Description
Summary:The 'Compressed Baryonic Matter' (CBM) experiment at the new 'Facility for Antiproton and Ion Research' (FAIR) in Darmstadt is designed to study the properties of highly compressed baryonic matter produced in nucleus-nucleus collisions in the 10 to 45 A GeV energy range. One of the key observables is hidden (J/ψ) and open (D°, D±) charm production. To achieve an adequate sensitivity extremely high interaction rates of up to 107events/second are required, resulting in major technological challenges for the detectors, front-end electronics and data processing. The front-end electronics will be self-triggered, autonomously detect particle hits, and output hit parameter together with a precise absolute time-stamp. Several layers of feature extraction and event selection will reduce the primary data flow of about 1 TByte/sec to a level of 1 GByte/sec. This new architecture avoids many limitations of conventional DAQ/Trigger systems and is for example essential for open charm detection, which requires the reconstruction of displaced vertices, in a high-rate heavy ion environment.
