Numerical studies for optimized ionization injection

The LUX beamline is a novel laser-plasma accelerator, built in close collaboration of the University of Hamburg and DESY, and dedicated for the generation of laser-plasma driven undulator radiation. Separating the injection of electrons from the acceleration in the plasma is crucial for improved control over the electron beam phase space. Here, we present numerical studies on ionization injection with a focus on the separation of the injection and acceleration sections, while optimizing experimentally accessible parameters for improved electron beam quality.
