The HADES electromagnetic calorimeter upgrade: Current status and future perspectives* — •Adrian Rost for the HADES collaboration — FAIR GmbH, Darmstadt, Germany — TU Darmstadt, Darmstadt, Germany

The HADES spectrometer at GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt was recently upgraded with a new electromagnetic calorimeter (ECAL). In March 2019 a four week physics production beam time with an "Ag+Ag" beam at 1.58A GeV was carried out. In this contribution the performance of the new detector system under beam conditions will be presented. Particular emphasis will be put on its FPGA-TDC based read-out electronics and the performance.
