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.
