Merging Conventional and Laser Wakefield Accelerators — •Irene Dornmair^1,2, Benno Zeitler^1,2, Matthias Schnepp^1,2, Tim Gehrke^1,2, Julia Grebenyuk¹, Timon Mehrling¹, Jens Osterhoff¹, Klaus Flöttmann³, and Florian Grüner^1,2 — ¹Universität Hamburg — ²Center for Free-Electron Laser Science — ³Deutsches Elektronen-Synchrotron

Laser wakefield accelerators deliver high quality electron beams in terms of emittance and bunch length. However there are also parameters which cannot compete with conventional machines, namely spectral width and shot to shot stability.

One reason for that is that there is no direct access to the injection mechanism. Injecting a well-characterized electron beam produced by a conventional accelerator into a plasma wakefield could help to solve that problem, since such a pump-probe type experiment should allow for a direct reconstruction of the field distribution and a better understanding of the injection process.

REGAE at DESY in Hamburg is a suited accelerator for such a type of experiment. We report on the status of the beamline extension at REGAE and the plans towards the external injection project with the goal to directly measure the wakefield and further improve the stability of laser wakefield accelerators.
