摘要：
A new software trigger system was developed and installed at the TOPAZ detector to the trigger system for the TRISTAN e+e- collider to take data efficiently in the scheduled high luminosity experiment. This software trigger requires two or more charged tracks originated at the interaction point by examining the timing of signals from the time projection chamber. To execute the vertex finding very quickly, four microprocessors are used in parallel. By this new trigger the rate of the track trigger was reduced down to 30-40% with very small inefficiency. The additional dead time by this trigger is negligible.
