Description

The linac-based test facility FLUTE (Ferninfrarot Linac- Und Test-Experiment) at the Karlsruhe Institute of Technology (KIT) was designed as a test bench for accelerator technologies with a broad range of beam parameters. The electron bunches are generated in a UV photo-injector which offers laser pulse shaping as control of the beam parameters. The imprint of a transverse laser profile modulated by an spatial light modulator (SLM) onto the electron bunch was demonstrated at the low energy section of FLUTE. The addition of the linear acceleration structure and bunch compressor section, as well as the upgrade of the RF system, enables experiments with short-pulse electron bunches up to 90 MeV.
For this contribution, the SLM was used to recreate the modified electron bunch profile and we present the observed characteristics after passing the traveling-wave RF structure and magnetic chicane.
