Toward a demonstrator of the free-streaming data acquisition system for the CBM experiment at FAIR — •Pierre-Alain Loizeau and David Emschermann for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH

The Compressed Baryonic Matter experiment (CBM) will be based at the new Facility for Antiproton and Ion Research (FAIR), which will deliver heavy-ion beams up to energies of 14 A GeV. In nucleus-nucleus collisions at these beam energies strongly interacting matter with densities up to 10 times normal nuclear matter is expected to be produced. The key objective of CBM is to investigate the QCD phase diagram in the region of high baryon-densities. CBM is designed to cope with very high interaction rates up to 10 MHz. This will allow to perform high precision measurements of extremely rare probes which have not been accessible by previous nucleus-nucleus experiments in this energy regime. To achieve the high rate capability CBM will be equipped with fast and radiation hard detectors employing free-streaming readout electronics. A prototype high-speed Data Acquisition (DAQ) system was used for some of CBM subsystems in 2016 and 2017, based on a combination of microTCA (uTCA) and PCIe FPGA boards. A full prototype of the DAQ system using in addition the CERN radiation hard ASIC GBTX will be used for the phase 1 of the mCBM@SIS18 (“mini-CBM”) setup in 2018. For mCBM phase 2 in 2019, it will be upgraded to a close to final demonstrator system with a single PCIe board replacing the uTCA and PCIe ones. We will report on the progress in the preparation of these DAQ setups.
