On-line event selection with the FAMP microprocessor system
Description
In the experiment NA11 at the CERN SPS the MC68000 based FAMP system has been successfully implemented in a second stage trigger. It was used in a study of inclusive phi-meson production to select phi → K+K- decays by determining the charged K-meson trajectories and calculating the K+K- invariant mass. A trigger rate reduction by a factor of 25 and an increase in the number of recorded phi-decays per unit time by a factor of 8 has been achieved. (Auth.)
