THE USE OF THE SCINTILLATION HODOSCOPE IN THE FIRST-LEVEL TRIGGER OF THE SVD-2 SETUP TO SEARCH FOR CHARM PARTICLES IN HADRON-HADRON INTERACTIONS

A method for including the hodoscope of the SVD-2 setup in the first-l evel trigger is presented. Using the difference in the occupation of t he scintillation hodoscope planes with charged tracks from the charm-p roduction and background events, it is possible to highly enrich the s ample with the events with the charm-particle decays, The trigger may be optimized for extracting the charm events with the given decay mode . The numerical estimations were obtained by the Monte Carlo simulatio n of pp-interactions at 70 GeV/c, and according to the PYTHIA and GEAN T 3 programs.
