Description

The Super Tau-Charm Facility (STCF) is a new generation tau-charm factory designed to collect an enormous and unique dataset in the tau-charm energy region. In order to supply high-quality electron and positron beams to the collider, the STCF injector employs a compatible injector scheme that supports both off-axis and swap-out injection modes. This paper introduces the conceptual design of a combined damping and accumulator rings for positrons at the STCF, aimed at meeting low-emittance beam requirements. Within this system, the damping ring is optimized for off-axis injection, while the accumulator ring is designed for swap-out injection. Detailed injection and extraction schemes for both rings are also presented and discussed.
