The trigger control system for the Obelix experiment

Meson spectroscopy and low energy antinucleon-nucleon interactions were studied in the Obelix experiment. A trigger control system was developed for the experiment which operates in a distributed environment and provides an easy to use mechanism for trigger selection. It has three basic characteristics of multiplicity, time-of-flight and topology selection. The trigger options work along parallel lines and any combination can be selected using the trigger control system.
