Description
The Super Tau-Charm Facility (STCF) is a next-generation electron-positron collider under development, with a designed center-of-mass energy of 2–7 GeV. Positrons generated by a high-energy electron beam striking a target are captured and accelerated to 200 MeV using large-aperture traveling-wave accelerating structures to reduce beam loss. A constant-aperture cavity geometry, in which the group velocity is controlled by the nose-cone length, is proposed to simplify fabrication while maintaining a high accelerating gradient. A pulse compressor is incorporated into the RF system to further enhance the effective RF power. This paper presents the RF design and optimization of 2 m and 3 m large-aperture accelerating structures, both achieving gradients above 15 MV/m.
