Cellular automaton track finder in realistic STS detector geometry

1ITEP, Institute for Theoretical and Experimental Physics, Russia;2GSI, Darmstadt, Germany; 3KIP, University of Heidelberg, Germany The cellular automaton (CA) based track finder of the CBM experiment [1, 2] is a flexible algorithm operating on space-points which makes it maximally independent of the actual geometry of the STS detector. Nevertheless, the requirements on the speed and accuracy of the algorithm due to its application at the trigger level force one to optimize and continually adjust the algorithm to the changing geometry of the STS detector and sometimes even influence the choice of the detector configuration. Following the recent developments of the STS detector several important modifications have been implemented in the CA track finder:
