General readout scheme for the HADES Electromagnetic Calorimeter: status and perspectives — •Behruz Kardan1, Adrian Rost2, and Ondřej Svoboda3 — 1Goethe-Universiät, Frankfurt am Main — 2TU Darmstadt, Darmstadt — 3Nuclear Physics Institute of ASCR, Rez, Czech Republic
The HADES spectrometer is located at the SIS18 accelerator at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt. An electromagnetic calorimeter for the HADES experiment is currently under design.
The calorimeter allows to measure neutral meson (π0 and η) production, which is essential for interpretation of dilepton data, but up to now unknown in heavy-ion reactions in the energy range of the planned FAIR experiments at SIS100.
In order to investigate the optimal functionality of the calorimeter module properties a series of dedicated test experiments of the prototype frontend-electronics in combination with different PMT types have been performed. In this contribution we present details of the detector layout, the module properties, the readout system and its performance studies.
