The HADES detector upgrades: Current status and future perspectives — •Adrian Rost for the HADES collaboration — TU Darmstadt

The HADES spectrometer at GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt was recently upgraded with new detector components. Besides a technical upgrade of the photon detector of the Ring-Imaging-Cherenkov (RICH) system a new electromagnetic calorimeter (ECAL) was installed in the spectrometer. 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 systems under beam conditions will be presented. For future operations at the SIS18 accelerator HADES has a broad physics program which is mainly focused on pion/proton induced reactions. For these upcoming experiments T0 and new beam detectors utilizing Ultra Fast Silicon Detector (UFSD) technology will be used, front-end electronics of HADES tracking system will be upgraded and a new forward tracking system will be installed.
