Description
The HADES spectrometer is located at the SIS18 accelerator at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt. Recently an electromagnetic calorimeter (ECAL) detector was added to the set-up. The ECAL read-out system is based on the PaDiWa-AMPS Charge-to-Time-over-Threshold front-end board for the Trigger and Read-out Board (TRB) platform. The required discriminators, the high precision Time-to-Digital-Converters and the data acquisition functionality are implemented with the help of Field Programmable Gate Arrays. In this contribution the ECAL read-out system will be introduced and its performance will be shown. The possibility to use the TRB-platform for beam monitoring purposes will be addressed. Special emphasis will be put on new developments utilizing Ultra Fast Silicon Detectors for beam monitoring and T0 determination in HADES.
