ARGUS - The scintillating fibre tagging detector of the BGO-OD experiment — •Stefan Alef and Björn-Eric Reitz for the BGO-OD collaboration — Physikalisches Institut, Nussallee 12, 53115 Bonn

The BGO-OD experiment at the ELSA accelerator in Bonn is built to investigate baryon-resonances using meson-photoproduction off the nucleon. The photons are produced from the electron beam via bremsstrahlung. Linearly polarized photons are obtained by coherent scattering off a crystal. The degree of polarization is obtained from the measured energy spectrum of the electrons. At the moment the energy resolution is limited by the current tagging system. Therefore an additional tagging detector consisting of scintillating fibres was constructed.
A short overview of the detector and its properties along with some preliminary first results will be shown.
