Beam Transport and Stabilization System for the FLUTE Gun Laser — •Sophie Walther1, Erik Bründermann3, Stefan Funkner1, Anke-Susanne Müller2, Michael Nasse1, and Gudrun Niehues1 — 1LAS, KIT, Karlsruhe — 2ANKA, IPS, LAS, KIT, Karlsruhe — 3IPS, KIT, Karlsruhe
The linear accelerator of FLUTE (Ferninfrarot Linac- Und Test-Experiment) is currently under commissioning at the Karlsruhe Institute of Technology. It is planned to use strong femtosecond to picosecond UV pulses for the photoinjection of electrons from the cathode into the linear accelerator structure. For this purpose a femtosecond laser system is located in a distance of more than 30 meters in a clean room environment. This study investigates the performance of optical setups to reach a stable optical layout for transport of the femtosecond to picosecond laser pulses to the cathode. To compensate drifts and movements of the laser beam over the more than 30 meters a stabilization system is evaluated and tested. The results of these measurements are presented in this contribution.
