Description
To generate the electrons to be accelerated, a photoinjection
laser is used at the linac-based test facility FLUTE
(Ferninfrarot Linac- Und Test Experiment) at the Karlsruhe
Institute of Technology (KIT). The properties of the laser
pulse, such as intensity, laser spot size or temporal profile,
are the first parameters to influence the characteristics of
the electron bunches. In order to control the initial parameters
of the electrons in the most flexible way possible, the
laser optics at FLUTE are therefore supplemented by additional
setups that allow transverse and longitudinal laser
pulse shaping by using so-called Spatial Light Modulators
(SLMs). In the future, the control of the SLMs will be integrated
into a Machine Learning (ML) supported feedback
system for the optimization of the electron bunch properties.
In this contribution the first test experiments and results on
laser pulse shaping at FLUTE on the way to this project are
presented.
