Description
The Super Tau-Charm Facility is a high-luminosity electron–positron collider operating at a center-of-mass energy range of 2–7 GeV. The stringent requirements for beam brightness and stability pose significant challenges to the injector transport system, especially the positron transport lines of the damping ring. Beam transverse emittance is one of the primary parameters, which is influenced by a mass of components in the lattice design. In this study, a newly developed multistage optimization method is employed to optimize multiple sets of quadrupole strengths along the transport line. The optimized results effectively suppress the emittance growth and maintain compliance of other parameters with damping ring requirements. These results provide a practical reference for the optical design of high-brightness transport systems in next-generation electron–positron colliders.
