Plasma Wakefield Acceleration (PWA) promises to reduce the scales of advanced light sources and high-energy colliders due to its ultrahigh accelerating gradients. However, the relatively large energy jitter and energy spread (typically 1~10% level) of the electron bunches generated by PWAs remain a major obstacle for practical applications. In this work, we propose two independent schemes: 1)...
The Circular Electron-Positron Collider (CEPC) is a dual-ring accelerator with a design circumference of 100 kilometers, prioritizing operation at the Higgs particle energy (center-of-mass energy of 240 GeV). To achieve its high-luminosity collision goals, the CEPC accelerator physics team addresses core challenges through design optimization, including beam optics design under strong...
TThe injector of the Super Tau-Charm Facility (STCF) should provide high-quality electron and positron beams for the collider ring according to different injection schemes, which is one of the key systems to ensure the high brightness of STCF. This paper presents the preliminary physical design and beam dynamics optimization of the complex beam transport system, which interconnects the main...
