Control software for the CBM readout chain — •Pierre-Alain Loizeau — GSI Helmholtzzentrum für Schwerionenforschung GmbH

The Compressed Baryonic Matter (CBM) experiment, which will be built at FAIR, will use free-streaming readout electronics to acquire high-statistics data-sets of physics probes in fixed target heavy-ion collisions. Since no simple signatures suitable for a hardware trigger are available for most of them, reconstruction and selection of the interesting collisions will be done in software, in a computer farm called First Level Event Selector (FLES).

The raw data coming from the detectors is pre-processed, pre-calibrated and aggregated in a FPGA based layer called Data Preprocessing Boards (DPB).

IPbus will be used to communicate with the DPBs and through them with the elements of the readout chain closer to detectors. A slow control environment based on this software is developed by CBM to configure in an efficient way the DPBs as well as the Front-End Electronics and monitor their performances.

This contribution will present the layout planned for the slow control software, its first implementation and corresponding test results.
