Description
The proposal for a new generation high-luminosity electron-positron collider, the Super Tau-Charm Facility (STCF), has been put forward in China. The STCF is expected to achieve a luminosity greater than 0.5×1035 cm-2 s-1 and operate within a center-of-mass energy range of 2 to 7 GeV. Considering the design challenges of the STCF collider ring, swap-out injection has been suggested as one of the alternative injection methods to achieve the desired luminosity. Therefore, the STCF injector will investigate both off-axis injection and swap-out injection methods concurrently. The demand for positron injection charge under swap-out injection is much higher than that of off-axis injection, requiring at least 300nC/s positron injection. Two positron source designs for both off-axis and off-axis injection will be presented in this paper.
