be good for looking for Beyond-Standard-Model particles like supersymmetric ones, particles that the LHC has yet to make in recognizable fashion.
This upgrade will thus be much like LHC itself, which replaced the previous user of its tunnels, the The Large Electron-Positron Collider | CERN. The LEP accelerated these particles up to about 110 GeV of energy, thus giving them a relativistic energy factor of over 200,000. That meant that they traveled at 10^(-11) less than the speed of light in a vacuum, or 3 mm/s less.
This new accelerator would get them to a REF or gamma factor of over 700,000, making them travel at 10^(-12) less than c, or 0.3 mm/s slower.
Turning to protons, they won't quite go that fast, but their much greater energies allow possibly making more massive particles. Protons are composite, reducing the available energy by a factor of 3 or 4. That means about 2 GeV for the LHC, and a possible 30 GeV for the FCC.
