Abstract: Litvinenko-Roser’s alternative approach for Future Circular electron-positron Collider uses energy recovery linac recirculators to mitigate the otherwise enormous power consumption needed to compensate for 100 MW of beam energy loss by synchrotron radiation in a ring-ring design. This approach would also allow to extend CM energy to 500 GeV (or above) for double Higgs production. An advantage of the linac-linac scheme is its allowing polarized beams. A 100 km, 220 GeV linear FFAG loop is subjected to bunch transport simulations, including SR and polarization survival.
