Visible Light Diagnostics at the ANKA Storage Ring — •Benjamin Kehrer, Edmund Hertle, Nicole Hiller, Michael Holz, Anke-Susanne Müller, Patrik Schönfeldt, and Paul Schütze — Karlsruhe Institute of Technology, Karlsruhe, Germany

Synchrotron radiation in the visible light range is a versatile diagnostics tool for accelerator studies. At the ANKA storage ring of the Karlsruhe Institute of Technology (KIT), we have a dedicated visible light diagnostics beamline and two additional beam ports close to the radiation's source point.The visible light diagnostics beamline hosts a time-correlated single-photon-counting unit to measure the bunch filling pattern and a streak camera for longitudinal diagnostics. Recently, the beamline has been extended with a fast-gated intensified camera to study transverse instabilities. The synchrotron light monitor ports were previously used for direct source imaging. Due to the diffraction limit the vertical beam size could not be resolved. One of the two ports has recently been equipped with a double-slit to allow for interferometric measurements of the vertical beam size. An overview of the different setup modifications will be given and first results will be presented.
