Theory and measurements of emittance preservation in plasma wakefield acceleration
Frederico, Joel.
Plasma wakefield acceleration (PWFA) is a revolutionary approach to accelerating charged particles. In this dissertation, we present conditions for circular symmetry in the plasma wake. We present analysis of beam parameter and emittance matching, which predicts these values reach an equilibrium. We present and simulate a model for ion motion, and lay the foundation for simulations revealing emittance growth due to ion motion. By connecting a simple ion motion model and emittance theory, we calc... Show Full Abstract
Plasma wakefield acceleration (PWFA) is a revolutionary approach to accelerating charged particles. In this dissertation, we present conditions for circular symmetry in the plasma wake. We present analysis of beam parameter and emittance matching, which predicts these values reach an equilibrium. We present and simulate a model for ion motion, and lay the foundation for simulations revealing emittance growth due to ion motion. By connecting a simple ion motion model and emittance theory, we calculate the emittance growth due to marginal ion motion to be minimal. We also present a proof-of-concept of an emittance measurement of PWFA beams. Show Partial Abstract
