Time-based cluster and hit finding for the STS detector in the CBM experiment at FAIR — •Grigory Kozlov1,2,3,4 and Ivan Kisel1,2,3 for the CBM collaboration — 1Goethe University, Frankfurt am Main, Germany — 2Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany — 3GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany — 4Joint Institute for Nuclear Research, Dubna, Russia
The goal of the future CBM experiment at FAIR is to explore the QCD phase diagram in the region of high baryon densities using high-energy nucleus-nucleus collisions. An important feature of the experiment is the real time reconstruction and physical analysis. It will allow select important events immediately after the collision and increase the quality of the data. In this case, the data are supplied to processing in form of time slices containing a large number of collisions. Preprocessing of the time-based results requires special algorithms that take into account not only the coordinates, but also the time of flight of each particle. Clustering algorithm for the STS detector has been designed and integrated into the CBMROOT framework. It enables data processing with high efficiency for the time slices of any length at frequencies of 107 and over collisions per second. The algorithm has a high speed and it can operate in event-based mode as well as in time-based.
