Laser alignment of internal components of the linear accelerator FLUTE — •Jens Schäfer, Bastian Härer, Matthias Nabinger, Michael J. Nasse, Robert Ruprecht, Nigel J. Smale, and Anke-Susanne Müller — KIT, Karlsruhe, Deutschland

The linac-based test facility FLUTE (Ferninfrarot Linac- Und Test Experiment) at KIT will be used to study novel accelerator technology and provide intense THz pulses. The latest experiments involving a Split Ring Resonator for longitudinal bunch profile measurements pushed the requirements on alignment precision of several hardware components down to the sub-milimeter level. In order to achieve the required precision, the low energy section of FLUTE was opened and an alignment laser was installed to mark mechanical axis of the machine. This presentation addresses details and challenges of this laser-based alignment process.
