The BGO-OD experiment: data analysis in preparation for physics proposals — •Thomas Jude for the BGO-OD collaboration — Physikalisches Institut, University of Bonn, Bonn, Germany

The BGO-OD experiment at the ELSA accelerator facility, Bonn, consists of the highly segmented BGO calorimeter with a particle tracking magnetic spectrometer at forward angles. This allows the investigation of final states of mixed charge with nearly 4π acceptance, with very high precision at forward angles for charged particles.

An extensive physics programme using an energy tagged bremsstrahlung photon beam is planned using this unique setup. This includes measurements of associated strangeness, vector meson and pseudoscaler meson photoproduction.

The commissioning phase of the experiment is almost complete. This talk focuses on analysis of the commissioning data, which includes particle track reconstruction in the forward spectrometer and momentum reconstruction with the BGO calorimeter. Comparisons are made with simulated data, and analysis results relevant to the physics proposals are presented.
