Abstract :
A new track-finding algorithm for use with the TOPAZ time projection chamber (TPC) has been developed. The logic not only finds the number of tracks, but also calculates their vertex positions. It takes care of the sector boundary crossing tracks. Test results for a prototype TPC trigger are reported. Vertex resolution of less than 10 cm (RMS) in the beam direction was achieved.
