【 摘 要 】

The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) is a fixed target experiment designed to explore the QCD phase diagram in the region of high net-baryon densities. The CBM detector system will access beams directly from the superconducting synchrotrons SIS100 and SIS300. It is designed for interaction rates up to 107Hz to enable measurements of rare observables and diagnostic probes created in the early and dense phase of the fireball evolution. The layout of the CBM detector system is adapted to the experimental requirements concerning the acceptance in the laboratory frame (mid and forward rapidities), reaction rates, radiation tolerance, determination of the vertices with accuracy of 50 μm, particle densities (up to 700 particles passing through the active area of the detector in single central Au+Au collision at 25 GeV/nucleon) and selectivity [1, 2].
