Description
Recently, a high energy superconducting (SC) e+e− linear collider with energy recovery (ERLC) has been proposed, which uses twin RF structures to avoid parasitic collisions inside linacs. Such a collider can operate in a duty cycle (DC) or continuous (CW) modes (if sufficient power is available) with a luminosity of about 10^36) cm^−2 s^−1 at 2E_0 = 250−500 GeV. In this presentation I will update results on e+e- and for the first time consider a e−e− twin collider with energy recovery and estimate its achievable luminosity. Such collider is much simpler than an e+e− collider and can operate without beam recirculation with luminosity greater than 10^36 cm^−2 s^−1. The twin SC ERLC takes full advantage of linear colliders and is the best collider for studying Higgs properties.
