The EuroCirCol conceptual design study is a direct response to this recommendation, initiating a study for a 100 TeV energy-frontier circular collider
through a collaboration of institutes and universities worldwide.
Chief among them are the High Luminosity LHC, the Compact Linear Collider (CLIC), and the Future Circular Collider
The circular collider
creates new particles by smashing together protons and antiprotons traveling close to the speed of light; collisions reach energies of almost 2 trillion electron volts.
Preparations for the extended run, which would see the 27-kilometre circular collider
operating over three continuous years, are being finalized.
