The Upgrade of the HADES Data Acquisition System* — •Jan Michel1,2, Ingo Fröhlich1, Kathrin Göbel1,2, Christian Müntz1, Marek Palka1, Joachim Stroth1, Attilio Tarantola1, Michael Traxler2, and Sergey Yurevich21Institut für Kernphysik, Goethe-Universität Frankfurt am Main — 2GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt

The main goal of the HADES upgrade is increasing the event rate capability up to 20 kHz for heavy ion collisions. This results in a data rate of about 250 MByte/s for heavy collision systems and an event rate of 100 kHz for light systems.

During this upgrade, most parts of the data acquisition system have been replaced. The new electronics is based on the latest FPGA architectures to gain highest data rates combined with low latency and high flexibility to adapt to front-end electronics. Data is now mainly transported through optical fibres to minimize the amount of noise introduced in analog signals. The monitoring and controlling capabilities have been increased by employing a unified network setup throughout all subsystems.

In this talk, an overview of the new DAQ system and the technologies involved will be given. The current status of the upgrade including first performance measurements gathered during the commissioning will be shown.
