Abstract: We propose a full-system test-setup for the Compressed Baryonic Matter experiment CBM atSIS18 under the name mCBM@SIS18 (“mini-CBM”, later shortened to “mCBM”), comprisingfinal prototypes or pre-series components of all CBM detector subsystems. The primary aim is tostudy, commission and test the complex interplay of the different detector systems with the freestreamingdata acquisition and the fast online event reconstruction and selection. In particular, itwill allow to test the detector and electronics components developed for the CBM experiment aswell as the corresponding online/offline software packages under realistic experiment conditionsup to top CBM interaction rates of 10MHz.Commissioning and operating mCBM in 2018 and 2019 will prove the proper functioning ofthe detectors as well as the read-out electronics before the final series production starts. Theexperiences gathered during the operation of the complete mCBM campaign will be of highestvalue to minimize the commissioning time for the full CBM experiment at SIS100.With mCBM, the ambitious detector sub-systems, readout and data processing concept of CBMwill be validated on the base of a benchmark observable, namely the Λ production yield inAu+Au and Ni+Ni collisions at top SIS18 energies, which can be compared to publisheddata. The feasibility has been successfully demonstrated by performing Monte-Carlo simulationsincluding GEANT geometries of all mCBM detector subsystems and full detector response.
