2h

Daejeon Convention Center

Poster Presentation MC1.A04 Plasma and wakefield acceleration Poster Session

Speaker

Spencer Gessner (SLAC National Accelerator Laboratory)

Description

The talk will detail pioneering work at SLAC’s FACET-II on using tailored, hollow plasma channels to create stable and efficient wakefields for accelerating positron beams—a longstanding and formidable challenge in plasma wakefield acceleration (PWFA) which has predominantly focused on electrons. This represents a critical step toward a viable, high-gradient positron source for a future linear collider, such as the ILC or CLIC. For a community driving the limits of beam energy and luminosity, mastering the co-acceleration of high-quality electron and positron beams within plasma is a transformative goal, essential for the next generation of particle physics discovery machines.
