Abstract:

Superconductivity has been the key enabling technology for large accelerators in the last thirty years, allowing discovery of the Higgs boson at LHC in2012. This is giving ground to the technology development for upgrading LHC in luminosity and then in energy by means of very powerful SCi magnets and other SC devices like Crab Cavities and SC links. Recently a project aiming at 100 TeVproton collisions is gaining ground, called VHE-LHC. The concept and the technological challenge of these projects will be reviewed and a global plan to attain such goal is discussed.
