Performance of the CBELSA/TAPS Experiment — •Christoph Wendel — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn
To perform double polarisation experiments at the electron accelerator ELSA in Bonn (aiming at a good understanding of the hadron spectrum), the experimental setup of the Crystal-Barrel-Experiment was subject to several modifications.
They include the relocation to a different experimental hall, a longitudinal polarised target, a new photon tagging system, the refurbishment of the 30∘ forward angle of the Crystal-Barrels CsI(Tl) calorimeter, a modular gas/aerogel Cerenkov detector and modifications to the TAPS BaF2 calorimeter wall.
The talk will cover these modifications and extensions of the setup and discuss the performance of the experiment.
