Study Overview for Super Proton-Proton Collider

Abstract

SPPC (Super Proton-Proton Collider) is a discovery machine that is designed for energy frontier research in two decades from now, as the second stage of the CEPC-SPPC project. The main objective is to carry out experiments at 125 TeV in center-of-mass energy in a two-ring collider of 100 km in circumference and 20 T in dipole field. This white paper about SPPC describes the machine related issues, including performance, design overview, design challenges, key technologies and their maturity and required R&D, staged options and upgrades, synergies with other facilities, and environmental impacts.

RF Technologies for Future Colliders

“…For hadrons, the luminosity of the LHC will be upgraded first to the HL-LHC to improve the discovery reach of the machine at center-of-mass energies up to 14 TeV. The next-generation energy frontier hadron machines would be ~100-km circumference colliders FCC-hh [46] at CERN and SppC [47] in China, both of which have a target energy of ~100 TeV. However, to reach their design energies, these colliders need to develop superconducting magnet technology beyond state of the art that would take some time.…”
