dc.titleThe multilevel trigger system of the DIRAC experimenten
heal.abstractThe multilevel trigger system of the DIRAC experiment at CERN is presented. It includes a fast first level trigger as well as various trigger processors to select events with a pair of pions having a low relative momentum typical of the physical process under study. One of these processors employs the drift chamber data, another one is based on a neural network algorithm and the others use various hit-map detector correlations. Two versions of the trigger system used at different stages of the experiment are described. The complete system reduces the event rate by a factor of 1000 with respect to detectors' single rates, the detection efficiency of events in the relative momentum range of interest being greater than or equal to95%.
