Status of the mCBM@SIS18 experiment at GSI/FAIR — •Christian Sturm for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH

The Compressed Baryonic Matter experiment (CBM) at FAIR is consequently designed to measure nucleus-nucleus collisions at unprecedented interaction rates up to 10 MHz which will allow to study extremely rare probes with high precision. To achieve this high rate capability CBM will be equipped with fast and radiation hard detectors, readout by a free-streaming data acquisition system transporting data with up to 2 TB/s to a large scale computer farm which provides first level event selection. With mCBM@SIS18 (“mini-CBM”) we are presently commissioning a CBM full-system test-setup at GSI/FAIR comprising final prototypes and pre-series components of all CBM detector subsystems and their read-out systems. The primary aim is to develop, commission and optimize (i) the free-streaming data acquisition system including the data transport to a high performance computer farm inside the GreenITCube, (ii) the online track and event reconstruction and event selection algorithms and (iii) the offline data analysis as well as the controls software package. Furthermore, the setup offers additional high-rate tests of the final detector prototypes in nucleus-nucleus collisions under realistic experiment conditions. An overview on the mCBM@SIS18 project incl. first results from the commissioning runs will be given.
