Description
The FCC-ee injector complex is designed to deliver tunable, high-charge electron and positron bunches for injection into the collider over a center-of-mass energy range of 90--365~GeV. A key element is the high-energy (HE) linac, which accelerates the beam from about 3 to 20~GeV before injection into the booster. In this work, we present beam-dynamics studies aimed at minimizing emittance growth and improving transverse stability along the HE linac. Different lattice configurations, phase advances, and RF layouts were investigated to identify an optimized design. The selected configuration satisfies the present performance requirements for efficient booster injection and supports the operational goals of the FCC-ee injector complex.
