Technical commissioning of AGATA at GSI: coupling of the DAQ* — •Damian Ralet¹, Stephane Pietri², Hakan Johansson³, Dino Balzzacco⁴, Xavier Grave⁵, Nikolaus Kurz², Yann Aubert⁵, Nicolas Dosme⁵, Amel Korichi⁵, Eric Legay⁵, Juergen Gerl², and Norbert Pietralla¹ — ¹Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany — ²GSI Helmholtzzentrum für Scherionenforschung GmbH, Darmstadt, Germany — ³Chalmers University of Technology, Göteborg, Sweden — ⁴Istituto Nazionale di Fisica Nucleare Sezione di Padova, Padova, Italy — ⁵CSNSM Université Paris-Sud, Orsay, France

The PRESPEC experiment for high-resolution gamma-ray spectroscopy using radioactive ion beams at the FRagment Separator of GSI together with the LYCCA-1 calorimeter and the AGATA [1] detector array has been commissioned early 2012. Main goals of the commissioning were to test the new trigger logic using FPGA-based modules and to test the coupling of the two data acquisition systems, NARVAL for the AGATA detectors, and MBS for the FRS+LYCCA detectors. The performance of the DAQ coupling will be presented and various trigger configurations for background suppression will be discussed.
