Towards control of a photoinjector by using spatial light modulators at FLUTE — •Carl Sax¹, Michael Nasse¹, Christina Widmann¹, Carsten Mai², Chenran Xu¹, Andrea Santamaria Garcia¹, Erik Bründermann¹, and Anke-Susanne Müller¹ for the FLUTE collaboration — ¹Karlsruhe Institute of Technology, Karlsruhe, Germany — ²TU Dortmund University, Dortmund, Germany

The characteristics of an electron bunch created with a photoinjector are strongly influenced by the properties of the driving laser. Therefore, we plan to install spatial light modulators (SLMs) in the laser beam path to shape and manipulate the infrared laser pulses, which are converted to the ultraviolet spectrum, and eventually also the generated electron bunch in the transverse as well as the longitudinal plane. SLMs should also allow the flexible mitigation of aberrations in the beam profile. The SLMs are planned to be installed in FLUTE (Ferninfrarot Linac- und Test-Experiment) at KIT, a compact linac-based test facility for accelerator R&D and source of intense THz radiation. In this presentation, the first test-setup is shown.
