The Future Circular Collider electron-positron (FCC-ee) injector linacs and positron source are critical components for delivering high-quality beams to the collider. This work presents studies on key dynamic effects influencing beam stability, including single- and multi-bunch instabilities. A detailed analysis of multi-bunch beam loading is conducted, considering trains of arbitrary bunch...

The Circular Electron Positron Collider (CEPC) is a 100-km electron-positron collider designed as a Higgs factory. Its accelerator complex comprises a 30-GeV Linac, a full-energy booster, two collider rings, and several transport lines. To mitigate the challenges associated with low-energy design for the booster and to manage costs effectively, the Linac is tasked with delivering electrons and...

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 0.5×10^35 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...

Intense positron source is a one of the key component for the next electro positron collider. Recently, several groups actively discuss and develop such positron sources for FCC, CEPC and ILC. On the other hand, basic design of positron source have not changed for more than 30 years since the one developed for the SLC. In addition, only a few positron sources are in operation now. In this...

The next generation of lepton colliders demands machine luminosities in the range of 10³⁴ to 10³⁶ cm⁻²s⁻¹, requiring electron sources capable of delivering bunch charges of several nanocoulombs at injection rates of tens to hundreds of bunches per second. Achieving such high charge levels requires careful optimization of the electron source to maximize injection efficiency. This talk explores...
