Description
Beam-driven plasma wakefield acceleration (PWFA) holds considerable promise for next-generation electron-positron colliders and high-energy free-electron lasers, owing to its ultrahigh accelerating gradients. To address fundamental physics and technical challenges associated with both electron and positron acceleration in PWFA, the Institute of High Energy Physics (IHEP) has established a plasma wakefield acceleration experimental platform based on the Beijing Electron-Positron Collider (BEPCII). The platform comprises two beamlines and a petawatt laser system. Beamline I deliver electron and positron beams from BEPCII to the experimental area, while Beamline II is a newly constructed 150 MeV high-performance linear accelerator. Together, these beamlines support a range of plasma acceleration experiments, including positron acceleration, electron-cascade acceleration, high transformer-ratio electron acceleration, and external-injection electron acceleration. Notably, Beamline II is capable of generating electron beams with a bunch charge exceeding 5 nC and a peak current above 10 kA. This paper presents a detailed overview of the physics design and current progress of beamlines.
