Track Segments Reconstruction in Multiwire Drift Chambers System of HADES — •Geydar Agakishiev and Vladimir Pechenov — II Physikalisches Institut, Universität Gießen.

A fast and robust algorithm and software package for track segment reconstruction in the HADES multiwire drift chambers tracking system have been developed. The method consists of two parts. As a first step we search for groups of wires which are likely to belong to the same track and calculate a rough position of segments in space. At the next stage, taking into account the drift time measurements, the final position of track segments in space derived.

The presented software is heavily used for analysis of pp and AA data by the HADES collaboration. Some results of this analysis will be presented.
