Phase-Space Dynamics of Ionization Injection in Plasma-Based Accelerators
Phase-Space Dynamics of Ionization Injection in Plasma-Based Accelerators
The evolution of beam phase space in ionization injection into plasma wakefields is studied using theory and particle-in-cell simulations. The injection process involves both longitudinal and transverse phase mixing, leading initially to a rapid emittance growth followed by oscillation, decay, and a slow growth to saturation. An analytic theory for …
