Commissioning of the new SciRi detector and reaction channel reconstruction at the BGO-OD experiment* — •Georg Scheluchin for the BGO-OD collaboration — Physikalisches Institut, D-53115 Bonn

The aim of the BGO-OD experiment is the investigation of non-strange and strange meson photoproduction. The setup combines a large aperture forward magnetic spectrometer covering the polar angles up to 12^∘ and a central BGO crystal calorimeter with a 25^∘ to 155^∘ polar angle acceptance. The acceptance gap between these two apparatus is a region which requires covering, as many final states under investigation have charged particles in this region.

The Scintillating Ring detector (SciRi) is a segmented plastic scintillator detector with Avalanche Photodiode readout designed to cover the polar angles between 10 and 25 degrees. The detector is segmented into 96 pieces, each covering Δ φ=11.25^∘ and Δ θ = 5^∘.

The increase in acceptance leads to a significantly increased detection efficiency of many photoproduction channels. The enhancement of meson identification such as ω, η and η′ using this new detector complementing the BGO-OD setup will be presented.
