Description

Beam-driven plasma wakefield accelerators allow for the generation and subsequent acceleration of electron beams inside the plasma
with substantially lower emittance than the driving electron beam, eventually providing technology for final-focus brightness converters for versatile applications. Among a variety of internal injection techniques, density downramp injection has the potential to reliably produce sub-micrometer emittance electron beams. The FLASHForward TW laser system allows for the ionization of wide plasma columns in a gas capillary and controlled density spikes, by selectively ionizing gas constitutes. This allows for shaping the plasma density profiles in order to control beam parameters.
We report on the recent progress in preparation and commissioning efforts for the optimization and realization of the generated electron beams.
