First results from commissioning of mCBM at GSI/FAIR — •Christian Sturm for the CBM collaboration — GSI, Darmstadt, Germany

To study extremely rare probes in nucleus-nucleus collisions with high precision, the Compressed Baryonic Matter experiment (CBM) at FAIR is designed to measure at unprecedented interaction rates up to 10 MHz. Hence, CBM will be equipped with fast and radiation hard detector systems, readout by a free-streaming data acquisition system, transporting data with up to 1 TB/s to a large scale computer farm, which provides first level event reconstruction and selection. To test and optimize all components and their complex interplay including firmware and software under realistic conditions the CBM full-system test-setup mCBM (”mini-CBM”) comprising pre-series components and final prototypes of all CBM detector subsystems and their read-out chains has been set-up at the present SIS18 facility of GSI/FAIR. With runs in March, November and December 2019 performed within the FAIR Phase-0 program the commissioning of mCBM has started. First results of the mCBM beam campaigns will be presented.

Supported by BMBF and GSI/FAIR.
