Diagnostics of the FLUTE Gun Laser and Design of a Beam Transport System — •Sophie Walther, Erik Bründermann, Nicole Hiller, Anke-Susanne Müller, and Michael Nasse — KIT, Karlsruhe, Germany

FLUTE (Ferninfrarot Linac Und Test Experiment) is a new linear accelerator currently under comissioning at the Karlsruhe Institute of Technology (KIT). It is aimed at accelerator physics and THz radiation research. The electrons are generated with a photo-injector gun using picosecond long UV laser pulses. A Ti:Sapphire laser system with a consecutive third harmonic generation unit is used to generate the electrons. We present the design of a stabilized laser beam transport system to guide the laser to the cathode, including crucial diagnostic devices such as a 'virtual cathode' to monitor the laser beam. Additionally, first test results with the laser system will be presented.
