Europe unveils successor to the Large Hadron Collider – Physics World
They are trying to decide whether they want a linear collider or a circular collider.

The Future Circular Collider | CERN - will have a circumference of 100 km, instead of the LHC with 27 km. It will be in a tunnel around Geneva, and it will pass near the LHC, which will serve as a booster for it.
The LHC itself is being upgraded for high beam luminosity, giving the HL-LHC, and it will be run in this form until 2035, when the statistics of its data will increase too slowly to make it economical to run for much longer. That is because the relative error of measurement behaves as 1/sqrt(N) for N events. By then, the LHC's successor should be ready.
The first version of the FCC will be the FCC-ee. It will collide electrons and positrons, and it will go up to 400 GeV CM energy. That will get up to the mass-energy of top-antitop pairs, particle-antiparticle pairs for the heaviest Standard-Model particle, the top quark.
After some years of running it, it will be converted to a hadron collider, the FCC-hh. It will collide protons, and it will go up to 100 TeV CM energy. Thus being like the LHC, which was built in its predecessor LEP's tunnels. By comparison, the canceled SSC would have gone up to 40 TeV CM energy.
The FCC-hh would be good for looking for supersymmety partners of Standard-Model particles a little above the Standard Model particles' energies, especially the QCD-interacting ones, the squarks and gluinos. The LHC has failed to find any such particles over the time that it has been running, however, getting up to 1.5 TeV for the squarks and 2 TeV for the gluinos. Lower limits for non-QCD SUSY particles are much lower. The FCC-hh would be able to make detectable squarks and gluinos with masses up to 12 - 17 TeV.
These accelerator planners will likely decide on an option in the next few years, so that construction can start on a LHC successor in time to take over from the LHC.
