Summary
A two-level trigger is to be applied for suppression of the background and for effective selection of events involving short-lived Λ-, Σ- and φ-particles in the experiment DISTO. The first-level trigger is intended for selection of events by their multiplicity. The second-level trigger is applied for track recognition, in searching for a secondary vertex, and for identifying the detected particles.
