FCC-ee: Electron–Positron Factory
A precision lepton collider serving as a Higgs, electroweak, and top-quark factory. Operating at center-of-mass collision energies across $Z$, $W$, $Higgs$ ($240\text{ GeV}$), and $t\bar{t}$ threshold ($365\text{ GeV}$).
- Ultra-high luminosity per collision point
- Civil & technical infrastructure shared for Stage 2
- Total Construction Budget: ~15 Billion Swiss Francs
FCC-hh: Proton–Proton Hadron Collider
A massive hadron collider operating in the same 91 km tunnel, utilizing advanced superconducting magnets (16–20 Tesla) to reach an unprecedented collision energy of roughly $100\text{ TeV}$.
- Direct discovery reach for heavy dark particles up to tens of TeV
- High luminosity proton-proton and heavy ion operational modes
- Synergy with heavy-ion physics (Lead & Oxygen/Neon ion runs)
