Implementation of a MiniTAPS Trigger Board for the CBELSA/TAPS Experiment — •Lisa Richter, Annika Thiel, Janis Hoff, and Christian Honisch for the CBELSA/TAPS collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn

Baryon spectroscopy is performed with the CBELSA/TAPS experiment through the study of reactions that are produced with a photon beam impinging on a nucleon target. The detector setup is optimized for the production of neutral mesons which decay mainly in photons.
The MiniTAPS calorimeter is located in the forward region and is therefore one of the central parts of the detector system. It covers the forward angle between 1^∘ and 12^∘ and can capture photons with energies between 10 MeV and 2.0 GeV.
The detector consists of 216 hexagonal BaF2 crystals which are read out via photomultiplier tubes. To avoid wrong information due to overlapping clusters, the crystals are arranged in four sectors and the number of hits in a sector in one event is determined by the trigger.
The new MiniTAPS trigger is currently developed to replace the old MCU (multiple coincidence unit) electronics. It will be realized by a single FPGA in a VME module. This will not only simplify the electronics but also allow for more sophisticated trigger algorithms including e.g. a fast cluster finder.
The new setup of the trigger and first results of the analysis will be presented on this poster.
